You might have known about such method of vision treatment as laser correction and its efficiency is believed to be the greatest. With some newest systems such serious eye disease as astigmatism, nearsightedness and long sight can be cured. Such methods are being developed in Russellville lasik institute. The most significant benefit is that the vision treatment is stable and the vision won't become worse in future.

The history of laser vision correction

The initial phase of the improvement of laser correction systems began in the middle of the 20th century. Ophthalmologists started to develop some modern systems to study retina more appropriately. One of the most widespread systems is Fedorov's method. During the operation surgeon uses some unique microsurgical instruments and performs small incision and insections on the cornea. Recently that has turned out that regardless of its efficiency current technique of vision correction implies the appearing of several unpleasant side effects. Doctors recommend not to use these operations if the situation with vision is not despairing as the operation is actually complicated and dangerous.

Eximer-laser vision correction

Surely the developing of some modern methods of sight correction was going on. In the 1980's the first eximer laser was developed and it had a huge impact on medicine in all its directions. Today physicians announce that methods which use eximer lasers as base are actually safe and their effectiveness is fabulous. The laser is connected to the computer which includes some special system that accurately aims the laser beam. The basic origin of many troubles related to vision is some curvature of tissues of the eyeball and eyelens. There are two the most renowned methods that are frequently used nowadays: PRK photorefractive keratectomy and Lasik.

PRK method

The uniqueness of this technique is that it is the initial application of eximer laser in medicine. The importance of current method is to eliminate the unevenness of the cornea by usage of evaporating of its substances. The other benefit of this method is that neither tools nor surgeon touch the face of the eye as the laser beam is used. However PRK method has got some drawbacks: some micro erosion appears during the operation and the operated person feels pain over a period of a week.

Lasik method

Eximer-laser technology is used during the performance of the operations with lasik method. The initial tests were carried out by the scientists of Columbia lasik center. During the operation definite upper pats of cornea are detached and placed in some liquid to save it. The basic instrument that is used during the applying of lasik method is a special microsurgical instrument that cuts the upper level of the retina. So other sections of eyeball are now obtainable for the laser beam. Another action which requires the highest level of preciseness is to set the extracted parts to their places. So this system may assist persons who suffer from bad vision with no incisions and sutures at all. Every year lots of ophthalmologists from all over the globe gather in Mc Lean lasik surgery to define some problems and offer resolutions related to laser vision correction.
