摘要激光角膜屈光手术矫治屈光不正,分为角膜基质内消融术(LASIK、FS-LASIK、SMILE)以及角膜表层(上皮下)消融术(PRK、LASEK、Epi-LASIK、TPRK)两大类.尽管手术的主流为角膜基质内消融术,但表层手术以其操作的安全性、术后角膜生物力学的完整性、无角膜瓣相关并发症等优势,仍然具有旺盛的生命力.当前,对于激光角膜表层手术所需解决的主要问题,是术后早期的眼部疼痛反应以及晚期的角膜上皮下混浊(haze)及伴随的屈光回退.围手术期选择应用合理的非甾体类抗炎滴眼液,可显著减轻术后的疼痛反应及刺激症状;此外,术中合理应用丝裂霉素,可有效抑制术后haze的形成.

abstractsExcimer laser corneal refractive surgeries for refractive error corrections can be divided in two categories:intrastromal ablations (LASIK,FS-LASIK,SMILE) and surface (sub-epithelial) ablations (PRK,LASEK,Epi-LASIK,TPRK).Even though intrastromal ablations are also in the mainstream,surface ablations will become more popular due to surgical safety and intact corneal biomechanics without any flap complications.The most problems causing concern are post-operative pain and haze that can be minimized with topical non-steroid anti-inflammation drugs and mitomycin C,respectively.
