I have worn glasses for my most of my life. In high-school I wore contact lenses. The idea of laser eye surgery always scared me and confused me as a kid. I began to ponder what is the procedure behind laser eye surgery and what was the science behind the surgery. I wonder how effective is the surgery. Laser eye surgery is when a thin layer that is called the cornea is removed in order to perfect the shape of the cornea. The surgery is supposed to correct the vision to be 20/20. How could this be true? I pondered if there were results where it did not work out for patients that had laser eye surgery. The first source I read said that the first surgery “was first performed experimentally on a blind human eye in 1981 in the US and first performed on a sighted eye in 1986 in Germany. We therefore have over 25 years of clinical experience with PRK laser vision correction eye surgery.” (1)From the results of this the surgery was successful. There was another study done where the patients were followed up from 16 years later from when they had the surgery and it was found that the majority of the patients had 20/20 vision and could see better without glasses. It makes it seem like it does work but what about the side effects of the surgery? The most common side effects are temporary discomfort and flap complications. In a more recent source it says that “more than 40 percent of those who did not experience visual symptoms before the surgery reported experiencing one or more new visual symptoms, such as seeing glare or halos around objects.” (2)In other studies, it has been successful without having those side effects. What is laser eye surgery broken down by science? According to … it says that “LASIK is performed with an ultraviolet (UV) excimer laser. Excimer stands for excited dimer, an excited, unstable molecule of an “inert” gas and a halogen—argon and fluorine. This short-lived molecule dissociates promptly with the emission of a UV photon of a particular frequency.”(3) I have seen photos and videos on how the process is done and after researching online I have found that the side effects are deal able. I believe the surgery does work in doing its job to improve someone’s eyesight. The only negative thing could happen is the flap complications that can be fixed.
