摘要
目的观察有晶状体眼后房型人工晶状体(ICL)矫正高度近视的临床效果。方法回顾性分析2017年12月至2018年9月接受ICL植入术高度近视(-6.00 D^-18.00 D)55例(110眼)的临床资料。术后随访3个月,观察分析各项指标。结果术后3个月平均裸眼视力、最佳矫正视力(Log MAR)及屈光度与术前对比,差异均有统计学意义(t=14.580、13.240、11.770,P=0.010、0.021、0.013)。术后3个月总体低阶像差均方根值与术前对比差异有统计学意义(t=-18.780,P=0.000)。术后3个月总体高阶像差、3阶像差、4阶像差和5阶像差均方根值与术前对比差异均无统计学意义(t=-1.278、0.785、0.351、0.457,P=0.125、0.412、0.224、0.324)。术后3个月球差(Z4^0)、水平彗差(Z3^1)、垂直彗差(Z3^-1)、水平三叶草(Z3^3)和垂直三叶草(Z3^-3)均方根值与术前对比差异均无统计学意义(t=0.654、0.545、0.387、0.268、0.578,P=0.547、0.371、0.241、0.187、0.428)。结论ICL矫正高度近视具有有效性、安全性、可预测性及稳定性,术后视觉质量良好。
Objective To observe the clinical efficacy of posterior chamber phakic intraocular lens(ICL)for correction of high myopia.Methods The data of 110 eyes of 55 cases with high myopia(-6.00 D--18.00 D)who received ICL implantation from Dec.2017 to Sep.2018 were collected and analyzed retrospectively.The patients were followed up for 3 months.The data were observed and analyzed between preoperative and postoperative.Results The differences of the average uncorrected visual acuity,best corrected visual acuity(LogMAR)and refraction were statistically significant between preoperative and 3 months postoperatively(t=14.580,13.240,11.770,P=0.010,0.021,0.013).There was significant difference of the root mean square value in the general lower-order aberrations between preoperative and 3 months postoperatively(t=-18.780,P=0.000).The differences in the general higher-order aberrations,3-order aberrations,4-order aberrations,and 5-order aberrations root mean square value were not statistically significant between preoperative and 3 months postoperatively(t=-1.278,0.785,0.351,0.457,P=0.125,0.412,0.224,0.324).The differrences of Z4^0,Z3^1,Z3^-1,Z3^3,Z3^-3 were not statistically significant between preoperative and 3 months postoperatively(t=0.654,0.545,0.387,0.268,0.578,P=0.547,0.371,0.241,0.187,0.428).Conclusion Posterior chamber phakic intraocular lens is safe,effective,predictable and stable for correction of high myopia and postoperative visual quality is good.
