following functions:
•
Cornea image acquisition and topographic analysis
•
Eye Axial Biometry
•
Dynamic pupillometry acquisition: recording of a sequence of pupil images as the light conditions
change. Static pupillometry acquisition in controlled light conditions (photopic, mesopic and
scotopic)
•
Fluorescein analysis: picture and/or video acquisition that allows checking contact lens positioning,
or assessing cornea’s artefacts and the lachrymal
film (rupture time)
•
Analysis of wave front corneal aberrations generated by the front surface of the cornea with Zernike
analysis: information on the optical properties of the cornea and the optical problems that may
affect sight
•
Contact lens simulation: the software selects from a database the lens best suited to the eye and
allows different lenses to be compared
