An EDOF IOL (Extended Depth of Focus intraocular lens) is a premium cataract lens that creates a continuous elongated focal zone rather than separate focal points. It provides clear, sharp vision from distance to intermediate — computer, dashboard, kitchen — with significantly fewer halos and starbursts than trifocal lenses. EDOF lens price in India in 2026 ranges from ₹35,000 to ₹80,000 per eye (including surgery at private hospitals) for imported brands; Indian-manufactured EDOF options like the X-VIZ by Agaaz Ophthalmics are available at lower cost. EDOF suits patients who drive frequently, spend time at screens, and want fewer optical disturbances — but near reading at small print may still require glasses. It is not suitable for patients with active dry eye, keratoconus, or macular disease.
How EDOF Actually Works:
Stretching a Single Focus Into a Range
Standard monofocal lenses have one focal point — set at distance. Everything closer than about 6 metres needs glasses. Multifocal lenses create two or three discrete focal points using concentric diffractive rings — good for near and distance, but the multiple images cause more scatter and the characteristic starbursts around night lights.
EDOF takes a different approach. Instead of creating multiple separate foci, it elongates the single focal zone — stretching it from distance through arm's length in a continuous gradient. The technology achieves this through several mechanisms depending on the manufacturer's design:
- Diffractive EDOF (single diffraction order): A single low-power diffractive step extends depth of focus. Used by J&J Tecnis Symfony (first FDA-approved EDOF IOL, 2016). The echelette design directs light into a focused elongated zone while minimising destructive interference at other focal points.
- Refractive EDOF: Asphericity and zone design shape the wavefront to extend focus. Used in several European EDOF designs (Zeiss AT Lara, Rayner RayOne EMV). Less dependent on pupil size than diffractive designs.
- Pinhole / small aperture EDOF: A small central aperture acts like a camera's depth-of-field mechanism. Excellent for irregular corneas. AcuFocus IC-8 Apthera is the clinical example.
- Hybrid EDOF-trifocal: Combines EDOF elongation with near addition — attempting the best of both. J&J Tecnis Synergy, classified differently by different bodies. Near vision better than pure EDOF; halos somewhat higher.
The result is an extended range of clear vision — typically 6 metres to about 60–80 cm (arm's length / laptop screen distance) — without the discrete focal jumps of multifocal designs. Fine near work (phone screen text, reading book print) is where patients notice the limitation: some use occasional low-power reading glasses for sustained fine near work.
FOCAL RANGE COMPARISON: MONOFOCAL vs EDOF vs TRIFOCAL
"EDOF IOLs represent the most significant advancement in presbyopia correction since the introduction of multifocal IOLs — not because they eliminate spectacle dependence, but because they fundamentally change the tradeoff patients must accept between optical quality and visual range."

EDOF captures the lifestyle that defines most of India's urban cataract patients today: driving on highways, working on laptops, cooking dinner, watching TV — all activities in the distance-to-intermediate range. The activities where EDOF falls short (reading a medicine packet, stitching, fine jewellery work) represent a smaller fraction of daily visual demand. A patient who asks "will I need glasses after surgery?" will likely get an honest "rarely, but sometimes for fine print" with EDOF — which is a far better answer than the same question answered with a monofocal ("yes, always for everything close").
EDOF Lens Price in India 2026:
What You Actually Pay
Pricing for EDOF IOLs in India varies substantially by lens origin (imported vs Indian-manufactured), hospital tier, and whether the price includes surgery or just the lens. Here is a realistic breakdown based on current market data.

