Hi,
I do not think that the surgery can hurt you.It is an easy surgery where everything is done very quickly and as far as your nerve issue is considered ,I do not think that if you get the correct doctor you will have any kind of issue.So i can only request you to be careful in whatever you do.Please choose your doctor wisely as a doctor can make or break your life forever and this time it is related to your eyes.And stop worrying just be and feel confident.
thanks.
