Simultaneous Vision IOLs ESCRS Classification (Pre-recorded)

Joaquín FERNÁNDEZSpain Speaker Simultaneous Vision IOLs ESCRS ClassificationThe rapid expansion of intraocular lens (IOL) designs and the increasing volume of clinical research supporting their functional outcomes have underscored the need for a unified and globally standardized Functional Vision Framework. The European, American, Asia-Pacific, and Latin American Societies of Cataract and Refractive Surgeons have collaboratively established the Global Functional Vision Working Group (FVWG) to harmonize terminology, methodologies, and outcome reporting in IOL evaluation. This initiative introduces a Functional Classification based on the depth of field (DOFi) and visual acuity enhancement across intermediate to near distances, organized into six progressive categories reflecting different visual performance profiles. Unlike regulatory classifications, such as ISO 11979-7:2024, which focus on safety and pre-market efficacy, the FVWG Functional Classification aims to provide post-market, clinically meaningful differentiation that aligns with patient-centered care and real-world functional benefits. The framework also advocates the integration of additional endpoints, including contrast sensitivity, biometric influences, and validated patient-reported outcome measures such as the AIOLIS questionnaire. Future directions emphasize the development of guidelines to assess the certainty of functional performance based on a hierarchy of evidence, from optical bench predictions to clinical validation and meta-analyses. By aligning technical and patient-oriented perspectives, the FVWG’s Functional Vision Framework represents a major advancement toward global standardization in IOL research and clinical practice. It provides clinicians, researchers, and industry with a robust foundation for consistent measurement, transparent communication, and improved shared decision-making in the selection and evaluation of IOL technologies.
