ACMIT and its partners are pleased to announce the publication of a new prospective clinical study entitled “Leistungsbewertung eines Sehsimulators für Intraokularlinsen”, published in the journal “Die Ophthalmologie”.
The study evaluates the performance of the optical system RALV (Real Artificial Lens Vision © DEZIMAL GmbH) in predicting postoperative visual outcomes for patients undergoing refractive lens exchange.
In recent years, intraocular lens (IOL) simulators have become increasingly important tools for preoperative patient counselling and for assessing acceptance of different lens options. The RALV device represents a novel approach, allowing patients to experience vision through a real, commercially available IOL even before implantation.
The study evaluated how accurately RALV can simulate postoperative vision in patients receiving trifocal IOLs by comparing preoperative simulations with postoperative outcomes, including visual acuity and contrast sensitivity at all distances, as well as halo and glare perception.
Results showed a strong statistical agreement between RALV predictions and postoperative outcomes, with deviations within clinically acceptable limits (≤ ±0.10 logMAR for visual acuity and ≤ ±0.25 logCSWeber for contrast sensitivity). Halo and glare measurements also demonstrated close agreement within ±4.55 mrad.
These findings confirm that the RALV system provides a reliable and clinically relevant preview of postoperative vision with trifocal IOLs, supporting improved patient counselling, shared decision-making, and greater predictability in refractive lens exchange.
