Subjective Outcomes After Bilateral Implantation of an Apodized Diffractive +3.0 D Multifocal Toric IOL in a Prospective Clinical Study

Abstract

PURPOSE: To assess subjective outcomes after bilateral implantation of an aspheric apodized diffractive +3.0 diopter (D) multifocal toric intraocular lens (IOL). METHODS: This was a prospective, single-arm, 6-month study conducted at five study sites in Europe and South America. Forty-nine patients requiring bilateral cataract extraction or refractive lens exchange and IOL implantation in both eyes with preoperative regular corneal astigmatism of 0.75 D or greater and 2.5 D or less received bilateral AcrySof ReSTOR +3.0 D toric IOLs (Models SND1T3, SND1T4, or SND1T5; Alcon Laboratories, Inc., Fort Worth, TX). Subjective questionnaires were administered preoperatively and 6 months postoperatively. RESULTS: Patient subjective experience with visual tasks at all distances improved from the preoperative visit to the 6-month visit. At the 6-month visit, 90% (36 of 40) of respondents reported complete freedom from corrective wear compared with 14% (6 of 43) pre-operatively. On a scale of 0 (worst) to 10 (best), the mean score that patients rated their uncorrected vision was 7.9 ± 1.9 at 6 months (n = 37) compared with 3.6 ± 2.0 at the preoperative visit (n = 38). CONCLUSIONS: Six months following bilateral implantation of the AcrySof ReSTOR +3.0 D toric IOL revealed improved subjective experience, increased spectacle freedom, and higher satisfaction when compared with the preoperative baseline.
