Now the refractive surgery procedure performed by ophthalmologists worldwide, LASIK (Laser in-situ Keratomileusis) corrects nearsightedness, farsightedness, and astigmatism. During the brief procedure, a thin layer of the cornea is lifted, creating a"flap" that stays connected on one side. The excimer laser then reshapes the cornea with a cool, ultraviolet light. The"flap" is returned to its original position for a quick, natural recovery.
Sub-Bowman's Keratomileusis (SBK) is the most recent or 4th generation laser vision correction. IntraLase Method (blade-free LASIK) uses the ultra-fast FS (femtosecond) laser in the first step to create the corneal flap. According to research by Capt. Steven C. Schallhorn, US Navy (Ret.), the blade-free method virtually eliminates almost all of the severe, sight-threatening LASIK complications related to the hand-held microkeratome blade that was historically used to create the corneal flap. The accuracy of the femtosecond laser allows the physician to treat patients with thinner corneas. The IntraLase FS laser also provides an optimal corneal surface below the flap, allowing better visual outcomes from the second step of the procedure. This is the only LASIK method approved by the military and NASA for aviators and astronauts.
In nearsightedness (myopia), the curvature of the cornea is too steep, causing light rays to focus short of the retina. The result is a blurry view of distant objects.
Astigmatism can exist alone or in combination with nearsightedness or farsightedness. With this condition your cornea is oval-shaped like a football, instead of round, causing distortion when the eye tries to focus.
Farsightedness (hyperopia) occurs when the curvature of the cornea is too flat and light rays entering the eye focus behind the retina, resulting in a blurred image of near objects.
Generally, it is not covered by insurance, but we recommend that patients check with their individual insurance company. The fee may be used as a tax deduction and also qualifies for corporate flexible spending plans for out-of-pocket medical expenses.
No, the actual laser procedure does not hurt. With LASIK, some patients do experience discomfort for several hours after the procedure, which gradually dissipates and virtually disappears by the next day.
As with any treatment or procedure, there are risks, even though they are rare. The risks and benefits will be thoroughly explained to the patient by a professional staff member during the pre-operative evaluation and again by Dr. Swan or Dr. Shin prior to the procedure.
You can have the procedure and be back to your normal day-to-day activities very quickly. Most patients return to work the day after the procedure. During the screening appointment, we will discuss this with you so that you know your options.
YES! Over 2 million laser vision correction procedures have been performed around the world. The majority of our patients who have had SBK LASIK or ASA are able to function comfortably without glasses or contact lenses, except for reading glasses in those over 40.
