Light Filtration – Efficient Photoprotection

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.

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.

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

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.
