Accuracy of 7 intraocular lens power calculation formulas in primary angle-closure glaucoma eyes, according to axial length and anterior chamber depth.

ABSTRACT:

Purpose

To assess the impact of Axial Length (AL) and anterior chamber depth (ACD) on the performance of the Kane, EVO 2.0, Barrett Universal II (BU II), SRK/T, Haigis, Holladay 2 and Hoffer Q formulas when calculating intraocular lens power in primary angle-closure glaucoma (PACG) patients.

Setting

Eye hospital, Wen Zhou Medical University, Zhejiang, China.

Design

Retrospective, consecutive case series.

Methods

Patients who underwent cataract surgery diagnosed with PACG or not were included. The main outcome measures comprised mean prediction error (ME), mean absolute refractive error (MAE), median absolute refractive error (MedAE). Additionally, the proportions of eyes with postoperative refractive errors within ± 0.25 diopter (D), ± 0.50 D, ± 0.75 D, and ± 1
