The Vitrectomy Procedure
Vitrectomies can be performed under local or general anesthesia. During vitrectomy surgery, your surgeon will first remove the blood-clouded vitreous gel from your eye. The vitreous tissue is then cut and removed one piece at a time and replaced with a special salt solution in order to maintain the eye’s proper shape and pressure. The inside of the eye is illuminated, and the surgeon views the eye through a microscope.
In the case of a severely detached retina, it may be necessary to inject expandable gas into the eye during vitrectomy surgery. The expanding gas bubble pushes against the retina, helping it reattach. Patients must often lie face-down for two to four days until the gas bubble dissipates.
During vitrectomy surgery, a laser may be used to perform photocoagulation across the surface of the retina. This photocoagulation helps to prevent the formation of scar tissue and bleeding, and may also prevent the future growth of abnormal blood vessels.
