简介:目的:利用频域三维相干光学断层扫描(threedimensionalfrequencydomaincoherentopticaltomography,3D-OCT)评估准分子激光原位角膜磨镶术(laserinsitukeratomileusis,LASIK)对视网膜神经纤维层厚度(retinalnervefibrelayerthickness,RNFLT)的影响。方法:对83例83右眼接受LASIK治疗的受试者分别于术前及术后1d;1wk;1,3mo行3D-OCT检查,测量视乳头上方、下方、鼻侧、颞侧及12个钟点位RNFLT,利用重复测量方差分析及配对t检验对术前及术后的数据统计学处理。结果:术前及术后各时间点行重复测量方差分析显示,视乳头下方、颞侧、5:00~11:00位RNFLT均值无显著差异(P〉0.05),而视乳头上方、鼻侧、1:00~4:00位、12:00位RNFLT有显著差异(P〈0.05);进一步对术前及术后各时间点视乳头上方、鼻侧、1:00~4:00位、12:00位RNFLT分别行配对t检验得出,术后1d时视乳头上方、鼻侧及1:00~4:00位、12:00位RNFLT较术前变薄,差异有统计学意义(P〈0.05),术后1wk;1,3mo时以上各方位RNFLT较术前比较均无统计学差异(P〉0.05)。同时表明RNFLT变薄与屈光度及激光时间成正相关。结论:LASIK术后早期上方及鼻侧RNFLT变薄,但术后1wk恢复至正常水平,LASIK手术对RNFLT无长远影响。
简介:目的以接受免费白内障手术的患者电话随访结果为依据,对我省防盲项目完成效果进行评价、分析,探讨提出加强和完善基层医院眼科参与大规模防盲项目患者的可持续随访体系。方法通过以电话随访的方式,对2012年云南省'光明工程'6万例免费白内障手术患者中随机抽取2000例患者就手术视力提高程度及满意度进行电话随访。随访统一使用云南省卫生厅《2012年云南省'光明工程'患者电话随访表》,由专人于4周内完成电话随访。结果患者术后视力明显提高者占90.20%;患者对术后满意度达93.27%;从生活不能自理到能自理占86.41%;术后生活质量明显提高占85.79%;术后患眼有不适者占17.76%;知道如出现不适如何处理的患者占70%;新农合占93.81%,居民医保5.56%,职工医保1.64%,其他医保占0.88%;所有患者均为免费手术,无自付比例。结论在基层开展大规模集中白内障防盲项目的过程中,在严格监控患者术后质量、手术费用、住院天数、降低患者的医疗费用的同时,更应该加强对手术患者的长效管理机制,建立合理的患者随访体系,总结经验,不断完善工作流程,真正改善患者的生活质量,提高患者满意度,体现防盲工作的真正含义。
