Your visit to the outpatient department will last around one and a half hours. We will constrict your pupil using drops. An anesthetic drop will numb your eye and a small contact lens will be placed on the surface of the eye so that you do not need to worry about blinking. You will hear the laser make a quiet sound with each pulse, the procedure typically taking a few minutes. You will be offered a refreshment, then asked to wait for an hour so that we can check the pressure of your eye provide you with a short course of drops to use afterwards.
Does YAG PI hurt?
No, you will experience a sensation similar to a light pin-prick with each pulse with two PI’s typically made for each eye.
Does YAG PI need to be repeated?
Typically no. Up to 10% of iridotomies can however, close with time so if you have not undergone cataract or RLE surgery the procedure may need to be repeated. As your eye may also be at risk from developing glaucoma, you should have regular eye check-ups.
When can I return to normal activities?
Immediately, there are no restrictions on activities but you will be asked not to drive immediately after your appointment as your pupil will be dilated.
What are the risks of YAG PI?
Risks of YAG PI are low as the energy transmitted is low and highly focused. The following risks however have been reported including: small bleeds from the iris, typically controlled by gentle pressure on the eye, inflammation, swelling or oedema of the macula, raised pressure in the eye and rarely noticing a light reflection at the periphery of vision.
Do I require treatment afterwards?
We will provide you with a short course of eyedrops, four daily for 7-14 days following treatment.
