Secondary multifocal intraocular lens implantation: A novel management strategy for white cataracts

Abstract

Objectives: This study was designed to analyse the outcomes of secondary multifocal intraocular lens implantation in eyes with white cataracts. Methods: White cataract patients undergoing secondary multifocal intraocular lens implantation between June 2014 and January 2015 were evaluated prospectively. As opposed to a conventional primary intraocular lens implantation for an optimal patient, the white cataract was first extracted, followed by optical biometry measurements. Whether or not the patient had adequate visual acuity was identified, and the multifocal intraocular lens was implanted secondarily. A total of five appropriate white cataract patients were enrolled in this secondary multifocal intraocular lens implantation study and were retrospectively reviewed. Results: All five secondary implantations of the multifocal intraocular lenses were successful, without obvious adverse events. The uncorrected near visual acuity LogMAR was 0.4–0.5, and the distance visual acuity was −0.1 to 0.1 after 12 months of the multifocal intraocular lens implantation. All patients achieved satisfactory near and distance visual acuities and spectacle freedom. Conclusion: Two-stage multifocal intraocular lens implantation is a safe and novel technique for the management of white cataract patients to optimise near and distance visual acuities.
