Evaluation of Corneal Staining With Market Contact Lens/Solution Combinations

The purpose of this study is to quantify the amount of corneal staining observed with
various marketed contact lens/multipurpose solution combinations. The hypothesis is that
there are measurable differences in the amount of corneal staining between the various
combinations.

A series of clinical studies is being conducted at one research site using a double-masked,
randomized cross-over design. Each study consists of asymptomatic daily wear soft contact
lens wearers observed at baseline and at two and four hours post lens insertion. Corneal
staining is being assessed using sodium fluorescein, a cobalt filter and a yellow filter.
Subjective comfort assessments are obtained at each visit.

Inclusion Criteria:

- currently wearing soft contact lenses daily wear for at least 2 weeks prior to study

- correct visual acuity of 20/30 or better each eye

Exclusion Criteria:

- history of hypersensitivity to any components of solution being tested

- any ocular condition prohibiting contact lens wear

- excessive baseline staining as defined in protocol

- use of topical or OTC ocular medications during the study

- seasonal allergies with significant effect on contact lens wear
