RALV® by DEZIMAL is a non-invasive optical device for precise predictability of achievable vision after refractive lens exchange.
RALV allows presbyopic patients to see through real intraocular lenses and experience postoperative vision prior to implantation of the IOL.

The goal of RALV is to achieve the highest possible patient satisfaction after refractive lens exchange - less complaints and less explantations.
RALV allows to “test” an IOL on objects and vision charts in near, intermediate and far distances, allowing patients to subjectively evaluate different IOL types and designs (monofocal, EDoF, multifocal - refractive and diffractive) to find the one that individually fits best. Likewise, RALV supports selecting the right candidate for a certain type of IOL.
