What is the difference between the lasik and paragon crt?

Surgical vs Lens: Lasik is a surgical procedure that will permanently change the shape of your cornea to diminish its myopia, hyperopia or astigmatism. Paragon crt is a brand of contact lenses(ortho k) worn overnight to temporarily warp your cornea and temporarily reduce myopia during the day.

LASIK permanent: Lasik corrects the prescription permanently by changing the shape of the cornea with an excimer laser. Paragon crt molds the cornea temporarily using a flat contact lens.
