Cyclophotocoagulation for Glaucoma


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.


Before your procedure:

  • Informed consent is a legal document that explains the tests, treatments, or procedures that you may need. Informed consent means you understand what will be done and can make decisions about what you want. You give your permission when you sign the consent form. You can have someone sign this form for you if you are not able to sign it. You have the right to understand your medical care in words you know. Before you sign the consent form, understand the risks and benefits of what will be done. Make sure all your questions are answered.

During your procedure:

  • You will be given eyedrops to numb your eye. You may also be given medicine to help you relax. Your eye doctor will use a face holder to help keep your head still during the procedure.
  • Your eye doctor 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 procedure:

Your eye doctor will put eyedrops or ointment in your eye to decrease inflammation. He or she will check your eye pressure. You will be taken to a room where you can rest after your procedure. You will be able to go home when your eye doctor says it is okay. You may be given to help decrease inflammation, eye pressure, and help your eye heal.


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