Customized ablations and wavefront analysis.

This is a new trend in refractive surgery. If you are myope of -3 Diopters, you will receive the same glasses, or lenses, or refractive laser procedure as any myope of -3 Diopters. And this works pretty well. However, you are not the same person as the other myope of -3 Diopters, and even your left eye is not the same as your right eye. Then comes the idea to "tailor fit" the treatment to one individual's eye. It means that the treatment is really personalized to the patient, but also to his eye's aberrations.

What is aberration ? If a ray of light is emitted and projected into the eye, it will be reflected and can be analysed by the computer. Its characteristics are unique and its changes or alterations will be called "aberrations".

Some people have more aberrations than others. It is therefore interesting to find out before the treatment who is going to have the highest benefit of the customized treatment, as many studies show now that only patients with high order aberrations will really benefit from the technique.

The goal is not only to improve vision, but mainly to improve the quality of the vision, for instance, in low light, contrast sensibility, night driving, etc.
Studies show that +/- 18% of the people have better vision in low light than before the surgery; a higher percentage describe less glares and haloes.
