2、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(2．924-0．79)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≤4-1．0D有43眼(70．49％)，B组≤±1．0D有32眼(57．14％

3、)。(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。关键词：人工晶状体；白内障；高度近视；超声乳化doi：1
