What does LASIK rectify?

• Myopia (Short sight)

• Hyperopia (Long sight)

• Astigmatism

• Presbyopia (Chalees)

• Higher order aberrations (HOA)

The human eye performs better than a modern digital camera! The cornea and crystalline lens focus the image on the retina. This high resolution image is transmitted to the brain through the optic nerve by a stream of micro electrical pulses. Good eyesight depends on the integrity of all these structures and their functions. Some eyes can’t focus the image on the retina due to variation in length of the eye or shape of the cornea.

Myopia ( Short sightedness)

In Myopia or short sight, the image gets focused at a point before the rays reach the retina. The eye is too long or its focusing power is too strong. Distance objects appear blurred.

Hyperopia (Long sightedness)

In Hypermetropia or far sight the image is not yet focused when the rays reach the retina. The eye is short or its focusing power is weak. Objects both at distance and near may be blurred in this condition.

Astigmatism

In Astigmatism the irregularly shaped cornea makes the image never in full focus. Parts of the image are focused at different levels.

Presbyopia

Presbyopia occurs after 40 years due to aging process. Near objects are blurry. It occurs early in Hyperopes and later in Myopes.
