夜戴型角膜塑形镜对近视患者睡眠质量的影响

目的：观察配戴夜戴型角膜塑形镜对近视患者睡眠质量的影响。

方法：选取就诊于福建中医药大学附属人民医院眼科配戴夜戴型角膜塑形镜的近视患者30例58眼为试验组，随机选取同期配戴框架眼镜的近视患者30例60眼作为对照组。所有患者分别于戴镜前和戴镜后1、3mo应用匹茨堡睡眠质量指数量表(Pittsburgh Sleep Quality Index，PSQI)进行睡眠质量评估， 观察比较两组患者的睡眠质量。

结果：试验组患者戴镜前、戴镜后1、3mo等效球镜度数分别为-2.78±0.90、-0.30±0.31、-0.28±0.30D，戴镜后1、3mo分别与戴镜前比较，差异均有统计学意义(P<0.05)。戴镜前、戴镜后1、3mo试验组PSQI评分分别是2.13±1.36、2.47±1.98、1.74±1.39分。试验组与对照组比较，戴镜后3mo主观睡眠质量评分的差异具有统计学意义(P<0.05)，而PSQI评分和入睡时间、睡眠时间、睡眠效率、睡眠障碍、催眠药物、日间功能的评分差异均无统计学意义(P>0.05)。

结论：配戴夜戴型角膜塑形镜对近视患者总体睡眠质量无明显影响，在配戴初期患者主观睡眠质量下降。

Influence of nocturnal orthokeratology lens on sleep quality in myopic patients

AIM:To observe the influence of wearing nocturnal orthokeratology lens on sleep quality in myopic patients.

METHODS:Totally 30 myopic patients(58 eyes)wearing nocturnal orthokeratology lens, who received medical treatment at the Department of Ophthalmology of Affiliated People''s Hospital of Fujian University of Traditional Chinese Medicine, were included in study(treated group). And 30 myopic patients wearing spectacles at the same time were randomly selected as the control group. Sleep quality of two groups were assessed with Pittsburgh sleep quality index(PSQI)before and after wearing the lens in the first and the third months, and compared.

RESULTS: Equivalent diopter of the 30 patients wearing nocturnal orthokeratology lens was -2.78D±0.90D before treated with orthokeratology lens, -0.30D±0.31D after 1mo of treatment, and -0.28D±0.30D after 3mo of treatment. There was significant difference between the equivalent diopter got before treated with orthokeratology lens and that got after 1mo of treatment(P<0.05), and between the equivalent diopter got before treated with orthokeratology lens and that got after 3mo of treatment(P<0.05). The total scores of PSQI of 30 myopic patients got before wearing nocturnal orthokeratology lens and after 1 or 3mo of that were respectively 2.13±1.36, 2.47±1.98, and 1.74±1.39. There only was significant difference in scores of subjective sleep quality got after 3mo of treatment between treated group and control group(P<0.05), but no significant difference in scores of total PSQI, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction(P>0.05).

CONCLUSION: Wearing nocturnal orthokeratology lens has no significant effect on the overall sleep quality index of myopic patients, but the subjective sleep quality decreased in the early stage of wearing the lens.
