There are lots of methods of vision correction today but not all of them are really helpful and efficient. The most efficient system is laser operations. With help of some up to date methods doctors can cure such illnesses as nearsightedness, long sight and astigmatism. Doctor John Zorn announced that Santa Cruz lasik institute has an opportunity to improve these techniques a lot. The results of such treating courses are commonly stable and do not modify during the entire lifetime.

The history of laser vision correction

The issue of sight treatment became interesting in the beginning of the 20th century. As a result a lot of discoveries with the eyelens were performed. The significant impact on the improvement of vision correction medicine had the technique offered by Fedorov. The whole operation includes several small incisions and insections performed by doctor with special microscopic instruments. Of course such operations are truly difficult to go through and even some inconsiderable mistake can bring lots of awful consequences. The operation is really hazardous as it may cause some considerable results. In some cases that may be even the absolute loss of sight.

Eximer-laser vision correction

Fedorov's method was widely utilized but it wasn't ideal so some other methods appeared then. Doctors required to get some modern solutions and in 1980's the newest eximer laser was offered by scientists. Today physicians announce that techniques which utilize eximer lasers as base are really harmless and their efficiency is unbelievable. The preciseness of laser beam that performs some operations on the surface of the eyeball is provided by computer. The main cause of many troubles connected to vision is some curvature of tissues of the eyeball and eyelens. Operations that require the use of laser system are really difficult and there are some modern techniques which may propose the required accurateness.

PRK method

This technique is really widespread and it is based on use of eximer laser in medical objectives. The essence of this method is to eliminate the unevenness of the cornea by usage of evaporating of its tissues. That system is called non-contact as neither surgeon nor any tools contact with the face of an eye. However PRK method has got several drawbacks: some micro erosion appears during the operation and the operated person feels pain over a period of several days.

Lasik method

Current technique is the complex of microsurgical influence and eximer-laser system. Doctors from Largo lasik center performed experiments with it. The upper layers of the eyelens are detached and saved by means of some organic liquids. The most beneficial is that the upper layer wouldn't be injured and there will no pain during the period of the rehabilitation. That is not so difficult to correct some parts of inner structure of the eyelens. The last stage of the operation is to set the extracted parts of the eyelens on the proper position. The main benefit is that laser beam has considerably greater preciseness in case it is matched with any other surgical instruments. The most famous organization which carried out a huge amount of experiments is Greensboro lasik surgery.
