I have a first class medical exam after 2 weeks. i did prkbefore two weeks. will i have 20/20 by that time?

PRK and med school: First - good luck on your exam. I hope you used my book... Micro made ridiculously simple. To answer your question - the vision after prk heals rather quickly - and in 99.5% of cases - your vision should be just fine after 2 weeks for taking an exam. I hope this helps.

Usually: After prk the vision should be pretty good after 2 weeks and usually continues to improve. On occasion it may take longer for the vision to recover so don't panic if you are not 20/20 at the 2 week mark.
