Abstract

We investigated the characteristics of corneal higher-order aberrations in patients with simple cataract. Corneal topographic analysis was retrospectively reviewed in 149 consecutive eyes before simple cataract surgery. The corneal total higher-order aberrations (HOAs) for a 4-mm diameter, difference between central corneal power and simulated K readings (ΔK), corneal spherical aberration for a 6-mm diameter (Z40), and corneal cylinder were measured. Reliable topographic measurements for a 6-mm diameter were obtained for 78 % of eyes. In such reliable measurements, the mean ± standard deviation total HOA was 0.162 ± 0.067 μm; in 5 % of eyes the total HOAs exceeded 0.3 μm. In 3 % of eyes, the ΔK (mean, 0.16 ± 0.17 diopter [D]) exceeded 0.5 D. In 11 % of eyes, the Z40 (mean, 0.247 ± 0.135 μm) was below 0.1 μm. In 18 % of eyes, the cylinder (mean, 1.04 ± 0.8 D) exceeded 1.5 D. Our results suggested that eyes with clinically significant irregular astigmatism, spherical aberration, or regular astigmatism were included even in simple cataract candidates in addition to the existence of eyes where reliable evaluation of corneal topography was not possible. Assessing corneal topography preoperatively may aid in the selection of new technology IOLs to avoid potential problems in eyes with suboptimal optics.
