Corneal Vision Correction
Vision correction procedures involving the cornea all work by altering the shape of the cornea. Examples of refractive surgery involving the cornea include LASIK and PRK (photorefractive keratectomy).
LASIK employs the precision of a laser to reshape the cornea based upon your refraction. For example, if you are nearsighted, laser vision correction procedures can reshape the corneal surface enough to neutralize your nearsightedness, allowing you to become free of glasses.
