Wavefront-Lasik-surgeryWavefront Lasik surgery aims to achieve better vision than standard laser treatment or glasses and contact lenses. This gives the patient the benefit of having Super Vision, or vision beyond boundaries. It is customized to suit the individual’s eye.

Custom LASIK or Custom Wavefront LASIK, treatment replaces ‘the one treatment fits all’ with a procedure that is tailored to the individual eye. While standard laser eye treatment (without Wavefront guidance) gives very high quality results for the majority of patients, many peoples ‘eyes are not standard’. Their eyes might require a specially tailored treatment.

Nature has designed the eye like an Optical System, similar to something like a telescope. When you see some object, light rays from that object pass through different layers of the eye and then create an image of that object. When light passes through different layers the rays are subject to being distorted by the imperfections found in the cornea and the lens.

The distortions that are created are referred to as “aberrations.” The vast majority – 80% or more of these aberrations create common refractive errors, such as nearsightedness, farsightedness and astigmatism, which can be treated glasses and contact lenses, or by Standard Laser Correction. The remaining 20% of optical aberrations are known as “higher order aberrations”. These are not corrected by Conventional or Standard Lasik treatment. Higher-order aberrations, cause the visual glare and halos that cause night vision problems and affect quality of vision. It is seen in everyday life as glare experienced during night driving, surrounding car headlights, streetlights etc.

To achieve a customized corneal shaping, the higher order aberrations are measured using a Wavefront analysis system called an Aberrometer. The Aberrometer System lets the surgeon see refractive aberrations in clear and accurate, rotating 3-D images. These cannot be seen by regular or standard testing. This information is then transferred to the laser system, thus achieving Customized Treatment designed to suit your eye.

Advantage of Custom Lasik Surgery :

Wavefront or Custom Lasik gives a big advantage to those with large pupils and poor night time vision. The optical performance of the eye is measured at each and every place on the cornea, including the part which is used when the pupil is large. Laser treatment is then programmed to each tiny part of the corneal surface so that every area of the cornea gets the best correction. Contrast sensitivity in low lighting levels is increased and the risk of developing night time halos and glare is greatly decreased.
