Cataract surgery is the most frequently performed operation in the world. Therefore, the demand for intraocular lenses (IOLs) is continuously rising. In addition, patients’ expectations of implants are changing and are met by the development of premium lenses. Consequently, all IOL manufacturers are quickly advancing their research and development for new lens models. Additionally, they require efficient and high quality testing of their IOLs.
As for all medical products, IOLs have to be developed, produced and eventually tested in compliance with the applicable ISO standards. ISO 11979 is applied for IOLs. To fulfill these requirements, instruments for quality inspection of IOLs need to perform in-situ measurements with a physical model cornea and a model eye simulating natural conditions. Measuring parameters like lens aberrations and toric axis deviation or performing power mapping are also of great interest.
