What is vitrectomy surgery?

During the vitrectomy, your surgeon will use very small (25-gauge) instruments to enter the back of the eye, through the sclera (white part of the eye). As the vitreous is removed it will be replaced with sterile saline. Typically, the vitreous is removed nearly in entirety – it is not necessary and will not regenerate. The saline will be replaced with aqueous humor over a few days. Following removal of the vitreous, attention will then be paid to the rest of the surgery, as needed. You should expect to be calm and comfortable during surgery, and if you are not, please speak up and inform the surgeon and anesthesiologist.
Once the surgery is over, the surgeon will remove the drapes and patch your eye closed. Please do not speak until the eye is fully patched.
