Five-Year Clinical Outcomes of Low-Add-Power Segmented Rotationally Asymmetrical Intraocular Lens

Abstract

Introduction: This study assessed 5-year results of rotationally asymmetric multifocal intraocular lens (IOL) with ?1.5 diopters (D) near addition (Lentis Comfort LS-313 MF15, Teleon Surgical B.V., Spankeren, Netherlands). Methods: In 38 eyes of 20 patients (76.8 ± 4.6 years) who were examined at both 1 and 5 years after surgery, clinical data were retrospectively collected. Results: Corrected and uncorrected distance visual acuity (5 m) and uncorrected and distance-corrected intermediate visual acuity (70 cm) were excellent, with no significant differences between 1 and 5 years after surgery. Uncorrected and distance-corrected near visual acuity (30 cm) remained lower. Contrast sensitivity was within the normal range at both 1 and 5 years. The percentage of patients who reported ''never or hardly use spectacles'' for far, intermediate, and near vision was 95.0%, 85.0%, and 35.0%, respectively. Glare and halo were slightly increased from 1 to 5 years after surgery, but the severity remained none or mild. All patients reported ''very high'' or ''high'' level of overall satisfaction. There were no notable postoperative complications. Conclusions: During 5 years after surgery, lowadd-power segmented multifocal IOL maintained excellent distance and intermediate visual acuity as well as good contrast sensitivity. Glare and halo symptoms were mild, and patients' satisfaction level was high.

Clinical Performance of New Enhanced Monofocal Intraocular Lenses: Comparison of Hydrophobic C-loop and Hydrophilic Plate-Haptic Platform

“…The main goal of this evaluation was to provide initial clinical data and verify if the lens is safe and shows good postoperative results. Lens models with different optics but the same material and haptic design have been implanted in clinical routine many times and have been observed over a long period of time and proved their safety in clinical routine and in studies [ 19 – 21 ]. The aim of the present manuscript is to provide first clinical data for a new variant of a monofocal lens and discuss the optic design and laboratory results of the optical bench analysis.…”
