摘　　要：目的:探讨白内障合并高度近视经超声乳化术治疗后视力矫正的预测因子。方法:以我院2018年4月—2020年8月经超声乳化术治疗的83例(92眼)白内障合并高度近视患者作为研究对象,以术后6个月最佳矫正视力≥0.3为术后正常视力标准:分为低视力组和正常视力组,对两组患者术前临床资料进行统计学分析。结果:Logistic回归分析显示术前眼轴长度增加、近视病程延长、术前角膜散光度增加以及术前黄斑中心凹厚度减少是术后低视力的独立影响因素(P<0.05),其中术前眼轴长度、近视病程、术前角膜散光度以及术前黄斑中心凹厚度均对术后低视力发生有预测价值(P<0.05),当术前眼轴长度≥29.69mm、近视病程≥38.28年、术前角膜散光度≥1.412D以及术前黄斑中心凹厚度≤171.28μm时敏感度和特异度最高。结论:对于白内障合并高度近视患者术前综合评估患者的眼轴长度、角膜散光度以及黄斑中心凹厚度有助于预判术后视力矫正水平,从而为优化治疗方案提供依据。Objective:To investigate the predictive factors of vision correction after phacoemulsification for cataract complicated with high myopia.Methods:In our hospital from April 2018 to August 2020 menstruation phaco treatment of 83 cases(92 eyes)of cataract with high myopia patients as the research object,with the postoperative best corrected visual acuity 0.36 months for normal vision after standard:divided into low vision group and normal vision,on two groups of patients with preoperative clinical data for statistical analysis.Results:Logistic regression analysis showed that increased axial length before operation,prolonged myopia course,increased corneal dispersion and decreased macular fovea thickness before operation were independent influencing factors of low visual acuity after operation(P<0.05).Among them,preoperative axial length,myopia course,preoperative corneal divergence and preoperative macular fovea thickness all had predictive value for the occurrence of postoperative low vision(P<0.05).The highest sensitivity and specificity were obtained when the preoperative axial length≥29.69mm,myopia duration≥38.28years,preoperative corneal dispersion≥1.412D,and preoperative fovea thickness≤171.28μm.Conclusion:For cataract patients with high myopia,preoperative comprehensive evaluation of axial length,corneal dispersion and macular fovea thickness is helpful to predict the level of postoperative visual acuity correction,so as to provide a basis for optimal treatment plan.
