The Staining Grid
is an easy-to-use reference tool informing the eye
care practitioner as to the level of biocompatibility of various
contact lens/multipurpose solutions. It appears as a "grid" with
the solutions listed across the top and the lens materials in the
first column. The percentages which appear in each cell represent
the average percentage of the cornea which was stained 2 hours
after lens/solution insertion. For information on our testing procedures
please see the methodology
question in the Frequently Asked Questions section
of this site.
To choose a biocompatible multipurpose solution for a particular lens brand:
Find the lens material (if it has been tested) in the first column of the grid.
Follow across that row and select a solution which results in minimal corneal staining (i.e., green zone).
Note: Clicking on a percentage inside a cell of the Grid gives more information about that particular study's results.
