Relationship between ocular biological parameters and corneal higher-order aberrations in cataract patients
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-resto-ring procedures to refractive surgeries,the demand for better postoperative visual quality has become increas-ingly 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 thick-ness,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 cor-related 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 shal-low 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 predic-ting postoperative visual outcomes and optimizing individualized treatment for cataract surgery.(I nt Rev Oph-thalmol,2024,48:416-419)
