Nowadays laser correction is believed to be one of the most progressive tendencies in the field of up to date ophthalmology. As in any other field of medicine doctors try to utilize a lot of modern technologies and thanks to it we are able to cure even such illnesses as astigmatism. These techniques are being improved in San Jose lasik institute. Persons who use laser vision treatment can be assured that the results of the operation would be constant and their vision 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 developing of that area of medicine is dependent on the lack of needed technologies. The great impact on the developing of vision treatment medicine had the method proposed by Fedorov. During the operation doctor uses some special microsurgical tools and makes small incision and insections on the cornea. Of course such operations are truly difficult to go through and even some insignificant error may bring lots of bad consequences. The retina goes through definite mechanical actions and the patient may have some worsening of the sight or in some instances it can be the absolute loss of vision.

Eximer-laser vision correction

Of course the developing of some new techniques of sight correction was going on. In the 1970's the first eximer laser was developed and it had a huge impact on medicine in all its directions. That is hard to realize but the newest eximer laser methods can provide the safest and the most efficient operations. The accurateness of laser beam that performs some actions on the surface of the eye is provided by computer. The main purpose of performing of any surgical operations is to get the normal shape of the cornea. There are two the most renowned methods that are frequently used nowadays: PRK photorefractive keratectomy and Lasik.

PRK method

The uniqueness of this technique is that it is the first application of eximer laser in medicine. The essence of this system is to eliminate the unevenness of the cornea by usage of evaporating of its substances. Scientists relate this method to the non-contact techniques as all the actions are performed just by means of laser beam. This operation is considered to be truly painful for the patient as the cornea is being considerably damaged.

Lasik method

Current technique is the complex of microsurgical actions and eximer-laser technology. The primary tests were carried out by the doctors of Des Plaines lasik center. During the operation some upper layers of cornea are removed and placed in some liquid to save it. The most advantageous is that the upper tissues wouldn't be damaged and there will no pain during the period of the rehabilitation. The eyelens becomes open and all its sections are reachable. After the operation is over the extracted tissues ought to be attached to the eyelens. So this system may help people that suffer from bad eyes with no incisions and sutures at all. Every year lots of ophthalmologists from all over the world gather in Fairfax lasik surgery to define some troubles and propose solutions connected to laser sight correction.
