目的 探讨少年儿童单眼外伤术后无晶状体眼的接触镜(CL)矫正方法和临床效果。方法 观察81名少年儿童眼外伤术后患者的眼部改变,并根据其屈光状态的变化、对侧眼的状态及其生活的实际需要,选择验配了软性接触镜(SCL)、托力克软性接触镜(TSCL)、透气性硬性接触镜(RGPCL)、加虹膜色彩的非透气性硬性接触镜(PMMA虹彩片)和软、硬组合型镜片系统(Piggyback CL),并比较视力矫正效果。结果 与对侧健眼比较,外伤术后眼角膜曲率半径值显著改变,角膜散光度明显增加。52眼选用SCL和TSCL,矫正视力与框架眼镜比较无明显差异;22眼选用RGPCL,4眼选用PMMA虹彩镜,3眼选用Piggyback CL,三种镜片矫正视力比框架眼镜明显提高。PMMA虹彩镜和Piggyback CL用于外伤后角膜白斑、术后无晶状体、虹膜严重损伤眼,除显著提高视力外,还明显改善了羞明症状和眼外观。结论 在严格的医疗化管理下,利用CL矫正少儿眼外伤术后无晶状体眼的高度屈光不正、屈光参差,恢复双眼视觉是安全、有效的。硬性接触镜(HCL)的视力矫正效果明显优于SCL。
Objective To investigate the method and clinical effect of contact lens (CL) correction in children with aphakia after monocular injury. Methods Eighty - one eyes of 81 children with ocular trauma were observed for ophthalmic changes. According to the change of refractive status, the status of the lateral eye and the actual needs of their life, 81 patients were examined with soft contact lens (SCL) Lectra soft contact lens (TSCL), rigid contact lens (RGPCL), iris-impermeable rigid contact lens (PMMA iridescent), and soft and hard combined lens system (Piggyback CL) effect. Results Compared with contralateral healthy eyes, corneal curvature radius significantly changed after trauma, and corneal astigmatism increased significantly. There were no significant differences between 52 eyes using SCL and TSCL, 22 eyes with RGPCL, 4 eyes with PMMA iridescence and 3 eyes with Piggyback CL. The visual acuity of the three lenses was significantly higher than that of the glasses. PMMA iridescent and Piggyback CL are used for post-traumatic corneal leukoplakia. After surgery, aphakia and iris severely damage the eyes. In addition to significantly improving visual acuity, they also significantly improve shame symptoms and eye appearance. Conclusions Under the strict medical management, it is safe and effective to correct the high ametropia, anisometropia and binocular vision of aphakia after CL correction of children ocular trauma. Hard contact lenses (HCL) visual acuity was significantly better than SCL.
