Matrix Acrylic IOL - A New Peak in Acrylic Lens Technology
Matrix Acrylic is the newest technology available in acrylic lens design. This unique foldable, hydrophobic lens combines exceptional material and design properties to achieve truly innovative results.

Biostability
• Unique foldable hydrophobic acrylic material
• Single monomer formulation developed to be biostable
• High index of refraction

Biomechanics
• Highest tensile strength designed to resist optic damage during folding and insertion
• Polyvinylidene (PVDF) haptics chosen for their superior memory and compressibility, designed to ensure complete shape recovery

Diameter: 6.0 mm optic Haptic: PVDF – Modified C
Material: Hydrophobic acrylic A Constant: 118.5
Range: 0.0 to 30.0 Diopters Refractive Index (@25 C): 1.56

Proven Design Properties

Optic
Symmetric biconvex optic designed to:
• Minimize cosmetically undesirable external reflection in the pupil2
• Minimize internally reflected glare2
• Provide consistent lens geometry across all diopters, maximizing refractive predictability

Full optic design
• No redundant outer ring to reduce effective optic zone
• Fully functional 6 mm optic

Sharp edge designed to:
• Reduce potential for lens epithelial cell migration onto posterior capsule

Haptics
• Polyvinylidene (PVDF) haptics to eliminate capsule folds and enhance stability
• 5 ° angulation designed to provide early and effective optic/capsule contact thereby minimizing migration of lens epithelial cells to the posterior capsule3

Matrix Acrylic — offering all the advantages of other hydrophobic acrylic lenses, with none of the compromises.

A clinical study of Matrix Acrylic is currently underway in the U.S.A.
