摘　　要：白内障手术视觉结果受到术前眼生物学参数和角膜高阶像差的影响。随着白内障复明手术向屈光手术的转变,对术后视觉质量的需求提高。本文综述了眼部生物学参数(中央角膜厚度、角膜屈光力、前房深度、前房角、晶状体厚度、瞳孔大小、眼轴长度)与角膜高阶像差之间的关系。中央角膜厚度与总高阶像差及球差、慧差呈负相关,而与三叶草差呈正相关。角膜屈光力影响高阶像差,近视患者的总高阶像差较低,远视患者则较高。前房深度对高阶像差的影响存在争议,部分研究显示浅前房增加角膜球差。瞳孔扩大与高阶像差的增加相关。眼轴长度与角膜总高阶像差及球差呈负相关。精准测量眼生物学参数有助于预测术后视觉效果,优化白内障手术的个体化治疗。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.
