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 OphthalmologyCharles University and Central Military Hospital, Prague, Czech Republic*Biovision s.r.o., Prague, Czech RepublicESCRS 2008 Berlin
2 WIOL-C/CF “Full Optics” hydrogel IOL (1992 – 2008) WIOL MAIN FEATURES:Large optical zone > 8.6 mmA constant = 120High water content > 41 %Excellent biocompatibilityNegatively charged surfaceImplantable through 2.6 mm incisionPlasticized for implantation (CF model)Elastic properties with delayed recovery (“lazy rubber”)Grows and softens in the implanted stateSHARP EDGEMENISCOID ANTERIOR SURFACECONICAL FASETTEHYPERBOLOID SURFACE CONTACTING POSTERIOR CAPSULEOPTICAL TRANSITION ZONEMETHODSSurgery from IX/2005 to VI/200751 eyes (30 patients)Age ranging from 50 to 71 yearsNo macular pathologySurgery performed through 2,65 mm corneal tunnelFolded WIOL-CF implanted in plasticized state by Medicel injector (cartridge 2,2mm)AC constant 120

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 muscleThe best results we found in the group of young and actively living patientsPatients complain sometimes for optical disturbances with little influence on overall satisfaction at allWIOL-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 surgeryTHANK YOU FOR YOUR ATTENTION7
