4 reasons to prefer the new material Cristalens
Faster unfolding, better control
Optimised refractive index
Transparent material
Positioning in the capsular bag easier to control
ARTIS® The only hydrophobic iol which is injected in a 1.8 mm diameter cartridge
Reflectance and index contrast
The gradient of the curve shows the unfolding time against temperature.In practice, above 30 °C in a cohesive OVD, com-
plete unfolding (optical and haptic) is achieved in:
> 15 seconds for a hydrophilic iol
> 22 seconds for the hydrophobic Cristalens
> 62 seconds for a hydrophobic lens manufactured
by the competition
Due to the presence of significant vacuoles in a lens, light diffusion increases as the angle of
incidence of the light approaches the normal.
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
In a 2.2 mm diameter cartridge, the injection pressure
of our material is 1.8 kg. Other hydrophobic materials
require a pressure of 2.6 to 3.8 kg.
In a 1.8 mm cartridge, we are at 2.2 kg, when no other
hydrophobic material can be injected.

New design
Anatomic conditions for precise, stable refraction
ARTIS®: design better adapted to variationsin bag diameter
• A single iol diameter does not take into
account the high variability in lens diameters:
8.25 to 10.80 mm.
• 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.
• An implant which adapts to variations in
capsular bag diameter will be better positioned in the ciliary diaphragm and
on the optical axis.
>> The implant adapts to the bag
diameter to ensure centration and
correct position on the optical axis.
>> With better centration and no
tilting of the haptics or the optics.
The experiment conducted in wells and on bank eyes (views in Miyake Apple,Liliana Werner laboratory, Salt Lake City) has demonstrated the ADAPTABILITYof 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.
• 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.
>> Diameter variation induced by the implant.
