There are a lot of methods of vision correction nowadays but not all of them are truly helpful and effective. The most efficient method is laser operations. With lots of newest systems such significant eye disease as astigmatism, nearsightedness and long sight can be treated. Maybe the physicians Sherman Oaks lasik institute will offer some new solutions to current method. Persons that utilize laser vision correction may be sure that the results of the treatment will be constant and their vision will be nice.
The history of laser vision correction
The first phase of the improvement of laser treatment systems began in the middle of the 20th century. Ophthalmologists began to discover some modern systems to discover retina more appropriately. One of the most widespread systems is Fedorov's method. The entire operation includes several little incisions and insections performed by doctor with some microscopic instruments. After the first test operations were carried out the doctors ascertained that these operations can do harm to the eyelens and several other sections of eye. Doctors recommend resort to such operations in case the situation with vision is not despairing as the operation is actually complex and dangerous.
Eximer-laser vision correction
Surely the developing of some modern methods of sight correction was going on. Physicians wanted to get lots of new solutions and in 1980's modern eximer laser was offered by scientists. Nowadays doctors say that methods that utilize eximer lasers as base are actually safe and their efficiency is fabulous. The accurateness of laser beam which performs some actions on the surface of the eyeball is provided by computer. The basic purpose of carrying out of any surgical operations is to set the proper shape of the cornea. There are two the most renowned techniques that are commonly used today: PRK photorefractive keratectomy and Lasik.
PRK method
The uniqueness of current technique is that it is the first application of eximer laser in medic purposes. Laser beam that is focused on the tissues of the cornea evaporates some of them and the shape of the eyelens become proper. Another advantage of current method is that neither tools nor surgeon contact with the face of the eye as the laser beam is utilized. However PRK system has got some disadvantages: some micro erosion can take place during the operation and the patient feels pain over a period of a week.
Lasik method
This method is the combination of microsurgical influence and eximer-laser technology. The initial experiments were carried out by the scientists of Pocatello lasik center. The upper substances of the eyelens are detached and saved by means of special organic liquids. The most beneficial is that the upper tissues wouldn't be damaged and there will no pain during the process of the rehabilitation. The eyeball becomes open and all its parts are reachable. Another process that demands the highest degree of accurateness is to set the detached sections to their locations. The computer program can't do any mistakes unlike the surgeon with surgical instruments. The most renowned institution which carried out a great deal of experiments is Suffolk lasik surgery.
