To evaluate the visual performance of patients implanted with a new bi-aspheric, +3-D nonblended segment, multifocal IOL.
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.
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.
This new aspheric, segmented IOL provides a good visual outcome at distance and near, with minimal dysphotopsia.
