About Anti-VEGF

What are Anti-VEGF agents?

Your body produces a protein called Vascular Endothelial Growth factor (VEGF) which is responsible for producing new blood vessels and maintaining them. But in conditions like diabetic retinopathy or age-related macular degeneration, it creates abnormal vessels which tend to bleed, leak and ultimately lead to oedema and vision loss.

Anti-VEGF agents are a group of medications which block the activity of VEGF, therefore reducing bleeding and vascular leakage.

How our experts treat it

After our experts analyse your condition, they determine whether an Anti-VEGF is ideal for you.

The surgery itself is quick and causes minimal discomfort.
Our surgeons use topical anaesthetic to numb your eyes. They then clean your eyes and surround them with a drape. The Anti-VEGF is injected through the white part of the eye with a fine needle. We then gently massage your eye and antibiotic drops are applied.


Complications after these injections are very rare. But sometimes, problems happen from the injection itself, not the medicine. Here are some common ones:

  • Mild eye pain or ache for a couple of days
  • Floaters might take at least a few days to go away
  • White part of your eyes might have a red spot at the injection site
  • Your eyes might feel rough or irritable

It’s normal for such things to happen after Anti-VEGF injections. But if they don’t go away after a while, it’s best to talk to your doctor and get checked out.

Make sure to talk to your eye doctor about what you should and shouldn’t do. Avoid wearing eye makeup, don’t strain your eyes, and try not to rub them too much. This way, you can prevent any irritation that might interfere with the procedure. Blood sugars should be under control.

Before starting, the surgeon might have you read a chart to test your vision. They’ll give you eye drops to numb your eyes, so you won’t feel any pain.

Anti-VEGF injections are typically given to patients with conditions where abnormal blood vessels leak into the retina, leading to central vision loss. These injections are administered into the back of the eye to prevent the growth of these blood vessels and control the leakage of blood.
