Contemporary testing of modern intraocular lenses in research and development.
With the new OptiSpheric® IOL R&D, TRIOPTICS GmbH offers the perfect prerequisite for testing state-of-the-art intraocular lenses according to ISO 11979 in research and development.
IOL manufacturers are continuously developing new lens models according to modern technological standards. TRIOPTICS now supplies the perfect solution for testing these new developments in accordance with ISO 11979: the new OptiSpheric® IOL R&D.
As a specialist for research and development, the OptiSpheric® IOL R&D impresses with its flexibility. All modern lens designs (monofocal, multifocal, trifocal, toric, aspheric as well as those with extended depth of field (EDOF) – each diffractive, refractive or sector lens) can be checked for important parameters such as refractive power, modulation transfer function and MTF focus scan, orientation and orthogonality of the cylindrical axis of toric lenses, curvature radii and section width. The manufacturing quality can also be visually assessed by the built-in camera. “The design of the device meets all the requirements of ISO 11979 – including an integrated real cornea,” emphasizes product manager Dörte Zimmermann. “In this way all evaluations of the newly developed IOL can be carried out in accordance with the standards.
In addition to the pre-programmed test processes described in the standard, the software also enables individual measurements. “This gives the customer full control over which parameters are measured and how,” explains Zimmermann. “These test processes can also be easily saved so that they can be repeated at a later point in time, e.g. on other lenses, or the test condition can be changed.
The OptiSpheric® IOL R&D provides the freedom to use the cornea and filters to ensure that the lenses also meet the practical requirements of the patient’s eye. “Both spherically aberrated corneas and illumination filters for 644 nm, 546 nm, 480 nm and photopic illumination simulate real imaging conditions,” says Zimmermann. During lens implantation, perfect positioning is not always achieved. The effects of these practice-relevant shifts and tilting can be simulated with the model eye for R&D. The results can contribute to the optimization of the lens design, even with incorrect positioning.
With the Model Eye R&D, the OptiSpheric® IOL R&D allows the standard-compliant and practice-oriented inspection of intraocular lenses.
Since both the measuring method and the software are based on the basic framework of the OptiSpheric® IOL PRO 2, the results of the scrap analysis and the necessary measuring processes can be easily transferred from development to quality control in series production. This facilitates the initial evaluation processes in production and ensures the comparability of all results.