|---|---|---|---|---|
| J&J Tecnis Symfony | USA (imported) | Diffractive EDOF (echelette) | ₹55,000–₹85,000 | Major private hospitals |
| J&J Tecnis Synergy | USA (imported) | Hybrid EDOF-trifocal | ₹65,000–₹1,00,000 | Major private hospitals |
| Zeiss AT Lara | Germany (imported) | Refractive EDOF | ₹55,000–₹75,000 | Selective private centres |
| Hoya Vivinex iSert 250 (EDOF) | Japan (imported) | Refractive EDOF asphericity | ₹45,000–₹65,000 | Mid to high-tier hospitals |
| Alcon Clareon PanOptix (trifocal, EDOF-adjacent) | USA (imported) | Trifocal diffractive | ₹60,000–₹90,000 | Major private hospitals |
| X-VIZ — Agaaz Ophthalmics | India (Ahmedabad — GMP certified) | Trifocal / EDOF — Indian manufactured | Significantly lower — contact Agaaz for hospital pricing | India + 15+ export markets via Agaaz distributor network |
| Government/AIIMS/RIO (subsidised) | Various | Government procurement varies | ₹500–₹5,000 (patient co-pay) | Government hospitals — select centres only |
When a hospital quotes you an EDOF IOL price, confirm whether it covers: the lens itself; surgeon fees; OT charges; anaesthesia; pre-operative investigations (biometry, keratometry, topography); post-operative medications (antibiotic drops, steroid drops, NSAIDs); and follow-up visits. Prices advertised as low as ₹20,000 often cover only the lens cost without surgery. Prices quoted at ₹1,00,000+ at premium hospitals include the full package. Ask for an itemised quote and compare like-for-like.

X-VIZ: Agaaz Ophthalmics'
Trifocal / EDOF IOL — Made in India
The X-VIZ is Agaaz Ophthalmics' premium EDOF/trifocal intraocular lens, manufactured in Ahmedabad, Gujarat under GMP-certified conditions. It positions Indian cataract surgery — in both private and government settings — to offer trifocal and extended depth-of-focus technology without being locked into imported product pricing.
For surgeons managing high-volume cataract camps, charitable eye hospitals, or government procurement: X-VIZ makes premium IOL technology accessible at Indian manufacturing cost structures, enabling clinics to offer EDOF to a broader patient population than import pricing permits. For private hospitals: X-VIZ provides a reliable GMP-certified EDOF lens with full documentation for regulatory compliance.
Agaaz Ophthalmics also manufactures the full peri-surgical toolkit that X-VIZ implantation requires: OP-VIEW AS (hydrophobic foldable IOL for standard cases), OP-FOLD AS (hydrophilic foldable), PURE-HYAL (sodium hyaluronate OVD for endothelial protection during implantation), and MOXGUARD (intracameral moxifloxacin endophthalmitis prophylaxis).
The Tradeoff Nobody Shows You:
What Night Lights Actually Look Like
Every premium IOL produces some degree of photic phenomena — halos, starbursts, or glare around bright lights at night. The question isn't whether you'll see them: it's how large, how bright, and whether your brain will neuroadapt to them over time. EDOF produces less photic phenomenon than trifocal multifocal by most measures — but it's not zero.
Neuroadaptation is the process by which the brain learns to filter out photic phenomena that were initially noticeable. Published data shows that ~85% of EDOF patients who report halos at 1 month report minimal or absent halos at 12 months. The neuroadaptation window is generally 3–6 months for EDOF, longer for trifocal. Patients who have been counselled to expect halos and who understand they will diminish have substantially higher satisfaction scores than those who were not warned.
The patients for whom halos do not diminish to acceptable levels — about 5–8% of EDOF patients in published series — are those with large pupils, prior corneal surgery, significant residual refractive error post-implantation, or simply a predisposition toward photic sensitivity. Pre-operative counselling that establishes realistic expectations is the most powerful tool surgeons have for managing this.
Who Should Get an EDOF?
The Honest Answer
Good EDOF Candidates
- Drivers — particularly those who drive at night. EDOF's lower halo profile makes it substantially more suitable than trifocal for regular night drivers.
- Screen-dominant workers — IT professionals, engineers, office workers, doctors who spend most of their working day at computer screens (60–80 cm range where EDOF shines).
- Active outdoor lifestyle — golfers, cyclists, cricket watchers — primarily need distance with good intermediate for positioning and movement.
- Patients with prior photophobia concerns — anyone who reports sensitivity to bright lights or glare will likely tolerate EDOF better than trifocal.
- Regular corneas with minimal astigmatism — EDOF optical design requires a good corneal surface. Patients with <1.5D of regular astigmatism are ideal; with 1.5–3D, a toric EDOF should be considered.
- Patients with realistic expectations — specifically: comfortable knowing they may occasionally use reading glasses for fine near work. Patients who understand and accept this are excellent candidates.
Poor EDOF Candidates — Choose a Different Lens
- Active dry eye disease — the tear film instability in DED creates a variable, irregular corneal surface that disrupts EDOF optics. This is contraindicated. Treat DED to stability before considering premium IOL. See our Dry Eye Disease guide.
