Eye care practitioners (ECPs) acknowledge that their patients do not always follow recommendations for lens replacement, but many may not realize the possible implications for their offices. The study was conducted to investigate whether there is a relationship between contact lens compliance and the interval between full eye examinations (IEE).
The study was conducted in ECP offices in the United States. Eye care practitioners and patients independently completed linked questionnaires, evaluating their contact lens wear and care. Patients were required to be current wearers of daily disposable (DD) lenses or reusable silicone hydrogel lenses with a manufacturer-recommended replacement frequency (MRRF) of 2 weeks (2WR) or 1 month (1MR).
A total of 2147 questionnaires from 141 offices were eligible. Fifty-four percent of patients were wearing 2WR, 37% 1MR, and 9% DD lenses. Wearers of 2WR lenses were significantly less compliant with replacement than wearers of both DD and 1MR lenses (34% vs. 74% and 67%, both p < 0.001); patients purchasing an annual supply were more compliant (55% vs. 45%, p < 0.001). The mean IEE was 16 months and was longer for wearers who were noncompliant with the MRRF (17.4 months vs. 14.5 months, p < 0.001). Other factors affecting IEE were household income (p = 0.030), insurance (p < 0.001), purchase source (p < 0.001), and sex (p = 0.007).
Patients who were not compliant with the MRRF had longer IEEs and were less likely to purchase an annual supply of lenses. Patients who purchased lenses from their ECP, had a higher household income, had eye examination insurance, and were female had shorter IEEs. Patients failing to replace their lenses when scheduled were also found to be less compliant with lens care procedures. Eye care practitioners should reinforce the importance of all aspects of lens wear and care with their patients, with the overall aim of reducing possible complications and retaining successful contact lens wearers in their offices.
眼科护理从业者（ECP）承认他们的患者并不总是遵循镜片更换建议，但许多人可能没有意识到这对他们诊所的潜在影响。本研究旨在调查隐形眼镜佩戴依从性与全眼部检查间隔时间（IEE）之间是否存在关联。
该研究在美国的眼科护理从业者诊所进行。眼科护理从业者和患者分别独立完成相关问卷，评估他们的隐形眼镜佩戴和护理情况。患者需为当前佩戴日抛型（DD）镜片或可重复使用的硅水凝胶镜片的人群，制造商建议的更换频率（MRRF）为每2周（2WR）或每月（1MR）。
来自141家诊所的总共2147份问卷符合要求。54%的患者佩戴每2周更换的镜片，37%佩戴每月更换的镜片，9%佩戴日抛型镜片。每2周更换镜片的佩戴者在更换方面的依从性明显低于日抛型和每月更换镜片的佩戴者（34%对74%和67%，p均<0.001）；购买年度供应量镜片的患者依从性更高（55%对45%，p<0.001）。平均全眼部检查间隔时间为16个月，未遵循制造商建议更换频率的佩戴者的间隔时间更长（17.4个月对14.5个月；p<0.001）。影响全眼部检查间隔时间的其他因素包括家庭收入（p = 0.030）、保险（p<0.001）、购买来源（p<0.001）和性别（p = 0.007）。
未遵循制造商建议更换频率的患者全眼部检查间隔时间更长，且购买年度供应量镜片的可能性更小。从其眼科护理从业者处购买镜片、家庭收入较高、拥有眼部检查保险以及为女性的患者全眼部检查间隔时间较短。还发现未按时更换镜片的患者在镜片护理程序方面的依从性也较低。眼科护理从业者应向患者强化镜片佩戴和护理各方面的重要性，总体目标是减少可能的并发症并使成功的隐形眼镜佩戴者继续留在他们的诊所。
