OneDay Toric Yield Improvement

Abstract

This project was developed in CooperVision, Juana Diaz Site, specifically for the OneDay Toric product. It is focused on the Wet Process of the product life cycle. There was a gap between two manufacturing technologies that manufacture the same product. The gap was around 5% in wet yield, given by the data from January 2021 to March 2021. In order to understand the difference better, the project was worked through the DMAIC methodology. Statistical tools were used to measure and analyze the process, and then brainstorming strategies were done in order to provide plausible solutions. An opportunity was identified in configuration file of the GenII+ vision system. The issue was addressed, and false rejects were reduced by 93%, thus increasing the product wet yield.
