The cornea is reshaped to correct myopia, hypermetropia, astigmatism and presbyopia using a laser which removes corneal tissue with precision. Millions of people around the world have undergone laser eye surgery to correct their eyesight.
There are different options available: LASIK, LASEK and PRK/TransPRK
- LASIK (Laser-Assisted In-situ Keratomileusis)
This is performed in two stages with two different lasers. One to create a thin flap on the surface of the cornea, and another to reshape the cornea underneath. The protective flap is then replaced back over the treated area.
- LASEK (Laser-Assisted Sub-Epithelial Keratomileusis)
The clear skin (epithelium) covering the cornea is loosened and moved aside to allow the laser to reshape the cornea underneath. The skin is then rolled over and replaced.
- PRK/TransPRK (Photorefractive Keratectomy)
This involves removal of the skin (epithelium) which is then allowed to grow back naturally.
