About Vitrectomy

What is Vitrectomy?

Vitrectomy is an advanced surgery done by our specialists to remove the gel-like substance called ‘vitreous humour’ from inside your eye. This helps them get better access to your retina.

The vitreous humour acts as a support structure for your eye and makes up for 2/3rds of the eye volume.

When / Why do I need it

When do I need Vitrectomy?

If you have an eye condition that causes problems with your retina (the light-sensitive layer of tissue at the back of your eye) or vitreous (the gel-like fluid that fills your eye), our experts may recommend Vitrectomy.

How do our experts perform it

There are mainly two types of Vitrectomy surgeries.

Anterior Vitrectomy

Sometimes, after complex surgeries for cataracts, corneas, or glaucoma, the gel inside the eye (vitreous) can come forward through the pupil. This needs to be cleared out to reduce inflammation and prevent problems with the cornea and retina later on.

Pars Plana Vitrectomy Surgery

Pars Plana Vitrectomy, done by our retina specialists, is a surgery for issues in the back part of the eye. It involves making small openings in the eye to remove the vitreous gel using special tools. Afterwards, saline, gas bubbles, or silicone oil might be put in to help the retina heal, often requiring the patient to stay in a face-down position for a while.


The length of a vitrectomy surgery can vary, from half an hour to a couple of hours, depending on what’s being treated. Before the surgery starts, the surgeon will give you the choice to stay awake or have numbing shots in your eye.

Or, in many cases, you’ll be given general anaesthesia to put you to sleep. Here’s what happens during the surgery:

  • The surgeon makes a small cut in the outer layer of your eye, called the sclera.
  • They use a tiny tool to remove the vitreous fluid, filling the eye with a liquid that’s like normal eye fluid.
  • Then, they clear out any debris or abnormal proliferative tissue in the eye.
  • After the vitrectomy, the surgeon might do other repairs your eye needs.
  • Once everything looks good, your eye will be filled with silicone oil, air or saline.
  • Usually, stitches aren’t needed, but if they are, the surgeon will put them in.
  • Your eye will be treated with ointment and covered with a patch.


After the surgery, your doctor will prescribe eye drops to prevent infection and may recommend pain relievers if needed. You’ll also need to schedule regular eye check-ups for the next few weeks.

Take it easy for a few days; avoid activities like reading, driving, and exercising. Use the eye drops prescribed by your doctor to prevent discomfort. Your doctor may suggest lying face down for a period to help speed up healing in some cases.

In vitrectomy, the ophthalmologist removes some or all of the vitreous from the middle of your eye. They then replace it with a saline solution or a gas or oil bubble.
