  1. Long term results with (pseudo) accommodative WIOL-CF Pasta, J., Hubackova, J., Stoy, V.A .*,Drunecky, T.* WIOL-CF seven years after implantation (Co-author‘s left eye in 2006) Department of Ophthalmology Charles University and Central Military Hospital, Prague, Czech Republic *Biovision s.r.o., Prague, Czech Republic ESCRS2008Berlin

  2. MENISCOID ANTERIOR SURFACE OPTICAL TRANSITION ZONE CONICAL FASETTE SHARP EDGE HYPERBOLOID SURFACE CONTACTING POSTERIOR CAPSULE WIOL-C/CF “Full Optics” hydrogel IOL (1992 – 2008) • WIOLMAIN FEATURES: • Large optical zone > 8.6 mm • A constant = 120 • High water content > 41 % • Excellent biocompatibility • Negatively charged surface • Implantable through 2.6 mm incision • Plasticized for implantation (CF model) • Elastic properties with delayed recovery (“lazy rubber”) • Grows and softens in the implanted state • METHODS • Surgery from IX/2005 to VI/2007 • 51 eyes (30 patients) • Age ranging from 50 to 71 years • No macular pathology • Surgery performed through 2,65mm corneal tunnel • Folded WIOL-CF implanted in plasticized state by Medicel injector (cartridge 2,2mm) • AC constant 120

  3. Far Vision Near Vision [%] [%] UCVA

  4. Far Vision Near Vision [%] [%] J No. Comparison of monocular vs. binocular UCVA

  5. Average contrast sensitivity levels of WIOL-CF patients • Worse than monofocal artefakia • On upper level of average population limit • Better than cataractous eye • Typical for aspherical lenses

  6. SPECTACLES FOR READING SPECTACLES FOR COMPUTER OVERALL PATIENT SATISFACTION RATE SCHEIMPFLUG’S IMAGE OF WIOL-CF

  7. CONCLUSIONS • 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 • THANK YOU FOR YOUR ATTENTION
