Today laser correction is considered to be one of the most progressive tendencies in the area of up to date ophthalmology. As in any other area of medicine doctors attempt to apply a lot of newest systems and thanks to it we can treat even such diseases as astigmatism. These methods are being developed in Modesto lasik institute. People that use laser vision treatment can be sure that the results of the operation would be constant and their sight would be nice.
The history of laser vision correction
The history of laser correction methods began in the early 1960's in different countries at the same time. Such late improvement of that field of medicine is dependent on the shortage of needed technologies. One of the most widespread systems is Fedorov's method. During the operation doctor utilizes some unique microsurgical instruments and makes little incision and insections on the cornea. After the first test operations were carried out the doctors knew that these operations may do harm to the eyeball and some other sections of eye. Physicians recommend resort to such operations in case the situation with sight is not despairing as the operation is really complex and risky.
Eximer-laser vision correction
Fedorov's technique was broadly utilized but it wasn't perfect so some other techniques appeared then. Physicians required to get some modern solutions and in 1970's modern eximer laser was offered by scientists. Today doctors say that techniques which utilize eximer lasers as basis are really safe and their efficiency is fabulous. The laser is connected to the computer that includes some special system which precisely aims the laser beam. The main object of performing of any surgical operations is to get the proper shape of the retina. Operations which demand the use of laser system are really complicated and there are some modern techniques which can propose the needed accurateness.
PRK method
That technique is really widespread and it is founded on use of eximer laser in medical objectives. Laser beam which is aimed on the tissues of the retina evaporates some of them and the form of the eyelens become proper. Another benefit of current method is that neither instrument nor surgeon touch the surface of the eyelens as the laser beam is used. Such operation is considered to be truly painful for the patient as the cornea is being seriously damaged.
