HOW DO I SEE AFTER A REFRACTIVE LENS EXCHANGE? – EXPERIENCE YOUR FUTURE IOL VISION PRIOR TO IMPLANTATION

DEZIMAL GmbH is an innovative start-up with cutting edge solutions in presbyopia treatment.
DEZIMAL emerged from a cooperation between ACMIT Gmbh, an Austrian research and development center specialized in medical technology and biomedical optics, and 1stQ Deutschland GmbH, an intraocular lens manufacturer with 30 years of experience in the IOL business under the guiding vision of 100% predictability in refractive lens exchange.
Our product RALV (Real Artificial Lens Vision) is a novel, optical system for precise predictability of achievable vision after refractive lens exchange.
It allows accommodation-impaired patients to see preoperatively through real intraocular lenses (IOLs) to experience postoperative vision with an IOL prior to implantation. The technology is unique as it offers the view through the IOL with a large field of view through an optical lens system. The optical system “neutralizes” the natural lens of the patient and thereby accounts for the spherical and chromatic aberrations of the pseudophakic eye. The result is an immersive and optically correct experience of the pseudophakic vision. A set of qualitative and quantitative vision tests (including a novel quantitative halo/glare test) have been realized to support the selection of an IOL (i.e. monofocal, EDOF, mulifocal) in terms of subjective assessment to achieve maximum patient satisfaction after lens exchange.
Motivation:
- Trend towards freedom from glasses in old age
- Freedom from glasses can be achieved through multifocal intraocular lenses (MIOL)
- Individual tolerance of multifocal IOLs with no predictability
- Currently insufficient patient education by means of computer simulations and photomontage that does not reflect subjective visual impression
Benefits of RALV for physicians, patients, and lens manufacturers:
- increased access to MIOL technology
- selection of the individually best IOL by experiencing the postoperative visual impression
- realistic patient expectation
- patient satisfaction
- self-determined decision of the patient
- fewer complaints (i.e. fewer explantations)
- simple and understandable preoperative patient education
- improved communication between physician and patient
- safety for physician and patient by monitoring the quality of the implantation through pre- and postoperative eye tests (visual aquity, contrast sensitivity, halo/glare test)
- reproducible results through standardized process
- easy and fast testing for the development of new lens designs
- possibility for IOL studies without actual implantation
