Content development for a new item-bank for measuring multifocal contact lens performance. J Patient Rep Outcomes. 2024 Feb 8;8(1):16. doi: 10.1186/s41687-024-00689-w. PMID: 38329635; PMCID: PMC10853121.2509-802010.1186/s41687-024-00689-whttps://hdl.handle.net/20.500.14352/101854Received: 04 July 2023; Accepted: 18 January 2024; Published: 08 February 2024;Background: Presbyopia is an age-related condition that causes a decreased ability to focus on nearby objects. Multifocal contact lenses are commonly used to address this issue. However, there seems to be a notable dissatisfaction among multifocal contact lens wearers. The absence of a reliable instrument to measure the patient's perspective, despite the widespread use of this method, highlights the need for further research in this area. Objective: The objective of this study is to develop an item-bank integrating all domains necessary to assess the patient's perspective on multifocal contact lens performance, offering a comprehensive measure. The item-bank will ensure a high level of content validity, be self-administered, and will initially be available in Spanish. The aim of this tool is to serve as a valuable resource for research and optometric clinics, facilitating the follow-up of patients with presbyopia who wear multifocal contact lenses or those who are newly starting to use them. Methodology: The MCL-PRO item bank, followed a systematic and step-wise inductive approach to gather information, following the recommendations outlined in the COSMIN guidelines and similar studies. The process involved the following steps: (1) Literature review and relevant existing items identification (2) Social media review, (3) Semi-structured focus groups, (4) performing qualitative analysis, (5) refining and revising the items, and (6) generating the content of the item bank. Results: A total of 575 items were included in the item-bank hosted under 8 different domains that were found to be important for presbyopic population: visual symptoms (213), activity limitation (111), ocular symptoms (135), convenience (36), emotional well-being (33), general symptoms (16), cognitive issues (21) and economic issues (10). Conclusion: The item-bank created has followed standardised methodology for its development and encloses all the aspects for MCL performance evaluation from patients perspective.engAttribution-ShareAlike 4.0 Internationaljournal article2509-8020https://doi.org/10.1186/s41687-024-00689-w38329635https://jpro.springeropen.com/articles/10.1186/s41687-024-00689-wopen access617.7-089.243681.73Content-validityItem bankPatient-reported outcomePresbyopiaQualitative researchÓptica y optometríaLentes de contacto2209.15 Optometría3311.09 Lentes
