Enhanced Depth of Focus Concept in Reviol Tri-ED Optic 1. Active Diffractive Optic 2. Semi-Apodization 3. True TriFocality
Enhanced Depth of Focus Concept The Reliable performance of Reviol Active-Diffractive IOL has been proven in over forty countries with thousand implantations Active Diffractive Optic Characteristic of Active Diffractive Optic Maximum Light Energy Transmission
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 14.3% in Zeiss 15.0% in Physiol
Enhanced Depth of Focus Concept Semi-Apodized Trifocal Optic Benefits of Semi-Apodization Optimal Light Distribution
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

Enhanced Depth of Focus Concept True Trifocality 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. Opthalmic Optic General Information III Focal overlapping between light centralization in different points plays a negative role in image quality and photopic phenomena (glare/halo) problems*. *Petermeier K., Messias A., Gekeler F., Szurman P.

First Clinical Findings Post-op Refraction Spherical Equivalent - 0.18 ± 0.38
First Clinical Findings Visual Acuity UDVA (Uncorrected Far) -0.03 ± 0.07 UIVA (Uncorrected Intermediate) 0.16 ± 0.09 UVNA (Uncorrected Near) 0.06 ± 0.12 *LogMar Acuity
First Clinical Findings Defocus Curve Distinctive intermediate acuity
First Clinical Findings Good Contrast Sensitivity Results Contrast sensitivities are measured by CSV1000E, Vector Vision by glare and without glare. All eyes showed good results at 3, 6, 12 and 18 spatial frequency (cpd) Patient Satisfaction No moderate/severe glare halo problem reported. Over 95% of patients dont need glasses.
