Laser Can Assist Patients to Get Rid of Eyelens Diseases

You might have known about such method of vision correction as laser correction and its effectiveness is considered to be the greatest. With assistance of some modern methods physicians can treat such illnesses as nearsightedness, long sight and astigmatism. Maybe the scientists Opelika lasik institute will offer some new solutions to this system. The consequences of such curing operations are usually stable and do not change during the entire life.

The history of laser vision correction

The problem of vision treatment became interesting in the beginning of the 20th century. Such late developing of this field of medicine is dependent on the lack of required technologies. One of the most widespread systems is Fedorov's method. During the operation doctor utilizes some unique microsurgical instruments and performs small incision and insections on the cornea. Lately that has figured out that regardless of its efficiency current technique of vision correction implies the appearing of some unexpected side effects. Doctors recommend resort to these operations in case the situation with vision is not despairing as the operation is really complicated and risky.

Eximer-laser vision correction

Fedorov's method was widely used but it wasn't perfect so some other techniques appeared then. In the 1980's the first eximer laser was developed that had a great influence on medicine in general. That is hard to realize but modern eximer laser techniques can guarantee the safest and the most effective operations. The accurateness of laser beam which carries out some actions on the surface of the eye is provided by computer. The main object of carrying out of any surgical operations is to get the proper 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 initial application of eximer laser in medic purposes. Laser beam which is aimed on the tissues of the retina evaporates part of them and the form of the eyeball become appropriate. Scientists relate this method to the non-contact methods as all the actions are carried out just by means of laser beam. Nevertheless PRK system has got several disadvantages: some micro erosion appears during the operation and the patient feels pain over a period of a week.

Lasik method

This technique is the complex of microsurgical influence and eximer-laser technology. The primary experiments were performed by the scientists of Brooklyn lasik center. It assists to save the structure of retina tissues which brings an opportunity to avoid the appearing of sensation of pain during the rehabilitation after operation. The most beneficial is that the upper tissues wouldn't be damaged and there will no pain during the period of the rehabilitation. So other parts of eyeball are now reachable for the laser beam. When the operation is over the detached tissues should be attached to the eyeball. The main advantage is that laser beam has got considerably greater accurateness if matched with any other surgical tools. There are many centers which try to develop nicer methods of vision correction and maybe the most renowned of them is Herndon lasik surgery.
