Nowadays laser correction is considered to be one of the most progressive trends in the field of up to date ophthalmology. With help of some up to date systems doctors are able to cure such illnesses as nearsightedness, long sight and astigmatism. Such techniques are being improved in Florence lasik institute. The most significant benefit is that the vision correction is constant and the vision won't get worse in future.

The history of laser vision correction

The history of laser treatment systems started in the the beginning of the 1960's in different states simultaneously. Such late improvement of that area of medicine is conditioned by the shortage of required technologies. The significant impact on the improvement of sight treatment medicine had the technique offered by Fedorov. During the operation surgeon utilizes some special microsurgical instruments and makes small incision and insections on the retina. After the initial test operations were performed the doctors ascertained that these operations can do harm to the eyeball and several other parts of eye. Doctors recommend resort to such operations in case the situation with sight is not hopeless as the operation is actually complicated and dangerous.

Eximer-laser vision correction

Fedorov's technique was broadly used but it wasn't perfect so some other methods appeared then. Physicians wanted to get some modern solutions and in 1970's modern eximer laser was proposed by scientists. Today physicians say that techniques that utilize eximer lasers as basis are really safe and their effectiveness is fabulous. Laser beam is controlled by some special computer program of reshaping of the retina. As the shape of the eyelens is modified, some normal features can be rehabilitated so beams are being aimed on the retina appropriately. There are two the most renowned methods that are commonly used nowadays: PRK photorefractive keratectomy and Lasik.

PRK method

That method is really frequently used and it is based on use of eximer laser in medical objectives. Laser beam that is aimed on the tissues of the cornea evaporates part of them and the form of the eyelens become proper. Physicians relate this technique to the non-contact methods as all the actions are carried out just by means of laser beam. Nevertheless PRK system 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 utilized during the carrying out the operations with lasik technique. Physicians from Lawrenceville lasik center tested it. During the operation some upper layers of retina are detached and placed in special liquid to save it. The most advantageous is that the upper tissues wouldn't be injured and there will no pain during the process of the rehabilitation. It is not so difficult to correct some parts of inner structure of the eyeball. When the operation is over the detached tissues should be attached to the eyelens. The computer program can't do any errors unlike the surgeon with surgical tools. There are lots of centers which attempt to develop better techniques of vision correction and probably the most renowned of them is Goldsboro lasik surgery.
