Laser Can Help Patients to Get Rid of Eyelens Problems
Nowadays laser correction is believed to be one of the most progressive trends in the area of up to date ophthalmology. With lots of newest technologies such significant eye disease as astigmatism, nearsightedness and long sight may be cured. Doctor John Zorn said that Palm Springs lasik institute has an opportunity to develop such techniques a lot. Persons that utilize laser vision treatment can be sure that the consequences of the treatment will be constant and their vision would be nice.
The history of laser vision correction
The history of laser correction systems began in the early 1960's in several states simultaneously. Such late developing of that area of medicine is dependent on the lack of needed technologies. The great influence on the improvement of sight treatment medicine had the method proposed by Fedorov. During the operation doctor utilizes some special microsurgical tools and makes small incision and insections on the cornea. Lately it has turned out that regardless of its effectiveness this technique of sight correction implies the appearing of some unexpected side effects. The retina goes through the mechanical actions and the operated person may have some worsening of the vision or in some cases it can be the complete loss of sight.
Eximer-laser vision correction
Doctors began improving different modern methods utilizing principles of Fedorov's technique. In the 1980's there was a great invention which affected this area considerably - eximer laser. It is hard to believe but the newest eximer laser methods can provide the safest and the most efficient operations. The preciseness of laser beam which performs some actions on the surface of the eyeball is provided by computer. The main object of performing of any surgical operations is to get the normal form of the retina. Operations that require the use of laser system are truly complicated and there are some modern methods that may propose the needed accurateness.
PRK method
This technique is the first instance of use of eximer laser in medical purposes. The essence of current method is to delete the unevenness of the cornea by means of evaporating of its tissues. Physicians relate this method to the non-contact techniques as all the actions are performed only by means of laser beam. Nevertheless PRK method has got some disadvantages: some micro erosion can take place during the operation and the operated person feels pain over a period of several days.
Lasik method
This method is the complex of microsurgical influence and eximer-laser technology. The primary experiments were performed by the scientists of Newnan lasik center. During the operation definite upper pats of retina are detached and placed in special liquid to save it. The most beneficial is that the upper tissues wouldn't be injured and there will no pain during the period of the rehabilitation. So other sections of eyelens are now reachable for the laser beam. The other action which demands the highest degree of accurateness is to set the extracted parts to their places. The basic benefit is that laser beam has got considerably higher preciseness if matched with any other surgical instruments. There are lots of centers that try to improve better techniques of sight treatment and probably the most famous of them is Stillwater lasik surgery.
