YAG激光行后囊膜切开术后术眼屈光状态的改变

目的探讨YAG激光行人工晶状体后囊膜切开术对术眼屈光状态的影响。方法收集我院73例(86眼)行YAG激光人工晶状体后囊膜切开术患者,比较术前术后屈光状态的改变。结果术后术眼屈光状态无改变者5眼;术后较术前增加+0.25d至+0.50d者13眼;较术前增加+0.75d至+1.00d者22眼;较术前增加+1.25d至+1.50d者27眼;较术前增加+1.75d至+2.00d者12眼;较术前增加+2.00d以上者7眼。结论 YAG激光行人工晶状体后囊膜切开术后术眼有发生远视性漂移倾向。

Objective To explore the influence of ocular refractive state after YAG laser IOL posterior capsulotomy. Methods Collect patients that accept YAG laser IOL posterior capsulotomy in our hospital 73 ca- ses（ 86 eyes）, and compare preoperative and postoperative refractive change. Results 5 eyes refractive state without change compared with preoperative,13 eyes refractive state increase from ＋0. 25 d to ＋0. 50 d com- pared with preoperative,22 eyes refractive state increase from ＋ 0. 75 d to ＋ 1.00 d compared with preopera- tive ,27 eyes refractive state increase from ＋ 1.25 d to ＋ 1.50 d compared with preoperative, 12 eyes refractive state increase from ＋ 1.75 d to ＋ 2. 00 d compared with preoperative ,7 eyes refractive state increase more than ＋ 2. 00 d compared with preoperative. Conclusion The ocular refractive state tend to hyperopic drift occurs after YAG laser IOL posterior capsulotomy.
