Advanced Optical Engineering

Ultra Definition

Advanced Vision of Aspheric Design

Ultra Definition optic design corrects spherical aberrations coming from both cornea and IOL. However, AcrivaUD IOLs have a slight negative asphericity, which maintains part of the positive aberration of the cornea, helping patient to keep better depth of focus.

Advantage of Ultra Definition Design

  • Improved contrast sensitivity under low light condition
  • Preserved depth of focus
  • Less sensitive to decentration

Superior Chromatic Aberration Control

Abbe Number of AcrivaUD is 58, one of the highest numbers in the IOL market, measured by independent laboratory. Superior chromatic aberration control in all AcrivaUD lines.

The Importance of Abbe Number

Chromatic aberration is type of distortion in optical system formed by different wavelengths of light to have different focal points. The higher the Abbe number is the lower the chromatic dispersion is.

High MTF Values

Better Visual Quality

The MTF of all AcrivaUD lenses is checked one by one and value is always above international standards limits. AcrivaUD products demonstrates superior MTF and smooth surface topography, thanks to our innovative optic engineering.

Modular Transfer Function

MTF is a direct and quantitative measurement of optic system quality. The best result through obstacles is 0.7 at 100 lpm. According to international standards the MTF result at an IOL must be above 0.43 at 100 lpm3. VSY Biotechnology has determined its own quality control limits far stricter than international standards.

Wide Diopter Range

Complete Solution

AcrivaUD has a full range of diopters from -20.00D to +45.00D, in 0.50D increments. Special production is from -20.00D to 0.0D and from +32.00D to +45.00D in 0.50D increments.

Premium Material

Best of Both Worlds!

Excellent material combination of 2-Oxiethylmethacrylate and 2-Hydroxymethacrylate monomers create hydrophobic surface behavior with the advantage of hydrophilic flexibility.

Proven Hydrophobic Surface Behavior

AcrivaUD TrinovaTM has similar contact angle measurements similar to pure hydrophobic IOLs. An independent comparative study showed that the hydrophobic surface of AcrivaUD TrinovaTM is similar to that of pure hydrophobic competitors.

Benefits of Hydrophobic and Hydrophilic Monomers

  • No glistening
  • No calcification
  • Low inflammatory response
  • Limited PCO
  • Easy to fold and inject
  • Quickly unfolding in the eye
  • High biocompatibility
  • MICS capability

Better Flexibility

The elastic co-polymer of AcrivaUD TrinovaTM has precise memory. Point Spread Function (PSF) shows that the optic quickly recovers its initial shape within one hour, much quicker than hydrophobic IOLs.

Optimum Filtration Range – Balanced Photoprotection of UVA and Violet Spectrum

AcrivaUD BB provides excellent photoprotection from potential damage of the UVA and violet spectrum without blocking blue light. AcrivaUD BB ensures 95% blue light transmission at 480 nm which is known as critical in controlling the circadian rhythm

The chromophore used in AcrivaUD BB material is the same chromophore as in the human natural lens which gives similar transmission structure as a young human lens.

Importance of Blue Light

Blue light plays a crucial role in controlling the circadian rhythm and endogenous melatonin secretion. Disorganisation of the circadian rhythm is more common in older adults and people with insomnia, depression and dementia. Blue-blocking IOLs which contain synthetic dye filter up to 500 nm causes excessive filtering of blue light.

Natural Chromophore – Same Transmission Properties than Natural Lens

AcrivaUD BB contains 3-hydroxykynurenine which is exactly the same as in our natural lens. Chromophore structure of AcrivaUD possesses the same transmission as a human natural crystalline lens with a good protection of the macula against UV-A and blue light thanks to the absorption curve which mimics the human crystalline lens, preserving the natural color perception and contrast sensitivity.

Ideal Concentration – Improved Contrast Sensitivity

AcrivaUD BB’s chromophore concentration is 0.02%. It has a clearer color in comparison to IOLs with higher concentrations of chromophores. Low concentration of AcrivaUD BB does not influence color perception of the patient. Natural chromophore and its lower concentration provide a higher contrast sensitivity under low light condition.

Biomechanics

360⁰ All Square Enhanced Edge

PCO Barrier 
The innovative edge design tends to greatly reduce PCO risk by forming a geometric and mechanical barrier against cells proliferation. The edge design produces thinner lenses for equivalent power than competitors.

Exceptional Design 
360° All Enhanced Square Edge and premium material form a dual barrier against the risk of posterior capsule opacification after implantation. Recent studies have shown that square edge on posterior surface of the optic is the most important IOL-related factor against PCO
