Independent OIE framework

From Functional Vision to Patient Outcomes

The framework integrates international consensus-based functional IOL classification with patient-centred clinical outcomes and the interpretation of evidence certainty.

01

Functional Classification

Measured visual range and defocus-curve characteristics

02

Patient-Centred Outcomes

Visual quality, spectacle independence and patient experience

03

Evidence Certainty

Reliability and clinical applicability of the available evidence

Evidence-informed IOL selection

An independent OIE evidence-interpretation framework, not a validated scoring system. No professional society or manufacturer endorsement is implied.
