Yellox (bromfenac 0.9 mg/mL) is an MHRA-licensed non-steroidal anti-inflammatory (NSAID) eye drop used after cataract surgery. Applied as one drop twice a day for around two weeks, it reduces post-operative inflammation and lowers the risk of cystoid macular oedema (CMO) — the swelling at the macula that is the commonest cause of blurred vision after surgery. Yellox is normally part of the all-inclusive aftercare with private cataract surgery, so most patients pay nothing extra; bought separately on private prescription it costs from around £15 per bottle.
What is Yellox (bromfenac)?
After cataract surgery the eye mounts a natural inflammatory response to healing. Left unchecked, that inflammation can cause discomfort, redness and — importantly — fluid build-up at the macula. Yellox contains bromfenac, an NSAID that blocks the enzymes (cyclo-oxygenase) driving this inflammation.
NSAID drops like Yellox work differently from steroid drops, and the two are often prescribed together because they tackle inflammation by complementary routes. The combination is well established for keeping the eye comfortable and protecting central vision in the weeks after surgery. It is a routine, well-tolerated part of modern cataract aftercare.
How Yellox is used after cataract surgery
- Start as directed — typically the day after surgery, or as your surgeon instructs.
- Instil one drop into the operated eye twice a day, morning and evening.
- If you also use steroid or antibiotic drops, leave a few minutes between each so they aren't washed out.
- Continue for the full course (usually around two weeks) even if the eye already feels comfortable.
- Wash your hands first and avoid touching the dropper tip to the eye or lashes.

Book a cataract assessmentDrops vs dropless cataract surgery
A short course of eye drops after cataract surgery is standard and very effective. For patients who find a drop regime difficult — for example due to arthritis or memory — a dropless approach is an alternative, where anti-inflammatory medication is delivered during the operation itself.
Yellox in your recovery
Day 1 onwards
Begin Yellox as instructed, one drop twice daily in the operated eye, alongside any steroid and antibiotic drops.
Week 1
Continue the full drop schedule. At your first review your surgeon checks that the eye is settling and the macula is healthy.
Around 2 weeks
The Yellox course typically finishes here, though your surgeon may adjust the length based on your healing.
Week 4
A final review confirms healing and any new glasses prescription. Report any drop in vision or increasing discomfort promptly.