- Keratoconus or irregular astigmatism — any corneal irregularity significantly degrades EDOF outcomes. The elongated focal zone design is highly sensitive to aberrations that an irregular cornea introduces.
- Macular disease (AMD, diabetic maculopathy) — premium IOLs of any type deliver their benefits through retinal image quality; macular disease compromises the retina's ability to resolve those images regardless of IOL design.
- Patients who depend heavily on near vision for work — jewellers, tailors, microsurgeons, dentists — whose livelihood requires sustained fine near work. Monofocal or combined monovision strategy is safer.
- Severe glaucoma — reduced contrast sensitivity from glaucoma makes patients less likely to benefit from the contrast tradeoffs in premium IOLs.
- Very high expectations of complete spectacle independence at all distances — if a patient truly insists on reading the newspaper without any glasses, trifocal is their lens (and they should be counselled on halos). EDOF will disappoint them for fine near work.
What the Procedure Looks Like:
Nothing Unusual. Same Day Home.
EDOF IOL implantation uses the same phacoemulsification technique as any other premium IOL. There is no special surgical approach for EDOF — the premium is in the optical design of the lens, not in the surgical method. Standard 2.2–2.8 mm clear corneal microincision phacoemulsification, cortical clean-up, and IOL implantation into the capsular bag using an injector.
What does matter specifically for EDOF: precise biometry. The EDOF focal range extends from distance to intermediate, but the exact placement of that range depends on accurate IOL power calculation. A 0.5D residual refractive error — acceptable with a monofocal where the patient simply updates their glasses — is clinically meaningful with an EDOF because it shifts the entire elongated focal zone. Modern optical biometry (IOLMaster 700, Lenstar, Pentacam-integrated calculations) and modern IOL formulas (Barrett Universal II, Kane, Hill-RBF) should be used. Keratometry from topography, not just manual K readings.
- Anaesthesia: Topical (eye drops) — no injection, no patches, awake throughout. Comfortable for the vast majority of patients.
- Duration: 15–25 minutes per eye at a skilled surgeon's hands. Same day discharge. No hospitalisation.
- Recovery: Vision improves within hours. Full EDOF benefit appreciated as the brain adapts — typically 1–3 months for full visual quality optimisation.
- Post-operative regimen: Antibiotic + steroid + NSAID drops for 4–6 weeks. MOXGUARD (intracameral moxifloxacin) at the end of surgery provides proven endophthalmitis prophylaxis.
- Posterior capsular opacification (PCO): Affects 10–30% of eyes at 2–5 years. YAG capsulotomy is a 5-minute outpatient laser procedure that instantly restores full EDOF benefit. Hydrophobic acrylic lenses (like OP-VIEW AS) have lower PCO rates than hydrophilic acrylic.
Sourcing EDOF IOLs:
The Indian Manufacturing Advantage
For hospitals, procurement managers, and international distributors evaluating EDOF IOL suppliers from India: the shift from imported to Indian-manufactured premium IOLs is well underway in both domestic government procurement and export markets.
Key considerations when sourcing EDOF IOLs from an Indian manufacturer:
- GMP certification: WHO GMP certification is the minimum for international regulatory dossiers. CE marking for European markets; FDA registration for US supply chain.
- Optical design documentation: Modulation transfer function (MTF) curves, through-focus visual acuity (TFVA) data, and dysphotopsia bench data should be available on request.
- Clinical data: At least one published or unpublished clinical series demonstrating visual outcomes. Ask for logMAR BCVA and UCVA data at distance, intermediate, and near.
- Regulatory dossiers: Technical file, device master record, ISO 11979 compliance, biocompatibility (ISO 10993).
- Supply chain reliability: Cleanroom manufacturing grade, batch consistency records, delivery lead times.
- Private label / OEM capability: Some Indian manufacturers, including Agaaz, offer private-label IOL supply for distributors wishing to market under their own brand in their territories.
Agaaz Ophthalmics, Ahmedabad, has been manufacturing and exporting IOLs and ophthalmic surgical products since 2003. The full IOL portfolio — PMMA (OP-LENS), hydrophilic foldable (OP-FOLD AS), hydrophobic foldable (OP-VIEW AS), and EDOF/trifocal (X-VIZ) — is available for international distributor enquiry, sample requests, and regulatory documentation.
