IOL Acriva BB T UDM 611

All Features in One Design

 

1. Clinical Outcomes

 Minimum Residual Astigmatism

 AcrivaUD demonstrates outstanding performance with only 0.3D residual astigmatism in a clinical study performed with 26 patients. Also, there was no residual astigmatism after 3-month follow-up for 57.6% of patients

 Excellent Rotation Stability

 The same study also presents that AcrivaUD Toric has an excellent rotation stability in the capsular bag. Based on the mean axis deviation, 84% of all eyes had less than 3° rotation and all patients had less than 5° rotation after surger

2. Best Solution is Plate Haptic

Minimum SIA, Excellent Stability in MICS Design

Larger incisions cause surgically induced astigmatism and directly affect postoperative refractive outcomes. The AcrivaUD Toric Plate Haptic is the best choice, since it enables implantation through a sub-2.0-mm incision, minimizes surgically induced astigmatism and stays in the capsular bag without rotation.

Alignment of the AcrivaUD Toric lens on both sides makes rotation easier during the procedure. Holding on to posterior capsular bag at four points, plate haptic design always delivers excellent rotational stability

3. AcrivaUD Easy Toric Calculator

 Simple Tool For Toric Surgical Plan

 The AcrivaUD Easy Toric Calculator is developed for you to plan your surgery easily and to maximize the benefits of the selected toric lens.

4. Optimum Filtration Range

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 Sensitivit

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.

 

 

5. Premium Material

Best of Both Worlds!

The excellent material combination of 2-Oxiethylmethacrylate and 2-Hydroxymethacrylate monomers creates hydrophobic surface behavior with the advantage of hydrophilic flexibility.

Proven Hydrophobic Surface Behavior

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

Better Flexibility

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

 

6. 360⁰ All Square Enhanced Edge

Tolerance on
• biometry measurement deviation (±0,75 D post-op refractive suprises)
• slight post-op tilts
• higher kappa angle
Minimized dysphotopsia due to the reduced scattered light

 

Real 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.

7. Advantage of Ultra Definition 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.

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

8. 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.

9. 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.
