OBJECTIVES: To reduce, score and assess the psychometric properties of the Freedom from Glasses Value Scale (FGVS), a new scale developed to measure benefits of freedom from glasses in cataract and presbyopic patients after multifocal intraocular lens (IOL) surgery. METHODS: The FGVS, a 21-item Patient-Reported Outcomes instrument, was developed simultaneously in French and Spanish. It was administered by phone in a study conducted with 152 French and 152 Spanish patients who underwent cataract or presbyopia surgery at least 1 year before the interview. Statistical methods (principal component analysis, multi-trait analysis) and content analysis were used to select the items and to score the FGVS. Psychometric properties (validation of the structure, internal consistency reliability, known-group validity) of the resulting version were assessed in the pooled population and by country. RESULTS: One item was removed from the FGVS, three motivation items were kept but not aggregated in a dimension, and two main dimensions were defined ('global evaluation', 9 items; 'advantages', 8 items). These two dimensions contain five subscores ('evaluation of the results', 2 items; 'feelings', 4 items; 'global judgment', 3 items; 'psychological advantages', 3 items; 'practical advantages', 5 items). A higher score indicates a higher benefit from surgery. The scores presented good psychometric properties; all items met the convergent validity criterion and only three did not meet the discriminant validity criterion. Cronbach’s alpha was greater than 0.70 for all dimensions and sub-dimensions (good internal consistency reliability), and the FGVS was able to discriminate between patients wearing glasses or not after surgery (higher scores for patients not wearing glasses). FGVS scores were significantly higher in Spain than in France, however, they showed similar psychometric performances in both countries. CONCLUSIONS:The FGVS is a valid and reliable instrument measuring benefits of freedom from glasses perceived by cataract and presbyopic patients after multifocal IOL surgery.
