An Explanation Of Lasik Surgery

This world is filled with individuals who are born with perfect 20/20 vision and the others with impaired vision

. Within the latter group, there are people who have difficulty in seeing either close things or distance objects. For these folks, prescription eyeglasses and contact lenses are the most common solutions. These devices for lifelong usage often cost hundreds of dollars. It is common to replace broken or old eyeglasses or buy new packets of contact lenses. During a long time, glasses and contact lenses were the only options available for patients. But currently, they are no longer the only solutions.

Using eyeglasses or contact lenses on a regular basis is sometimes quite bothersome, not to say those necessary expense. A good and popular alternative to these traditional options is LASIK eye surgery, which stands for a laser in situ keratomileusis. Like other forms of laser eye surgeries, LASIK also reshapes a patients corneal surface using a laser. In detail, some tissues will be removed by the laser underneath the corneal flap which has been cut in advance. By removing unwanted tissues, the corneal curvature can be changed. As a result, the corrected cornea will be able again to focus light properly. Thus the patients need for glasses or contact lenses can be reduced.

It takes more time to get some details of LASIK procedure. As the transparent covering of the eye, the cornea is the essential part that is responsible for focusing light entering the eye. LASIK was then first created by Ioannis Pallikaris in 1991 to reshape an irregular cornea. Using a microkeratome, the surgeon will create a precise, thin hinged corneal flap, under which some corneal tissues will then be cut. Different forms of vision problems require the surgeon to reshape the cornea in specific patterns. Eventually, the flap will be placed back without using any sutures.
