Orthokeratology (OK) lens wear is an effective modality to inhibit axial elongation in myopic children. Willingness for commitment from both parents and children contributes to the success of OK treatment. We aimed to develop and assess the usability of a mobile application on OK lens wear by quantitatively and qualitatively evaluating parents with myopic children and eye care professionals (ECPs). Moreover, the preliminary outcome was also evaluated in this study. The app was developed and tested using a co-design approach involving key stakeholders. Two prototype tests were conducted during the feasibility and utility assessment. The app features include self-reported compliance documentation, analytics, and personalized and generalized messages for compliance behaviors of OK lenses. After the trial period, the full usage of app functions ranged from 40% to 60% among the enrolled parents. After app implementation, the compliance with follow-up visits substantially improved. Qualitative data show that the high-satisfaction app functions reported by parents were the app's reminder and axial length recording, although it was recommended that the number of compliance questions should be reduced to minimize the survey completion time. Additionally, who should complete the recording of the axial length data as well as the management and reminder for the follow-up visit remained controversial. This is the first app developed to improve parents of myopic children's compliance with OK lens wear and to assist ECPs and parents in collaboratively monitoring and managing the use and care of OK lenses among myopic children. This study highlights the importance of interdisciplinary collaboration in the design, development, and validation of such an app.
角膜塑形术（OK）镜片的佩戴是抑制近视儿童眼轴增长的有效手段。父母和孩子双方的配合意愿是 OK 治疗成功的关键。本研究旨在通过对近视儿童的家长和眼保健专业人员（ECP）进行定量和定性评估，开发和评估一种用于 OK 镜片佩戴的移动应用程序的可用性。此外，本研究还评估了初步结果。该应用程序采用了涉及关键利益相关者的共同设计方法进行开发和测试。在可行性和实用性评估期间进行了两次原型测试。该应用程序的功能包括自我报告的依从性文件、分析以及个性化和通用的 OK 镜片依从性行为消息。在试验期结束后，注册家长的应用程序功能的全使用率在 40%至 60%之间。在应用程序实施后，随访的依从性显著提高。定性数据显示，家长报告的满意度高的应用程序功能是应用程序的提醒和眼轴长度记录功能，尽管建议减少依从性问题的数量以尽量减少调查完成时间。此外，谁应该记录眼轴长度数据以及管理和提醒随访访问仍然存在争议。这是第一款旨在提高近视儿童家长对 OK 镜片佩戴依从性的应用程序，并帮助 ECP 和家长共同监测和管理近视儿童使用和护理 OK 镜片的应用程序。本研究强调了在设计、开发和验证此类应用程序时跨学科合作的重要性。
