Cataract Surgery Preparation: Recovery Tips and Managing Side Effects

Written by healthwords.ai's team of doctors and pharmacists based in UK | Updated: 15 Jul 2025 | 5 min read

Cataracts are a common eye problem, especially as people get older. A cataract happens when the clear lens inside your eye becomes cloudy. This can make your vision blurry, make it hard to see at night, and make you more sensitive to bright lights. If cataracts are not treated, they can make everyday activities like reading, driving, or recognizing faces very difficult. The good news is that cataract surgery is a safe and effective way to restore clear vision.

What Are Cataracts?

Cataracts form when proteins in the lens of your eye clump together, creating cloudy spots that block light from reaching the back of your eye (the retina). At first, you might only notice slightly blurry vision or need brighter light to read. Over time, cataracts can get worse and make it much harder to see.

Common symptoms of cataracts:

  • Blurry or cloudy vision

  • Sensitivity to bright lights or glare

  • Trouble seeing at night, especially when driving

  • Colors look faded or yellow

  • Needing new prescription glasses more often

If these symptoms make daily life hard, your eye doctor may suggest cataract surgery.

Types of cataract surgery

There are two main types of cataract surgery. The type you need depends on how bad your cataract is and if you have other eye problems.

  • Phacoemulsification (Phaco): This is the most common type. The doctor makes a tiny cut in your eye and uses a small tool with ultrasound waves to break up the cloudy lens. The pieces are removed, and a clear artificial lens (called an intraocular lens or IOL) is put in its place. This method heals quickly and usually doesn’t need stitches.

  • Extracapsular Cataract Extraction (ECCE): If the cataract is very hard or dense, the doctor makes a larger cut and removes the lens in one piece before putting in the new lens. This method takes longer to heal because the cut is bigger.

Laser-Assisted Surgery: Some surgeries use a special laser to make cuts and soften the lens. This can be more accurate, but it may cost more and isn’t always covered by insurance.

Who Needs Cataract Surgery?

Doctors usually recommend cataract surgery when cataracts make daily life difficult. Surgery isn’t always urgent, and some people can manage mild symptoms with new glasses or brighter lights for a while. Surgery is needed when:

  • You can’t do normal tasks like reading or driving

  • Vision tests show your eyesight is badly affected

  • Other eye problems, like glaucoma, could get worse if you don’t treat the cataract

Sometimes, both eyes need surgery, but the operations are usually done a few weeks apart.

Risks and Benefits

Cataract surgery is very successful, with over 95% of people seeing better afterward. Like any surgery, there are some risks:

  • Infection: Rare, but can happen. Doctors use antibiotics to reduce this risk.

  • Swelling or Inflammation: Some people get swelling or irritation, which is usually treated with eye drops.

  • Retinal Detachment: Very rare but serious. If you see flashes of light or lots of floaters, call your doctor right away.

Most people feel that the benefits: clearer vision and easier daily life: are much greater than the risks.

Getting ready for surgery

Before surgery:

  • Your eye doctor will check your eyes and overall health.

  • They will measure your eye to pick the right artificial lens.

  • You’ll talk about lens options. Some lenses help you see at one distance, while others can help with both near and far vision (these may cost extra).

  • You might need a general health check, like blood pressure or blood sugar tests.

How to prepare:

  • You might need to stop taking some medicines, like blood thinners, a few days before surgery (ask your doctor first).

  • Don’t eat or drink after midnight before surgery.

  • Arrange for someone to drive you home after the procedure.

At home:

  • Make your home safe by clearing away things you could trip on.

  • Have groceries, medicines, and eye drops ready.

  • Get sunglasses to protect your eyes from bright light after surgery.

Mental preparation:

  • Learn about the surgery to help calm your nerves.

  • Try deep breathing, meditation, or calming music.

  • Focus on the benefits of better vision.

What Happens During Surgery

  • You’ll arrive at the clinic or hospital a few hours before surgery.

  • Nurses will check your health and get you ready.

  • You’ll get eye drops to widen your pupil and numb your eye. You might get medicine to help you relax, but you’ll be awake.

  • The surgery usually takes 15 to 30 minutes per eye.

  • The doctor makes a small cut, removes the cloudy lens, and puts in the new lens.

  • Most cuts heal on their own and don’t need stitches.

  • After surgery, you’ll rest for a short time, get your eye checked, and receive instructions and eye drops to use at home.

  • You’ll wear a protective shield over your eye for a day or two.

Recovery and side effects

Most people notice better vision within a few days, but full healing can take several weeks.

First 24 hours:

  • Vision may be blurry or cloudy. This should get better soon.

  • Mild discomfort or a gritty feeling is normal. Don’t rub your eye.

First week:

  • Vision should get clearer, but you might still be sensitive to light.

  • You’ll have a follow-up appointment with your doctor.

First month:

  • Most people can return to normal activities like reading and driving in a few days.

  • Avoid heavy lifting, strenuous exercise, and swimming for at least a month.

Common side effects:

  • Blurry vision: Use your eye drops and wear sunglasses or a shield as advised.

  • Dry or itchy eyes: Use lubricating eye drops if your doctor says it’s okay.

  • Light sensitivity: Wear sunglasses outdoors and avoid bright lights inside.

  • Mild pain: Over-the-counter pain medicine like acetaminophen can help. Don’t use ibuprofen or aspirin unless your doctor says it’s okay.

When to call your doctor:

  • Severe pain that doesn’t go away

  • Vision suddenly gets worse or doesn’t improve

  • Redness, swelling, or discharge from the eye

  • Flashes of light or a sudden increase in floaters

Tips for a smooth recovery

  • Use all prescribed eye drops exactly as your doctor tells you.

  • Avoid heavy lifting, bending over, and swimming for at least a week.

  • Wear your protective shield while sleeping for the first week.

  • Wear sunglasses outside to protect your eyes from light.

  • Eat healthy foods like leafy greens, citrus fruits, nuts, and fish.

  • Drink plenty of water and avoid smoking.

Helpful products:

  • Lubricating eye drops

  • Sunglasses with UV protection

  • Cold compresses for swelling
