VSY Biotechnology Discovers How to Connect the Golden Ratio Concept to its New Intraocular Lens Technology
VSY Biotechnology said its trifocal technology has created an IOL that has virtually the same conditions as the natural refraction of light waves in the human eye.
Two features of the Acriva Trinova Pro C Pupil Adaptive lens that make it different and unique from other products on the market are the Sinusoidal Vision Technology (SVT) and the Pupil Adaptive Design, according to VSY Biotechnology. SVT provides uninterrupted vision at all distances by minimizing light loss as well as artifacts created by scattered light such as halo and glare. Pupil Adaptive design optimizes lens performance in different light conditions by mimicking the physiological behavior of the eye. The Acriva Trinova Pro C Pupil Adaptive has the highest retinal light utilization of any trifocal IOL available, preserving visual performance by 93%, and is the closest lens to a crystalline lens, thanks to its stepless diffraction zones that greatly increase contrast sensitivity, according to a company news release.
"Instead of conventional sharp sawtooth patterns, the Acriva Trinova Pro C Pupil Adaptive with Sinusoidal Vision Technology (SVT) utilizes smooth, step-less refractive pattern projections without creating any discontinuities in the lens. This significantly decreases unfocused, scattered light and optimizes light distribution. Instead of using different pitch heights for vision at a variety of distances, as is the case with most lenses on the market, SVT-based lenses’ sinus waves’ optical profile distributes light effectively across near, intermediate as well as far distances. The SVT adapts to changes in pupil size, thus ensuring spectacle independence from photopic to mesopic conditions while providing clear vision at every relevant focal point," according to VSY Biotechnology.
While the Golden Ratio provides perfect proportion and harmony in nature, AcrivaUD Trinova Pro C Pupil Adaptive is the only IOL technology that has virtually identical conditions to the natural refraction of light waves in the human eye. AcrivaUD Trinova Pro C Pupil Adaptive provides clear vision at all distances and in all light conditions, ensuring patient’s ability to perfectly view road signs, drive safely at night, view computer screens and mobile devices with ease, and comfortably read even with subdued lighting.
