The Visual Effect of an Investigational Artificial Tear in the Tear Layer.

• Status: Completed
• Trial end date: 2007-09-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to investigate how the addition of a new artificial tear product when applied to the tear layer affects contrast sensitivity and optical aberrations over time. We will also determine if there are any adverse effects associated with drop instillation.

• Phase: N/A

Criteria

Inclusion Criteria:

• Thirty subjects free from ocular pathology will be chosen. Ten of the subjects will have a normal tear layer, ten will have a mild dry eye, and ten will have a moderate/severe dry eye. All subjects will be over the age of 18. Best corrected visual acuities will be at least 20/25 on a standard Snellen acuity chart at distance.

Exclusion Criteria:

• Subjects will be excluded from this project if they have, or during the course of the experiment they develop, an allergy to the eye drops used in this project.
