What does vitrectomysurgery involve?

Macular hole surgery is a form of keyhole surgery performed under a microscope.

Three small incisions (one millimetre in size) are made in the white of the eye and very fine instruments are inserted.

First, the vitreous jelly is removed (vitrectomy) and then a very delicate layer (theinner limiting membrane) is carefully peeled off the surface of the retina around the hole, to release the forces that keep the hole open.

The eye is then filled with a temporary gas bubble, which presses the hole flat onto the back of the eye to help it seal.

The bubble of gas will block the vision while it's present, but it slowly disappears over a period of about four to eight weeks.

Macular hole surgery usually takes 45-90 minutes and can be done while you're awake (under local anaesthetic ) or asleep (under general anaesthetic ).Most patients opt for a local anaesthetic, which involves a numbing injection around the eye, so no pain is felt during the operation.

You may be able to go home the same day,but most patientsneedto stay in hospital overnight.
