Purpose: To compare ocular biometry measured using 4 applanation ultrasonographic biometry devices and evaluate the accuracies of the refractive outcomes after cataract surgery. Methods: A total of 60 eyes in 60 patients who received cataract surgery were included in the present study. The axial length was measured using applanation ultrasonographic biometry devices (Aviso?, Hi-Scan<SUP>Ⓡ, UD-6000<SUP>Ⓡ, P37-II<SUP>Ⓡ). Additionally, keratometry was measured using an autokeratometer (Topcon KR 8000) and the SRK/T formula was used to calculate intraocular lens (IOL) power. Two months after cataract surgery, the refractive outcome was determined, and results from the 4 different applanation ultrasonographic biometry devices were compared. Results: Axial lengths were 23.52 ± 1.45 mm, 23.51 ± 1.04 mm, 23.54 ± 1.58 mm, and 23.52 ± 1.38 mm measured using Aviso<SUP>Ⓡ, Hi-Scan<SUP>Ⓡ, UD-6000<SUP>Ⓡ, and P37-II<SUP>Ⓡ, respectively with no statistically significant differences observed (p = 0.92). The mean absolute error (MAE) of the Aviso<SUP>Ⓡ, Hi-Scan<SUP>Ⓡ, UD-6000?, and P37-II<SUP>Ⓡ was 0.41 ± 0.32 diopter (D), 0.40 ± 0.30 D, 0.36 ± 0.26 D, and 0.39 ± 0.26 D, respectively. The mean numerical error (MNE) was 0.39 ± 0.37 D, 0.36 ± 0.32 D, 0.26 ± 0.29 D, and 0.38 ± 0.32 D, respectively. The differences between the 4 different applanation ultrasonographic biometry devices were not statistically significant (<EM>p</EM> = 0.90, <EM>p </EM>= 0.81). Conclusions: The ocular biometric measurements and prediction of postoperative refraction using Aviso<SUP>Ⓡ, Hi-Scan?, UD-6000<SUP>Ⓡ, P37-II<SUP>Ⓡ showed no significant differences.
