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.
