简介:目的探讨基层医院白内障手术从现代囊外摘除术(ECCE)到超声乳化术(phacoemulsification)的过渡.方法对有EccE手术经验的医生,通过130目艮动物实验后,进行100例老年性白内障Phaco带教培训.结果术后1天视力≥0.3者94%,≥0.5者83%;术后3月视力≥0.3者96%,≥0.5者90%,人工晶体植入率100%,无角膜失代偿、核坠落、视网膜脱落等严重并发症,实现了从ECCE到Phaco的安全过渡.结论基层医生只要以严谨、积极的科学态度进行学习,有扎实的显微手术基础,严格选择病例,配以良好的设备,强调规范化操作,同样能成功地完成转化过程,开展较高质量的白内障超声乳化手术.
