Auroflex EV

Auroflex EV is a negative aspheric hydrophilic acrylic foldable intraocular lens made of p-HEMA material which is a polymer that forms hydro gel in water, is mainly designed to correct the corneal aberration during cataract surgery and provide enhanced vision.

Product features:

Anterior spherical and posterior aspheric optic
Optically designed to compensate the average corneal SA of majority of human population
A negative spherical aberration of -0.15ľ is allowed to:
- Suit cornea of majority of the global population
- Imitate results of the young natural crystalline lens
- Provide enhanced depth of focus & contrast sensitivity
- Better performance of visual acuity during mesopic and scotopic conditions
Can withstand a tilt of 10 degree and decentration of 1.0mm
Truedge technology to prevent PCO
Anterior round edged polishing to avoid glares
Dual haptic design ensures better stability and centration

MTF comparison of Aspheric IOLs and Standard spherical IOLs. Analysis shows that the IOL functions, similar to the standard spherical IOLs when tilted or decentered beyond tolerances.

The illustration shows that the longitudinal spherical aberration is least with negative aberration aspheric IOLs. This results in better contrast sensitivity than standard spherical IOLs and zero spherical aberration IOLs.

FAQ’s

1 .What is an aspheric IOL?
- Aspheric IOl is an IOL meant to correct the spherical aberration of an optic system.Traditional lenses are spherical, which means the surfaces are uniformly curved, but in aspheric lenses anyone of the surface is not spherical to provide better contrast sensitivity.
2. What are aberrations?
- Aberration is defined as an imperfection in image formation in an optical system. An ideal lens will focus all parallel rays to a single point. Practically no system (including natural crystalline lens) is perfectly aligned and they have some amount of aberrations.
3. What is the advantage of implanting Auroflex EV in the eye?
- Auroflex EV is designed and engineered with the negative aberrations in relation to the existing corneal positive aberrations. Thus the resultant vision will be close to the natural lenses ie. Glare free and enhanced vision
4. How does Auroflex EV compensate cornea natural aberration?
- Human cornea is positively aberrated, avg value about +0.27ľm.Young human lens is negatively aberrated, to compensate the negative aberration in cornea. Due to aging factor natural lens will become positively aberrated (cataract patients) and thus leads to poor vision. Auroflex EV is designed similar to the natural crystalline lenses and thus compensates the aberration in the cornea and provide a improved contrast sensitivity
5. Will decentration of Auroflex EV affects the quality of vision?
- Auroflex EV is designed to withstand the tilt of 10° of decentration. So the decentration of auroflex EV will not affect the image quality.
