The WASCA Aberrometer and the CRS Master Analysis system

This laser is the only laser linked to a wavefront sensor (Aberrometer) with sufficient resolution to accurately measure eyes that have large amounts of irregular wavefront error. Put in numbers, the WASCA aberrometer has 800 spots resolution, while the next two closest units available (VISX and Alcon -Autonomous) have around 200 spots to measure the wavefront. Your wavefront map will be measured by the WORLDS HIGHEST RESOLUTION aberrometer, the Carl Zeiss CRS Master™. From this map, a detailed treatment plan can be created, taking into account your unique optical distortions, glasses prescription, pupil size, and visual needs. The CRS Master offers a new level of diagnosis and treatment, further refining your laser vision correction. Each Carl Zeiss CRS Master assessment involves an extra diagnostic (screening) process extensive enough to let the surgeon see every individual eye’s unique optical characteristics. With a CRS Master assessment, you can rest assured that your surgeon now has an even broader base of information on which to decide whether your eyes are suitable for treatment, and to plan the right treatment for you.

The CRS Master Aberrometer measures the eye from the centre to the outer edges (the periphery) of the pupil. This is especially important, because at night your pupils open up and more light is scattered in the periphery of the pupils. Your surgeon needs to know as much about your night-time as your day-time vision. In a recent study, four times as many patients were very satisfied with their night vision after Custom LASIK, compared to their night vision with their glasses or contact lenses before the procedure!
