You might have known about such method of vision treatment as laser correction and its efficiency is considered to be the greatest. With help of some up to date systems physicians can cure such illnesses as nearsightedness, long sight and astigmatism. Probably the physicians Aurora lasik institute will propose some modern solutions to this system. People that utilize laser vision treatment can be assured that the consequences of the treatment will be constant and their sight will be normal.
The history of laser vision correction
The problem of vision correction became being reviewed in the beginning of the 20th century. Ophthalmologists started to discover some newest technologies to discover retina more appropriately. One of the most widespread methods is Fedorov's method. During the operation surgeon uses some unique microsurgical instruments and makes little incision and insections on the retina. Recently it has figured out that regardless of its efficiency this method of vision correction implies the appearing of several unexpected side effects. The operation is rather hazardous as it can cause some considerable consequences. In definite cases it may be even the complete loss of vision.
Eximer-laser vision correction
Fedorov's technique was widely used but it wasn't ideal so some other techniques appeared then. In the 1970's the first eximer laser was invented that had a huge influence on medicine in all its directions. Nowadays physicians announce that methods which use eximer lasers as basis are actually harmless and their efficiency is unbelievable. Laser beam is driven by some special computer system of reshaping of the cornea. The basic purpose of carrying out of any surgical operations is to get the proper form of the cornea. These days we may frequently hear about some other methods that are more efficient and safe. They are PRK photorefractive keratectomy and Lasik techniques.
PRK method
This technique is really frequently used and it is based on usage of eximer laser in medical purposes. Laser beam which is focused on the tissues of the retina evaporates some of them and the form of the eyelens become appropriate. Another advantage of current method is that neither instrument nor surgeon touch the face of the eye as the laser beam is utilized. However PRK method has 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 method. Physicians from Garden City lasik center tested it. During the operation definite upper layers of retina are detached and placed in some liquid to save it. The basic instrument which is utilized during the applying of lasik technique is a special microsurgical tool that cuts the upper part of the cornea. So other parts of eyeball are now obtainable for the laser beam. Another process which requires the highest degree of accurateness is to set the extracted sections to their locations. The computer program can't do any errors unlike the surgeon with surgical instruments. Every year lots of ophthalmologists from all round the globe assemble in Chapel Hill lasik surgery to define some problems and offer resolutions connected to laser vision correction.