Five Questions to Ask
Before Choosing an EDOF IOL
-
01"I drive at night regularly — will the halos from an EDOF be a problem?"Most EDOF patients drive comfortably at night after adaptation (3–6 months). The halos are less intense than trifocal. But if you're a professional night driver (truck driver, taxi driver) with very high night-vision demands, discuss this specifically with your surgeon — some choose monofocal for near-perfect night optics and use reading glasses instead.
-
02"I have dry eyes — can I still get an EDOF?"Active dry eye disease is a contraindication for EDOF IOL. The unstable tear film creates a variable corneal surface that disrupts EDOF optics, producing fluctuating vision and reduced satisfaction. Your surgeon should treat DED to clinical stability (TBUT >10 sec, minimal corneal staining, controlled symptoms) for at least 3 months before implanting any premium IOL. See our Dry Eye guide.
-
03"I also have astigmatism — does that affect my EDOF suitability?"Uncorrected astigmatism degrades EDOF outcomes significantly. If you have more than 1.0–1.5D of regular corneal astigmatism, your surgeon should consider a toric EDOF IOL — one that incorporates both EDOF optical design and astigmatic correction. Several toric EDOF options exist (Tecnis Symfony Toric, AT Lara Toric, and others). Agaaz's toric IOL portfolio covers the astigmatic correction need — ask your surgeon about toric EDOF specifically. Our IOL comparison guide covers this in detail.
-
04"What's the difference between ₹40,000 EDOF and ₹80,000 EDOF at the same hospital?"The primary difference is lens design/brand: at ₹80K you're typically getting a branded imported lens (J&J Symfony, Zeiss AT Lara) with extensive published clinical literature. At ₹40K, you may be getting a newer or Indian-manufactured EDOF with fewer peer-reviewed publications but equivalent optical bench performance. Ask your surgeon specifically what optical outcomes data they have for that specific lens at your power range — not brand marketing, but actual through-focus curves.
-
05"If I'm not happy with the EDOF result, is it reversible?"IOL exchange (removing the EDOF and replacing with a monofocal) is technically possible but involves significantly more surgical risk than primary cataract surgery — particularly after the capsular bag has contracted around the lens (typically 3+ months post-surgery). The corneal endothelium is at higher risk in an IOL exchange, and the outcome is less predictable. This is why candidate selection and pre-operative counselling are so important: the consequences of choosing the wrong IOL are not easily undone.

EDOF stands for Extended Depth of Focus. In eye surgery, it refers to a category of intraocular lens (IOL) that replaces the natural lens during cataract surgery. Unlike traditional monofocal IOLs (which focus only at one distance) or multifocal IOLs (which create 2–3 discrete focal points), an EDOF IOL creates a continuous elongated focal zone — from distance (6 metres and beyond) through intermediate (60–100 cm, covering screens, dashboards, cooking). The first FDA-approved EDOF IOL was the Johnson & Johnson Tecnis Symfony in 2016. EDOF technology has since been adopted by multiple manufacturers including Zeiss, Hoya, and Indian manufacturers like Agaaz Ophthalmics.
Not universally. EDOF produces fewer halos and starbursts than trifocal multifocal lenses, which makes it better for night driving, screen work, and patients sensitive to glare. The tradeoff is near reading vision — EDOF doesn't give spectacle-free fine near vision as reliably as trifocal. So "better" depends on the patient: for a professional driver or IT worker who primarily needs distance-intermediate, EDOF is better. For a retired person who reads extensively and doesn't drive at night, trifocal's superior near vision (at the cost of more halos) may be a better match. No single IOL type is universally superior — candidate selection matters more than the lens.
EDOF IOL prices in India in 2026 (per eye, including surgery at private hospitals): Imported brands like J&J Tecnis Symfony, Zeiss AT Lara, and Hoya range from ₹45,000–₹85,000 per eye. Indian-manufactured EDOF options, including X-VIZ by Agaaz Ophthalmics, are available at significantly lower prices through Agaaz's hospital distribution network. At government hospitals (AIIMS, RIO, government medical colleges), subsidised pricing or PMJAY coverage may reduce costs to ₹500–₹5,000 per eye. Always ask for an itemised quote: lens + surgery + OT + anaesthesia + medications + follow-up should all be included in a fair comparison.
