OptiSpheric® IOL R&D - Extensive Testing of Intraocular Lenses in Research and Development

IOL Testing in R&D in accordance with ISO 11979
IOL Testing in R&D in accordance with ISO 11979

The OptiSpheric® IOL R&D is specially designed for the analysis of single intraocular lenses in research and development. With the OptiSpheric® IOL R&D, important parameters of all types of lenses (monofocal, multifocal, trifocal, toric, aspheric and those with extended depth of focus (EDOF) – whether diffractive, refractive or sectors) can be measured and tested in air or in situ in accordance with ISO 11979. The comprehensive range of accessories and multiple adjustment options ensure precise and diverse measurements of all aspects that are crucial when developing a new lens design. For example, the imaging properties of the IOL are simulated in a tilted or decentered lens position after implantation.

The software is just as flexible as the hardware: individual, user-defined test processes can be performed or standard procedures stored for repetition at a later time.

Key Features

  • Optimized for use in research and development
  • Measurement accuracy of 0.3 % and high repeatability
  • Standard-compliant measurement of hydrophobic and hydrophilic lenses in air or in heatable in situ model eyes in accordance with ISO 11979
  • Multiple adjustment options for extensive testing with various corneas and filters
  • Easy measurement and testing of refractive power (nominal value for sphere, cylinder and addition), EFL and MTF through automated precise autofocus
  • Universally suitable for all types of intraocular lenses: monofocal, spherically aberrated lenses, multifocal, trifocal, toric and aspheric IOLs and those with extended depth of focus (EDOF) (diffractive, refractive or sectors)
  • Immediate evaluation of the measurement result with corresponding display through quality control with pass/fail analysis
  • Traceability to independent international testing and measurement institutes such as NPL and NIST
