What are the types of refractive errors?

– Myopia or short sightedness
Refers to a state of the eye, wherein the rays of light coming from a distant target, get focused at a point in front of the retina. In this situation, minus powered glasses or contact lenses are necessary to focus this image onto the retina.

– Hyperopia or longsightedness
Refers to a state of the eye, wherein the rays of light coming from a distant target, get focused at a point behind the retina. In this situation, plus powered glasses or contact lenses are necessary to focus this image onto the retina.

– Astigmatism or cylindrical power
Refers to a state of the eye, wherein the rays of light coming from a distant target, cannot focus at a single point on the retina. In this situation special lenses of different curvature are required to focus the light onto the retina.

– Presbyopia
This is related to the aging process of the eye and results in blurred near vision. Currently, laser refractive treatment cannot be used to correct this error.

How the eye functions?

The eye functions by focusing light passing through the cornea and lens on to the retina (inner back of the eye). The cornea accounts for approximately two-thirds of the total focusing power of the eye.
The shape of the cornea and the eye are not always perfect, causing a distortion to the focusing of the light rays on the retina. The imperfections are known as refractive errors.

What is the Laser Refractive Eye Surgery?

It is painless, outpatient procedure carried out privately funded basis ( is it generally not covered by health insurance, although it is always wise to consult with your health insurance company).
The laser is used to alter the shape of the cornea, which changes the way the eye focuses light
