Key takeaways
- After cataract surgery you use antibiotic and anti-inflammatory eye drops for about 2 to 4 weeks on a tapering schedule that reduces the daily number over time.
- The drops prevent infection and settle inflammation, and finishing the full course matters even once the eye feels comfortable.
- A clear plastic shield is worn at night for about a week so you cannot rub the eye in your sleep.
- Wash your hands before drops, do not let the bottle tip touch the eye, and leave a few minutes between different drops.
- Avoid rubbing the eye, swimming, and dusty or dirty places in the first weeks; contact your eye team if pain, redness or vision suddenly worsen.
After cataract surgery you use antibiotic and anti-inflammatory eye drops for about 2 to 4 weeks on a tapering schedule that gradually reduces the daily number, wear a clear shield at night for about a week so you cannot rub the eye in your sleep, and keep up simple hygiene to protect the healing eye1. The drops prevent infection and settle inflammation, and finishing the full course matters even once the eye feels comfortable2.
This is the practical aftercare guide, checked by a consultant ophthalmic surgeon. For the full timeline it sits within, see cataract surgery recovery, and for the operation that comes first, cataract surgery.
The drops and the tapering schedule
After surgery you use antibiotic and anti-inflammatory eye drops for about 2 to 4 weeks on a tapering schedule, where the number of daily drops reduces over time1. The antibiotic course is often shorter than the anti-inflammatory one, and the exact regimen varies between surgeons, so the written schedule you are given is the one to follow.
The drops do two jobs: the antibiotic prevents infection and the anti-inflammatory settles inflammation2. Finishing the full course matters even once the eye feels fine. When I had my second eye done a few weeks after the first, the two tapers overlapped and I genuinely could not have kept them straight without a written chart, which I will come back to.
How to put the drops in safely
To put drops in, wash your hands, tilt your head back, gently pull the lower lid down to make a small pocket, and let one drop fall in without letting the bottle tip touch the eye or lashes3. Close the eye gently for a minute afterwards.
If you use more than one type of drop, leave a few minutes between them so one does not wash the other out3. If a drop misses, it is fine to repeat. My hands were unsteady at first, so I lay down on the bed to do mine, which made it far easier to drop them in without poking the eye, and the shake settled within a few days.
The night shield and hygiene
A clear plastic shield is worn at night for about a week so you cannot rub or press the eye in your sleep, when you have no control over your hands1. You tape it over the eye before bed; you do not normally need it during the day.
For hygiene, wash your hands before going near the eye, keep the bottle tip clean, avoid eye make-up for a couple of weeks, and gently clean any sticky lashes with cooled boiled water if advised3. I taped my shield on each night for the first week after both operations, and on the nights I almost forgot, the thought of rubbing a fresh wound in my sleep was enough to send me back upstairs for it.
What to avoid and when to call
In the first weeks, avoid rubbing the eye, swimming, and dusty or dirty environments, while gentle normal activity is fine4. Keep a written tick chart of your drops, as the tapering schedule is genuinely easy to lose track of, especially with two eyes overlapping.
Contact your eye team promptly if you notice warning signs:
- Increasing pain that the drops do not settle.
- Redness or discharge that is getting worse.
- Suddenly worsening vision.
- New floaters or flashing lights, or a shadow across the vision.
These are uncommon, but early contact matters. For the broader list of what can go wrong and how rare it is, see cataract surgery risks and complications, and for looking after your eyes once healed, looking after your eyes after cataract surgery.

Common questions
How long do I use eye drops after cataract surgery?
Antibiotic and anti-inflammatory drops are typically used for about 2 to 4 weeks on a tapering schedule, meaning the number of daily drops reduces over time. The exact regimen varies between surgeons, so follow the written schedule you are given. The antibiotic course is often shorter than the anti-inflammatory one, and finishing the full course matters even once the eye feels comfortable.
How do I put in eye drops after cataract surgery?
Wash your hands first, tilt your head back or lie down, gently pull the lower lid down to make a small pocket, and let one drop fall into it without touching the bottle tip to the eye or lashes. Close the eye gently for a minute. If you use more than one type of drop, leave a few minutes between them so they are not washed out. If a drop misses, it is fine to repeat.
Why do I wear a shield at night after cataract surgery?
A clear plastic shield is worn at night for about a week so you cannot rub or press on the eye in your sleep, when you have no control over your hands. Rubbing a freshly operated eye risks disturbing the healing wound or introducing infection. Tape it over the eye before bed; during the day you do not normally need it unless your surgeon advises otherwise.
What hygiene should I follow after cataract surgery?
Wash your hands before touching near the eye or putting in drops, keep the bottle tip clean and away from the eye and lashes, and avoid eye make-up for a couple of weeks. Do not rub the eye, avoid swimming and dusty or dirty environments, and gently clean any sticky lashes with cooled boiled water and a clean tissue if advised. These simple steps reduce the small risk of infection.
What if I miss a dose of eye drops?
If you miss a dose, put it in as soon as you remember and then carry on with your normal schedule; do not double up to catch up. The drops work as a course, so consistency matters more than perfect timing. If you are unsure, keep a written tick chart so you can see what you have taken, and ask your eye team if you have lost track of where you are in the taper.
Can I use my old eye drops or someone else's after surgery?
No. Use only the drops prescribed for you for this surgery, in the schedule given. Old bottles, leftover drops or someone else's medication may be the wrong type, out of date or contaminated, all of which risk a healing eye. If you run low before the course is finished, contact your eye team rather than substituting another product.
When can I stop worrying about the eye after cataract surgery?
Once you have finished the drop course and the eye has settled, usually over about 4 to 6 weeks, normal eye care resumes. Through the first weeks, keep up the drops, wear the night shield as advised, and watch for warning signs: increasing pain, redness, discharge, or suddenly worsening vision, new floaters or flashing lights, all of which mean you should contact your eye team promptly.
