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 |

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.
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.
Premium IOL-Diff-aAY
The advantages of the premium IOL platform
High-precision manufacturing technology (Sub-nano resolution technology) enables the manufacturing of diffractive steps to a precision of 0.1nm, which gives the product a smooth optical surface for 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 for micro-incision implantation (1.8mm)(MICS).
Preloaded implantation system: SAFELOADER®makes implantation easy and efficient.
The material of the IOL is close to the refractive index of the lens of the natural human eye. .MICROCRYL® has no glistening and good 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 with high quality production standards.according to the quality specifications.
