Two Phase Clinical Study of the Impact of Contact Lenses and Solutions on Corneal Structure

Several types of solutions are used in contact lens wear.

Each contact lens solution used to disinfect contacts have different ingredients even though
they all disinfect the contacts.

The objective of this study is to examine the layers of the cornea via HRT in order to assess
the usefulness of this technology and to identify any potential consequences of contact lens
wear and/or care solution used.

Inclusion Criteria:

- Vision correctable to 20/30 or better in both eyes

- Successful soft contact lens wear for at least 2 weeks prior to enrollment

Exclusion Criteria:

- History of hypersensitivity to any of the components in any of the lens solutions

- One functional eye or a monofit lens

- Any abnormal slit-lamp finding at baseline

- Use of topical ocular meds

- Any systemic condition with significant ocular side effects or that interfere with
contact lens wear

- Enrollment of the investigator's office staff, relatives or members of their
respective households

- Enrollment of more than one member of the same household
