Laser Will Assist Patients to Get Rid of Eyelens Illnesses
Today laser treatment is considered to be one of the most progressive tendencies in the area of up to date ophthalmology. With some modern technologies such significant eye disease as astigmatism, nearsightedness and long vision may be treated. Such techniques are being improved in San Rafael lasik institute. The most considerable benefit is that the vision treatment is constant and the vision won't become worse in future.
The history of laser vision correction
The history of laser treatment methods began in the the beginning of the 1960's in different states simultaneously. As a result lots of experiments with the eyelens were carried out. The great impact on the improvement of vision correction medicine had the technique offered by Fedorov. During the operation surgeon utilizes some special microsurgical instruments and performs small incision and insections on the cornea. Lately that has turned out that despite of its efficiency current method of vision treatment implies the appearing of several unexpected side effects. The retina goes through definite mechanical actions and the patient may have some worsening of the vision or in some cases that may be the complete loss of sight.
Eximer-laser vision correction
Scientists began developing different modern techniques utilizing principles of Fedorov's method. Physicians required to have some modern solutions and in 1970's the newest eximer laser was proposed by scientists. The modern sight treatment methods are based exactly on eximer laser technologies and they are considered to be the most effective. The preciseness of laser beam that performs some operations on the surface of the eyeball is provided by computer. The main purpose of carrying out of any surgical operations is to get the proper shape of the cornea. Operations that demand the usage of laser system are really difficult and there are some modern techniques that can offer the required preciseness.
PRK method
This method is the first instance of usage of eximer laser in medical objectives. The essence of current system is to delete the unevenness of the cornea by means of evaporating of its substances. Another advantage of this method is that neither tools nor surgeon contact with the surface of the eye as the laser beam is used. Such operation is considered to be really painful for the persons as the cornea is being seriously damaged.
Lasik method
This method is the newest one as there is a combination of mechanical and laser instruments. The initial tests were carried out by the scientists of Lincoln lasik center. During the operation some upper pats of cornea are detached and placed in some liquid to save it. The basic instrument that is utilized during the applying of lasik technique is a special microsurgical instrument that cuts the upper level of the cornea. The eyelens becomes open and all its parts are reachable. After the operation is over the detached parts should be attached to the eyeball. The computer program can't make any errors unlike the surgeon with surgical tools. There are lots of establishments that try to improve better methods of vision treatment and maybe the most famous of them is Greenwood lasik surgery.
