Trial Outcomes & Findings for Evaluation of the Effectiveness of Two Marketed Multi-Purpose Solutions for Silicone Hydrogel Contact Lenses - Study 1 (NCT NCT01684033)

NCT ID: NCT01684033

Last Updated: 2014-04-17

Results Overview

Corneal staining in both eyes was assessed during slit lamp examination using flourescein dye. Each of five corneal regions (central, nasal, temporal, inferior, and superior) was graded on a scale from 0 (none) to 4 (patch). The corneal fluorescein staining score was calculated as the total of the five regions. The score ranged from 0 (no staining in any region) to 20 (patch staining in all five regions). The corneal staining of the worse eye was analyzed.
