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 ArrayTM 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).
