My first laser iridotomy

Hello to everyone in this beautiful community. I would love some feedback. My Opth has advised me to go for an iridotomy, my first and i am very nervous. He informed me that in some cases, you get a permanent glare (he did not say what percentage of cases). I was wondering where i could find out the percentage of cases that suffer this side effect. He was also considering SLT but he decided that iridotomy would be better. I have plateau iris and a thin cornea and i am 43 years old. Thanks in advance. Blessings,
