Based on the patented “Phase Shifting Schlieren” (PSS) method, the NIMO TR0815 measures every type of refractive intraocular lenses, whether wet or dry, monofocal, toric, multifocal or multifocal toric.
Through its advanced technology, the NIMO offers the highest resolution amongst all commercially available power-mapping instruments, providing power and full wavefront characterization with matchless repeatability and reproducibility. Routine calibrations are no longer necessary and the software offers a user-friendly interface with plenty of options and full traceability.
