YAG PI is performed for patients with narrow angles, narrow angle glaucoma, or
acute angle closure glaucoma.
It involves creating a tiny opening in the peripheral iris, allowing aqueous fluid to
flow from behind the iris directly to the anterior chamber of the eye. This allows
an opening up of the angle of the eye.
How is the Procedure done?
Anaesthetic drops are applied.
You have to sit in front of the slit lamp with
your chin on a chin rest (an attachment)
and your forehead against the bar.
Doctor will apply a contact lens to your eye
and focus on crypts in peripheral iris
Laser shots are delivered to create a hole
in the peripheral iris to allow aqueous to
flow through.
The procedure takes about 5 minutes.
What are the Side Effects?
The side effects after YAG Laser PI are mild, uncommon and short-lived:
Redness, light sensitivity, and discomfort for a few days after the procedure.
