3 weeks?! is that just for going out in the boat? You may want to check on the time frame for wakeboarding/waterskiing, I think its more like 3 months. That is what they recommended to me when I had it done. apparently the flap of the cornea that they cut is easily ruptured in that time period and waterskiing/wakeboarding is extra dangerous as there is a chance that water can be forced into the eye. I waited about a month and then I wore a small pair of goggles for the rest of the summer to prevent water from entering the eye. something like this...
