IOLA Plus 4C
IOLA 4C – A Model Eye configuration. The measurement process consists of two stages. The first one is the power mapping stage identical to that of the standard IOLA Plus. The second one is the MTF measurement stage where a Model Eye-compliant lens simulating a human cornea is automatically inserted into the optical path.
The IOLA 4C includes a cassette which can carry up to four cornea-simulating lenses, thus allowing measurement of MTF in different Model Eyes.
