Surface Residual Process Improvement

Abstract

A manufacturing plant dedicated to the production of intraocular lens is observing a significant number of defects in their operations which has led to a decrease in the manufacturing yield. The project objective is to increase the yield and reduce the surface residual defect. Different techniques were applied to determine the root cause of the problem. The root cause was attributed to procedures not standardized and lack of materials. The actions implemented as part of this project were procedure standardization and purchase of materials. After actions were implemented, the surface residual reject rate was reduced by 1.35 % and the manufacturing yield was increased by a 1.5% meaning that the project objectives were accomplished. Key Terms ⎯ Cataract, Intraocular Lenses, Process Improvement, Yield Increase.
