简介:目的:评价VisuMax飞秒激光与MoriaOneUse-PlusSBK角膜板层刀制作超薄角膜瓣的舒适性与安全性。方法:回顾性病例系列研究。统计同期接受角膜屈光手术的778例1556眼(VisuMax飞秒激光组即A组384例768眼,SBK角膜板层刀组即B组394例788眼),对比术中舒适度评分、角膜瓣相关并发症、角膜瓣切口出血、球结膜下出血的发生率,评价两种方法的舒适性与安全性。结果:术中舒适度方面,感觉极不舒适,难以忍受者A组5例(1.3%),B组28例(7.1%);术中角膜瓣切口出血A组4眼(0.5%),B组74眼(9.4%);球结膜下出血A组18眼(2.3%),B组82眼(10.4%);角膜瓣边缘不齐A组0眼(0),B组94(11.9%);A组有4眼(0.5%)出现角膜瓣上皮部分剥脱,但未影响成功掀瓣及手术,A组有53眼(6.9%)发生角膜层间气泡(OBL)。两组无其它相关并发症。结论:两种方法安全可靠,均无严重影响术后视觉质量的角膜瓣相关并发症。
简介:随着研究生招生观念的转变,招收的医学临床专业学位研究生的比重越来越大,对专业型研究生的培养也越来越注重实用。我们在眼科专业型研究生临床培养中,增加病房临床实践时间,特别注重典型病例的示范作用,每一个专业组都会结合自己专业的特点,将典型病例的特点从各个角度展示给广大研究生们,培养其临床诊治思辨能力,培训其显微手术技巧,从临床病历书写到记录总结,结合文献复习,拓展知识结构,锻炼专业型研究生论文书写能力,并以典型病例为基础,扩展知识覆盖面,引申注意事项及特殊病例的诊治。这套严格的培养体系,使专业型研究生能举一反三,从典型病例、重点病例中获取对该种病情的最直观的全景了解与熟悉,以最少的时间掌握最多的临床知识,丰富临床经验,为将来工作岗位中的考核打下基础。
