Both LASIK and PRK are intended to correct vision, but their approaches differ. During a LASIK procedure, a thin flap in the cornea is created, allowing the doctor to have access to the inner tissues for laser reshaping. After reshaping, the flap seals itself shut and heals quickly. It is required that patients have healthy corneas. On the other hand, a flap is not necessary for PRK. During the procedure, the laser is used on the surface of the cornea, not under a flap. Both surgeries are excellent vision correction options, and it is best to speak to our doctors about which procedure is right for you.
