Not sure where you went but my procedure involved nothing of the sort... ?
Full disclosure: I had PRK not LASIK. PRK is the older tech that I was forced to have because of a severe case of GPC. The difference at least in simple terms is as follows: With LASIK they use a laser or a blade to slice a flap off of your eye. They do the correction then the flap is repositioned. This results in extremely quick healing because it resembles a paper cut. With PRK they remove the front covering of your eye. Do (seemed like) the exact same correction procedure but then let the surface of your eye grow back from 'scratch'. Healing is significantly longer in duration and discomfort BUT they can use this method where LASIK isn't good (in my case severe risk of hemorrhage) AND they are able to do a better job at repair as well with less of the side effects (my night vision was completely unhindered).
I was fully conscious and had full eyesight for the entire procedure. It's actually kind of surreal as the whole thing is going on then (with PRK) they place a "band-aid" contact on the eyes while they do their initial healing. 5 days later those come off and you enter the "OCD with 5 different kinds of eyedrops" phase for about a month. After the 5 days tho I was fully functional just my comfort and vision improved as the days passed. Completely normal by about 3 months. Immediately after the procedure I tested 20/10 but settled out to about 20/15 as the healing progressed.
Honestly it's the best money I've ever spent. Yes there is the probability that my vision will slip over time but 6 years in with no complications or slide yet and I'm happy with the investment. Eventually as I get older this doesn't stop the tendency towards presbyopia either but I'll take readers over my old vision any day!
