Laser eye surgery is a revolutionary technology that can partially, or totally, eliminate your dependency on glasses and contact lenses. The procedure is done on an out-patient basis (so you can go home the same day) and people normally return to work within a week. Laser eye surgery produces permanent results and enables millions of people to throw away their specs every year, bringing aesthetic and practical benefits to everyday living.

How the eye works
At the very front of your eye there is a thin, transparent surface called the cornea, a curved structure that provides most of the eye’s focusing power. This is helped by the lens, which sits behind the iris (the coloured part) bringing light rays into even sharper focus before they land on the retina at the back of the eye. The retina captures images upside-down, and sends them to the brain for processing.
If the cornea or lens start to change shape, perhaps due to the natural aging process, it can cause unfocused or blurry vision. This elongation of the eye is thought to be hereditary, causing people to develop myopia (short-sightedness) or hyperopia (long-sightedness) over time.
Both of these conditions require corrective lenses, either for specific tasks (like reading, driving, or watching TV), or throughout the day for general use, to enable people to live their lives in full focus. To begin with, many people opt for spectacles or contact lenses, or a combination of both. However, eye laser surgery is a hi-tech alternative that could free you from this burden forever.
