The range is genuinely enormous. Someone in rural India can get cataract surgery for $150 at a government camp. Someone in New York pays $6,000 per eye at a private clinic. And both might leave with the same lens, the same surgical technique, and comparable vision outcomes.

So what explains the gap? And if you're trying to figure out what to pay — or what to charge — where do you even start?

This guide breaks down actual costs across more than 20 countries, explains what's driving the differences, and includes a calculator you can use to estimate what surgery should cost in your specific situation.

The Cost by Country — What You're Actually Paying

Here's something most hospital websites don't tell you: the price you see quoted usually excludes several things. Pre-operative tests. Anaesthesia. Post-op medications. Follow-up visits. And — often — the cost of the lens upgrade if you want anything better than the most basic option.

The numbers below are total out-of-pocket estimates for standard monofocal IOL surgery, per eye, private sector unless noted.

The Lens Is the Biggest Variable

This is the part most people don't know going in. The surgery itself — the phacoemulsification, the surgeon's time, the operating theatre — that's a relatively fixed cost in any given market. What moves the price dramatically is the lens going into your eye.

There are three categories. The price differences at the patient level are enormous.

Approximate total cost per eye, private sector, India/Middle East/UK range. US costs are 2–3× higher.

A PMMA lens costs a surgical facility somewhere between $2 and $10. A hydrophilic foldable, $15–$40. A trifocal premium IOL, $200–$600. Those wholesale costs get marked up 5–10× by the time they reach patients in high-income countries. In India, the markup is smaller — which is part of why Indian costs are so much lower.

The three lens types — what you're actually choosing between

• PMMA (rigid): The original IOL material from the 1950s. Requires a 5–6mm incision. Excellent for high-volume, cost-sensitive settings. Vision outcome is equivalent to foldable at 1 year. Used extensively in Indian government hospitals and rural camp programs. Agaaz manufactures the OP-LENS.
• Foldable (hydrophilic or hydrophobic acrylic): Rolled into a cartridge and delivered through a 2.5mm micro-incision. Faster healing, less astigmatism. Significantly lower posterior capsule opacification (PCO) risk with hydrophobic designs. Standard in private hospitals globally. Agaaz's OP-FOLD AS and OP-VIEW AS.
• Premium (EDOF, trifocal, toric): Engineered to give good vision at multiple distances — reducing or eliminating the need for reading glasses. The vision promise is real, but so is the price: $3,500–$8,000 per eye in private markets. Suitable for patients with specific visual goals and realistic expectations. Agaaz's X-VIZ EDOF platform.

What's Included in the Price — and What Usually Isn't

This varies enormously by country and facility, but here's a general pattern.

Does Insurance Cover Cataract Surgery?

In most countries, yes — for standard surgery with a basic monofocal lens. The nuance is what "covered" actually means.

• UK NHS: Standard cataract surgery with a monofocal IOL is free. Waiting times vary by region — typically 3–18 months in 2026. Premium lenses are not available on the NHS.
• USA — Medicare: Covers cataract surgery and a standard IOL. Premium lens upgrades (toric, multifocal, EDOF) are not covered — patients pay the lens upgrade cost out of pocket, which can be $1,500–3,000 per eye.
• India — Ayushman Bharat (PM-JAY): Covers cataract surgery for eligible low-income patients. PMMA IOL included. Private hospitals empanelled under the scheme charge the government; patient pays nothing.
• UAE: Private insurance typically covers standard cataract surgery. Coverage depends heavily on the policy tier — check explicitly whether the IOL type matters.
• Nigeria — NHIS: Technically covers ophthalmic care, but implementation is inconsistent. Many patients end up paying partially or fully out of pocket even with NHIS registration.
• Germany — GKV (statutory insurance): Covers standard surgery and a basic IOL. Premium IOLs require patient co-payment (typically €800–1,500 per eye for toric or multifocal).

Six Questions to Ask Before You Book

Most people don't know what to ask. Here are the six that actually matter.

1. 01
   Is this price per eye or for both?

   Sounds obvious. It isn't. Clinics in India and the Middle East usually quote per eye; UK and Australia sometimes quote per procedure. Always clarify.

2. 02
   What IOL brand and type is included?

   Ask specifically: "What lens are you planning to use, and is it PMMA, hydrophilic, or hydrophobic acrylic?" A clinic that can't answer this clearly is a clinic to be cautious about. The IOL brand and type directly affects your PCO risk over the next 5–10 years.

3. 03
   Are pre-operative tests included?

   Biometry (measuring your eye for the correct IOL power) and keratometry are essential. Some clinics do them in-house and include the cost; others refer you out and charge separately. Budget ₹2,000–8,000 in India, £100–400 in the UK.

4. 04
   What happens if there's a complication?

   Rare, but worth asking. Does the clinic cover re-intervention at no cost? Do they have a vitreoretinal surgeon on call if something goes wrong intraoperatively? The answer tells you a lot about the facility.

5. 05
   How many of these operations has your surgeon done?

   Phacoemulsification has a well-documented learning curve. Experienced surgeons — typically 1,000+ cases — have significantly lower complication rates. Don't be embarrassed to ask.

6. 06
   Is follow-up care included, and for how long?

   The first day-after check and week-one check are standard. What about 6 weeks? 3 months? If vision doesn't settle correctly, you want to know who's responsible for sorting it — and whether that's included in what you paid.

Is Medical Tourism Worth It for Cataract Surgery?

For patients from the US, UK, and Australia, India and Thailand offer the same surgical technique and comparable IOL options at 60–80% lower cost. The maths is compelling.

A patient in New York paying $6,000 per eye ($12,000 for both) could fly to a top-tier Indian hospital like Sankara or LV Prasad, pay ₹50,000–80,000 per eye ($600–$960), spend a week recovering, and return home having spent perhaps $4,000 total — including flights and accommodation. And the surgeons at those facilities do more cataract operations in a month than many US surgeons do in a year.

That said, there are real downsides:

• Follow-up: Post-op care happens at home, with a different doctor who didn't do the surgery. If there's a complication — rare, but possible — this gets complicated.
• Flight pressure changes: Flying within 24–48 hours of surgery raises questions about IOP fluctuation, though evidence on clinical significance is mixed.
• Accountability: If something goes wrong, legal recourse across borders is difficult.

The sensible approach for medical tourism: go to a facility with a clear track record, choose a surgeon whose credentials you've independently verified, stay in-country for at least 5–7 days post-op, and ensure your home ophthalmologist is briefed in advance to handle any follow-up.

The Short Version

• Standard cataract surgery ranges from under $200 (India, government) to $7,000+ (USA, premium private).
• The lens type — not the surgery itself — drives most of the price variation. PMMA is cheapest; trifocal IOLs are most expensive.
• Insurance covers standard surgery in most countries. Premium lenses almost always cost extra, regardless of coverage.
• Medical tourism to India or Thailand can cut costs by 70–80% for patients from the US, UK, and Australia — with real trade-offs in follow-up logistics.
• Before booking: get an itemised quote, confirm the IOL brand and type, and ask what's included in follow-up care.
• Visual outcomes at 1 year are statistically equivalent between PMMA and foldable IOLs. Price does not reliably predict vision quality.
