目的: 通过观察配戴高透氧性硬性角膜接触镜(rigid gas permeable contact lens ,RGP)的并发症,探讨RGP并发症的处理及预防。
方法: 配戴RGP患者54例101眼,分别记录配戴前后视力、屈光度、裂隙灯及角膜地形图结果,随访观察12mo,研究分析并发症发生情况及相应处理的有效性。
结果:本组患者在配戴过程中发生的并发症主要有干涩不适16眼(15.8%); 异物感8眼(7.9%); 角膜上皮点状脱落7眼(6.9%); 结膜过敏性炎症3眼(3.0%); 角膜外伤1眼(1.0%); 眼镜护理不当15眼(14.9%),包括镜片污浊划痕10眼,镜片丢失3眼,镜片碎裂2眼。除有2例因眼部不适停戴外其他患者经对症处理均能满意接受配戴。
结论:详细的试戴前检查、正规验配过程及严格随诊可以有效预防并减少RGP并发症的发生。

AIM: To assess the complications induced by wearing rigid gas permeable contact lens(RGP), and to discuss the preventions and treatments of theses complications.
METHODS: Totally 54 patients 101 eyes who underwent RGP therapy were observed alone for 1 year. The patients complains were recorded, routine eye examinations were conducted(including vision, refraction, ocular pressure, slit-lamp findings and corneal topography), the abnormal findings and the treatments were analyzed.
