The Definition of Vitrectomy

A vitrectomy is a surgery performed on the eye to remove some or all of the vitreous, the clear internal jelly, from the eye.

Description

• Vitrectomy is a term referring to a group of operations usually performed in the deeper sections of the eye. It is generally outpatient surgery, meaning the patient does not need to stay in a hospital.

Procedure

• The procedure is performed using a microscope and special lenses. These lenses provide a clear image of the back of the eye for the surgeon. The surgeon then makes several minute incisions into the surface of the sclera, before inserting microsurgical instruments designed to provide light in the back of the eye, maintain the shape of the eye, and cut and remove the vitreous within.

Special Techniques

• The surgeon may also treat the retina using a laser to seal blood vessels, insert a gas bubble to seal a macular hole during macular hole surgery, or fill the eye with silicone oil to keep the retina in position after reattachment surgery.

Conditions Treated with Vitrectomy

• Vitrectomies are needed to treat macular holes, retinal detachment, pre-retinal membrane fibrosis, bleeding inside the eye, injury or infection, problems from previous eye surgeries and complications from diabetic retinopathy.

After the Procedure

• Following the procedure, the eye is patched for the day. Anesthesia numbs the eye and temporarily inhibits blinking, so the patch must be kept on until normal blinking is possible. Patients can expect to feel discomfort for several days, as well as a scratchy sensation or occasional sharp pain.
