摘要
目的:研究LASIK术后早期泪膜及眼表变化对屈光回退的影响。方法:47例(92眼)近视患者行LASIK术,观察术前,术后1天,1周,2周,1月,3月,患者的干眼症状,测量泪液分泌量(Schirmer Ⅰ),泪膜破裂时间(BUT),眼表荧光素染色(Fl),眼表规则指数(SRI),不对称指数(SAI),残留屈光度。分组:是否出现屈光度回退分为屈光回退组和无屈光回退组,对上述数据进行统计分析。结果:LASIK术后1-3月18%的患者出现不同程度屈光回退,与术前泪液分泌量减少、术后3月F1增加、术后2周、1月、3月的SRI的增加及术后1周SAI的增加密切相关(P<0.05)。结论:LASIK术后泪膜及眼表的变化与术后屈光回退密切相关。
Objectives：To study the effect on the earlier change of tear film and ocular surface to refractive regression after LASIK. Methods：47 patients（92 eyes ）were underwent LASIK. The eyes were observed for subjective complaints of dry eye, F1, BUT, schirmers I Test, SAI, SRI preoperatively and 1 day,1 week, 1 month,3 months postoperatively. Groups：92 eyes were divided into refractive regression group and no refractive regression group, All above data experienced statistical analysis. Results： 18% eyes were experienced refractive regression during 1-3 months postoperatively, which were related to the decease of Schirmers I test preoperatively, the increase of SRI at 2 weeks, 1 month,3 months postoperatively, the increase of SRI at 1 weeks postoperatively. Conclusions：The changes of tear film and ocular surface were associated with refractive regression.
