Abstract

Optical characteristics of the multifocal intraocular lens (IOL) are different from regular monofocal IOLs. We have developed a test method and procedure to measure completed optical performance of the AMO Array^TM multifocal IOL and to control its optical quality. The measured parameters include effective focal length, aqueous diopter power, add power, depth-of-focus, resolution efficiency, contrast modulation for far and near image, subjective quality factor variance , and through focus response. Automated Inspection Station was developed to perform the measurements. In addition, surface characteristics of the multifocal IOL are measured by a special custom-built interferometer (Wavy Optical Tester).
