VSY Biotechnology has announced the launch of Enova, a 100% glistening-free IOL. The company says Enova is the first 100% glistening-free hydrophobic acrylic IOL that does not require pre-hydration or storage in saline solution.
VSY say the unique composition of Enova material allows uniform hydration of specific sites to have controlled water uptake and resistance to glistening formation. Glistening study was performed at the Intermountain Ocular Research Center (Mamalis/Werner Laboratory), John A. Moran Eye Center, University of Utah and the unique composition of Enova hydrophobic acrylic IOL shows no glistening compared with other IOLs.
“Enova is the first 100% glistening-free hydrophobic acrylic IOL that requires neither pre-hydration nor storage in saline. Enova is packaged dry and has excellent optical and mechanical properties,” said a company spokesman. “Glass transition temperature of a polymer is the temperature where the polymer changes from a rigid material to a soft material. Having a Tg -2°C, Enova IOL has gentle and controlled unfolding process below standard operating room temperatures. Thus, no warming or special conditioning is required. Low glass transition temperature (Tg -2°C) combined with its optimised modulus of elasticity, provides a high level of flexibility and controlled unfolding,” said the spokesman.
