Impaired sight and eye infections are common because the eye is very fragile. This small structure is what retrieves information about the world that we see. Our eyes use a complicated method to form the images we see, using primarily the cornea, iris, and retina. Thanks to lasik eye surgery, we are able to correct problems to these areas, which can cause eye care issues if not treated.

Impaired vision is the result of a problem with the retina and the cornea, since the brain receives and interprets electrical impulses generated by images falling onto the retina. Long sightedness is a visual impairment resulting from too short a distance in the eye between the cornea and the retina. Focusing the eye on close objects becomes difficult. Conversely, short sightedness is caused by too long a focal length in the eye or excessive curvature. As a result, the eye will find it hard to see objects at a distance.

Astigmatism is another vision disorder that results if the eyeball is not a perfect sphere. We cannot see clearly if the eye is not in the right shape to allow proper focusing of the image attributes on the retina. All these refractive errors can be corrected using lenses. The power of these lenses is prescribed by our ophthalmologist after testing our eyes.

Most of us do not like to wear prescription eye glasses as they affect our social life. Some others find the eye glasses a hindrance to their activities (e.g. sportspersons). For these persons, a popular option by which they can avoid wearing prescription glasses is Laser in-situ keratomileusis also know as lasik eye surgery. In this surgical procedure, a flap of cornea is lifted, allowing exposed tissue to be removed by laser; and the flap is then put back.

If you are thinking about lasik eye surgery you might want to consider this; it has a short recuperation period and is less painful. Studies have shown that you are model candidate if you have a thick enough cornea and it is said to work best on patients with short sightedness and mild long sightedness.

For individuals who do not wish to wear corrective lenses, lasik eye surgery is a viable alternative. It is recommended however that individuals who have had lasik eye surgery have regular eye exams to prevent complications from arising. It is also important to remember that the eyes should not be rubbed vigorously following the procedure.
