Laser vision correction refers to surgical procedures that use laser technology to reshape the cornea of the eye, with the goal of correcting common vision problems such as:

The most common types of laser vision correction include:

1. PRK (Photorefractive Keratectomy): In PRK, the outer layer of the cornea (epithelium) is completely removed before the laser is applied to reshape the cornea. The epithelium regenerates naturally over time.

2. LASIK (Laser-Assisted In Situ Keratomileusis): During LASIK, a laser is used to create a thin flap on the cornea, which is then lifted to allow the reshaping of the underlying corneal tissue. The flap is then repositioned.

3. LASEK (Laser Epithelial Keratomileusis): LASEK is a variation of PRK where the surgeon creates a thinner flap of epithelial tissue, which is then lifted and replaced after the laser treatment.
