12.2.1 Customized Ablations
In Zernike Factors, the profile definition considers the differences between the different devices
that we are linking to the CAM software, therefore to AMARIS:
a) CSO (Eye-Top)
b) Scout (Corneal Wavefront Analyzer)
c) WFS (Ocular Wavefront Analyzer) or irx3 Imagine Eyes (Ocular Wavefront Analyzer)
d) CSO SIRIUS Scheimpflug Camera
e) CSO Peramis
12.2.2 Surface and Stromal Treatments
Based on good experience with the profile definition as used in the previous ESIRIS Excimer laser
with CAM software, we have observed that LASIK patients (stromal treatments) needed more
adjustment (more number of pulses, considered as deeper ablations) than PRK/TransPRKor
LASEK patients (surface treatments). Moreover, we have observed a higher tendency for
overcorrections after thin-flap LASIK (anterior stromal treatments) as compared to thick-flap
LASIK (deep stromal treatments).
The observed behaviour is to be balanced by the number of pulses and not with deeper ablations
with the AMARIS Excimer laser. For that reason, we have included a Shot Depth Factor parameter
depending on the applied technique.
