PURPOSE
To present two cases with complications after Nd:YAG laser treatment of epithelial ingrowth.
METHODS
Case reports.
RESULTS
Dense central recurrent epithelial ingrowth was treated with a Nd:YAG laser directed at the epithelial nests in the LASIK flap interface in one case. Misalignment of the aiming beam after movement resulted in perforation of the LASIK flap, followed by renewed epithelial ingrowth through the new defect. The epithelial ingrowth receded and became more translucent as a result of the treatment, but the area of the perforation remained irregular. In another case, use of the Nd:YAG laser to treat recurrent epithelial ingrowth adjacent to the flap edge created a cavitation bubble that broke through the flap edge, creating a new epithelial channel through which ingrowth recurred.
CONCLUSIONS
Surface breakthrough and renewed epithelial ingrowth is a possible complication of Nd:YAG laser treatment of epithelial ingrowth.
目的
介绍两例Nd:YAG激光治疗上皮内生后出现并发症的病例。
方法
病例报告。
结果
一例中，对LASIK瓣界面处上皮巢的密集中央复发性上皮内生采用Nd:YAG激光治疗。移动后瞄准光束未对准导致LASIK瓣穿孔，随后上皮通过新的缺损再次内生。治疗后上皮内生消退并变得更透明，但穿孔区域仍不规则。另一例中，使用Nd:YAG激光治疗瓣边缘附近的复发性上皮内生时产生了一个空化气泡，该气泡穿透瓣边缘，形成了一个新的上皮通道，上皮通过该通道再次内生。
结论
表面突破和上皮再次内生是Nd:YAG激光治疗上皮内生可能出现的并发症。
