摘　　要：目的:探讨选择性手术切口对ICL(有晶状体眼后房型人工晶状体)术后散光控制的作用。方法:高度近视患者102例195眼,随机分成选择性切口组(A组)97眼和颞侧角膜切口组(B组)98眼,通过术前、术后1wk;1,3mo分别行角膜地形图检查,观察患者术后散光的变化。结果:A组术前平均角膜散光为1.26±0.35D,B组术前平均角膜散光为1.28±0.38D,两组差异无统计学意义。A组术后1wk;1,3mo的平均散光分别为0.93±0.29,0.85±0.16,0.80±0.13D;B组术后1wk;1,3mo的平均散光分别为1.32±0.33,1.27±0.18,1.25±0.20D,两组差异有统计学意义。结论:选择性手术切口能在一定程度上控制ICL术后散光。AIM： To evaluate the effect of the chosen incision on corneal astigmatism after implantable collamer lens（ICL）surgery.METHODS： The study included 195 eyes of 102 patients, and all eyes were randomly divided into two groups： the chosen incision group（Group A, 97 eyes）and temporal corneal incision（Group B, 98 eyes）. Before the operation, and 1wk,1mo and 3mo after the operation, each patient was examined with corneal topography to observe the changes of corneal astigmatism. RESULTS： Preoperative corneal astigmatisms were（1.26±0.35）D in group A and（1.28±0.38）D in group B, thus there was no statistically significant difference（P〉0.05）. One week postoperatively, the astigmatism were（0.93±0.29）D in group A and（1.32±0.33）D in group B. One month postoperatively, the astigmatism were（0.85±0.16）D in group A and（1.27±0.18）D in group B. Three months postoperatively, the astigmatism were（0.80±0.13）D in group A and（1.25±0.20）D in group B. The differences between the two groups were statistically significant（P〈0.01）. CONCLUSION： The chosen incision can reduce postoperative astigmatism to a certain extent after ICL surgery.
