LASIK is an acronym that stands for Laser-Assisted In Situ Keratomileusis. This is one of many forms of refractive surgery that have helped millions around the world get rid of their need for glasses or contact lenses by using the power of laser technology Know more. In order to understand how is a LASIK surgery performed, it is first important to understand what a laser is and how it works. It works on the principle that a piece of tissue in the eye called the cornea is made out of proteins which are called corneal cells.
A cornea can be slightly curved, either slightly off center or curved in an unnatural fashion, which causes the eye to experience issues with clear vision. As the cornea gets slightly off center over time, it causes light to reflect off of the surface of the eye in different directions, creating blurry vision and other visual problems.
Lasik Surgery Performed
One way that the eye can get this off center shape is by use of contact lenses. These lenses actually cover part of the cornea, making the cornea slightly off center, which causes the blurry vision and other effects. By using an artificial lens in place of the contact lenses, the cornea can be corrected, making the person’s eyes free of glasses or contact lenses.
The process of getting Lasik surgery is relatively quick and straightforward. Usually, patients are advised to go home the day after their treatment and stay away from bright lights or computer screens for several weeks. It is important to follow these guidelines to ensure that the eyes heal well and do not develop any infections or irritations. After several weeks, patients can usually go back to using contact lenses, if they wish.
