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	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.

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.

Your advantages of the premium IOL platform

High-precision manufacturing technology (Sub-nano resolution technology) enables the exact manufacturing of diffractive steps with an accuracy in the nanometer range. The result of this cutting-edge technology is an optic surface of premium quality for brilliant, clear, and sharp images.

360° lens epithelial cell barrier and sharp optical edges offer effective prevention of postoperative posterior capsular opacification.

Flexible material properties allow minimally invasive, astigmatism-neutral implantation (MICS).

The IOL material is modeled on the natural lens and has been clinically proven for nearly two decades. It is completely glistening-free and shows excellent uveal biocompatibility.

DIFFRACTIVA® is also available with a blue light filter for additional protection of the retina from shortwave light.

Our premium IOLs are developed and produced exclusively in Germany according to the strictest quality specifications and stand for the highest quality with maximum product safety.

For the highest patient requirements

The DIFF-aA captivates you with its excellent clinical results and high patient satisfaction.

Full patient satisfaction

100% of study patients were either very satisfied or satisfied with their vision.

92% of the study patients achieved spectacle independence after implantation of the DIFF-aA.
96% of patients did not experience or feel bothered by photic phenomena.

Excellent visual results

100% of patients achieved uncorrected far and near vision ≥0.8 decimal

83% of them reached a far and near uncorrected visual acuity of at least ≥1.0 decimal
83% of the patients achieved an intermediate visual acuity of ≥0.8 decimal

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 optimized light use 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.
