You have diabetic retinopathy. This is an eye condition that happens when diabetes harms blood vessels in the back of the eye. It can cause cloudy eyesight and other problems. A vitrectomy surgery may help you see more clearly.

The gel (vitreous humor) that fills the eye is normally clear. But with diabetic retinopathy, this gel can be clouded with blood or debris. During vitrectomy, the eye doctor takes out the cloudy gel. It's replaced with fluid, silicone oil, or gas. The retina may also be treated if there's scar tissue. This can help you see more clearly. If you still have problems seeing after your surgery, you may need more surgery. A vitrectomy may make it possible to do other procedures to help restore eyesight, such as laser treatments for diabetic retinopathy, retinal detachment, and treatment of macular holes.

• Tell your doctor about all medicines you take. This includes over-the-counter and prescription medicines, vitamins, herbs, and supplements. It also includes aspirin, ibuprofen, ginkgo, and warfarin or other blood thinners.
• Before surgery, you'll meet with a doctor (anesthesiologist) who gives medicine to control pain. You'll talk about the type of pain medicine and sedation (anesthesia) you'll have during the surgery.
• You'll be asked to sign a consent form. This explains the surgery to be performed and the risks involved. By signing the form, you agree to have the surgery. Have all of your questions answered before signing the form. You will also be asked to sign a consent form for anesthesia to be given.

During the surgery, the doctor makes small cuts (incisions) in the white of the eye (the sclera). Tiny tools are put through the cuts. The vitreous is removed. It's replaced with something that holds the retina in place. This may be saltwater (saline) solution, silicone oil, or a gas bubble. The surgery may take a few hours.

• An adult family member or friend must drive you home after the surgery. Wear dark sunglasses on the way home.
• Before leaving, you'll be told how to protect and care for your eye. You'll need to use eye drops for a few days. This is to ease swelling and prevent infection. Don't rub, touch, or bump your eye.
• You may need to wear an eye patch for a few days or weeks.
• The surgeon may tell you to lie face down for a while after the surgery. This helps the retina heal.
• Ask your doctor how long to wait before you can lift things, exercise, or swim. Ask when you can drive and go back to work.

Before you leave, know what number to call if you have questions or problems when you get home. You should also have written discharge instructions. If you have low vision, ask the doctor to print the information in a larger size you can read.

Vitrectomy may cause some pain. You'll be given medicine to control this pain. If pain continues or gets worse, tell your doctor.

Risks and possible complications include:

• Swollen or droopy eyelid
• Double or blurry vision
• Detached retina
• Bloody white of the eye (sclera)
• Watery or red discharge
• Pain
• Cloudy eye lens (cataract)
• Eyesight doesn't get better

After you go home, call your doctor or seek medical care right away if you have:

• More pain, redness, or discharge that may mean you have an eye infection
• Problems seeing after the eye patch is removed
