Glaucoma Surgery

A procedure to treat glaucoma by releasing pressure inside the eye. There are two common methods: laser and incisional.

The eye is normally bathed by the aqueous humor, a clear fluid that flows in and out of the eye chamber. In glaucoma, this fluid drains too slowly out of the eye. As the fluid builds up, pressure inside the eye increases. If this pressure is not controlled, it can cause damage to the optic nerve and other parts of the eye, and loss of vision. It is important to note that while glaucoma surgery may save your remaining vision, it does not improve or restore sight.

Parts of the Body Involved

Eye (lens, conjunctiva, iris, sclera)

Reasons for Procedure

  • To release the amount of pressure in the eye
  • To reduce and/or prevent loss of vision

Risk Factors for Complications during the Procedure

  • Obesity
  • Smoking
  • Diabetes
  • Recent or chronic illness
  • Heavy bleeding
  • Infection

What to Expect

Prior to Procedure:
  • Continue to take your eye drops
  • If you are having the incisional technique, do not take aspirin, aspirin-containing products, or anti-inflammatory drugs (e.g., ibuprofen) 10 days before the procedure
  • Arrange for a ride to and from the procedure
During Procedure

Outcome

Laser surgery can successfully relieve intraocular pressure, but the effects can wear off over time. The pressure increases again in more than half of all patients two years after the initial laser surgery. In most cases, medications are still necessary to control and maintain eye pressure, but surgery may lessen the amount of medication needed.

Call Your Doctor If Any of the Following Occurs

  • Signs of infection, including fever and chills
  • Sudden change in vision
  • Sharp pain or blood in your eye
  • Redness, swelling, increasing pain, excessive bleeding, or discharge in the surgical area
