A vitrectomy is a surgical procedure used to address severe retinal detachments, large retinal tears, vitreous hemorrhage, extra tissue (membranes) on the retina, or severe infections in the eye.
During the surgery, small openings are made in the eye to position a fiber-optic light, specialized scissors, and delicate forceps. The vitreous gel (the clear gel that fills most of the eyeball) is removed and replaced with a gas that refills the eye and helps reposition the retina. The gas is eventually absorbed and replaced by the eye’s natural fluid.
After the surgery, patients may need to use eye drops for several weeks to allow the surface of the eye to heal. Due to the gas used during surgery, patients may be required to maintain specific head positions or sleep in a certain way to aid recovery. The quality of eyesight regained after surgery depends on the eye's condition prior to surgery and can range from complete 20/20 vision to vision sufficient only for safe walking.
