目的:比较高度近视合并白内障超声乳化吸除分别植入3种不同人工晶状体(intraocular lens,IOL)的临床效果。方法:回顾性系列病例研究。回顾性分析高度近视合并白内障患者68眼行超声乳化白内障吸除联合IOL植入术后3mo的随访资料。患者分别植入一体三襻式亲水性丙烯酸酯IOL(Bigbag,Zeiss)、一体C形襻亲水性丙烯酸酯IOL(620H,Rayner)、一体C形襻亲水性丙烯酸酯IOL(HQ201-hep)。使用Pentacam三维眼前节测量系统采集各眼Scheimpflug图像,测量散瞳后前房深度,使用Image-pro plus6.0图像分析得出IOL的倾斜度和偏心值。检测术后IOL眼实际屈光度与靶屈光度差异。满足正态分布和方差齐性的行单因素方差分析,采用SNK-q检验进行组间两两比较。结果:三组间前房深度比较有统计学意义(F=50.74,P<0.05)。实际屈光度与靶屈光度的误差,3组比较无统计学意义(F=1.391,P>0.05)。IOL偏位值与倾斜度在水平和垂直方向上的数值差异均无统计学意义(P>0.05)。未见后囊膜混浊、黄斑水肿、视网膜脱离发生。结论:三种不同IOL均可用于高度近视合并白内障患者,但各有其优越性和局限性。

AIM:To compare clinical effects of cataract with high myopia patients implanted three different kinds of intraocular lens(IOL).METHODS:Sixty-eight cataract with high myopia eyes undertook phacoemulsification and IOL implantation,including three different kinds of IOL.1-piece hydrophilic acrylic IOL(Bigbag,Zeiss);1-piece hydrophilic acrylic IOL(620H,Rayner);and 1-piece hydrophilic acrylic IOL(HQ201-hep).Anterior chamber depth after mydriasis,tilt and deviation of IOL were measured using Scheimpflug system(Pentacam,Oculus) and analyzed with Image-pro plus 6.0 software.RESULTS:Comparison of the anterior chamber deepth among the three groups was statistically significant(F=50.74,P<0.05).Difference between postoperative actual refraction and target refraction was not statistically significant(F=1.391,P>0.05).Deviation and tilt of IOL among the three groups showed no statistical significance(P>0.05).No eyes were detected posterior capsule opacification,macula edema and retinal detachment.CONCLUSION:Three different kinds of IOL can be implanted for cataract patients with high myopia,but each has its advantages and limitations.
