简介：目的分析个性化角膜切口对白内障术后角膜散光及裸眼视力的影响。方法90例（106眼）白内障患者分为2组，试验组选择位于角膜最大屈光度径线上透明角膜切口，对照组选择11：00处的透明角膜切口，行白内障超声乳化人工晶状体植入术。术前及术后1周、1个月、3个月分别检测患者角膜散光及视力情况。结果术后1个月和3个月试验组裸眼视力分别为（4．9±0．15）、（5．0±0．15），显著优于对照组的（4．8±0．18）、（4．8±0．20），差异有统计学意义（P〈0．05）。术后1个月和3个月试验组角膜散光度分别为（0．78±0．39）、（0．79±0．40），明显低于对照组的（1．53±0．32）、（1．52±0．28），差异有统计学意义（P〈0．05）。结论白内障患者术前大多存在〈1．5D的角膜散光。采用个性化角膜切口可降低白内障手术角膜源性散光，术后视力恢复好，是一种简便、可行的手术切口。（中国眼耳鼻喉科杂志，2013，13：168—169，172）

简介：目的评价甲基纤维素联合透明质酸钠制作软壳技术在白内障小切口非超声乳化手术中的效果.方法白内障“复明工程”患者261例295眼.随机分为A、B两组,其中A组术中单用透明质酸钠,B组术中联合使用甲基纤维素和透明质酸钠.手术方法为小切口非超声乳化加人工晶体植入.结果术后第ld裸眼视力大于0.3者,A组78.79％（104/132）,B组87.1％（142/163）,两组之间差异显著（P＜0.05）；术后第7d视力在0.3以上者,A组93.9％（124/132）,B组94.5％（154/163）.两组间差异无统计学意义（P＞0.05）.术后角膜水肿情况：术后第1天,A组17.42％（23/132）,B组9.8％（16/163）,两组间比较差异有统计学意义（P＜0.05）.术后第7天,A组2.27％（3/132）,B组2.45％（4/163）,两组间比较差异无统计学意义（P＞0.05）.结论甲基纤维素联合透明质酸钠制作软壳技术比单用透明质酸钠更安全.
