Corneal staining relating to contact lens wear

This paper presents an overview of the common types of corneal staining that are encountered when wearing contact lenses. Included are descriptions of corneal staining occurring with rigid lenses (polymethylmethacrylate and cellulose acetate buterate), various types of hydrophilic lenses and silicone lenses. Specific patterns of sodium fluorescein staining are depicted and related to the various types of contact lenses.
