Common Vision Problems Corrected by LASIK
Nearsighted individuals typically have problems seeing well at a distance and are forced to wear glasses or contact lenses. The nearsighted eye is usually longer than a normal eye and its cornea may also be steeper. Therefore, when light passes through the cornea and lens, it is focused in front of the retina. This will make distant images appear blurred. LASIK and PRK are both solutions for Myopia.
Farsighted individuals typically develop problems reading up close before the age of 40. The farsighted eye is usually slightly shorter than a normal eye and may have a flatter cornea. Thus, the light of distant objects focuses behind the retina unless the natural lens can compensate fully. Near objects require even greater focusing power to be seen clearly and therefore blur more easily. LASIK or PRK monovision, refractive lens exchange (RLE) and cataract surgery with the insertion of a multifocal lens are all solutions for Hyperopia.
Asymmetric steepening of the cornea causes light to be focused unevenly, the main optical problem in astigmatism. To individuals with uncorrected astigmatism, images may look blurry or shadowed. Astigmatism can accompany any form of refractive error and is very common. Solutions for astigmatism are LASIK, PRK, corneal relaxing incisions and Toric lens implants.
Presbyopia is a condition that typically becomes noticeable for most people around age 40 to 45. In children and young adults, the lens inside the eye can easily focus on distant and near objects. With age, the lens loses its ability to change focus adequately.
The lens inside the eye and its supporting structures lose the ability to make the lens longer during close vision effort. To compensate, affected individuals usually find that holding reading material further away makes the image clearer. Ultimately, aids such as reading glasses or bifocals are typically needed by the mid-40s. Surgical solutions for presbyopia include monovision LASIK or PRK, cataract or refractive lens exchange with a multi-focal IOL implant.
