Abstract: The visual outcomes of cataract surgery are significantly influenced by preoperative ocular biometric parameters and corneal higher-order aberrations. As cataract surgery transitions from vision-restoring procedures to refractive surgeries, the demand for better postoperative visual quality has become increasingly stringent. This review explores the relationship between ocular biometric parameters (such as central corneal thickness, corneal refractive power, anterior chamber depth, anterior chamber angle, lens thickness, pupil size, and axial length) and corneal higher-order aberrations. The central corneal thickness is negatively correlated with total higher-order aberrations, spherical aberration, and coma, but positively correlated with trefoil aberration. Corneal refractive power affects higher-order aberrations, with myopic patients showing lower total higher-order aberrations, while hyperopic patients show higher values. The influence of anterior chamber depth on higher-order aberrations is controversial, with some studies indicating that a shallow anterior chamber increases corneal spherical aberration. An increase in pupil size is associated with an increase in higher-order aberrations. Additionally, axial length is negatively correlated with total corneal higher-order aberrations and spherical aberration. Accurate measurement of these parameters aids in predicting postoperative visual outcomes and optimizing individualized treatment for cataract surgery.(Int Rev Ophthalmol, 2024, 48:  416-419)
