I had both eyes done last year and even with my extreme wimpiness it was fine. I did insist on calming meds. Being able to see so well made it more than worth the anxiety.
Brought my mother-in-law here for her transition from rehab to home. Let's just say it is a lot.
The eye surgery I had is very similar to cataract surgery. I mostly recall them giving me some calming meds and asking how I felt and me being like “well 30 minutes ago when this was still 45 minutes away I was calm but it’s much closer now and my calm is burning down”
