The purpose of this study was to record the visual outcomes of patients treated by six surgeons after implantation of a trifocal lens. The setting for this study comprised six ophthalmology units and eye clinics in Belgium and France, with a coordinating center in France, and data management and statistical analysis in France and Belgium. Ninety-four eyes from 47 patients were implanted with a trifocal FineVision(®) intraocular lens by six surgeons. Monocular and binocular, uncorrected and best distance-corrected, and photopic and mesopic visual acuity was measured, as well as the defocus curve between +4 D and -4 D with best distance correction. Near and far monocular visual acuities were similar to the data published after bifocal intraocular lens implantation. Intermediate vision was improved, and was demonstrated by scores of near visual acuity as well as far visual acuity with defocus -1.5 D-add lens. Far vision is maintained in mesopic conditions. The trifocal intraocular lens provides good far, intermediate, and near visual acuity.