For most daily activities, no. EDOF provides clear vision from distance through intermediate — driving, television, computers, cooking, most social activities — without glasses. Where reading glasses remain occasionally useful: very fine print (medicine packet text, nutritional labels), reading books in dim light, prolonged sustained reading. Most EDOF patients (85–90%) describe themselves as "glasses-free for most of the day" and use reading glasses occasionally rather than constantly. If your benchmark for success is never wearing glasses under any circumstances, EDOF may not meet that expectation — trifocal comes closer to full spectacle independence, at the cost of more halos.
Yes — toric versions of EDOF IOLs combine the extended depth of focus with astigmatism correction in a single lens. Standard EDOF IOLs do not correct astigmatism; if you have more than 1.0–1.5 dioptres of regular corneal astigmatism, uncorrected astigmatism will degrade EDOF outcomes. Your surgeon will measure astigmatism with corneal topography and keratometry during pre-operative assessment. If significant regular astigmatism is present, a toric EDOF is the appropriate choice. Several manufacturers offer toric EDOF variants — confirm availability and IOL power range with your surgeon.
The brain's neuroadaptation to EDOF optics typically takes 1–6 months. In the first 2–4 weeks, some patients notice halos around night lights or a slight visual "adjustment" quality. Over the following months, the brain progressively filters out these phenomena and the vision settles into the intended continuous-range clarity. Most patients report that by 3 months they no longer actively notice halos. Full adaptation is usually complete by 6–12 months. Patience during this period is important: some patients who might have been satisfied at 6 months request lens exchange at 4 weeks because they weren't counselled about the adaptation window. Surgeons and patients should commit to at least 3–6 months before evaluating final satisfaction.
With caution, and case-by-case. Mild to moderate stable glaucoma is not an absolute contraindication for EDOF IOLs. However, advanced glaucoma with significant visual field loss reduces the retina's ability to process the contrast available in EDOF designs, making patients less likely to achieve satisfying outcomes — particularly the reduced contrast sensitivity that all premium IOLs involve to varying degrees. Patients on multiple IOP-lowering medications may also have dry eye from preservative exposure, which further compromises EDOF outcomes. The general guideline: monofocal IOL for advanced glaucoma; EDOF may be discussed for mild-moderate glaucoma with healthy-functioning central macula and realistic expectations. See our Glaucoma guide for the full context.
X-VIZ is an EDOF/Trifocal intraocular lens manufactured by Agaaz Ophthalmics at their GMP-certified facility in Narol, Ahmedabad, Gujarat, India. It is designed to provide distance-to-near spectacle independence for cataract patients, using trifocal/EDOF optical technology in an Indian-manufactured lens. It is part of Agaaz's premium IOL portfolio, which includes PMMA (OP-LENS), hydrophilic foldable (OP-FOLD AS), hydrophobic foldable (OP-VIEW AS), and the X-VIZ EDOF/trifocal. Agaaz has been manufacturing ophthalmic surgical products since 2003 and exports to 15+ countries. Contact info@agaaz.life for product documentation, samples, and distribution enquiry.
Standard health insurance in India (mediclaim) typically covers cataract surgery with a monofocal IOL. The "upgrade" cost for a premium IOL — the difference between a standard monofocal and an EDOF lens — is generally not covered by insurance and must be paid out of pocket. PMJAY (Pradhan Mantri Jan Arogya Yojana) covers cataract surgery under package rates that include a standard IOL; premium lens upgrades are outside the package. Corporate health insurance policies with higher coverage limits occasionally cover premium IOLs — check your specific policy. Some hospitals offer EMI schemes for the premium lens cost. Always confirm with your insurer before surgery; policies vary considerably.
The deciding question is: which matters more to you — near reading independence OR minimising halos and night vision disturbance? If you say "I really don't want to wear reading glasses ever, including for books and phones" — trifocal is the better match, understanding you accept more halos. If you say "I drive a lot at night, work at computers all day, and I'm okay with occasional reading glasses for fine print" — EDOF is the better match. A good surgeon will ask you these questions, show you example halo images for each IOL type, and help you decide based on your actual daily visual demands. Pre-operative counselling tools (like the EDOF/multifocal preference questionnaire used at major centres) can structure this conversation. There is no universally correct answer — it depends on your lifestyle and priorities.

- Patients with realistic expectations — specifically: comfortable knowing they may occasionally use reading glasses for fine near work. Patients who understand and accept this are excellent candidates.
