To assess long term results of diffractive multifocal intraocular lens implantation (Restor , Alcon) in patient’ s visual function.
: Ophthalmos Research and Therapeutic Institute, Athens, Greece
Retrospective study including 98 eyes (51 patients ) operated for cataract that completed a minimum of 5 years follow up. Distance and near visual acuity was assessed along with patient’s satisfaction, dependence on glasses and presence of photopic phenomena.
Mean follow up period was 73 months. At the end of the follow up 76,5% of eyes had CDVA better or equal to 20/25, and 83,6% CNVA better or equal to J2 (at 35 cm). 4 eyes needed further LASIK refractive surgery for correction of postoperative residual astigmatism. 8 patients needed glasses for all tasks while 10 patients only used distance glasses occasionally. Patient’s satisfaction overall was high. Adaptation to photopic phenomena improved with time.
Visual function of eyes implanted with a diffractive intraocular lens remains satisfactory 6 years following implantation. FINANCIAL INTEREST: NONE
