Abstract

An automated inspection station is a specifically designed for quality assurance inspection of multifocal intraocular lenses in the manufacturing environment. The station provides automatic measurements for all required optical parameters of the AMO ARRAY^TM multifocal IOL, which includes labeling parameters such as effective focal length, aqueous diopter power (distance power), add power (near power), and depth-of-focus (DOF) around the distance power, and optical quality parameters such as resolution efficiency, image contrast modulation (MTF), through focus response (TFR), and astigmatism.
