ARTIS®
4 reasons to prefer the new mat erial Cristalens
1 Faster unfolding, better control
3 Transparent material
Due to the presence of significant vacuoles in a lens, light diffusion increases as the angle of
incidence of the light approaches the normal.
Deployment time
The gradient of the curve shows the unfolding
time against temperature.
In practice, above 30 °C in a cohesive OVD, complete unfolding (optical and haptic) is achieved in:
10 000

> 15 seconds for a hydrophilic iol
> 22 seconds for the hydrophobic Cristalens
> 62 seconds for a hydrophobic lens manufactured
by the competition

If the pressure required for injection is low, the entire
implant positioning process is simplified:
> regular effortless sliding
> controlled unfolding of the implant
> positioning of the haptics at the required position

1 Anatomic conditions for precise, stable refraction
• A single iol diameter does not take into
account the high variability in lens diameters:
8.25 to 10.80 mm.
ARTIS®: design better adapted to variations
in bag diameter
The experiment conducted in wells and on bank eyes (views in Miyake Apple,
Liliana Werner laboratory, Salt Lake City) has demonstrated the ADAPTABILITY
of the ARTIS® design.
• In 9 to 10 mm wells, corresponding to the largest number of diameters encountered
in clinics, the loops deform with no anterior or posterior angulation, keeping
the same contact arc.
• This diameter does not always vary with
the axial length, the implant must therefore
adapt to the bag diameter and not the
opposite. This condition is required to
guarantee the precision and stability of
the refractive result.
>> The implant adapts to the bag
diameter to ensure centration and
correct position on the optical axis.
• An implant which adapts to variations in
capsular bag diameter will be better
positioned in the ciliary diaphragm and
on the optical axis.

• An implant which adapts to the bag (and not the opposite)
will be better centered in the bag and better positioned on
the optical axis at the required position.
