If you have a refractive error, such as nearsightedness (myopia), farsightedness (hyperopia), or astigmatism, refractive surgery is a method for correcting or improving your vision. This surgical procedure is used to adjust you eye's focusing ability by reshaping the cornea. The most widely performed type of surgery is LASIK (laser-assisted in situ keratomileusis), where a laser is used to reshape the cornea.
For people who are nearsighted, certain refractive surgery techniques will reduce the curvature of a cornea that is too steep so that the eye's focusing power is lessened. Images that are focused in front of the retina, due to a longer eye or steep corneal curve, will be closer or directly onto the retina after surgery.
Astigmatism can be corrected with refractive surgery techniques that selectively reshape portions of an irregular cornea to make it smooth and symmetrical. The result is that images focus clearly on the retina rather than being distorted due to light scattering through an irregularly shaped cornea.
Farsighted people will have refractive surgery procedures that achieve a steeper cornea to increase the eye's focusing power. Images that are focused beyond the retina, due to a short eye or flat cornea, will be pulled closer to or directly onto the retina after surgery.
There is no universally-accepted, best method for correcting refractive errors. Find out if you are a candidate for this life-changing procedure by scheduling a personal consultation with Dr. Pak.
