摘要 角膜地形图引导的准分子激光角膜屈光手术,主要用于角膜外伤、手术和疾病导致的严重高阶像差以及先天性角膜不规整的治疗,随着设备性能与技术的提高,手术适应范围在不断扩大,尽管角膜屈光力占全眼屈光力2/3以上,但毕竟不是全眼的总体屈光状态,因此与常规手术相比,其手术设计存在着明显的特殊性。因此,了解其手术特点,理解手术设计原则,把握手术适应证是开展该项技术相关医技人员应该掌握的内容。 Corneal topography-guided excimer laser refractive surgery (topo-guided) has been proven to be an effective and safe method to treat irregular corneal astigmatism, which is usually induced by ocular trauma, refractive surgery complications or some corneal diseases. With the development of technology and the improvement of device performance, the indications of topo-guided excimer laser refractive surgery have been expanded. However, the objective of topo-guided is to make the cornea more regular, without taking the aberrations of the whole eye into consideration. Compared to other routine procedures, topo-guided exeimer laser sugery has its own characteristics, which should be understood and considered when planning for surgery in order to achieve better performance outcomes.
