The femtosecond laser cuts a thinner flap (thus saving tissue) that is more reliable (fewer complications), more reproducible, and optically neutral (no interference with the treatment for myopia). It replaces the microkeratome, a sort of small carpenter’s plane, which can lead to per-operatory problems, such as blockage or poor control of flap thickness.

The Zyoptix software combines the data supplied by two different types of diagnostic equipment: the topograph (which analyses the cornea’s shape and thickness) and the abberometer (which searches for aberrations in the eye). The system gathers data on your cornea’s structure (topography) and the measurements of your optic system taken using advanced wave front technology (abberometry). These data are recorded on a ZYOPTIX card, which, when introduced into the Technolas 217z laser, guides the patient’s personalised treatment.

Like fingerprints, each person’s two irises are unique and can be used to identify that person. Iris-recognition has numerous advantages:
- The treatment can only proceed if the system recognises your iris. You can therefore be absolutely certain that you will get the right treatment for the eye in question.
- Patient identification is rapid and automatic during treatment and follow-up visits.
- The procedure is more convenient, because the system calls up your treatment file as soon as it recognises your iris.
- We are always sure that we have the right treatment file for the right patient and the right eye.
