Yag Iridotomy - Laser Peripheral Iridotomy

Laser peripheral iridotomy is a treatment for narrow angle glaucoma. The surgeon uses an Nd:YAG laser to create a small hole in the peripheral iris. This improves the circulation of fluid inside the eye and widens the anterior chamber angle. Fluid which is produced behind the iris has easier access to the eye's internal drainage system. Sometimes this lowers the intraocular pressure, but that is not the primary goal of laser peripheral iridotomy. The primary goal of the procedure is to lessens the risk of acute angle-closure glaucoma.

What to expect on procedure day

You will be asked to arrive at Peninsula Eye Surgery Center one hour before the scheduled time of surgery. After checking in and being admitted to the preoperative area, a nurse will administer some eye drops which will constrict your pupils. After 15 to 30 minutes, you will be escorted to the laser room, where the procedure will be performed. Your surgeon will use the Nd:YAG laser to place a small hole in the peripheral iris of the involved eye(s). During the procedure, you will see a brief flash of light, hear a clicking sound, and possibly feel a slight stinging sensation. The procedure will last only a few minutes. Your eye pressures will be checked shortly after the treatment, and you will be discharged home to resume your normal activities. Your doctor might prescribe some anti inflammatory eye drops to be used for a few days after the procedure. Patients occasionally experience transient mild redness, discomfort, light sensitivity, and blurred vision.
