Eye drops are a routine part of cataract surgery, and most people are prescribed two or three bottles, along with a schedule telling them when to use each one. For the first few days, keeping track of which drop is due, and how long to wait before the next one, can feel like a job of its own.
Most people want to know what each drop does, how long to keep using them and what to do if they miss a dose. Each drop has its own job in protecting the eye after an operation for cataract, mainly preventing infection and controlling the swelling and redness that follow surgery.
In this article, we will cover which drops you are likely to be given, how long to use them, how to put them in, their side effects, whether you can add dry eye drops and whether eye drops can dissolve cataracts.
What Are the Three Eye Drops Used After Cataract Surgery?
The three eye drops used after cataract surgery are usually an antibiotic, a steroid and a nonsteroidal anti-inflammatory drop.
Cataract surgery replaces the cloudy natural lens of the eye with a clear artificial one, and these drops protect the eye in different ways while the small incisions heal:
- Antibiotic drops – these, such as moxifloxacin or ofloxacin, lower the risk of an eye infection in the first days after surgery.
- Steroid drops – these, such as prednisolone acetate, control inflammation, the swelling and redness inside the eye that can blur vision while it heals.
- Nonsteroidal drops – these, such as ketorolac, bromfenac or nepafenac, also reduce inflammation and pain, and they can lower the risk of fluid collecting in the macula, the center of the retina (the light-sensitive layer at the back of the eye).
Another option is a single combined drop, often called a 3-in-1 drop, which contains all three medicines in one bottle. In some cases, medicine is placed inside the eye during the operation, which can mean fewer drops afterward.
The drops you are prescribed can vary depending on your surgeon, the health of your eye and any other conditions you have. Always use them exactly as your surgeon prescribes.
How Long Do You Use Eye Drops After Cataract Surgery?

Eye drops are often prescribed for three to four weeks after cataract surgery, but the exact drops, doses and length of treatment vary depending on your surgeon, the medicine and how your eye heals.
Some surgeons also ask you to start one or two drops one to three days before the operation, so the medicine is already working on the day itself.
The chart below is only an example, and your own schedule may be different. An eye drop chart for cataract surgery might look like this:
- Antibiotic – often up to four times a day, for about one week.
- Steroid – often four times a day at first, then less often, for three to four weeks.
- Nonsteroidal – one to four times a day, depending on the drop, for two to four weeks or longer.
Steroid drops are usually reduced step by step over several weeks, a process called tapering, because stopping them suddenly can allow the inflammation to return. Your surgeon may also adjust the schedule at your follow-up visits, depending on how your eye is healing, so always follow the schedule your surgeon gives you, and check with them before you stop or change any drop.
How Do You Put In Eye Drops After Cataract Surgery?
To put in eye drops, tilt your head back, gently pull down your lower eyelid to make a small pocket, and let one drop fall into it without the bottle touching your eye.
A few habits help more of each drop stay in the eye and keep the eye clean while it heals:
- Wash your hands – clean hands lower the chance of carrying germs into the eye.
- Shake the bottle – some steroid drops, such as prednisolone acetate, are a suspension (a liquid with the medicine mixed through it), so the medicine sinks to the bottom unless you shake it first.
- Avoid touching – keep the dropper tip away from your eye, lashes and fingers.
- Close your eye – keep it closed for a minute or two, and press lightly on the inner corner near your nose so less of the drop drains away.
If your hands are unsteady, a family member can put the drops in for you. You can also try a drop guide, a small plastic holder that keeps the bottle lined up over your eye.
What Are the Side Effects of Eye Drops After Cataract Surgery?
The common side effects of eye drops after cataract surgery are brief stinging or burning, blurred vision for a few minutes after a dose and, with some drops, a bitter taste. All of these usually pass within minutes, and the taste comes from the drop draining through the tear duct into the throat.
Less often, steroid drops raise the pressure inside the eye, which is one reason your surgeon may measure your eye pressure at follow-up visits. Nonsteroidal drops can occasionally irritate the cornea, the clear front surface of the eye, when they are used for a long time. Your surgeon can usually manage both by changing the dose or switching to a different drop.
Pain that gets worse, redness that keeps increasing, vision that suddenly gets worse or a discharge from the eye are not typical drop side effects. These symptoms can be signs of infection or inflammation, so contact your surgeon the same day if you notice any of them.
Can You Use Dry Eye Drops After Cataract Surgery?

You may be able to use dry eye drops after cataract surgery, but check with your surgeon first, because the right timing and type can vary from person to person. The eye can feel dry, gritty or scratchy for several weeks as it heals, and lubricating drops, also called artificial tears, are often used to ease this.
Artificial tears are usually sold over the counter without a prescription. Points to discuss with your surgeon include whether a preservative-free drop suits your eye, how long to wait between artificial tears and your prescribed drops, and which types of eye drops to avoid while your eye heals.
For most people, dryness after cataract surgery improves within a few months, and your eye doctor can suggest other options if it does not.
Can Eye Drops Dissolve Cataracts?
Eye drops cannot dissolve cataracts, and none has been approved to reverse a cataract in people. So surgery remains the only proven treatment once a cataract starts to affect your daily life.
Until you need surgery, stronger glasses and brighter reading lights can make early cataracts easier to live with. And when the time comes, cataract surgery is one of the most commonly performed operations. For most people, the procedure itself takes less than an hour.
Final Thoughts: A Few Weeks of Drops for Clearer Sight
Using eye drops is a short and manageable part of recovering from cataract surgery. For most people the routine lasts three to four weeks, and the drops have clear jobs: preventing infection, controlling inflammation and keeping the eye comfortable.
Washing your hands and keeping to the schedule can help your eyes heal well. Once the course ends, you can enjoy the clearer, brighter vision that cataract surgery brings for most people, with perhaps an occasional lubricating drop to keep your eyes comfortable.
