Approved for Astronauts Did you know that LASIK surgery is approved by NASA? Having 20/20 vision is required to be an astronaut. See how our “best of the best” technology became approved for the most demanding job there is. What is LASIK? LASIK is an acronym for Laser-Assisted In-Situ Keratomileusis, a procedure that uses a laser to reshape the cornea and correct refractive error, the failure of the eye to properly focus light on the retina. There are three common types of refractive error that can be treated with LASIK eye surgery: Refractive Errors Treatable with LASIK Nearsightedness Also known as “myopia”, nearsightedness occurs as a result of the eye growing too long from front to back, or from the cornea being too curved. This causes the light entering the eye to be incorrectly focused, and results in blurry vision. Patients with nearsightedness are able to see up-close objects well, but have difficulty seeing objects in the distance. Nearsightedness is very common and more than 3 million cases are reported each year. Farsightedness Hyperopia, also referred to as “farsightedness” occurs when the eye is too short, or the cornea develops improperly, and lacks curvature. This flat cornea causes incoming light to be bent improperly, resulting in nearby objects appearing blurry, while distant objects look normal. Farsightedness is also very common, with around 3 million new cases reported each year. Astigmatism Astigmatism is also a result of a defect in the eye or shape of the lens. Astigmatism often occurs in conjunction with either nearsightedness or farsightedness. Patients with astigmatism have an eye that is slightly football-shaped, which prevents the incoming light from being focused. This results in vision being blurred at all distances. How Does LASIK Work? LASIK eye surgery corrects vision by reshaping the cornea, so that light rays focus more precisely on the retina, thereby reducing or eliminating refractive errors. There is typically little or no post-operative discomfort after LASIK surgery. Recovery is fast and complications are rare if your procedure is performed by an experienced LASIK surgeon utilizing the best available technology. The LASIK Procedure The first step in LASIK eye surgery is to create a corneal flap. A very fine layer of the outer corneal surface is incised with a laser or microkeratome and folded back to expose the stroma, the middle corneal layer. The second step of LASIK surgery is to use a laser to remove microscopic amounts of tissue to reshape the cornea. Lastly, the flap is returned to its original position and reseals itself. What is iLasik? Traditionally the LASIK flap had been made with an instrument with an oscillating blade. Vision correction was achieved by the surgeon manually entering prescription information into an excimer laser and delivering the treatment under the LASIK flap. Two major advances in technology: the IntraLase laser to create a blade-free flap and CustomVue technology to correct higher order aberrations, so revolutionized the LASIK procedure that the combination has been designated iLASIK. iLASIK still maintains the two basic steps of the older LASIK procedure but is the manifestation of major improvements in both steps. The evolution of LASIK into the iLASIK procedure utilizing a wavefront analyzer and two separate lasers: one to make the flap and one to perform the vision correction, has made a good procedure even better and safer. LASIK Technology LASIK technology has evolved over the years. iLasik™ is a new brand of LASIK eye surgery that has been pioneered and perfected by AMO/VISX and IntraLase technology. All branches of the U.S. military and NASA recently approved LASIK for all their servicemen and women, thanks to studies using the iLasik™ technology. NASA approved the LASIK procedure for its astronauts following review of extensive military clinical data, which showed the use of the two lasers (IntraLase and Wavefront) provides superior safety and vision as compared to earlier forms of the procedure. Our LASIK Durham / Raleigh facility offers the latest LASIK technology available to date.
