METHODS: A total of 40 participants were recruited and randomly divided into two groups. Group one was instructed to wear bandage contact lenses for a week and use antibiotic eye drops for a month since the first day after surgery. Group two received sub-conjunctival injection of tobramycin and was asked to wear eye pads on the first day after surgery and then were instructed to use antibiotic eye drops as the first group did. Ocular surface disease index(OSDI) questionnaire, slit-lamp microscope examination of tear break-up time(TBUT), corneal fluorescein score(CFS), tear meniscus height(TMH) together with anterior segment optical coherence tomography(AS-OCT) and corneal topography were evaluated preoperatively and postoperatively. RESULTS: The subjective feeling(P=0.004), TBUT(P〈0.001) and TMH(P=0.02) post-surgery had improved in patients who used bandage contact lenses compared with those who did not at 1wk post-surgery. Until three month postoperatively, the comfort degree(P=0.004) and TMH(P=0.01) of group two were still worse than group one. Moreover, TBUT(P〈0.001) and CFS(P=0.004) of the group with eye pads got worse than the results before, whereas the group with bandage contact lenses recovered to normal. None of these patients had infections or other complications. CONCLUSION: Wearing therapeutic bandage contact lens after cataract surgery, compared with traditional eye-pads, is a safe method to improve tear-film stability and reduce post-operative discomfort without hindering corneal incision recovery.展开更多
目的:探讨2型糖尿病患者眼表状态的改变。方法:107例(107眼)2型糖尿病患者(DM组)及100例100只正常眼(对照组),观察分析两组患者主观感觉,基础泪液分泌试验(schirmerI test,SIt),泪膜破裂时间(tear breaking up time,BUT)测定角膜荧光素...目的:探讨2型糖尿病患者眼表状态的改变。方法:107例(107眼)2型糖尿病患者(DM组)及100例100只正常眼(对照组),观察分析两组患者主观感觉,基础泪液分泌试验(schirmerI test,SIt),泪膜破裂时间(tear breaking up time,BUT)测定角膜荧光素染色及结膜印迹细胞学状态改变。结果:DM组患者发生干眼的几率(54.2%)较对照组(17.0%)明显增高,差异具有统计学意义。DM组基础泪液分泌试验(8.48±4.34mm)较对照组(13.73±4.79mm)降低,BUT(6.78±4.08s)较对照组(14.31±4.78s)明显缩短,角膜荧光素着色点(19.6%)较对照组(6.0%)明显增多,差异具有显著意义(P<0.05);结膜印迹细胞学检查DM组结膜杯状细胞密度平均值(80.03±40.38/mm2)较对照组(132.14±33.01/mm2)明显降低,结膜鳞状化生级别较对照组增高,两组差异有统计学意义(P<0.01)。结论:糖尿病可引起角膜、结膜状态的改变。对于糖尿病患者尤其是在各种手术时要充分考虑眼表的改变,给予恰当的治疗。展开更多
