"I see what I will see"

Preoperative intraocular lens measurement by RALV

Clear vision and full participation in life. Presbyopia affects millions of people and can significantly restrict everyday life. The ability to see clearly again therefore fundamentally changes the lives of those affected. Surgically inserted intraocular lenses (IOLs) offer a permanent solution that goes far beyond conventional vision correction. With the RALV (Real Artificial Lens Vision) system developed by DEZIMAL GmbH, patients now have the opportunity to test and personally evaluate different types of lenses before surgery. This innovative method makes it possible to precisely select the optimal IOL for each patient. This not only maximizes patient satisfaction, but also significantly reduces the risk of reoperations. With our expertise in the conception and design of complex medical devices and their handling, we were able to help make the operation of the system even more intuitive and optimize the interaction process.

Precise and clear

The RALV project pursued the ambitious goal of developing an innovative examination unit that enables patients to precisely predict their future vision with an intraocular lens. This high-performance technology sets new standards in ophthalmology. When designing the system, the principles of precision, clarity and minimalism were at the heart of the design concept. Essential factors to ensure that the result is not only technologically advanced, but also intuitive and trustworthy for the user.

Confidence through design language and ergonomics

Based on the technological innovation developed by DEZIMAL GmbH, particular emphasis was placed on the user-friendliness of the system. RALV was developed in such a way that it offers patients the opportunity to experience their future visual performance with the intraocular lenses in a realistic way, taking away much of the uncertainty before the sensitive procedure. As no ophthalmologist can predict with absolute certainty what a patient's vision will be like with an artificial lens, only the patient themselves can judge this. For this reason, it was crucial that the design language of the device not only inspires confidence in the technology and is easy to use, but also provides a positive and reassuring experience during use.

During the design process, great emphasis was placed on optimal usability to ensure that patients feel confident and safe when using the device. By using early low-fidelity prototypes, we were able to thoroughly test ergonomic adjustments, component proportions, device orientation and subjective perception. The goal was to create an intuitive and inviting user experience characterized by clear, trustworthy design features and user-friendly ergonomics.

Innovation through cooperation

The close collaboration with the experts of the DEZIMAL team was a decisive factor for the formal quality of RALV. Through an intensive design process that included numerous sketches, mock-ups and simple prototypes, the product architecture and design language was developed. This process resulted in a minimalist and expressive device that is safe and easy to use for both patients and clinicians.

WILDDESIGN Part

Innovative design concept
Detailed workflow analysis
Ergonomics and usability studies
Iterative design process

"The WILDDESIGN team was the perfect choice to bring the technological innovation of our development into a user-friendly and very high-quality form. This makes it possible for the first time for patients to select the best IOL for them individually according to their actual visual impression before implantation, in order to avoid potential incompatibilities with multifocal intraocular lenses and maximize patient satisfaction.

We are convinced that we have created a unique SYSTEM in the field of intraocular lens fitting."
