【摘要】 本研究对20只青紫蓝兔32只眼行 Nd:YAG 激光虹膜切开术,用扫描电镜观察术后1~4小时内至8个月的角膜内皮损伤及修复过程。结果表明,Nd:YAG 激光虹膜切开,可导致轻重程度不同的角膜内皮损伤,这种损伤在术后8个月内借助周围内皮细胞的移行及增殖,逐渐得以修复。

【Abstract】 Nd:YAG laser iridotomy was performed on 32 eyes of 20 Chinchilla rabbits and fol- lowed-up for 1-4 hours postoperatively to 8 months.Scanning electron microscopy show- ed that the corneal endothelium was dam- aged to various degrees by Nd:YAG laser iridotomy and the impaired areas healed up in 8 months through migration and prolifer- ation of the endothelial eclls.
