Vitrectomy is a surgical procedure in which a retina specialist removes the vitreous humor gel (the jelly-like fluid filling the eye cavity).
Typically, this procedure is the first step in another surgery to give your doctor better access to the retina lining the back of the eye. This allows your doctor to perform a variety of repairs.
A vitrectomy may also be performed to place a therapeutic device or medication directly into the eye or diagnose a condition affecting the vitreous or retina.
