He can see!
I was waiting to post until I could upload a few pics of Josh with his shades on, or seeing things sans glasses for the first time, but I've been torturing everyone by not posting.
Josh's PRK surgery was a success (so far), with a super easy and painless procedure followed by about twenty hours of sleep. He's a little sore now, using drops every 30 minutes when he's awake, and taking a fair amount of ibuprofen and Percocet.
The procedure is really remarkable - the lights from the laser were all blurry, then it did its thing, and immediately he could see it perfectly. The docs are hopeful for 20/20 vision or better, and he should be pretty well recovered in a couple days.
You can go ahead and keep those fingers crossed for a safe - albeit dry and uncomfortable - plane ride to Tokyo on Wednesday. And wish me luck now that I can't hide his glasses and do whatever I want while he can't see.
