Abstract

Purpose: To evaluate the visual performance of patients implanted with a new bi-aspheric, +3-D nonblended segment, multifocal IOL.

Methods: Forty eyes of 20 patients undergoing cataract or clear lens surgery were bilaterally implanted with the lens, and visual acuity (VA), contrast sensitivity, defocus curves and halometry were assessed 3 months postsurgery.

Results: Residual refractive error was 0.01 ± 0.47 D (89% within ± 0.5 D). Uncorrected distance VA was 0.11 ± 0.17 logMAR; 78% of eyes could read ≤ J3. Contrast sensitivity was good (1.67 ± 0.07 log-units), and defocus showed a 1.5-2.5 D near-addition. Halometry showed < 1 degree of debilitating light scatter.

Conclusions: This new aspheric, segmented IOL provides a good visual outcome at distance and near, with minimal dysphotopsia.
