Cataract Surgery · Uveitis
Cataract surgery
in uveitis:
calm the eye first,
then operate.
Uveitis and cataract often arrive together: the inflammation damages the lens and the steroids that control it clear the way for a cloud. Surgery can restore sight, but an inflamed eye heals differently. This is why surgeons plan these operations around the inflammation, not just the lens.

Section 01 — The Problem
Two diseases,
one pathway.
Uveitis is inflammation of the middle layer of the eye, the iris, ciliary body and choroid. Cataract is clouding of the lens. In uveitis the two are tightly linked: chronic inflammation changes the chemistry around the lens, and the corticosteroids that keep uveitis in check are a recognised cause of cataract, typically a patch of cloudiness at the back of the lens known as a posterior subcapsular cataract.
The result is that cataract is one of the commonest reasons for lost vision in people with long-standing uveitis, and it often appears at an age when cataract is not expected. If you are new to the condition itself, start with our uveitis guide; this page is about what changes when the eye needs an operation.
Cataract surgery in uveitis can be very successful, but it is planned around the inflammation. Surgeons try to get the eye quiet first, add anti-inflammatory cover around the operation, and prepare for scarring between the iris and lens (posterior synechiae), a small stiff pupil and a fragile capsule. Macular swelling, raised eye pressure and a clouded capsule are the main complications to anticipate. Hydrophobic acrylic lenses are commonly preferred and multifocal lenses usually avoided. Close follow-up matters because a flare after surgery can look like a routine reaction.
Section 02 — Interactive
Look at the iris
through the surgeon’s eyes.
Step through the pupil states a surgeon may meet, from a normal pupil to one stuck to the lens and then widened for surgery. Switch on active inflammation to see the cells that drift in the front of the eye and the redder iris that goes with it.
The point of the model is the sequence. A quiet eye with a normal pupil is the easy case. Add inflammation and adhesions and the working space for the surgeon shrinks, which is why releasing the adhesions and widening the pupil safely is often the first technical step of the operation.
Section 03 — The Planning Points
What surgeons
do differently.
Each item is an adjustment to routine practice. None of it is exotic, but together it makes these cases more demanding than an average cataract.
| Issue | Why it arises in uveitis | Usual response |
|---|---|---|
| Active inflammation | Operating on an inflamed eye raises the chance of a flare, macular swelling and scarring. | Aim for a quiet eye first, often for a few months, on the lowest effective treatment. Dense cataract that hides the retina may justify earlier surgery with extra cover. |
| Peri-operative steroid cover | Surgery can reawaken inflammation, so protection is built in. | Oral, periocular or intravitreal steroid and stronger drops, planned with the uveitis specialist. Antiviral cover is considered in herpetic disease. |
| Posterior synechiae and small pupil | Adhesions between the iris edge and the lens, plus a stiff iris, restrict access. | Viscoelastic dissection of adhesions, then pupil expansion with iris hooks, a ring or careful stretching. See cohesive vs dispersive OVDs. |
| Capsule and zonules | Fibrosed capsule and, in some diseases, weak zonules make the capsule opening and bag harder to manage. | Capsule staining to see the edge (trypan blue), and support devices if needed (capsular tension rings). |
| Macular oedema | Surgery in an inflamed eye is a recognised trigger for fluid in the macula. | Anti-inflammatory cover, OCT scanning when vision lags, and prompt treatment. See cystoid macular oedema after cataract surgery. |
| Eye pressure | Uveitis itself, and steroid treatment, can raise eye pressure; some patients already have glaucoma. | Pressure monitoring and, where needed, treatment before or after surgery. |
| Lens implant | Material and design affect how an inflamed eye tolerates the implant. | Often a hydrophobic acrylic lens in the bag; multifocal lenses usually avoided. See the section below. |
Section 04 — The Evidence
What the studies
say about outcomes and risk.
The direction of the findings is consistent; the exact percentages differ by uveitis type, era and technique, so this guide does not quote them.
Foster and colleagues’ early series showed that cataract surgery with lens implantation could be done in selected patients with uveitis, helping to move practice away from leaving these eyes without an implant. Bélair and colleagues used OCT to compare macular swelling after cataract surgery in eyes with and without uveitis and found that uveitic eyes were more prone to it, which is why anti-inflammatory cover and macular scanning are routine. The Standardization of Uveitis Nomenclature working group (Jabs and colleagues) defined what “inactive” and “remission” mean, which underpins the common practice of operating after a period of calm. Differences between disease types are well described in the broader literature and in the EyeWiki and StatPearls entries listed below.
Section 05 — The Lens and the Tools
Choosing the implant,
and what supports the surgeon.
Two decisions sit on top of the inflammation plan: which lens, and which supporting materials make the difficult steps safer.
