Glaucoma Laser Surgery: YAG PI

YAG laser peripheral iridotomy (YAG PI) is performed almost exclusively for patients with Closed-Angle Glaucoma.  Laser surgery may prevent severe vision loss due to glaucoma, especially for people over the age of 40.

 

Aqueous fluid is a clear watery fluid that fills the chamber of the eye, between the cornea and the lens.  Aqueous fluid is made in the ciliary body of the eye, which is anatomically situated behind the iris.

In Closed-Angle Glaucoma, the drainage angle between the iris and the cornea narrows or closes.  Fluid cannot drain properly and pressure builds, sight deteriorates rapidly (in hours to days).  Closed-Angle glaucoma often needs emergency care; blocked fluid can cause severe pressure, pain, and permanent vision loss. 

During a YAG PI, Photo disruptive laser makes a tiny opening in the Iris to allow the aqueous fluid drain.  This typically results in resolution of the glaucoma attack and relieves pressure.  The Closed angle becomes an open angle. 

 

What to expect on the day of your YAG PI Laser Surgery

 

Prior to the procedure, our Technician will constrict the pupil with an eye medication known as Pilocarpine. The procedure itself is completed with the patient seated at the laser, and requires no sedation. After topical anesthesia eye drops are instilled, Dr. Bogart places a lens on the eye to better control the laser beam. The entire procedure takes only a few minutes. The lens is removed from the eye and vision will quickly return to normal.  This is an In & Out procedure.  Patients can drive themselves to and from this appointment.

 

Does a YAG PI Hurt?

 

The surface of the eye is numbed with topical anesthetics for this procedure, but the iris is not numbed.   Therefore, when the laser beam hits the iris to create the peripheral iridotomy, mild discomfort may occur.  In general, only a few very brief episodes of slight discomfort are associated with this procedure.  Also, some patients temporarily experience a slight brow ache above the treated eye.  Generally,  there is no pain involved post-operatively.
