目的 探讨OK镜治疗中对角膜上皮的损害及其影响因素。 方法 总结分析随访 4周的OK镜治疗患者 1 0 6例 ( 2 1 0眼 )。结果 本组出现角膜上皮染色 68例 1 36眼占 64 8% (其中Ⅰ级4 4 1 % ,Ⅱ级 35 3% ,Ⅲ级 1 7 6% ,Ⅳ级 2 9% )。角膜上皮染色检出率在镜片配适过紧组高于配适正常组 ,在治疗前泪膜破裂时间 <1 5s组高于≥ 1 5s组 ,差异有显著性 ;而角膜染色与镜片中心定位间无明显统计学差异。结论 角膜上皮损伤与OK镜过紧配戴及治疗前泪膜破裂时间有关。建议对OK镜治疗者应注意长期随访 ,重视角膜上皮健康
Objective To investigate the damage of corneal epithelium and its influencing factors in the treatment of OK. Methods A total of 106 patients (210 eyes) treated with OK lens were followed up for 4 weeks. Results 68 cases of corneal epithelial staining in this group accounted for 648% of the total of 36 eyes (441% of grade Ⅰ, 35% of grade Ⅱ, 176% of grade Ⅲ and 29% of grade Ⅳ). The detection rate of corneal epithelial staining in the lens overfit group was higher than that in the normal group. Before the treatment, the tear film rupture time was higher than that in the <15s group (> 15s), and the difference was significant. However, corneal staining and lens center location No significant statistical difference between. Conclusions Corneal epithelial injury is associated with tight wear of OK lens and rupture of tear film before treatment. It is recommended that OK mirror treatment should pay attention to long-term follow-up, attention to corneal epithelial health
