ENHANCED QUALITY
OF VISION
IOL manufacturers eagerly compete for
superior intermediate performance or compress
the addition towards the intermediate to create
some „comfort“. While doing this they disregard
the main key of success for multifocal IOLs –
SPECTACLE INDEPENDENCE.
Medicontur chooses not to compromise
IOL performance.
Liberty equates to spectacle independence
without the compromise of reduced image
quality or visual acuity at near and far distances.
LIBERTY
FOR YOUR PATIENTS
THE MOST BALANCED
TRIFOCAL IOL
Less Diffractive Steps – More Vision
Light is scattered within an IOL by every diffractive step. Considerable additional light
scattering is caused by the manufactured imperfections of these steps on multiple points.
Therefore not only the quality but also the quantity of the manufactured steps has
a great impact on light scattering and loss of light energy.
The below symbolic figures demonstrate the difference in light scattering and energy loss
on two separate diffractive IOL profiles.

What does LESS STEPS mean for your patients?

A TRIFOCAL DESIGN:
Elevated Phase Shift * (EPS) technology
Medicontur‘s proprietary, patented approach to trifocality uses EPS in the central part
of the optic to generate constructive interference between the 0th (far) and 1st (near)
diffractive order. This revolutionary optical design generates the 3rd focal point for
intermediate vision in a very unique way:
THE MOST BALANCED
TRIFOCAL IOL
EPS* technology uses only 7 rings within a 3 mm diameter for complete spectacle
independence, improved image quality and excellent performance at near and far.
7 steps to Trifocal perfection
LIBERTY IOLs achieve trifocal performance with
7 steps in a precise diffractive array within a
3 mm diameter leaving a
75% refractive lens surface.
LIBERTY IOLs are strongly pupil dependent using the NEAR TRIAD which implies miosis
under accommodation. We believe that too much light distribution into the near focus
above 3 mm aperture does not match normal ocular physiology.
The 4 charts below show the Useful Light Distribution in % of LIBERTY and 3 competitors
depending on the aperture [mm] *. LIBERTY provides the highest light distribution in the
near focus under accommodation and the highest for far vision under scotopic conditions.
