Find a detailed description of a virectomy at WebMD.com, AllAboutVision.com or GetEyeSmart.com. A virectomy is a surgical procedure to remove the vitreous gel from the middle of the eye. This procedure is performed if there is blood in the vitreous gel that does not clear on its on.
A surgeon inserts an instrument into the eye, cuts the vitreous gel and removes it via suction. The surgeon may perform this procedure to gain access to the back of the eye for further surgical treatment. After surgery, a silicone oil or gas bubble is injected into the eye to press the retina against the eye wall.
