Vitrectomy is a keyhole operation inside the eye that removes the vitreous gel so the surgeon can treat retinal problems at the back of the eye.
Why vitrectomy is performed
This surgery is used for conditions such as retinal detachment, macular holes, advanced diabetic eye disease, and persistent vitreous haemorrhage that will not clear on its own.
By removing the cloudy gel, the surgeon gains access to repair the retina, peel scar tissue, or stop bleeding.
- Performed under local or general anaesthetic depending on the case
- Uses tiny instruments passed through small ports in the white of the eye
- The gel is replaced with a clear fluid, gas bubble, or silicone oil
- Often combined with retinal laser or membrane peeling
Recovery and positioning
After vitrectomy, vision is usually blurred for several weeks while the eye heals and, if gas is used, until it gradually absorbs.
You may be asked to keep your head in a particular position so the gas bubble presses gently on the treated area.
- Follow posturing instructions carefully to give the best chance of success
- Flying and high altitude travel are unsafe while gas remains in the eye
- Regular follow up checks pressure, healing, and retinal attachment
- Seek urgent help if pain, redness, or sudden visual change develops
