Please, use your IOL Master for calculating WIOL-CF® after you enter the latest calculation constants published for WIOL-CF® by ULIB (http://ocusoft.de/ulib/). Preferred formula is Haigis.
Here is our general recommendation how to approach calculation of WIOL-CF power:
Refractive patient (Clear Lens Exchange – good visual acuity to all distances required)
Cataract patient (visual acuity to far is priority, extended range to intermediate distance)
