Introduction

Active Diffractive Optic Seamless Continuous Vision Balanced Near/Intermediate Addition Pupil-Independent Premium Material Photo protection

Full Diffractive Trifocal Optic Enhanced by Depth of Focus Vision*

* Patent Pending New Design

New! True Trifocal optic having superior MTF results at intermediate zones

Enhanced Depth of Focus Concept in Reviol Tri-ED Optic

• 1. Active Diffractive Optic
• 2. Semi-Apodization
• 3. True TriFocality

Active Diffractive Optic

Characteristic of Active Diffractive Optic Maximum Light Energy Transmission The Reliable performance of Reviol Active-Diffractive IOL has been proven in

• ver forty countries with thousand implantations

Enhanced Depth of Focus Concept

Active Diffractive Reviol Tri-ED

Maximum Light Transmission Effective light transmission reach up 89.1%, It means light loss is 10.9% which is minimum value in the trifocal IOL market . Light Loss in Competitors

15.0% in Physiol 14.3% in Zeiss

Semi-Apodized Trifocal Optic

Benefits of Semi-Apodization Optimal Light Distribution

Enhanced Depth of Focus Concept

Semi-Apodization

Optimal Light Distribution Light is distributed through the focal area with excellent balance. Reviol Tri-ED light splitting structure of transmitted light in 6 mm aperture:

44% for Far 28% for Intermediate 28% for Near

True Trifocality

Enhanced Depth of Focus Concept

True trifocal? Appropriate Disparity between focus

True Trifocality

Appropriate Disparity Reviol Tri-ED is combined with 3.0D Near Addition and 1.5D Intermediate Addition. Focal overlapping between light centralization in different points plays a negative role in image quality and photopic phenomena (glare/halo) problems*.
