Vitrectomy surgery is an operation performed in the operating room. In this procedure, three small openings are made in the white of the eye to give the surgeon access to the back of the eye. The sticky vitreous jelly is removed from the eye with a small instrument that fits through the openings in the white of the eye. This gives the surgeon access to the retina to perform many different types of procedures including macular hole repair, macular pucker repair, and retinal re-attachment. Many types of vitrectomy surgery will require the patient to assume a face-down position nearly full time for several days after the procedure. Your doctor will discuss this with you in detail if you require a vitrectomy surgery.
