What is LASIK
In today’s tech-savvy world, many people have been considering LASIK to correct their eyesight. As the leading form of technology trusted by a variety of patients, LASIK has benefited millions of people around the world. Growing in popularity, this quick and simple procedure provides lasting results. LASIK surgery is where a laser is used to delicately burn away tissue surrounding the cornea. This precise, controlled removal process results in the re-shaping of the cornea, altering its focusing power. Cornea tissue is removed because it directly impacts eyesight strength. Much like the lens of a camera, the cornea is the part of the eye that is responsible for focusing light to project an image on the retina.
The term “refraction” refers to the bending and focusing of light. As a result, refractive errors are present when problems arise with the focusing strength of the eye. Refractive errors, or imperfections, can be categorized into three primary types: myopia, hyperopia and astigmatism. Myopia refers to individuals suffering from nearsightedness, which is where people have difficulties perceiving distant objects as clearly as objects in close proximity. However, hyperopia, also known as farsightedness, is when people have more trouble viewing nearby objects as opposed to items placed at a far-away distance. Lastly, astigmatism indicates that the image reflected on the retina is distorted, due to irregularities in the cornea. You should have a general perception of the concept of LASIK and start considering if it would be for you.
Risks of LASIK
As with any surgical procedure, there are potential risks associated with LASIK correction. To begin with, any alterations made to the cornea are irreversible once the procedure has been completed. Aside from minor side effects, including glare, halos, double vision and dry eyes, two common problems that may arise are under-corrections and over-corrections. These errors can occur if too little tissue is removed from the eye, or if too much tissue is taken away. In both circumstances, it may be necessary to undergo another refractive procedure within a year in order to obtain optimal vision results.
Benefits of LASIK
Nevertheless, despite the potential side effects, there are many benefits associated with LASIK. The procedure has about a 90 percent success rate, with patients achieving their desired vision after surgery. Best of all, there is very little pain involved with LASIK, and eyesight is corrected almost immediately, or even by the day after the process is completed. Furthermore, no bandages or stitches are needed at the end of surgery. Once patients undergo LASIK treatment, touch-ups or additional adjustments can always be made for years to come in order to further enhance eyesight.
How you approach LASIK is dependent on doctor review. While this article briefly detailed the concept, risks and benefits – only speaking to your doctor will provide the best advantage and next step process. Is LASIK right for you? You may decide with your doctor it is the perfect remedy.
