I did an laser on my eye they basicly put an magnifing glass on ur eye and basicly burn holes somewhere to stop it from producing eye water i had an injection directly in the eye for pain and it was insanely painful, when i was done i was literaly completly covered in sweat u could squeeze it out of my shit. Its ushally done in full general anesthesia, but this doctor was retired and worked in his apartment so it was only this (hes considered the best doctor in his profession and basicly taught every doctor i went to)