Agaaz makes nothing designed specifically for uveitis, and no product here treats inflammation or lowers the risk of a flare. The connection is to the general surgical steps these eyes lean on. Ophthalmic viscoelastic devices (Agaaz supplies PURE-HYAL, OP-VISC and PURE-VISC) are used to protect the corneal endothelium and to separate iris adhesions, and the choice between cohesive and dispersive behaviour belongs to the surgeon, see the OVD overview. OP-BLUE (trypan blue) stains the anterior capsule when the red reflex is poor or the capsule is fibrosed. Product details and availability by market are provided on request.
If eye pressure is part of your picture, see also pseudoexfoliation and cataract surgery for another condition where pressure and a fragile capsule meet.
Section 06 — Before and After
What to ask
and what to watch for.
| Ask or check | Why it helps |
|---|---|
| Is the uveitis quiet, and for how long? | Surgery timing is the biggest controllable factor. |
| What steroid or other cover is planned? | Shows the surgeon and uveitis specialist are working from one plan. |
| Has the macula been scanned (OCT)? | Sets a baseline and expectations, and makes later swelling easier to spot. |
| Is the eye pressure normal on treatment? | Steroid response and uveitic glaucoma change the plan. |
| What lens is proposed and why? | A reasoned choice of material and design suited to your disease is a good sign. |
| What is the follow-up schedule? | Early and frequent review is standard in uveitic eyes. |
A person in their late thirties has had recurrent uveitis for years and has taken steroid drops almost continuously. Their vision is now hazy and glare is worse. Their uveitis specialist confirms the inflammation has been quiet for several months, then the surgeon scans the macula, notes adhesions at the pupil edge and plans a viscoelastic release and pupil expansion. A short course of extra steroid is arranged around the operation, a hydrophobic acrylic lens is placed in the bag, and they are seen within a day and again within a week. Weeks later, slightly blurred vision is scanned and treated early.
Section 07 — FAQ
Frequently asked questions
about cataract surgery in uveitis.
Two things push in the same direction. Long-standing inflammation inside the eye is itself harmful to the lens, and the corticosteroids used to control uveitis, whether drops, tablets or injections, are a well-known cause of cataract, typically a cloudiness at the back of the lens (posterior subcapsular). Many people with uveitis are also younger than the usual cataract age, so a cataract in a 30- or 40-year-old with uveitis is not unusual.
Surgery is itself an inflammatory event. Operating on an eye that is already inflamed makes a flare-up, fluid in the macula and scarring more likely, and it makes the result harder to predict. Surgeons therefore usually try to have the eye quiet first, often for a period of a few months, using the lowest treatment that holds the inflammation still. The exact interval depends on the type of uveitis and the surgeon. If the cataract is so dense that the retina cannot be seen, or is itself driving the inflammation, surgery may go ahead sooner with extra cover.
Most surgeons add anti-inflammatory cover before and after surgery. Depending on the disease this may be a short course of oral steroid, a steroid injection around or inside the eye, or stronger or longer steroid drops, and sometimes an adjustment of existing immune-suppressing treatment. If the uveitis is caused by a herpes-family virus, antiviral cover is often considered too. The plan is individual and set by the surgeon together with the uveitis specialist, so never change your own medication.
In most people with uveitis a lens implant (IOL) is placed during cataract surgery, particularly when the inflammation is well controlled and the type of uveitis is one that tolerates implants. Some forms, notably in young children with juvenile arthritis-related uveitis or in very active or recurrent disease, call for more caution, and a few surgeons choose to leave the eye without an implant at first. This is a decision for a specialist who knows your disease.
Many surgeons prefer a hydrophobic acrylic lens placed in the capsular bag, because this material is generally regarded as having good compatibility with inflamed eyes. Multifocal lenses are usually avoided because contrast loss, a hazy capsule and macular problems are all more likely in uveitis. The choice is a surgeon's judgement, not a universal rule, and is discussed further in the material-choice guide on this site.
Often it is very good, and many people regain useful sight, but the outcome is less predictable. The final vision depends on the health of the macula and optic nerve, on how well the inflammation stays controlled and on complications such as macular swelling, raised eye pressure or a clouded capsule. Some types, for example Fuchs uveitis syndrome, are generally reported to do particularly well, while others, such as juvenile arthritis-related uveitis, carry more risk. Your surgeon can explain the pattern for your disease.
Report the same day: increasing redness, pain, light sensitivity, a sudden drop in vision, or new floaters or flashes. In an eye with uveitis a flare of inflammation can look like a routine post-operative reaction, so a low threshold to call is sensible. Blurred vision some weeks after an apparently good result can be macular swelling, which is treatable; do not wait for the next scheduled visit.
