What is PRK versus LASIK?
PRK (Photo refractive Kerotectomy) is laser surgery to correct nearsightedness (myopia), farsightedness (hyperopia) and astigmatism. An Excimer laser beam is used to flatten the front of the cornea. The 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 the side. Next, the Excimer laser sculpts the cornea with a cool, ultraviolet light. Finally, the "flap" is returned to its original position for quick, natural recovery.
What Is Nearsightedness?
Nearsightedness (myopia) occurs when the curvature of the cornea is too steep or the eye is too long, the focus of the rays of the light that enter the eye therefore fall short of the retina. The result is blurry view of distant objects.
What Is Astigmatism?
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.
What Is Farsightedness?
Farsightedness (hyperopia) occurs when an eye is too short or the cornea is too flat. Light rays entering the eye focus behind the retina, and as a result there is blurred vision for distance as well as near objects.
Is It Covered By Insurance?
Generally it is not covered by insurance, but you need to check with your individual company.
What Are The Side Effects?
As with any treatment or operation there are risks, even though they are rare. The risks and benefits will be thoroughly explained to you by a professional staff member during your screening appointment.
How Long Will I Be Off Work?
You can have the procedure and be back to your normal day-to-day activities very quickly. Most of our patients return to work the following day. During your screening appointment we will discuss this with you so that you know your options.
Does It Really Work?
Yes! LASIK Laser Surgery is being performed around the world. Over 90% of patients who have the procedure obtain normal vision and many others are happy to lessen their dependence on spectacles and contact lenses.
