LASIK is a laser eye surgery that is performed to correct refractive errors. With LASIK eye surgery, the cornea is reshaped to make the vision clear. Astigmatism, myopia and hyperopia can be corrected by LASIK eye surgery. Cornea reshaping makes the eyes focus significantly better, and patients' visual acuity is drastically improved by this process. As with any type of surgery, there are potential long term effects associated with LASIK eye surgery.
Considerations
LASIK eye surgery's modern techniques have only been practiced since the 1990s, so any possible long term effects are still not widely understood. Researchers and scientists who study the surgery believe that there are probably no serious, permanent long term effects from LASIK eye surgery, although some people have reported otherwise. The excimer is the name of the laser used for LASIK, and has been used since the 1980s. The excimer has shown no signs of long term effects.
Reduced Night Vision
Reduced night vision or seeing "halos" around objects in dim lighting are two possible long-term effects of LASIK eye surgery. The FDA (Food and Drug Administration) warns about these possible effects. The FDA also states that some patients might not be able to drive at night after having LASIK eye surgery.
Temporary Improvement
LASIK eye surgery's vision improvements are reported to be permanent, but the FDA states that the improved vision might not last forever. The vision improvement could just be temporary, and the LASIK effects could wear off as soon as three years after the surgery. It is very common for people who underwent LASIK to still need glasses to read.
Prevention/Solution
It is very important to make sure you are an appropriate candidate for the procedure before you decide to get LASIK eye surgery. LASIK complications generally occur to people who have not been properly educated about the process and any potential outcomes or have not been properly screened.
Warning
Certain types of people should avoid LASIK eye surgery. Some examples include people who suffer from immune system diseases, individuals under eighteen years of age, people with specific types of eye diseases and women who are either nursing or pregnant.
