Types of Laser Vision Correction
With continually advancing technology and techniques, laser vision correction is becoming available to more and more people on an almost daily basis. Although LASIK is the most common form of laser vision correction, there are many other variations, and which one is best for you depends on the anatomy of your eye and other factors. To help you better understand the main variations on the procedure of laser vision correction, we offer this brief guide.
LASIK stands for Laser-Assisted In-situ Keratomileusis, and it is the most commonly practiced form of laser vision correction. In traditional LASIK surgery, a flap of the cornea is created to allow the VISX Excimer laser to reshape the cornea to properly focus light rays on the retina. LASIK corrects moderate myopia (nearsightedness), hyperopia (farsightedness), and astigmatism (blurriness independent of distance) in most patients.
Custom LASIK is a variation on the LASIK procedure that utilizes more advanced technology in mapping the eye to improve the results of the LASIK procedure for some patients. With Custom LASIK, the VISX CustomVue system uses WaveFront technology to more accurately map the precise refractive error in the eye prior to treatment. This treatment allows people who were not previously candidates for LASIK due to the severity of their astigmatism to receive laser vision correction. According to clinical studies, over 95% of people who receive Custom LASIK receive 20/40 vision or better as a result.
PRK (Photorefractive Keratectomy) is a procedure that predates LASIK, and its practice declined for a period of time. However, recent technological advances have improved PRK and LASIK simultaneously, and PRK has been growing in popularity again as an option for treating people not able to have LASIK. In LASIK, a flap is created in the cornea, and the laser vision correction is performed on a surface in the middle of the cornea. In PRK, however, the laser vision correction is performed directly on the surface of the cornea without the creation of a flap. This makes it an option for people who have thin corneas or corneas otherwise unsuited for LASIK.
