DIFFRACTIVA®
Combined technology
The DIFFRACTIVA® is a multifocal capsular bag IOL, developed for cataract patients who value a natural visual impression. It offers comfortable visual acuity at all distances: near, intermediate, and far. The design with balanced
light distribution is tailored to the everyday needs of patients and offers them clear visual advantages, especially under demanding light and contrast conditions.
DIFFRACTIVA® combines several optical principles:
| FAR | Diffractive-refractive optic design for excellent visual acuity in all lighting conditions |
| INTERMEDIATE | DOLA technology for optimized light use and reduced photic effects |
| NEAR | Near addition for an ergonomic reading distance |

More about the DIFFRACTIVA®
Multifocal premium IOL for
optimal presbyopia correction
DIFFRACTIVA® systematically combines the advantages of several optical principles to guarantee the most natural visual impression possible at all distances:
Diffractive-refractive optic design
The diffractive-refractive optic design achieves excellent visual acuity under both photopic and mesopic lighting conditions. The light distribution of the IOL is optimally regulated through the interaction of the illumination intensity and the pupil. Under photopic lighting conditions the light is balanced between the near and far range; in low light, the emphasis is on safety and far vision is more dominant. With a product adapted to their everyday needs, patients benefit from the best possible imaging conditions.
This is achieved by focusing the diffractive element on the central zone of the optic: This reduces glare to a minimum. The refractive edge area generates excellent distance vision under mesopic conditions and with dilated pupils, comparable to monofocal IOLs. This offers decisive safety benefits for the patient especially in low-light conditions.
Finely balanced
light distribution
The efficient light distribution of the DIFFRACTIVA® is tailored to the everyday needs of the patient.
Under photopic conditions and when pupils are constricted, the patient benefits from an even light distribution in the near and far range. The lower the light intensity and the larger the pupil, the farther the center of the light distribution shifts into the distance.
The gradual reduction of the diffractive element enables a smooth transition from near focus to far focus.
DOLA technology
DOLA technology (diffractive optic, local asphericity) generates an optimized visual acuity in the intermediate region with reduced photic phenomena. The optic design makes especially efficient use of the local asphericity of the individual stages of the diffractive element. The adapted asphericity extends the visual range with optimized light usage in the intermediate range. Glare phenomena and light loss, which often occur with polyfocal IOLs, can thus be significantly reduced.
Near addition
The central diffractive element with a near addition of 3.5 D enables comfortable near vision and meets all visual requirements at a physiological working distance of about 40 cm. With increasing age and progressive neuronal cell degeneration, vision deteriorates. The IOL concept of DIFFRACTIVA® considers the increased magnification requirement and compensates for it with optimal near addition.
Premium IOL-Diff-aA/-aAY
Your advantages of the premium IOL platform
Clinical results
For the highest patient requirements
The DIFF-aA captivates you with its excellent clinical results and high patient satisfaction.
Full patient satisfaction
Excellent visual results
Combined technologies, effective together
Binocular defocus curve
The defocus curve proves the excellent imaging properties of DIFF-aA/-aAY for far and near vision as well as the efficient use of DOLA technology for intermediate-range.
Excellent contrast sensitivity
Patients achieved better contrast sensitivity under photopic and mesopic conditions when compared to non-operated persons of the same age group.
Preloaded implantation system
SAFELOADER®
SIMPLE. INTUITIVE. FAST.
Separate components for maximum safety
The contactless preloaded implantation system offers a maximum of safety due to separation of the components. Both the IOL and the injector undergo separate sterilization processes. The isolated storage of the IOL ensures that it only comes into contact with the coating additives of the cartridge immediately prior to the surgery.
Easy to use: maximum flexibility
Another strength of the SAFELOADER® lies in its uncomplicated usage. The two-component autoloading system offers individual flexibility in the OR: combine the premium IOL of your choice with the desired incision size of the respective injector for minimally invasive implants (MICS).
