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

Abstract

This study assessed 5-year results of rotationally asymmetric multifocal intraocular lens (IOL) with +1.5diopters (D) near addition (Lentis Comfort LS-313 MF15, Teleon Surgical B.V., Spankeren, Netherlands). In 38 eyes of 20 patients (76.8 ± 4.6years) who were examined at both 1 and 5years after surgery, clinical data were retrospectively collected. Corrected and uncorrected distance visual acuity (5m) and uncorrected and distance-corrected intermediate visual acuity (70cm) were excellent, with no significant differences between 1 and 5years after surgery. Uncorrected and distance-corrected near visual acuity (30cm) remained lower. Contrast sensitivity was within the normal range at both 1 and 5years. 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 5years 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. During 5years after surgery, low-add-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. University Hospital Medical Information Network Clinical Trials Registry (UMIN-CTR) identifier UMIN000048353.