Poor EDOF Candidates — Choose a Different Lens
- Active dry eye disease — the tear film instability in DED creates a variable, irregular corneal surface that disrupts EDOF optics. This is contraindicated. Treat DED to stability before considering premium IOL. See our Dry Eye Disease guide.
- Keratoconus or irregular astigmatism — any corneal irregularity significantly degrades EDOF outcomes. The elongated focal zone design is highly sensitive to aberrations that an irregular cornea introduces.
- Macular disease (AMD, diabetic maculopathy) — premium IOLs of any type deliver their benefits through retinal image quality; macular disease compromises the retina's ability to resolve those images regardless of IOL design.
- Patients who depend heavily on near vision for work — jewellers, tailors, microsurgeons, dentists — whose livelihood requires sustained fine near work. Monofocal or combined monovision strategy is safer.
- Severe glaucoma — reduced contrast sensitivity from glaucoma makes patients less likely to benefit from the contrast tradeoffs in premium IOLs.
- Very high expectations of complete spectacle independence at all distances — if a patient truly insists on reading the newspaper without any glasses, trifocal is their lens (and they should be counselled on halos). EDOF will disappoint them for fine near work.
What the Procedure Looks Like:
Nothing Unusual. Same Day Home.
EDOF IOL implantation uses the same phacoemulsification technique as any other premium IOL. There is no special surgical approach for EDOF — the premium is in the optical design of the lens, not in the surgical method. Standard 2.2–2.8 mm clear corneal microincision phacoemulsification, cortical clean-up, and IOL implantation into the capsular bag using an injector.
What does matter specifically for EDOF: precise biometry. The EDOF focal range extends from distance to intermediate, but the exact placement of that range depends on accurate IOL power calculation. A 0.5D residual refractive error — acceptable with a monofocal where the patient simply updates their glasses — is clinically meaningful with an EDOF because it shifts the entire elongated focal zone. Modern optical biometry (IOLMaster 700, Lenstar, Pentacam-integrated calculations) and modern IOL formulas (Barrett Universal II, Kane, Hill-RBF) should be used. Keratometry from topography, not just manual K readings.
- Anaesthesia: Topical (eye drops) — no injection, no patches, awake throughout. Comfortable for the vast majority of patients.
- Duration: 15–25 minutes per eye at a skilled surgeon's hands. Same day discharge. No hospitalisation.
- Recovery: Vision improves within hours. Full EDOF benefit appreciated as the brain adapts — typically 1–3 months for full visual quality optimisation.
- Post-operative regimen: Antibiotic + steroid + NSAID drops for 4–6 weeks. MOXGUARD (intracameral moxifloxacin) at the end of surgery provides proven endophthalmitis prophylaxis.
- Posterior capsular opacification (PCO): Affects 10–30% of eyes at 2–5 years. YAG capsulotomy is a 5-minute outpatient laser procedure that instantly restores full EDOF benefit. Hydrophobic acrylic lenses (like OP-VIEW AS) have lower PCO rates than hydrophilic acrylic.
Sourcing EDOF IOLs:
The Indian Manufacturing Advantage
For hospitals, procurement managers, and international distributors evaluating EDOF IOL suppliers from India: the shift from imported to Indian-manufactured premium IOLs is well underway in both domestic government procurement and export markets.
Key considerations when sourcing EDOF IOLs from an Indian manufacturer:
- GMP certification: WHO GMP certification is the minimum for international regulatory dossiers. CE marking for European markets; FDA registration for US supply chain.
- Optical design documentation: Modulation transfer function (MTF) curves, through-focus visual acuity (TFVA) data, and dysphotopsia bench data should be available on request.
- Clinical data: At least one published or unpublished clinical series demonstrating visual outcomes. Ask for logMAR BCVA and UCVA data at distance, intermediate, and near.
- Regulatory dossiers: Technical file, device master record, ISO 11979 compliance, biocompatibility (ISO 10993).
- Supply chain reliability: Cleanroom manufacturing grade, batch consistency records, delivery lead times.
- Private label / OEM capability: Some Indian manufacturers, including Agaaz, offer private-label IOL supply for distributors wishing to market under their own brand in their territories.
