摘要
目的观察近视眼LASIK手术后调节幅度的变化情况。方法37例近视患者平均年龄（29．1±2．4）岁，LASIK手术前及术后1周和1月分别用移近法和负镜片法测量单眼的调节幅度，采用t检验分析手术前后调节幅度的变化。结果术前平均等效球镜度（-6．38±1．23）D。术前推进法和负镜片法测的调节幅度为（8．32±2．1）D和（5．86±1．74）D，术后1周两种方法测得的调节幅度分别为（6．54±1．82）D和（4．15士1．63）D，与手术前相比差异均有统计学意义（P均〈0．05）。术后1月调节幅度为（8．24±1．76）D和（5．53士2.28）D，与术前相比差异无统计学意义（P均〉0．05）。结论LASIK手术对近视眼的调节功能有一定影响，近视眼术后调节幅度早期降低，1月后逐渐恢复。
Objective To investigate the changes in the amplitude of accommodation after laser in situ keratomileusis （LASIK） for myopia. Methods Thirty-seven myopic patients （74 eyes） who underwent LASIK were included in the study with the mean age of 29.1±2.4 and the spherical equal of -6.38±1.23D. Amplitude of accommodation was measured monocularly using push-up test and minus lenses to blur before surgery, one week and one month after surgery. Results The amplitude of accommodation was 8.32±2.1D and 5.86±1.74D preoperatively with push-up test and minus lenses to blur, 6.54± 1.82 and 4.15± 1.63D one week postoperatively, 8.24±1.76 and 5.53±2.28D one month postoperatively. With the paired t test, there was a significant difference between the preoperative and one-week postoperative amplitude of accommodation （P 〈0.05）. However, there was no significant difference between the preoperative and one-month postoperative amplitude of accommodation （P 〉0.05）. Conclusions The amplitude of accommodation in myopia may drop after LASIK in the early stage and gradually recover in about one month.
