Cyclophotocoagulation For Glaucoma


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


Before your surgery:

  • Write down the correct date, time, and location of your surgery.
  • You may need to see your eye doctor 1 to 4 days before the surgery for a complete eye exam.
  • Arrange a ride home. Ask a family member or friend to drive you home after your surgery or procedure. Do not drive yourself home.
  • Do not drink alcohol for 48 hours before surgery.
  • Ask healthcare providers about directions for eating and drinking.

The day of your surgery:

  • Use your eyedrops and other medicines as directed. Bring your medicines with you to your surgery.
  • Do not wear earrings or hearing aids.
  • Do not wear makeup or lotion on your face.
  • You or a close family member will be asked to sign a legal document called a consent form. It gives healthcare providers permission to do the procedure or surgery. It also explains the problems that may happen, and your choices. Make sure all your questions are answered before you sign this form.


What will happen:

  • You will be given eyedrops to numb your eye. You may also be given medicine to help you relax. Your healthcare provider will use a face holder to help keep your head still during surgery.
  • Your healthcare provider will point a laser at the sclera (white part of your eye). The laser will go through the sclera to the ciliary body, which is where eye fluid is made. The laser will damage parts of the ciliary body so that it will make less eye fluid.

After your surgery:

Your healthcare provider will put eyedrops or ointment in your eye to decrease inflammation. He will check your eye pressure. You will be taken to a room where you can rest after your surgery. You will be able to go home when your healthcare provider says it is okay. An adult should stay with you for at least 24 hours after surgery.


  • You have a fever.
  • You cannot make it to your surgery on time.
  • You have questions or concerns about your surgery.

Seek Care Immediately if

  • You have severe eye pain.
  • You have a sudden change in your vision.


You may have severe eye inflammation. Your eye may bleed. Your vision may be blurry. You may need surgery more than once. Your eye pressure could become too low. If this happens, you may lose your vision, or you may lose your eye.
