I had the PRK as well. I don't remember the "band-aid" contact, but that was almost 20 years ago. I do remember the different eye drops and how I would set my watch to multiple alarms through the day so that I would remember to use them. I was warned that the most common cause of post-op complications was failure to use the drops, so I took that seriously. I had no serious complications, other than halo effect at night, but that diminished over time.
I do remember two things when they did the procedure. The first was the strong hands on either side of my head that prevented from moving and the smell. It took me a moment to realize that was my eyeball tissue being vaporized.
