Construction of multi-dimensional value evaluation index system of intraocular lens / 医疗卫生装备

ABSTRACT

Objective To develop two multi-dimensional value evaluation index systems for intraocular lens(IOL)to assist decision makers in selecting appropriate IOLs.Methods IOL value assessment indexes were determined preliminarily through literature research and expert consultation,and the weights of the indexes were calculated through hierarchical analysis method and then ranked to form two evaluation index systems.Results Two multi-dimensional value evaluation index systems were constructed for monofocal and refractive IOLs respectively,which both contained 3 first-level indicators and 13 second-level indicators;the evaluation index system for monofocal IOL involved in 26 third-level indicators,and the other for refractive IOL had 33 third-level indicators.The three first-level indicators of the two systems were ranked by weight as clinical dimension,economic dimension and institutional dimension.The monofocal IOL evaluation index system had product performance being the second-level indicator with the highest weight,and the top three third-level indicators with the highest weights being lens capsule biocompatibility,risk of intraocular lens damage during implantation and range of applicable populations;the refractive IOL evaluation index system had clinical efficacy(vision)being the second-level indicator with the highest weight,and the top three third-level indicators with the highest weights being distant vision,(astigmatism)rotational stability/postoperative axial rotation and near vision.Conclusion The multi-dimensional value evaluation index systems developed provide references for comprehensive value evaluation of IOLs.[Chinese Medical Equipment Journal,2023,44(11):83-89]
