Implantation of Multifocal Add-On IOLs Simultaneously with Cataract Surgery: Results of a Prospective Study

Background: A prospective study was carried out to evaluate postoperative visual acuity and patients satisfaction after implantation of a multifocal add-on IOL. Patients and Methods: In 50 eyes of 25 patients operated by two surgeons "group A (MK) = 15 patients; group B (MWR) = 10 patients" with age-related cataract after "normal" cataract surgery, sulcus-fixated multifocal add-on IOLs (MS 714 PB Diff., Dr. Schmidt Intraocularlinsen, Sankt Augustin) were implanted. 12 weeks after surgery in both groups the following parameters were evaluated: far visual acuity; intermediate visual acuity (1 meter) and near visual acuity (33 centimeter). In addition, the patients satisfaction was measured in three steps (1 = excellent; 2 = satisfied; 3 = not satisfied) ermittelt. In group A also contrast sensitivity was measured using the Ginsberg box. Results: Surgery was performed in all cases without complications. No postoperative complications were observed. After 12 weeks the results in both groups were comparable. Median distance visual acuity was 0.05 +/- 0.02 (LogMar) uncorrected and 0 +/- 0.05 (LogMar) with correction. Intermediate visual acuity was 0.25 +/- 0.06 (LogMar) uncorrected (0.1 +/- 0.09 (LogMar) with correction. Near visual acuity was 0.2 +/- 0.07 (LogMar) and 0.15 +/- 0.02 (LogMar), respectively. Patients satisfaction was 80-90%. Conclusions: Sulcus-fixated add-on IOLs are a useful addition to our refractive surgical armamentarium. The present results encourage us to use this method as a standard procedure.
