LASIK Eye Surgery

How does it work?

Types of Laser Eye Surgery

Laser eye surgery is a surgical procedure intended to reduce a person's dependency on glasses or contact lenses. There are six types of laser eye surgery. They are: LASIK (Laser Assisted In Situ Keratomileusis), PRK (Photorefractive Keratectomy), LASEK (Laser Assisted Sub-Epithelial Keratomileusis), Epi-LASEK (a slight modification of LASEK surgery) ALK (Automated Lamellar Keratoplasty), LTK (Laser Thermokeratoplasty).

LASIK eye surgery

LASIK eye surgery is the most popular laser eye surgery. In this procedure,

a flap is created in the cornea with the help of a microkeratome blade, or a laser keratome. The surgeon then corrects the shape of the medial cornea layer (called stroma) with an excimer laser. As the laser pulses, it makes a ticking sound. The laser reshapes your inner corneal layer to mimic your contact lens or glasses prescription. For precise correction, an eye-tracking device tracks your eye movements up to 4,000 times per second. The flap is replaced back in its position, which heals with time.
