Vitrectomy Surgery

Vitrectomy is a type of surgery that treats disorders of the retina and vitreous. The retina is the light-sensing tissue at the back of the eye. The vitreous is a clear jelly-like substance that fills the middle of the eye. The vitreous is removed during the vitrectomy surgery and usually replaced with a salt-water solution. Vitrectomy surgery often improves or stabilizes vision.

When do you need a vitrectomy?

  • Diabetic retinopathy for any bleeding or scar tissue present
  • Retinal detachments
  • Infections or foreign bodies inside the eye
  • Macular hole
  • Macular pucker (epiretinal membrane)
  • Certain problems after cataract surgery

The surgery is performed while looking into your eye with a microscope. After anesthetic, tiny instruments are introduced into the eye through small incisions made on the white part of the eye.

Depending on your condition, the surgeon will do one or more of the following:

  • Remove vitreous (including material that causes floaters)
  • Remove scar tissues present
  • Placing retina to its normal position
  • Remove foreign objects
  • Treat retina with laser or cryotherapy to reduce bleeding or fix a tear
  • Place a gas bubble to help retina remain in its proper position.

After surgery, you can expect some discomfort and you will need to wear an eye patch for a short amount of time. You will be prescribed eye drops after the surgery and will advise you when you can resume normal activity.
