Is bad vision becoming a problem for you? Vision problem has affected a major part of the world population. As such, glasses and contact lenses act as top rated health aid to you. But would that help you in correcting your vision? No, it would not!

With the use of glasses and lenses, the components of your eye are not stimulated but rather suffer from a narrow range of use. It is a word of mouth that suggests eye exercises to naturally correct eye vision. Natural correction involves eye exercises and relaxation techniques to enhance the optimal muscle strength and coordination of the eyes.

Although exercise is the best alternative one can go for, but our fast changing lifestyles and busy schedules provide hardly any time for ourselves. What to do if we don't get time to de-stress ourselves? Eye vision correction through surgery would be the next possible option in that case.

Remarkable advances have been made in the field of refractive eye surgery for vision correction from time to time. There are number of options available to help the people reduce their dependencies on contact lenses or eyeglasses. The surgery is beneficial to people with problems of myopia (near sightedness), hyperopia (far sightedness) and astigmatism.

Myopia is defined as a visual defect in which distant objects appear blurred as images are focused in front of the retina rather than on it. Hyperopia is another abnormal condition of the eye in which vision is better for distant objects as images are focused behind the retina. Astigmatism is an abnormal condition in which the eye has various focal points causing images to be blurred and distorted. The unequal curvature of one or more refractive surfaces of the eye, usually the cornea, prevents light rays from focusing clearly at one point on the retina.

Today, vision corrective surgery provides various options, a few among them include:

?Radial keratotomy (RK)

?Laser vision correction

Photorefractive keratotomy

Laser in situ keratomileusis (LASIK)

Laser thermal keratoplasty

?Intacs

?PRELEX (presbyopic refractive lens exchange) or clear lens extraction.

Although these surgeries are well advanced with technology, but being a surgery, it does involves some risk factors. In laser vision corrections, risk may occur during the procedure of surgery or at the time of healing. Sometimes infection of the cornea or inflammation can also occur. Refractive complications include under-corrections or over-corrections which may demand for further retreatment. The most common complication after the treatment is of dry eyes. Dry eyes following Lasik may be due to decrease in corneal sensation as the microkeratome cuts through the superficial corneal nerves.
