Today laser treatment is believed to be one of the most progressive tendencies in the area of modern ophthalmology. With lots of modern systems such significant eye illnesses as astigmatism, nearsightedness and long sight can be treated. Probably the scientists West Sacramento lasik institute will propose some modern solutions to current system. People who use laser vision correction can be sure that the consequences of the operation would be constant and their sight will be normal.



The history of laser vision correction

The issue of sight correction became interesting in the beginning of the 20th century. Ophthalmologists started to develop some modern technologies to study retina more appropriately. One of the most spread systems is Fedorov's method. During the operation surgeon utilizes some special microsurgical instruments and performs small incision and insections on the retina. Lately that has turned out that regardless of its efficiency this method of vision treatment implies the appearing of several unpleasant side effects. The retina goes through the mechanical actions and the operated person may get some worsening of the vision or in rare cases it can be the absolute loss of sight.

Eximer-laser vision correction

Surely the improvement of some new techniques of vision treatment was going on. In the 1970's there was a great invention that affected this area considerably ? eximer laser. Today physicians say that techniques which utilize eximer lasers as base are really safe and their efficiency is fabulous. Laser beam is driven by some special computer system of reshaping of the retina. The main cause of lots of problems related to eyes is some curvature of tissues of the eyeball and eyelens. Operations which demand the usage of laser system are really complicated and there are some newest techniques that may propose the required accurateness.

PRK method

The uniqueness of this technique is that it is the initial application of eximer laser in medicine. Laser beam that is focused on the tissues of the retina evaporates some of them and the form of the eyeball become proper. This method is called non-contact as neither surgeon nor any tools contact with the surface of an eye. This operation is believed to be truly painful for the patient as the retina is being seriously damaged.

Lasik method

Current method is the combination of microsurgical actions and eximer-laser system. The primary tests were performed by the doctors of Ann Arbor lasik center. The upper substances of the eyelens are detached and saved by means of some organic liquids. The main tool that is utilized during the applying of lasik method is a special microsurgical tool which cuts the upper part of the cornea. That is not so difficult to correct some sections of inner structure of the eyelens. After the operation is over the detached tissues should be attached to the eyeball. The computer program can't do any mistakes unlike the doctor with surgical instruments. The most famous institution which performed a huge amount of experiments is Spring lasik surgery.
