【摘要】：目的：观察硬性透气性角膜接触镜(rigid gas permeable contact lens, RGPCL)用于外伤后无晶状体眼视功能重建的可行性、有效性和安全性。方法：对17例(16男1女)单眼眼外伤后无晶状体眼做回顾性研究。17例患者均单眼佩戴RGPCL,其中包括9例虹膜缺失患者佩戴棕色镜片,并记录其裸眼视力(uncorrected visual acuity, UCVA),最佳框架眼镜矫正视力(best spectacle corrected visual acuity, BSCVA)及最佳角膜接触镜矫正视力(best contact lens corrected visual acuity, BCLCVA)。结果：17例单眼外伤无晶状体眼患者佩戴RGPCL,其中8片为无色镜片,9片为棕色镜片。用框架眼镜矫正,最佳矫正视力(best corrected visual acuity, BCVA)"g0.3有7眼(41.2%),BCVA≥0.5有4眼(23.5%)；RGP角膜接触镜矫正,BCVA"g0.3有15眼(88.2%),BCVA≥0.5有10眼(58.8%)。每天佩戴RGPCL8小时以上16例(94.1%),1例选择Ⅱ期后房型人工晶体植入术。7例(41.2%)出现角膜点状着色,4例(23.5%)发生巨乳头状结膜炎,2例(11.8%)戴镜前角膜有新生血管,随访结束时新生血管未见明显变化,无角膜水肿或感染情况发生。1例在随访过程中镜片破碎,之后补配同样规格镜片,其余镜片均完整。结论：硬性透气性角膜接触镜在单眼外伤后无晶状体引起的屈光异常治疗中是一种有效的方法,具有较高的安全性,良好的耐受性,并且可以矫正角膜疤痕引起的不规则散光。棕色镜片可以改善虹膜缺失造成的畏光,同时起到美容的效果。
[Abstract]:Objective: to observe the feasibility of rigid gas permeable contact Lens (RGPCL) in the reconstruction of visual function of aphakic eyes after trauma. Methods: a retrospective study was conducted on 17 patients with single eye trauma, including 17 patients with iris deficiency, who were treated with RGPCL, and 9 patients with iris deficiency, who were treated with RGPCL.Methods: a retrospective study was conducted in 17 patients with monocular trauma, including 9 patients with iris deficiency, who wore brown lenses. The best spectacle corrected visual acuities (BSCVAs) and best contact lens corrected visual acuities (BCLCVA) of best spectacle corrected visual were recorded. Results 17 patients with monocular trauma were given RGPCLs, 8 of them were RGPCLs. Colorless lenses 9 brown lenses. Corrected with frame glasses, Best corrected visual acuity (BCVA) "G0.3 has 7 eyes (41.2%) with BCVA 鈮，
