100% Glistening-Free Hydrophobic Acrylic

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 and Zero Haze1 even under extreme conditions compared with other IOLs.

 

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.

 

DRY-PACKED hydrophobic IOL with maximum controlled water intake

 

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.

 

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

 

2 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.

 

 

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.

 

High Light Transmission

Enova® with the hight light transmisson provides high visual quality in the far distance.

Spectral trasnsmittance curve of a 20.00 D IOL, UC cut-off at 10% is about 378nm

 

High MTF Values

Modular Transfer Function (MTF)

MTF is a direct and quantitative measurement of optic system quality. VSY Biotechnology established its own criteria for Quality Control: Average MTF valu must be above 0.60. According to international standarts the MTF result at an IOL must be above 0.43 at 100 lpm.

MTF (Modular Transfer Function) of Enova® IOL is (for 3 mm and 4.5 mm aperture) compared to 3 mm aperture ISO Standard model. As figure shows, the MTF of Enova® is well above the ISO Standard.
