夜戴型角膜塑形镜治疗青少年轻中度近视的临床疗效评估

Clinical evaluation of rigid gas permeable over night orthokeratology lens effect on mild and middle myopia for teenager

目的通过观察高透氧性夜戴型硬性角膜塑形镜片的临床应用情况,评价角膜塑形镜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7~15岁轻中度近视眼患者35例(70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3个月,观察其疗效、并发症及配戴者主观症状。结果裸眼视力:配戴前与配戴后7 d、1 mo及3 mo差异具有统计学意义(均P<0.05)。等效球镜:配戴前与配戴后7 d、1 mo及3 mo差异具有统计学意义(均P<0.05)。角膜厚度与眼压各时间段两两比较均无统计学差异。各时间段角膜损伤中以轻度损伤所占比例最大。OV 100%:配戴后7 d与配戴后1 mo及3 mo有显著差异(均P<0.05),其余时间点无差异;OV 20%:配戴前与配戴后1 mo、3 mo,配戴后1 mo与3 mo,配戴后7 d与1 mo及3 mo差异具有统计学意义(均P<0.05);OV 9%:7 d与配戴后1 mo、3 mo,配戴前与配戴后1 mo、3 mo差异有统计学意义(均P<0.05),其余时间点无差异。结论高透氧性角膜塑形镜矫治青少年轻中度近视是安全的、有效的,但会影响视觉质量。

Objective To observe the clinical effects of rigid gas permeable contact lens , evaluate the safety and effect of orthokeratology , and analyze relevant factors for teenagers .Methods Thirty-five patients (70 eyes, aging from 7 to 15 years old) were followed up for three months .All patients wore night orthokeratology lens after standard optometry for spectacles .The therapeutic effect complications , subjective feeling were observed . Results There was statistical difference between before treatment and 7d, 1mo, 3mo in UCVA group ( P <0.05).There was statistical difference between before treatment and 7d, 1mo, 3mo in SE group(P<0.05). There was not statistical difference in the corneal thickness group and intraocular pressure group .The proportion of mild injury was the largest in corneal damage .There was statistical difference between 7d and 1mo,3mo in OV100%group(P<0.05).There was statistical difference between before treatment and 1mo, 3mo, 1mo and 3mo, 7d and 1mo, 3mo in OV20% group(P<0.05).There was statistical difference between 7d and 1mo, 3mo, before treatment and 1mo, 3mo in OV9% group(P<0.05).Conclusions Orthokeratology lens are safe and effective for treating mild and middle myopia of teenagers , but it can impact visual quality .
