Visual outcomes after implantation of a refractive multifocal intraocular lens with a +3.00 D addition.

摘要

PURPOSE: To assess the visual outcomes after cataract surgery with implantation of a refractive multifocal intraocular lens (IOL) with a +3.00 D addition (add). SETTING: Centro Internacional de Microcirugia Ocular, Seville, Spain. METHODS: This prospective study evaluated visual outcomes after cataract surgery with implantation of a Rayner M-flex 630F +3 IOL over a 12-month follow-up. Monocular and binocular uncorrected and corrected distance, intermediate, and near visual acuities were recorded. Distance contrast sensitivity under photopic and mesopic conditions, subjective dysphotopic phenomena, and subjective spectacle dependence were assessed. RESULTS: The study enrolled 32 eyes of 22 patients. Twelve months postoperatively, the mean monocular corrected distance acuity was 0.03 +/- 0.05 logMAR and the mean corrected near acuity was 0.04 +/- 0.05 logMAR. The binocular uncorrected and corrected near acuity was 0.25 +/- 0.08 logMAR and 0.03 +/- 0.02 logMAR, respectively, at 6 months, with no changes thereafter. No patients reported dysphotopic phenomena at the 12-month visit. Of patients having binocular IOL implantation, 90% were spectacle independent for distance vision and 70% for near vision at 6 months. CONCLUSION: The refractive multifocal IOL with a +3.00 D add provided satisfactory visual outcomes through a full range of vision.
