A vitrectomy is an operation when the surgeon removes (under the microscope) the vitreous jelly from the cavity of the eye...and replaces it either with gas or saline.Vitrectomy surgery is used for various conditions....most commonly...bleeding or scarring from diabetes, certain retinal detachements...or severe injuries to the eye.
Patients are typically awake...but sedated during such surgery...the eye is frozen with local anaesthesia.
