VISUAL OUTCOMES OF IMPLANTATION OF MULTIFOCAL INTRAOCULAR LENS WITH ASYMMETRICAL LIGHT DISTRIBUTION

Abstract

Background: The results of implantation of refractive intraocular lenses (IOL), especially with an inferior segmental near add are of great interest due to advantages of the new lenses over more frequently used diffractive multifocal IOL. Aim: To assess the ocular optical performance of eyes implanted with a new IOL Lentis Mplus. Materials and methods: 78 patients (100 eyes) aged > 50 years were implanted with 100 IOLs Lentis Mplus. Preoperative examination included measuring uncorrected and corrected distance visual acuity, uncorrected and corrected near visual acuity. Postoperatively, uncorrected and corrected distance visual acuity, uncorrected and corrected near visual acuity (distance 33 cm) were estimated along with intermediate vision measurement using near-vision charts (60 cm). Results: On the day 3 after the procedure, distance visual acuity was good, and patients were able to near-reading of medium-size fonts. In 1 year, uncorrected visual acuity was 0.8–1.0 in two thirds of patients. 25% of patients needed distance visual correction from (-)0.5 to (-)0.75 D. Corrected visual acuity improved to 0.9–1.0. In 1 year, near visual acuity was 0.5 or more and intermediate visual acuity was 0.4 or more in all patients. In 78% of patients, 60 cm visual acuity was 0.5. Conclusion: Implantation of multifocal IOL Lentis Mplus produced good distance visual acuity and satisfactory (working) near and intermediate visual performance.
