Abstract

Purpose: To investigate the accuracy of a new optical biometer for intraocular lens (IOL) power calculation in eyes undergoing cataract surgery. Methods: Consecutive eyes of patients undergoing cataract surgery with the same IOL model were enrolled in a prospective cohort study. Results: Seventy-four eyes of 74 cataract patients were enrolled. The MedAE was 0.25 D with all formulas. A PE within ±0.50 D was obtained in 89.04% of cases with the Hoffer Q and SRK/T formulas, and in 87.67% of cases with the Holladay 1 formula. Conclusions: The optical biometer investigated in the present study provides accurate measurements for IOL power calculation.
