Yag Peripheral Iridotomy
YAG PI 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 typically allows an opening up of the angle of the eye. The narrow or closed angle thus becomes an open angle.
The procedure itself is completed with the patient seated at the laser, and requires no sedation. Topical anaesthesia eye drops are instilled, a lens is placed on the eye to better control the laser beam. In general, only a few very brief episodes of slight discomfort are associated with this procedure. However, generally there is no pain involved post operatively. The entire procedure takes only a few minutes.
