45 yr-old had Lasik monovision 1.5 year ago. Left eye was left -1.25 on purpose. Dominant right eye was undercorrected by -0.50 and -0.25 astigmatism. Distance vision is a bit weak. However I also noticed closeup vision reduction when trying contact to fully correct right eye. My dr can do PRK enhancement on right eye (not lasik). I'd like a second opinion: 1. Is it worthwhile to get PRK to fully correct my right eye? 2. Would it be possible to get PRK only correct half prescription of right eye eg. 0.3?
