I almost had the procedure, but due to shingles always present on my left temple near my eyes, even had it on the tip of my nose hours before the laser cutting commenced.
I’m very light sensitive too and heard that the worst effect can be diminished night vision, sometimes light sources will have a starburst pattern. Actually worst would be blindness, only 1 eye at a time just in case...
Although it is extremely rare a few people have been left with so much pain after the surgery that they ultimately committed suicide. It works well for the vast majority of patients, but it is not without risks.
True words
Most excellent advice
