Lasik Eye Surgery 101
Lasik eye surgery is a procedure that works to correct various vision troubles that people might be experiencing. If done properly, the patient will no longer have to wear glasses or contacts. There are various types of lasers that the operating surgeon may utilize and it depends on the visual problems that the patient might have.
These various methods include; Lasik, Lasek, PRK, ALK, and LTK.
Lasik
Lasik is apparently the more popular type of laser that is utilized and is the main reason why several individuals when talking about this operation use its name. This is really a nickname that stands for laser assisted in situ keratomileusis. This method is utilized by the surgeon to get rid of a part of the corneal tissue. This in turn will serve to remold the cornea and improve eye problems from astigmatism, hyperopia, and myopia.
Lasek
This type of laser stands for laser epithelial keratomileusis. This operation is close to that of Lasik except that the operating surgeon will pull off a much smaller piece of the cornea. This is utilized for people who have highly thin corneas and are not eligible to utilize the Lasik process. This procedure also have fewer risk and is less invasive.
PRK
This type of method used to be the more common operation that came before Lasik. But over the numerous years it has been substituted due to the positive effects from Lasik surgery. Individuals that have low to medium refractive mistakes will usually select the PRK. During this process, the surgeon will polish off a small layer of the cornea and will not substitute it. Rather, the cornea will rectify itself after a certain duration of time. People who choose this surgery will discover the beneficial effects over a few months time as the cornea heals.
ALK
Automated Lamellar Keratoplasty is most often used when addressing mild forms of farsightedness and advanced forms of nearsightedness. The surgeon will cut the flap of the cornea and utilize a microkeratome to remove any material underneath the flap.
LTK
Laser thermakeratoplasty is one of the latest processes that is being used to care for astigmatism and farsightedness. The heat that emanates from the laser beam will shrink and remold the cornea in place of removing anything. This aids the patient to heal much faster than normal surgery and is less invasive. Regrettably the effects from this operation do not last as long.
