There are lots of methods of vision treatment today but not all of them are really helpful and effective. The most effective system is laser operations. With help of some up to date systems physicians are able to treat such illnesses as nearsightedness, long sight and astigmatism. Such methods are being improved in Santa Clara lasik institute. The consequences of such curing courses are commonly constant and do not change during the whole life.

The history of laser vision correction

The history of laser treatment methods started in the the beginning of the 1960's in several states simultaneously. Ophthalmologists began to develop some modern systems to study eyeball more appropriately. The famous Soviet doctor Fedorov invented some methods then. The whole operation includes several little incisions and insections carried out by doctor with special microscopic tools. After the initial test operations were performed the doctors ascertained that these operations may do harm to the eyelens and some other parts of eye. Doctors recommend not to use these operations if the situation with vision is not hopeless as the operation is actually complicated and risky.

Eximer-laser vision correction

Of course the improvement of some new methods of sight treatment was continuing. In the 1980's there was a great invention which influenced this area considerably - eximer laser. Nowadays physicians say that techniques which utilize eximer lasers as base are actually safe and their efficiency is unbelievable. Laser beam is driven by some special computer system of reshaping of the retina. As the shape of the eyelens is modified, some normal features can be regained so beams are being aimed on the retina appropriately. Operations that demand the usage of laser system are really complicated and there are some newest techniques that can offer the needed preciseness.

PRK method

This technique is actually frequently used and it is founded on use of eximer laser in medical objectives. To set right the shape of retina the laser beam that has high temperature evaporates some superfluous parts of eyelens. Physicians relate this method to the non-contact methods as all the actions are carried out only by usage of laser beam. However PRK method 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

Current method is the complex of microsurgical influence and eximer-laser technology. Doctors from Springfield lasik center performed experiments with it. During the operation definite upper pats of retina are removed and placed in some liquid to save it. The most beneficial is that the upper layer wouldn't be damaged and there will no pain during the process of the rehabilitation. So other parts of eyeball are now reachable for the laser beam. After the operation is over the detached tissues ought to be attached to the eyelens. The main benefit is that laser beam has considerably higher accurateness if matched with any other surgical tools. There are lots of centers that try to improve nicer techniques of vision correction and maybe the most famous of them is Rock Hill lasik surgery.
