Advice after your nerve block for surgery

Introduction
YAG laser peripheral iridotomy is performed to treat or prevent a sudden rise in pressure inside the eye - acute angle closure glaucoma.
A sustained rise in pressure can cause a permanent loss of peripheral and central vision. The iridotomy allows fluid to circulate freely within the eye minimising the risk of a sight-threatening pressure rise.
Indications of the laser treatment
- Prevent an attack of acute angle closure glaucoma.
- Treat an attack of acute angle closure glaucoma.
- Treat chronic glaucoma where the drainage channel is very narrow.
The procedure is performed to preserve sight; it will not restore or improve the sight.
What takes place during the procedure?
The procedure is an out-patient procedure carried out in the eye clinic. Your vision may be disturbed for the rest of the day and it is advisable not to drive that day.
You will be sitting at a machine similar to that used during your examination in eye clinic, with your forehead resting against a headpiece and chin resting in a chin rest.
Some eye drops will be given to numb the surface of the eye prior to the laser treatment to prevent you from blinking, and a mirrored contact lens will be placed on the eye for focusing the laser beam.
You will see some bright flashes of light and hear some clicking noises. The procedure usually takes a few minutes.
Your eye may become pink and a little sore , eye drops will be given to help the eye settle down.

- Rise in eye pressure
- Inflammation
- Bleeding in front of the eye
- Clouding of the cornea