Agaaz Ophthalmics, Ahmedabad, has been manufacturing and exporting IOLs and ophthalmic surgical products since 2003. The full IOL portfolio — PMMA (OP-LENS), hydrophilic foldable (OP-FOLD AS), hydrophobic foldable (OP-VIEW AS), and EDOF/trifocal (X-VIZ) — is available for international distributor enquiry, sample requests, and regulatory documentation.
Five Questions to Ask
Before Choosing an EDOF IOL
-
01"I drive at night regularly — will the halos from an EDOF be a problem?"Most EDOF patients drive comfortably at night after adaptation (3–6 months). The halos are less intense than trifocal. But if you're a professional night driver (truck driver, taxi driver) with very high night-vision demands, discuss this specifically with your surgeon — some choose monofocal for near-perfect night optics and use reading glasses instead.
-
02"I have dry eyes — can I still get an EDOF?"Active dry eye disease is a contraindication for EDOF IOL. The unstable tear film creates a variable corneal surface that disrupts EDOF optics, producing fluctuating vision and reduced satisfaction. Your surgeon should treat DED to clinical stability (TBUT >10 sec, minimal corneal staining, controlled symptoms) for at least 3 months before implanting any premium IOL. See our Dry Eye guide.
-
03"I also have astigmatism — does that affect my EDOF suitability?"Uncorrected astigmatism degrades EDOF outcomes significantly. If you have more than 1.0–1.5D of regular corneal astigmatism, your surgeon should consider a toric EDOF IOL — one that incorporates both EDOF optical design and astigmatic correction. Several toric EDOF options exist (Tecnis Symfony Toric, AT Lara Toric, and others). Agaaz's toric IOL portfolio covers the astigmatic correction need — ask your surgeon about toric EDOF specifically. Our IOL comparison guide covers this in detail.
-
04"What's the difference between ₹40,000 EDOF and ₹80,000 EDOF at the same hospital?"The primary difference is lens design/brand: at ₹80K you're typically getting a branded imported lens (J&J Symfony, Zeiss AT Lara) with extensive published clinical literature. At ₹40K, you may be getting a newer or Indian-manufactured EDOF with fewer peer-reviewed publications but equivalent optical bench performance. Ask your surgeon specifically what optical outcomes data they have for that specific lens at your power range — not brand marketing, but actual through-focus curves.
-
05"If I'm not happy with the EDOF result, is it reversible?"IOL exchange (removing the EDOF and replacing with a monofocal) is technically possible but involves significantly more surgical risk than primary cataract surgery — particularly after the capsular bag has contracted around the lens (typically 3+ months post-surgery). The corneal endothelium is at higher risk in an IOL exchange, and the outcome is less predictable. This is why candidate selection and pre-operative counselling are so important: the consequences of choosing the wrong IOL are not easily undone.

EDOF stands for Extended Depth of Focus. In eye surgery, it refers to a category of intraocular lens (IOL) that replaces the natural lens during cataract surgery. Unlike traditional monofocal IOLs (which focus only at one distance) or multifocal IOLs (which create 2–3 discrete focal points), an EDOF IOL creates a continuous elongated focal zone — from distance (6 metres and beyond) through intermediate (60–100 cm, covering screens, dashboards, cooking). The first FDA-approved EDOF IOL was the Johnson & Johnson Tecnis Symfony in 2016. EDOF technology has since been adopted by multiple manufacturers including Zeiss, Hoya, and Indian manufacturers like Agaaz Ophthalmics.
Not universally. EDOF produces fewer halos and starbursts than trifocal multifocal lenses, which makes it better for night driving, screen work, and patients sensitive to glare. The tradeoff is near reading vision — EDOF doesn't give spectacle-free fine near vision as reliably as trifocal. So "better" depends on the patient: for a professional driver or IT worker who primarily needs distance-intermediate, EDOF is better. For a retired person who reads extensively and doesn't drive at night, trifocal's superior near vision (at the cost of more halos) may be a better match. No single IOL type is universally superior — candidate selection matters more than the lens.
EDOF IOL prices in India in 2026 (per eye, including surgery at private hospitals): Imported brands like J&J Tecnis Symfony, Zeiss AT Lara, and Hoya range from ₹45,000–₹85,000 per eye. Indian-manufactured EDOF options, including X-VIZ by Agaaz Ophthalmics, are available at significantly lower prices through Agaaz's hospital distribution network. At government hospitals (AIIMS, RIO, government medical colleges), subsidised pricing or PMJAY coverage may reduce costs to ₹500–₹5,000 per eye. Always ask for an itemised quote: lens + surgery + OT + anaesthesia + medications + follow-up should all be included in a fair comparison.
