Lasik Eye Surgery Information

Glasses have been popular since the end of 13th century

, while the contact lenses went over big since the late 1970s, and recently a newly emerged eyesight assistance comes into being and has become a main way for vision correction. That is Lasik eye surgery, the abbreviation of Laser-Assisted-Epithelial Keratomileusis.

Lasik, performed by ophthalmologists with a laser, is a type of refractive surgery for correcting myopia, hyperopia and astigmatism. Owing to its specific features, it is more favored by many to PRK, ASA, and or so.

Lasik is different from another 'Lasik' with its full name of Laser-Assisted-In-Situ Keratomileusis. What we mention here is superior for its treatment for people with thicker corneas and is of higher success rates.

The first Lasik surgery is firstly performed at the Massachusetts Eye and Ear Infirmary in the USA in 1996, and since then it widely spreads all over the globe, especially in the United Kingdom. Features of its popularity include that little time will be taken for the procedure, the patients feel rarely uncomfortable and they can go for their normal lives right after the surgery.

Then comes to the question how dose a Lasik surgery perform? Firstly, the surgeon will apply a spring-like tackle to make eyes widely open and certain anaesthetic drops are dripped into the eyes; secondly, the surgeon will create a flap with a laser, controlled by a computer, on the top of the cornea so that he or she can reshape the cornea (eyesight problems is caused by the abnormal shape of cornea). Thirdly, during the reshaping procedure, the surgeon will apply an excimer laser to restore the cornea to its original position and a bandage contact lens is applied; fourthly, the flap is replaced.

Usually many Lasik eye surgery patients may experience immediate improved vision, although it can take up to six month for vision to stabilize.

However, the drawback is that people over 40 years old who undergo Lasik eye surgeries may not abandon eyeglasses, because their natural lens can not focus quickly enough between far and distance objects. We just expect that in the future the surgery can be improved to solve this question, helping people with presbyopia abandon glasses.

One thing needs reminding is that anyone being willing to have a Lasik should consult with his or her eye doctor, to make sure whether the Lasik is suitable for him or her. Never take a risk of damaging your eyes.
