PURPOSE: To compare intraocular lens (IOL) formula prediction accuracy for patients with previous scleral buckling surgery.
SETTING: Single academic center in Los Angeles, California.
DESIGN: Retrospective study.
METHODS: Patients who had cataract extraction after scleral buckle surgery from 2014 to 2024 were included. The spherical equivalent prediction error (SEQ-PE) from Barrett Universal II (BUII), Hoffer QST, Holladay 1, Kane, Radial Basis Function (RBF) 3.0, and SRK/T was evaluated. The Wang-Koch-adjusted axial lengths were used for eyes >25.0 mm for the Holladay 1 and SRK/T formulas. Analysis was performed with Eyetemis, an online software designed to compare the accuracy, precision, and trueness of the SEQ-PE.
RESULTS: 79 eyes from 77 patients were included. The 6 formulas showed similar accuracy, with no statistically significant differences for pairwise comparisons of the absolute SEQ-PE, which ranged between 0.33 diopters (D) (±0.52 D) for the Holladay 1 and 0.42 D (±0.56 D) for the RBF 3.0 formulas, and for pairwise comparisons of the precision of SEQ-PE, except for the comparison between BUII and Hoffer QST. There was no significant difference in the absolute SEQ-PE within ±0.25 D, ±0.50 D, ±0.75 D, and ±1.00 D. Comparing the trueness of the SEQ-PE, BUII and Hoffer QST were hyperopic, while Holladay 1 and SRK/T were myopic.
CONCLUSIONS: The formulas compared had similar accuracy of the absolute and precision SEQ-PE for eyes with scleral buckles. There was variability in the trueness of the 6 formulas, however. Therefore, surgeons should consider these trends for IOL selection in eyes with scleral buckles.
