Résumé
To evaluate refractive error after cataract surgery using an optical biometer equipped with anterior segment optical coherence tomography (AS-OCT). Chukyo Eye Clinic, Nagoya, Japan. Retrospective observational design. In total, 150 patients with cataract (150 eyes, mean age 73.4 ± 8.2 years, men 76, women 74), who underwent measurement of parameters with the AS-OCT scanners ANTERION (AS-OCTB) and IOLMaster 700 (OCTB) before cataract surgery, were enrolled in the study. Refractive prediction error was compared between the 2 devices using the SRK/T, Haigis, and Barrett Universal II (UII) formulas for intraocular lens (IOL) power calculation. There were significant differences between AS-OCTB and OCTB in axial length, mean corneal refractive power, anterior chamber depth, lens thickness, and corneal diameter (n = 150). In the SRK/T formula, the arithmetic means of refractive prediction errors for AS-OCTB and OCTB were -0.06 ± 0.46 diopters (D) and 0.02 ± 0.42 D, respectively. In the Haigis formula, the arithmetic means of refractive prediction errors for AS-OCTB and OCTB were -0.23 ± 0.40 D and -0.08 ± 0.35 D, respectively. In the Barrett UII formula, the arithmetic means of refractive prediction errors for AS-OCTB and OCTB were -0.02 ± 0.38 D and 0.11 ± 0.36 D, respectively. AS-OCTB showed significantly larger refractive prediction error toward myopia than OCTB in all 3 formulas (P < .0001). The refractive prediction error using AS-OCTB showed a small difference from that using OCTB. While clinically comparable, the 2 methods could drive meaningful differences in IOL selection.
