PURPOSE:To determine the retention rate (RR) for neophyte patients fitted with contact lenses (CLs) and to identify factors associated with retention and dropout. METHOD:This multisite, sponsor-masked registry study evaluated the 1-year status of neophyte CL wearers fitted in a representative range of UK practices. A total of 26 UK investigational sites each recruited up to 89 neophyte patients. The participants were requested to complete surveys at 1 month (±1 week from date of fitting), 3 months (±2 weeks), and 12 months (±3 weeks) online or through phone. Participants were contacted by email (or phone) and invited to complete an online survey that asked a range of questions regarding their CL wearing experience. RESULTS:Of the 531 participants recruited, 65.3% (347/531) responded to at least one follow-up survey and 42.3% (225/531) responded to all three surveys. One in four patients showed discontinued CL wear by 12 months. Based on evaluable subjects at 12 months, the RR was 77.6% (194/250, 95% confidence interval: 72.0-82.3). The most common reason for discontinuation was problems with vision (41%), followed by discomfort (36%) and handling problems (25%). The factors affecting first-year RRs: sex, spherical refraction, lens usage (full time or part time), and supply method (collected or posted). CONCLUSIONS:In this prospective study, the first-year RR for neophyte CL wearers was 77.6%. This was consistent with that noted in a retrospective study: 74.0%. As with the previous study, the commonly cited reason for discontinuation was visual problems.

目的:确定配戴隐形眼镜(CL)的初生患者的保留率(RR),并确定与保留和辍学相关的因素。
方法:这项由赞助商掩盖的多站点注册表研究评估了英国代表性实践中安装的初生CL佩戴者的1年状态。总共有26个英国研究场所各自招募了89名新生患者。要求参与者在1个月(自安装之日起±1周),3个月(±2周)和12个月(±3周)内通过在线或电话完成调查。通过电子邮件(或电话)与参与者进行了联系,并邀请他们完成在线调查,询问有关其穿着CL的经历的一系列问题。
结果:在招募的531名参与者中,有65.3%(347/531)回答了至少一项随访调查,而42.3%(225/531)回答了全部三项调查。四分之一的患者显示12个月后不再佩戴CL。根据在12个月时可评估的受试者,RR为77.6%(194 / 250,95%置信区间:72.0-82.3)。停药的最常见原因是视力问题(41%),其次是不适感(36%)和操作问题(25%)。影响第一年RR的因素:性别,球面屈光度,镜片使用情况(全职或兼职)和供应方式(收集或发布)。
结论:在这项前瞻性研究中,初生CL佩戴者的第一年RR为77.6%。这与回顾性研究中指出的一致:74.0%。与先前的研究一样,停药的原因通常是视觉问题。
