Cyclophotocoagulation for Glaucoma

Medically reviewed by Last updated on Dec 2, 2022.

Cyclophotocoagulation is a laser procedure to decrease the amount of fluid your eye makes. Glaucoma is caused by fluid buildup behind the eye. This procedure will decrease the pressure on your optic nerve and help slow or prevent further damage and vision loss. You may need this procedure on one or both eyes.


Call your eye doctor if:

  • You have severe eye pain.
  • Your vision suddenly becomes worse.
  • You have a fever or chills.
  • Your eye is red, swollen, and draining pus.
  • You have questions or concerns about your condition or care.


  • Medicines may be given to help decrease inflammation, eye pressure, and help your eye heal.
  • Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell your provider if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Care for your eye:

  • Do not rub your eye.
  • Ask when you can remove the eye patch.
  • Wash your hands carefully before you use eyedrops. Do not let the tip of the eyedropper touch your eye or eyelid.
  • Do not wear eye makeup for 1 week after your procedure.
  • Wear sunglasses during the day to protect your eye.
  • Try to sneeze or cough gently.
  • Do not bend over at the waist for 1 to 2 days after the procedure.
  • Do not get in swimming pools or hot tubs until your eye doctor says it is okay.

Medical alert identification:

Wear medical alert jewelry or carry a card that says you have glaucoma. Ask where to get these items.

Medical Alert Jewelry

Follow up with your eye doctor as directed:

You will need to return to have your eye checked. Bring your eyedrops and other medicines with you. Write down your questions so you remember to ask them during your visits.
