目的 探讨飞秒激光和角膜板层刀制作角膜瓣的准分子激光原位角膜磨镶术(LASIK)术前术后半年内泪膜稳定性的变化情况及对比分析.方法 78例(156只眼)接受LASIK矫正近视者,依受术者要求分为飞秒组和板层刀组,分别观察两组术前、术后不同时间段的主观症状、泪液分泌实验、角膜荧光素染色评分和泪膜破裂时间(BUT).结果 两组泪液分泌量在术后3个月内,差异有统计学意义(t=3.125,P＜0.05),术后6个月差异无统计学意义(t=0.014,P＞0.05).两组BUT比较,术后3个月内差异有统计学意义(t=0.579,P＜0.05),术后6个月BUT差异无统计学意义(t =0.310,P＞0.05).角膜荧光素染色,术后1个月内两组差异有统计学意义(t=0.741,P＜0.05),术后3个月、6个月差异无统计学意义(t=0.017,P ＞0.05).结论 两组术后早期泪膜稳定性均下降.飞秒组术后干眼症状轻,恢复快.两组术后短期内出现的干眼多在6个月时恢复正常.
目的 探討飛秒激光和角膜闆層刀製作角膜瓣的準分子激光原位角膜磨鑲術(LASIK)術前術後半年內淚膜穩定性的變化情況及對比分析.方法 78例(156隻眼)接受LASIK矯正近視者,依受術者要求分為飛秒組和闆層刀組,分彆觀察兩組術前、術後不同時間段的主觀癥狀、淚液分泌實驗、角膜熒光素染色評分和淚膜破裂時間(BUT).結果 兩組淚液分泌量在術後3箇月內,差異有統計學意義(t=3.125,P＜0.05),術後6箇月差異無統計學意義(t=0.014,P＞0.05).兩組BUT比較,術後3箇月內差異有統計學意義(t=0.579,P＜0.05),術後6箇月BUT差異無統計學意義(t =0.310,P＞0.05).角膜熒光素染色,術後1箇月內兩組差異有統計學意義(t=0.741,P＜0.05),術後3箇月、6箇月差異無統計學意義(t=0.017,P ＞0.05).結論 兩組術後早期淚膜穩定性均下降.飛秒組術後榦眼癥狀輕,恢複快.兩組術後短期內齣現的榦眼多在6箇月時恢複正常.

Objective To compare the changes of tear film stability between femtosecond laser created flap and mechanical microkeratome corneal flap in excimer laser in situ keratomileusis (LASIK) before and after operation.Methods Seventy-eight cases of correctional myopia (156 eyes) were randomly divided into two groups:femtosecond laser created flap group and mechanical microkeratome created flap group.The preoperative,postoperative subjective symptoms,Schirmer test,corneal fluorescein staining scores and BUT in two groups were observed.Results The tear secretion volume of two groups were compared at 3 months after the operation,the difference had statistical significance (t =3.125,P ＜ 0.05),the result at 6 months after the operation had no statistical significance (t =0.014,P ＞ 0.05).About the comparision of the BUT between these two groups,the result at 3 months after the operation had statistical significance (t =0.579,P ＜ 0.05),the difference had no statistical significance after 6 months (t =0.310,P ＞ 0.05).About the corneal fluorescein staining,the difference at 1 months after the operation had statistial significance (t =0.741,P ＜ 0.05),it had no statistical significance at 3 months (t =0.017,P ＞ 0.05).Conclusion The early stability of tear film decrease after operation in both of the two groups.The dry eye symptoms are lighter and recove faster in the femtosecond laser flap group.The dry eye symptoms can be restored to normal about at 6 months after the operation in both two groups.
