What is Cataract Surgery An Easy-to-Understand Guide

What is a Cataract?

A cataract occurs when the lens in your eye becomes cloudy. This lens is normally clear and helps you focus on what you see. When it becomes cloudy, it can make your vision blurry.

Why Do Cataracts Form?

Cataracts can form for various reasons, such as ageing, injury to the eye, or exposure to too much sunlight. Health conditions like diabetes can also increase your chances of getting a cataract.

When is Surgery Recommended?

If the cataract affects your everyday life, making activities like reading or driving difficult, your eye doctor may recommend cataract surgery. The surgery aims to remove your cloudy lens and replace it with an artificial lens that is clear.

How is the Surgery Performed?

  1. Preparation: Before surgery, tests are conducted, and your medical history is reviewed.
  2. Before surgery: No need to fast; you can have breakfast as usual.
  3. Anaesthesia: Local anaesthesia numbs your eye for the surgery.
  4. Procedure: A painless, 2mm incision is made, the cloudy lens is removed, and a new lens is inserted.
  5. Closure: The small incision self-seals, typically without stitches

What to Expect After Surgery

You will likely wear an eye patch for a short time after the surgery. Your doctor will prescribe eye drops to aid in healing and prevent infection. Improvement in vision usually occurs within a few days, with full recovery taking about 8 weeks.

Risks and Considerations

Like any surgical procedure, cataract surgery comes with risks, such as infection and complications involving the retina at the back of the eye. It is important to discuss these risks with your eye doctor.


Cataract surgery is a common and effective way to improve vision by replacing a cloudy lens with an artificial one. If you are experiencing vision problems, consult an eye doctor to see if cataract surgery is right for you.
