DIFFRACTIVA® – The IOL for vision at all distances
As we age, our visual acuity at close range slowly decreases and reading without glasses is no longer possible. Even after the successful treatment of cataract with a standard IOL, reading glasses are usually still required.
The DIFFRACTIVA® by HumanOptics is a premium IOL that enables natural visual impression without glasses through the effective combination of innovative technologies.
As the manufacturer of these lenses, we offer you comprehensive information on how our medical product works on this page. Your doctor will be happy to advise you on your individual situation and select the most suitable implant based on your needs and medical criteria.
How does the optical principle of DIFFRACTIVA® work?
DIFFRACTIVA® is produced in an elaborate manufacturing process. Within the process, special structures that look like rings are created on the optic (see illustration). When viewed at a much larger magnification, these structures look like stepped rings, the precise height and distance of which are crucial for visual quality. Due to this structure, a sharp image of objects at different distances is given.
How is the visual impression with the DIFFRACTIVA® in everyday life?
The innovative DIFFRACTIVA® concept has been specially developed for the needs of patients in their daily lives.
The human pupil changes its diameter dynamically depending on light conditions and visual requirements. The ring structure of DIFFRACTIVA® is optimized so that its effect harmonizes with the natural pupil opening.
In darker light conditions, the pupil is dilated and the entire optical range is used: both the central ring field and edge area without rings. This supports distance vision, which is particularly important in poor lighting conditions, such as when driving a car at twilight.
Close-up vision, such as reading, usually takes place with bright illumination and a small pupil. Automatically, only the IOL ring area required for close vision is used. The DIFFRACTIVA® is optimized for everyday working distances. Daily visual tasks, such as recognizing prices in the supermarket or operating a mobile phone, are convenient without glasses. For example, a study patient (73 years old) reports: “I am so satisfied! I can thread a hair through a sewing needle.”
The DIFFRACTIVA® is specially adapted to various lighting situations encountered in everyday life, which enables comfortable vision in the most diverse daily activities. A 78-year-old patient confirms this: “My vision is perfect. I have the eyesight of a 30-year-old woman again.” Read more
