What is Laser Eye Surgery?

Laser Eye Surgery is an incredibly effective method of improving vision and eliminating the need for glasses or contact lenses. Over 30 million people worldwide have had laser eye surgery.

The cornea is situated at the front of the eye and protects the iris, pupil and anterior chamber. This part of the eye enables us to focus and, in the case of those who need glasses or contact lenses, can be reshaped using a cool beam Excimer laser which gently reshapes the cornea in a matter of minutes, allowing your eyes to focus correctly, without the use of glasses.

The following videos explain how the eye works and describe some of the most common eyesight problems. After watching these, you’ll have a clearer idea of how laser eye surgery can improve your quality of life and put an end to wearing glasses and struggling with fiddly contact lenses for good.

Normal Vision

When light hits a normal eye, it’s focused at a single point on the retina at the rear. In turn, the cornea (the transparent part at the front) and lens inside the eye refract these rays of light, so they focus at the correct point and enable us to see clearly.

Below you will find the most common vision problems.

Short-Sightedness – Myopia

In short-sighted or myopic patients, incoming light is focused in front of the retina rather than directly on it. This is due to the eye being longer than normal, which results in distant objects appearing blurred.

Long-Sightedness – Hyperopia

In long-sighted or hyperopic patients, the reverse is true. Rather than being too long, the eye is usually shorter than normal, meaning light is focused behind the retina. As a result, the image on the retina is blurred when looking at objects nearby. read-more


The corneas of astigmatic patients are oval, rather than round in shape, meaning any rays of light hitting the eye focus at different points. This can cause problems when viewing objects near or far away, but can easily be corrected by the experts at Optilase.
