Slide Slide - 100% Glistening-Free - Dry-Packed - Next Generation Hydrophobic

Enova®  is the first 100% glistening-free hydrophobic acrylic IOL that does not require pre-hydration and storage in saline solution!


100% Glistening-Free Vision

What are Glistenings?

Glistenings are fluid-filled micro-vacuoles within the intraocular lens optic when the IOL is in an aqueous environment; they cause light scattering and may affect the quality of vision by reducing the contrast sensitivity and inducing undesirable optical artifacts. The unique composition of Enova®’s material shows Zero Glistening even under extreme conditions.

Glistening Formation in IOL

Water molecules bind to certain chemical groups through weak hydrogen bonds. Over time, more water molecules diffuse into the polymer network and bind preferably to other water molecules, which forms clusters referred to as “glistening”


Enova® 100% Glistening-Free IOL

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 Zero Glistening and Zero Haze compared with other IOLs. (1)

DRY-PACKED hydrophobic IOL with maximum controlled water intake



ST Generation IOLs
Acrylic IOLs develop various levels of glistening post implantation due to uncontrolled water sorption into the IOL polymers.

ND Generation IOLs
Hybrid polymers demonstrate a more controlled water uptake and significantly improved resistance to glistening formation. However, IOLs made from such materials have poor mechanical properties and require both pre-hydration and storage in saline.

Next Generation Hydrophobic 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.



Outstanding Biomechanical Properties

Glass transition temperature of a polymer is the temperature where the polymer changes from a rigid material to a soft material. Having a Tg of −2°C, Enova® IOL has gentle and controlled unfolding process below standard operating room temperatures. Thus, no warming or special conditioning is required.

Enova® IOL has low glass transition temperature (Tg −2°C) and optimized modulus of elasticity which provide a high level of flexibility and controlled unfolding.
