“梦戴维”角膜塑形术矫治青少年轻中度近视的临床研究

Clinical studies of the effects of overnight orthokeratology lens on mild and middle myopia for teenager

目的:通过观察"梦戴维"高透氧夜戴型硬性角膜塑形镜片的临床应用情况,评价"梦戴维"角膜塑形术矫治青少年轻中度近视临床使用的安全性、有效性及其疗效,同时分析其相关因素。方法:选择我院眼科门诊的10～18岁轻中度近视眼儿童120例200眼,按照我院角膜塑形验配流程规范验配,均以夜戴镜片为主,随访6mo,观察其疗效、并发症及配戴者主观症状。结果:配戴6mo后配戴者主观症状基本良好;6mo后裸眼视力、屈光度、角膜地形图(K值)与配戴前比较差异统计上均有显著性(P<0.01),眼轴、矫正视力配戴前后比较差异统计学上无显著性(P>0.05)。结论:"梦戴维"角膜塑形术矫治青少年轻中度近视是安全的、有效的,但长期配戴必须严密观察及随诊,以确保长期治疗的安全性和有效性。

AIM： To observe the clinical effects of rigid gas permeable contact lens for orthokeratology, evaluate the safety and effectivity of orthokeratology for teenagers, and analyze relevant factors. METHODS： One hundred and twenty patients （200 eyes, aging from 10 to 18 years old） were followed up for six months. All patients wore night orthokeratology lens after standard optometry for spectacles. The therapeutic effect and complications, subjective feeling were observed. RESULTS： All patients after six months wearing felt favorable. Uncorrected visual acuity was improved after six months, the difference was significant （ P〈 0. 01 ）. Diopters and K value were lower than the past. The difference was significant （ P〈 0. 01 ）. There was no significant difference between the ocular axial length, corrected visuacacuity of before and after treatment. CONCLUSION： Orthokeratology lens are safe and effective for treating mild and middle myopia of teenager＇s. But the further study is needed to ensure the safety and effectivity for long wearing.
