Comparative Study of Clinical Outcomes Between 2 Types of Multifocal Aspheric Intraocular Lenses

Purpose: To evaluate the efficacy of the OptiVisTM Multifocal intraocular lens (IOL) and compare the clinical outcome between OptiVisTM and AcrySof<sup>&reg; ReSTOR<sup>&reg; D1. Methods: We reviewed 20 eyes of 11 patients implanted with OptiVisTM and 20 eyes of 10 patients implanted with AcrySof<sup>&reg; ReSTOR<sup>&reg; D1. The clinical outcomes of the 2 IOLs were evaluated 1 and 2 months postoperatively and consisted of distant, intermediate, and near visual acuity, depth of focus, contrast sensitivity, wavefront aberration, patient satisfaction, decentration and IOL tilt. Results: Intermediate vision was better in the OptiVisTM group. There were no statistical differences between the 2 groups with respect to distant vision, near vision and wavefront aberration, contrast sensitivity, decentration and IOL tilt. Depth of focus was deeper in the OptiVisTM group at the intermediate visual acuity zone. There were no statistically significant result differences between postoperative 1 and 2 months. Conclusions: The OptiVisTM multifocal IOL provided satisfactory visual acuity at distance, near, and intermediate with no apparent reduction in contrast sensitivity. The IOL can be effective for improving patient satisfaction after cataract surgery as well as correcting presbyopia.
