YAG Laser PI (Peripheral Iridotomy)

YAG Laser PI (Peripheral Iridotomy)

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.
  • Short-lived increase in eye pressure.
  • Temporary blurred vision.
  • Temporary inflammation.
