7. CONCLUSIONS THANK YOU FOR YOUR ATTENTION
Pseudo-accommodation of WIOL-CF appears to be caused by a combination of multiple factors, i.e. A-P movement, polyfocal optics, pupil size changes and optics deformation by the action of the ciliary muscle
The best results we found in the group of young and actively living patients
Patients complain sometimes for optical disturbances with little influence on overall satisfaction at all
WIOL-CF is potential IOL mainly for middle-age patient cataract surgery, actively living people cataract surgery, and for cataract patients with the risk of future vitreo-retinal surgery
