目的：探讨高度近视并发性白内障行超声乳化吸出植入Bigbag及MI60两种人工晶体后的早期临床疗效。方法分析该科高度近视并发性白内障行超声乳化吸出并植人工晶体83例（117眼）。其中植入Bigbag人工晶体44例（61眼）为A组，植入MI60人工晶体39例（56眼）为B组。记录两组围手术期相关评价指标：眼轴及前房深度、裸眼视力、最佳矫正视力、对比敏感度、屈光状态、晶体位置、并发症等。结果（1）术后6个月两组前房深度较术前增加，同时组间有统计学意义（P＜0．01）。术后6个月与术前玻璃体腔前后径（视轴区后囊膜至视网膜的距离）的差值：B组（4．51±0．81）mm明显大于A组（2．92±0．79）mm，P＜0．01。（2）两组术后6个月实际屈光度与术前预留屈光度差值：A组≤±1．0D有43眼（70．49％），B组≤±1．0D 有32眼（57．14％）。（3）两组术后裸眼视力较术前改善明显（P＜0．01）；两组术后6个月BCVA（最佳矫正视力）及对比度视力均无统计学意义（P＞0．05），术后主观视觉问卷调查显示A组满意度高于B组。（4）并发症：A组后囊膜混浊4例、玻璃体后脱离2例；B组后囊膜混浊5例、人工晶体偏心1例、玻璃体后脱离5例。结论高度近视性白内障植入特殊设计的Bigbag人工晶体使手术前后前房深度、玻璃体腔前后径的改变较小，预留晶体度数更准确，术后视力提高明显，主观满意度较高。

Objective To discuss and explore the early clinical effects between the Bigbag and MI60 intraocluar lens (IOL)implanta-tion in cataract patients with high myopia.Methods We investigated the clinical data of 83 patients who had received phacoemulsifica-tion and IOL implantation.The patients were divided into two groups:group A (n=44,61 eyes)all used the Bigbag IOL and group B (n=39,56 eyes)all used MI60 IOL.Preoperative and postoperative axial length,anterior chamber depth,visual acuity,BCVA (best corrected visual acuity),contrast sensitivity,refractive status were recorded.Position of the intraoeular lens and postoperative complica-tions were observed.Results (1 )The postoperative anterior chamber increased in two groups than preoperative one,and group B in-creased more significantly than group A (P <0.05).The variations in distance from the posterior capsule membrane to the retina were significantly different between group A (2.92 ±0.79)mm and group B (4.51 ±0.81)mm.(2)The diopter of refractive error 6 months after surgery:43 eyes (70.46%)of bigbag group were within 1.0 D,and 32 eyes (57.14%)of M160 group were within 1.0 D.(3)The postoperative visual acuity of two groups was improved significantly compared with the preoperative (P<0.05),but there was no signif-icant difference on best corrected visual acuilty and curves of contrast sensitivity.Postoperative subjective visual satisfaction in group A was superior to group B.(4)Complications:goup A has 4 cases of capsular opacification and 2 cases of posterior vitreous detachment;group B has 5 cases of capsular opacification,1 case of IOL deviation,and 5 cases of posterior vitreous detachment.Conclusions This clinical research showed Bigbag IOL is more suitable than MI60 IOL in cataract patients with high myopia,which is more effective and safe.
