You might have heart about such technique of vision correction as laser correction and its efficiency is considered to be the highest. With some modern systems such serious eye disease as astigmatism, nearsightedness and long vision can be treated. Such techniques are being developed in New Britain lasik institute. The consequences of such treating operations are commonly stable and do not modify during the whole lifetime.

The history of laser vision correction

The problem of sight treatment became being reviewed in the beginning of the 20th century. Scientists began to develop some newest technologies to discover eyeball more appropriately. The famous Soviet doctor Fedorov invented some methods then. The instruments for these operations are actually microscopic and by usage of them surgeon may perform as little incisions as he needs. Lately it has figured out that regardless of its efficiency current method of vision treatment implies the appearing of several unpleasant side effects. The operation is rather hazardous as it can produce some serious consequences. In some conditions it can be even the absolute loss of sight.

Eximer-laser vision correction

Doctors began developing some new techniques using principles of Fedorov's method. Doctors wanted to have some new solutions and in 1980's the newest eximer laser was proposed by scientists. That is hard to believe but the newest eximer laser methods can guarantee the safest and the most efficient operations. The accurateness of laser beam that carries out some operations on the surface of the eyeball is provided by computer. The basic cause of many problems related to vision is some curvature of tissues of the eyeball and eyelens. Operations which demand the usage of laser system are truly difficult and there are some modern techniques that can propose the required accurateness.

PRK method

This method is the first case of usage of eximer laser in medical purposes. To correct the form of retina the laser beam which has high temperature evaporates some excess parts of eyeball. The other benefit of current technique is that neither instrument nor surgeon touch the surface of the eye as the laser beam is utilized. Nevertheless PRK system has got some drawbacks: some micro erosion appears during the operation and the patient feels pain over a period of several days.

Lasik method

This method is the newest one as there is a complex of mechanical and thermal tools. It was firstly used in Fort Myers lasik center. During the operation some upper pats of cornea are removed and placed in special liquid to save it. The most advantageous is that the upper layer wouldn't be injured and there will no pain during the period of the rehabilitation. So other sections of eyelens are now reachable for the laser beam. The other process which demands the greatest level of preciseness is to set the extracted sections to their locations. So current method can assist persons who suffer from bad eyes with no incisions and sutures at all. There are lots of establishments that try to develop better methods of sight treatment and probably the most renowned of them is Wilmington lasik surgery.
