What Eye Drops to Use After Cataract Surgery | Drops Decoded

A typical regimen pairs an antibiotic, a steroid, and an NSAID, but the exact drugs, frequency, and taper come from your surgeon’s written plan.

Three bottles, three jobs, three schedules, and a printed sheet naming which eye gets which drop. Most people read that sheet in the car, then stall on day four when one bottle runs low and the label is a blur.

The standard answer to what eye drops to use after cataract surgery has not moved in years: an antibiotic, a steroid, and an NSAID, each covering a separate risk. Your surgeon’s sheet outranks this page, because drug choice, strength, frequency, and taper length all shift with the procedure and with how your eye responds.

Eye Drops After Cataract Surgery: What Each Type Does

Three drug classes cover nearly every routine case, each aimed at a different complication.

The antibiotic guards against infection, usually a fourth-generation fluoroquinolone such as moxifloxacin or gatifloxacin. Most surgeons start it the day of surgery or the next morning and stop it after one to two weeks.

The steroid controls inflammation. Prednisolone acetate 1% is the workhorse; difluprednate 0.05%, loteprednol etabonate 0.5%, and rimexolone 1% are common alternatives. It goes in several times daily at first, then tapers. The American Academy of Ophthalmology’s review of postoperative drops walks through each class and the evidence behind the schedules.

The NSAID lowers the odds of cystoid macular edema, a swelling that can blur vision weeks after a surgery that seemed to go perfectly. Bromfenac 0.09% goes in twice daily, nepafenac 0.1% three times daily, ketorolac four times daily.

Preservative-free artificial tears soothe dryness and grittiness between doses but never replace the other three. If you want to stock up on lubricants, our tested picks for post-surgery eye drops covers which ones are worth buying. Run any addition past the surgeon while multiple drops are in play.

Diabetes, glaucoma, a previous steroid response, corneal disease, and complicated surgery can all rewrite that list. A regimen borrowed from a friend says nothing about yours.

How Long Do You Stay On The Drops?

A routine course runs about four weeks, with the steroid stretching two to six weeks as it tapers down. The antibiotic usually finishes first, often within one to two weeks.

Tapering means cutting the number of daily drops, not quitting early. Never extend a steroid past its prescribed end date or stop it on your own; ophthalmic steroids need supervision, and unsupervised use brings genuine complications. Guy’s and St Thomas’ NHS Foundation Trust publishes a week-by-week sample schedule on its after-cataract-surgery page, which shows the shape of a taper without describing your prescription.

Some surgeons now skip the bottles with a dropless approach: antibiotic injected into the eye at the end of surgery, a steroid injection, or a drug-eluting insert. That call belongs to the operating surgeon. If you were handed a schedule, follow it even when a friend had the dropless version.

Putting Them In Without Contaminating The Bottle

Wash up, pull the lower lid into a pocket, and let one drop fall onto the eye without the nozzle touching anything. Close the eye, blink gently, dab the overflow, cap the bottle.

1. Wash and dry your hands.
2. Read the label: correct drug, correct eye.
3. Tilt your head back or lie down and look up.
4. Pull the lower eyelid down to form a pocket.
5. Squeeze one drop in, keeping the tip clear of the eye, lid, and lashes.
6. Close the eye, blink, blot with a clean tissue, then cap the bottle.

Space different medications three to five minutes apart, the gap one NHS post-operative leaflet specifies, so the second drop does not wash the first away. Keep a separate bottle for each eye during the first month when your team advises it, and discard opened bottles on their timeline; some protocols call for tossing them four weeks after opening. When a bottle empties before the course ends, get a refill rather than stopping early. Never swap in a different strength, a combination product, or a leftover bottle without approval, and keep glaucoma drops going unless the surgeon says otherwise.

The routine is going right when the drop lands, nothing touches the tip, and the bottle is back in the box inside a minute.

What Should Make You Call The Surgeon?

Rising pain, worsening redness, fading vision, strong light sensitivity, or new discharge all warrant a same-day call rather than a wait for the next visit.

Topical NSAIDs can cause keratopathy and, rarely, corneal ulceration or corneal melt, so those symptoms are not something to ride out over a weekend.

• Pain that gets worse instead of better
• Redness or light sensitivity that keeps climbing
• Vision that drops after it had improved
• New discharge from the eye
• A dropper tip that touched your eye or lashes

Keep the printed schedule beside the bottles, set phone alarms for the taper days, and call the office rather than guessing.
