摘　　要：目的 探讨白内障患者多焦点人工晶状体植入术前后Kappa角变化及与前房深度和瞳孔直径的相关性。方法 选择2022年1月至2024年7月收治的60例(60眼)白内障患者,均行多焦点人工晶状体植入术。对比手术前后Kappa角大小与方向,采用Pearson相关分析手术前后Kappa角与瞳孔直径、前房深度的相关性,采用多重线性回归分析手术前后Kappa角大小影响因素。结果 60例患者术后Kappa角大小与方向均较术前下降,瞳孔直径较术前减小,前房深度较术前增加(P<0.01)。Pearson相关分析,术前Kappa角大小与术前瞳孔直径显著正相关,与术前前房深度显著负相关(P<0.05,P<0.01);术后Kappa角大小与手术前后瞳孔直径显著正相关(P<0.05,P<0.01)。多重线性回归分析,术前Kappa角大小与术前瞳孔直径、术前前房深度均有相关性(P<0.01);术后Kappa角大小与术后瞳孔直径有相关性(P<0.01)。60例中1例出现术后远视觉质量不佳。结论 白内障患者多焦点人工晶状体植入术后Kappa角有下降趋势,Kappa角降低与前房深度和瞳孔直径具有一定关系。Objective To investigate the changes in Kappa angle and its relationship with anterior chamber depth and pupil diameter before and after multifocal intraocular lens(MIOL) implantation in cataract patients.Methods A retrospective analysis was performed on 60 cataract patients(60 eyes) admitted from January 2022 to July 2024,all of whom underwent MIOL implantation.The size and direction of Kappa angle before and after surgery were compared,Pearson correlation analysis was used to analyze the correlation between Kappa angle,pupil diameter and anterior chamber depth before and after surgery,and multiple linear regression was used to analyze the influencing factors of size of Kappa angle before and after surgery.Results The size and direction of Kappa Angle decreased,pupil diameter decreased and anterior chamber depth increased in 60 patients after surgery(P<0.01).Pearson correlation analysis showed that preoperative size of Kappa angle was positively correlated with preoperative pupil diameter and negatively correlated with preoperative anterior chamber depth(P<0.05,P<0.01).There was a significant positive correlation between size of Kappa angle and pupil diameter before and after surgery(P<0.05,P<0.01).Multiple linear regression analysis showed that preoperative Kappa angle was correlated with preoperative pupil diameter and anterior chamber depth(P<0.01).The Kappa angle was correlated with the pupil diameter(P<0.01).Poor distal vision quality was found in 1 of 60 patients.Conclusion The Kappa angle of cataract patients after MIOL implantation has a downward trend.The decrease of Kappa angle has a certain relationship with anterior chamber depth and pupil diameter.
