Evaluation of Disinfecting Solutions and Protein Remover With a Silicone Hydrogel Lens

The purpose of this study is to determine if reduced lens deposits and increased comfort can be achieved by using Multipurpose disinfecting solutions (MPDS) in a no-rub format but in conjunction with an intensive cleaner, rather than using MPDS in a rub format by observing changes within the cornea and collecting subjective ratings.
