The purpose of this study was to evaluate the performance of verofilcon A daily disposable contact lenses (CL) in CL wearers who identified themselves as heavy digital device users.
This prospective, non-masked, open-label study enrolled CL wearers who reported ≥6 hours digital device use per day. Participants were dispensed with the verofilcon A study lenses for 14±2 days, to be worn for at least 5 days a week and 10 hours per day, while continuing their normal routine of digital device use. Participants rated the lens performance at the Day 14 visit using a 0-100 (with 100 being best) scale. Ratings were completed at lens insertion, after 6 hours of digital device use, just before CL removal and for overall experience. Participants also completed a 4-point (strongly agree/disagree, slightly agree/disagree) Likert scale-based questionnaire.
Thirty-two participants were eligible and completed the study (27 females; age 25.8 ± 6.0 years, ranging from 19 to 40). Overall lens performance ratings at the Day 14 visit (mean ± standard deviation) for comfort, dryness, and clarity of vision were 91 ± 11, 88 ± 11, and 92 ± 9, respectively. Subjective ratings were stable throughout the day with no significant differences after insertion, after 6 hours of digital device use and before CL removal (all p>0.05). The majority of participants agreed that the study lenses performed well, provided good all-day comfort (28/32; p<0.01) and good all-day vision (29/32; p<0.01). Participants also agreed that after ≥6 hours of digital device use they were satisfied with CL comfort (27/32; p<0.01), vision (29/32; p<0.01) and that the lenses provided good performance (26/32; p<0.01).
Verofilcon A lenses were found to perform well, with high ratings for comfort, dryness and vision that remained high throughout the day, during extensive digital device use.
本研究旨在评估每日更换型的维罗氏A隐形眼镜（CL）在自认为是重度数字设备使用者的隐形眼镜佩戴者中的表现。
这项前瞻性、非盲法、开放标签研究纳入了报告每天使用数字设备≥6小时的隐形眼镜佩戴者。参与者佩戴维罗氏A研究镜片14±2天，每周至少佩戴5天，每天佩戴10小时，同时继续其正常的数字设备使用习惯。参与者在第14次访视时使用0-100分制（100分为最佳）对镜片性能进行评分。评分在插入镜片时、使用数字设备6小时后、即将取下隐形眼镜前以及总体体验时完成。参与者还完成了一份基于4点（强烈同意/不同意、略有同意/不同意）李克特量表的问卷。
32名参与者符合条件并完成了研究（27名女性；年龄25.8±6.0岁，范围为19至40岁）。在第14次访视时，镜片在舒适度、干燥度和视力清晰度方面的总体性能评分（平均值±标准差）分别为91±11、88±11和92±9。主观评分在一天中保持稳定，在插入镜片后、使用数字设备6小时后和取下隐形眼镜前均无显著差异（所有p>0.05）。大多数参与者同意研究镜片表现良好，提供了良好的全天舒适度（28/32；p<0.01）和良好的全天视力（29/32；p<0.01）。参与者还同意，在使用数字设备≥6小时后，他们对隐形眼镜的舒适度（27/32；p<0.01）、视力（29/32；p<0.01）感到满意，并且镜片性能良好（26/32；p<0.01）。
研究发现，维罗氏A镜片表现良好，在长时间使用数字设备期间，其在舒适度、干燥度和视力方面的评分较高，且全天保持较高水平。