For most daily activities, no. EDOF provides clear vision from distance through intermediate — driving, television, computers, cooking, most social activities — without glasses. Where reading glasses remain occasionally useful: very fine print (medicine packet text, nutritional labels), reading books in dim light, prolonged sustained reading. Most EDOF patients (85–90%) describe themselves as "glasses-free for most of the day" and use reading glasses occasionally rather than constantly. If your benchmark for success is never wearing glasses under any circumstances, EDOF may not meet that expectation — trifocal comes closer to full spectacle independence, at the cost of more halos.
Yes — toric versions of EDOF IOLs combine the extended depth of focus with astigmatism correction in a single lens. Standard EDOF IOLs do not correct astigmatism; if you have more than 1.0–1.5 dioptres of regular corneal astigmatism, uncorrected astigmatism will degrade EDOF outcomes. Your surgeon will measure astigmatism with corneal topography and keratometry during pre-operative assessment. If significant regular astigmatism is present, a toric EDOF is the appropriate choice. Several manufacturers offer toric EDOF variants — confirm availability and IOL power range with your surgeon.
The brain's neuroadaptation to EDOF optics typically takes 1–6 months. In the first 2–4 weeks, some patients notice halos around night lights or a slight visual "adjustment" quality. Over the following months, the brain progressively filters out these phenomena and the vision settles into the intended continuous-range clarity. Most patients report that by 3 months they no longer actively notice halos. Full adaptation is usually complete by 6–12 months. Patience during this period is important: some patients who might have been satisfied at 6 months request lens exchange at 4 weeks because they weren't counselled about the adaptation window. Surgeons and patients should commit to at least 3–6 months before evaluating final satisfaction.
With caution, and case-by-case. Mild to moderate stable glaucoma is not an absolute contraindication for EDOF IOLs. However, advanced glaucoma with significant visual field loss reduces the retina's ability to process the contrast available in EDOF designs, making patients less likely to achieve satisfying outcomes — particularly the reduced contrast sensitivity that all premium IOLs involve to varying degrees. Patients on multiple IOP-lowering medications may also have dry eye from preservative exposure, which further compromises EDOF outcomes. The general guideline: monofocal IOL for advanced glaucoma; EDOF may be discussed for mild-moderate glaucoma with healthy-functioning central macula and realistic expectations. See our Glaucoma guide for the full context.

It is designed to provide distance-to-near spectacle independence for cataract patients, using trifocal/EDOF optical technology in an Indian-manufactured lens. It is part of Agaaz's premium IOL portfolio, which includes PMMA (OP-LENS), hydrophilic foldable (OP-FOLD AS), hydrophobic foldable (OP-VIEW AS), and the X-VIZ EDOF/trifocal. Agaaz has been manufacturing ophthalmic surgical products since 2003 and exports to 15+ countries. Contact info@agaaz.life for product documentation, samples, and distribution enquiry.
Standard health insurance in India (mediclaim) typically covers cataract surgery with a monofocal IOL. The "upgrade" cost for a premium IOL — the difference between a standard monofocal and an EDOF lens — is generally not covered by insurance and must be paid out of pocket. PMJAY (Pradhan Mantri Jan Arogya Yojana) covers cataract surgery under package rates that include a standard IOL; premium lens upgrades are outside the package. Corporate health insurance policies with higher coverage limits occasionally cover premium IOLs — check your specific policy. Some hospitals offer EMI schemes for the premium lens cost. Always confirm with your insurer before surgery; policies vary considerably.
The deciding question is: which matters more to you — near reading independence OR minimising halos and night vision disturbance? If you say "I really don't want to wear reading glasses ever, including for books and phones" — trifocal is the better match, understanding you accept more halos. If you say "I drive a lot at night, work at computers all day, and I'm okay with occasional reading glasses for fine print" — EDOF is the better match. A good surgeon will ask you these questions, show you example halo images for each IOL type, and help you decide based on your actual daily visual demands. Pre-operative counselling tools (like the EDOF/multifocal preference questionnaire used at major centres) can structure this conversation. There is no universally correct answer — it depends on your lifestyle and priorities.
