Why wavefront analysis?
The corneal wavefront is emerging as a new tool for defining the optical status of the cornea as well as the entire eye. Analysis of the corneal wavefront can help clinicians understand symptoms, make diagnoses, and design surgeries.

While a traditional LASIK is based on correction values that were determined with eyeglasses or contact lenses, wavefront analysis allows for an optimized treatment. It measures the refractive power of the eye at more than 25.000 different spots and produces a "map of the eye", which contains the precise refractive power for every measured spot and is often called "fingerprint of your vision". This map is later used to perform the vision correction by taking tiny differences in the refractive power of the cornea into account, therefore optimizing the result.

The WaveLight® Oculyzer™

diagnostic device is based on the proven Pentacam HR technology, providing non-contact measurement and analysis of the complete anterior eye segment. Measurements are performed from the anterior surface of the cornea to the back of the lens.
