Top Ten FAQ's
Q: What is PRK & Lasik?
A: PRK (Photorefractive Keratectomy) is laser surgery to correct nearsightedness (myopia), farsightedness (hyperopia) and astigmatism. An Excimer laser beam is used to flatten the front of the cornea. A laser beam removes small amounts of tissue from the front of the cornea. This differs from RK, which uses a knife to make radial incisions, using a knife around the center of the cornea.

With the Lasik procedure, a thin layer of the cornea is lifted to create a "flap" that stays connected on one side. Next the Excimer laser sculpts the cornea with a cool, ultraviolet light. Finally, the flap is returned to its original position for a quick, natural recovery.

Q: What is nearsightedness?
A: Nearsightedness (myopia) is when the curvature of the cornea is too steep, the focus of the rays of light that enter the eye fall short of the retina. The result is a blurry view of distant objects.

Q: What is astigmatism?
A: Astigmatism can exist alone or in combination with nearsightedness or farsightedness. With this condition, your eye becomes oval-shaped like a football instead of round, causing distortion when the eye tries to focus.

Q: What is farsightedness?
A: Farsightedness (hyperopia) occurs when an eye is too short for the for the cornea's curvature. Light rays entering the eye focus behind the retina, and as a result a blurry image is produced.
