The Physiological Consequence of Silicone-hydrogel Care-solution Bio-incompatibility
Completed · Not applicable
Conditions studied: Contact Lens Solution Toxicity
In brief
The purpose of this study is to more objectively evaluate potential lens-material/care solution bio-incompatibilities. We will do this by measuring corneal staining and the amount of fluorescein dye diffusion into the eye.
