Laser Vision Correction
LASIK - Laser in situ keratomileusis
LASIK is actually a two-step process. First, a flap of corneal tissue must be created and then folded back. The cornea is the transparent dome-like structure that covers the iris and pupil of your eye. By creating a flap in the cornea, the surgeon is able to perform the laser vision correction treatment on the inner layer of the cornea, which practically eliminates any patient discomfort and allows for a rapid visual recovery.
PRK - Photorefractive keratectomy
PRK uses the excimer laser to reshape an area on the surface of the eye (cornea). The cool beam of light gently pulses to remove microscopic amounts of tissue allowing images to be more sharply focused. The procedure typically removes about the thickness of one human hair from the eye. With PRK no flap is created. PRK is the preferred procedure for patients with thin corneas.
