Vitrectomy is the surgical removal of the vitreous gel from the middle of the eye camera. It may be done when there is a retinal detachment, because removing the vitreous gel gives your eye doctor (ophthalmologist) better access to the back of the eye. The vitreous gel may also be removed if blood in the vitreous gel (vitreous hemorrhage) does not clear on its own.
During a vitrectomy, the surgeon inserts small instruments into the eye, cuts the vitreous gel, and suctions it out. After removing the vitreous gel, the surgeon may treat the retina with a laser (photocoagulation), cut or remove fibrous or scar tissue from the retina, flatten areas where the retina has become detached, or repair tears or holes in the retina or macula.

What To Expect After Surgery
Vitrectomy may require an overnight hospital stay. But it may sometimes be done as outpatient surgery. The surgery lasts 2 to 3 hours. Your eye doctor will determine if the surgery can be done with local or general anesthesia.
You may need to position yourself in a certain way at home for a while. Your doctor will tell you what position to lie in so that the gas or oil can push against the detachment.
