welcome to disease section for myopia 

The eye is our organ of sight. The eye has a number of components which include but are not limited to the cornea, iris, pupil, lens, retina, macula, optic nerve, choroid and vitreous.

Photorefractive Keratectomy (PRK) is a type of refractive surgery to correct myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. The thin outer layer of your cornea called epithelium is removed before reshaping the underlying corneal tissue with an excimer laser. The epithelium heals itself and grows back over the corneal surface within a few days after the surgery.
