OBJECTIVE
The study was designed to approach the operative techniques of penetrating keratoplasty (PKP) in children and the influential factors on the rate of graft clarity.
METHODS
PKP was performed on 33 eyes of 30 children whose corneal opacities resulted from various causes and they were followed for 6 months to 3 years.
RESULTS
The rate of graft clarity was 66.7% and 44.8% of these eyes were relieved from blindness. The poorest results achieved were in cases with congenital corneal opacity and the main cause of graft failure is endothelial immune rejection.
CONCLUSION
Although the surgical results in children are poorer than that in adults, from the concern of prevention of amblyopia and cosmetic problem, it is necessary to perform the operation earlier.
目的
本研究旨在探讨儿童穿透性角膜移植术（PKP）的手术技巧以及影响植片透明率的因素。
方法
对30例因各种原因导致角膜混浊的儿童的33只眼进行了穿透性角膜移植术，并对其进行了6个月至3年的随访。
结果
植片透明率为66.7%，其中44.8%的患眼视力得到改善。先天性角膜混浊病例的手术效果最差，植片失败的主要原因是内皮免疫排斥反应。
结论
虽然儿童的手术效果比成人差，但从预防弱视和美容问题的角度考虑，有必要尽早进行手术。
