Surgery: Lasik is a surgical procedure (can't be reversed), whereas crt is basically contact lens worn at night instead of during the day (can be stopped) discuss with your physician the risks/benefits/advantages/disadvantages of each.

LASIK versus CRT: Lasik eliminates the prescription permanently using a laser. Crt uses a contact lens to mold the cornea and only temporarily improves the vision.
