You might have known about such technique of vision treatment as laser correction and its efficiency is believed to be the greatest. With assistance of some modern systems physicians are able to treat such illnesses as nearsightedness, long sight and astigmatism. Maybe the physicians West Sacramento lasik institute will propose some new solutions to current system. Persons that use laser vision treatment can be sure that the consequences of the treatment will be constant and their sight will be nice.

The history of laser vision correction

The problem of vision correction became interesting in the beginning of the 20th century. Such late improvement of that area of medicine is conditioned by the lack of needed technologies. One of the most spread methods is Fedorov's method. The instruments for these operations are actually microscopic and by usage of them doctor may perform as small incisions as he requires. After the first experimental operations were performed the scientists ascertained that these operations can do harm to the eyelens and some other parts of eye. The operation is really hazardous as it can cause some considerable results. In some conditions that may be even the complete loss of sight.

Eximer-laser vision correction

Scientists started developing some new methods utilizing principles of Fedorov's method. Doctors required to have lots of new solutions and in 1970's modern eximer laser was offered by scientists. The up to date vision treatment methods are founded precisely on eximer laser systems and they are believed to be the most effective. The laser is connected to the computer which includes some special program that accurately aims the laser beam. The basic object of carrying out of any surgical operations is to get the proper shape of the cornea. There are two the most renowned techniques that are commonly utilized nowadays: PRK photorefractive keratectomy and Lasik.

PRK method

That technique is actually widespread and it is based on usage of eximer laser in medical purposes. The importance of current system is to eliminate the unevenness of the retina by means of evaporating of its substances. This method is called non-contact as neither surgeon nor any tools contact with the face of an eye. Nevertheless PRK system has several drawbacks: some micro erosion appears during the operation and the operated person feels pain over a period of several days.

Lasik method

Eximer-laser technology is used during the performance of the operations with lasik technique. The primary experiments were performed by the scientists of Punta Gorda lasik center. During the operation definite upper layers of cornea are removed and placed in special liquid to save it. The basic instrument which is used during the applying of lasik technique is a special microsurgical tool that cuts the upper level of the cornea. The eyeball becomes open and all its sections are reachable. After the operation is over the extracted tissues ought to be attached to the eyelens. So current system may help persons who suffer from bad eyes with no incisions and sutures at all. The most renowned institution which carried out a huge amount of experiments is Lubbock lasik surgery.
