OptiSpheric® IOL - Measurement of Intraocularlenses in Accordance to EN/ISO 11979

Advanced model eye for R&D applications
Advanced model eye for R&D applications

The OptiSpheric®IOL allows the measurement of all important parameters of intraocular lenses according to EN/ISO 11979. For any type of intraocular lenses (monofocal, multifocal, toric) with any type of structure (refractive, diffractive) or materials (PMMA, foldable, hydrophilic) it measures in air or in situ a wide spectrum of parameters.
