I had RK done 20 years ago, when it was still very new. I held off until they would do both eyes in the same visit, yes, they only used to do one at a time just in case.
I NEVER thought I would be able to make it through the surgery as you are awake and you do watch them take a knife to your eye. They gave us a happy pill and we filed through like an assembly line. Everything went fine and it took three days in a dark room to recover. Eyes were still sensitive for a week or so after but I was able to see and work.
The surgery also came with the warning I could never wear contacts afterwards so if my eyesight deteriorated I would be wearing glasses. I could never stand contacts for more than an hour at a time before the surgery so that wasn't an issue to me.
So now about 20 years later I have had to go back to glasses for work, sitting at a computer and anytime I need to see small things, or read small print but it is better than glasses all the time. We will see what the next 20 years bring. Overall I am satisfied with my decision.
I am not sure if this helps as mine was RK not Lasik but maybe it will help you think of questions to ask and things to consider before moving forward.
