Anterior segment optical coherence tomography (AS-OCT) is emerging as a valuable tool for in vivo ocular biometry. This study constitutes the first known attempt at in vivo assessment of crystalline lens curvature using AS-OCT technology. METHODS: An ASOCT phakometry protocol was compared to video-based phakometry data on a sample of 42 children. RESULTS: AS-OCT phakometry demonstrated poor 95% limits of agreement (LOA) and significant magnitude bias, yielding excessively flat radii when used to measure flatter surfaces (anterior: P < 0.001, LOA = -8.82 to +6.52 mm; posterior: P < 0.001, LOA = -1.13 to +1.67 mm). Orthogonal regression-derived correction neutralized the posterior surface magnitude bias only (P = 0.206, LOA = -0.78 to +0.83 mm). CONCLUSIONS: AS-OCT phakometry of the anterior lens surface compared poorly to video-based methods, likely due to errors introduced by nonrepeatable locations for the cross-sectional scans through the crystalline lens.
