Trial Outcomes & Findings for An Evaluation of Marketed Contact Lens Disinfectant Systems on Eyelid Tissues (NCT NCT01594294)

NCT ID: NCT01594294

Last Updated: 2014-07-25

Results Overview

Eyelid papillae (bumps on the inner eyelid) were recorded separately for three zones of the upper lid and overall for the lower lid on a 5-point forced choice scale: 0 = None; 1 = Slight (diffuse papillae); 2 = Mild (diffuse \& tufts papillae); 3 = Moderate (moderate \& tufts papillae); 4 = Severe (giant papillae). The maximum value represents the worse grade in any zone. Both eyes were included in the model for analysis. Contact lenses were not worn for this assessment.

Population: This analysis population includes all participants who completed the study as per the protocol, minus missing responses.

Eyelid hyperaemia (redness) was recorded separately for three zones of the upper lid and overall for the lower lid on a 5-point forced choice scale: 0 = Clear; 1 = Slight redness; 2 = Mild redness; 3 = Moderate redness; 4 = Severe redness). The maximum value represents the worst grade in any zone. Both eyes were included in the model for analysis. Contact lenses were not worn for this assessment.

Population: This analysis population includes all participants who completed the study as per the protocol, minus missing responses.

The contact lenses were removed and upper eyelid redness was objectively measured through digital images. The coverage of the palpebral surface by blood vessels is expressed as percentage of the total surface measured. Both eyes were included in the model for analysis. Contact lenses were not worn for this assessment.

The contact lens was removed and ophthalmic dye was instilled. Upper eyelid margin staining was objectively measured through digital images. The extent of true staining (i.e., the total area of lid margin covered by staining) was recorded. Both eyes were included in the model for analysis. Contact lenses were not worn for this assessment.

SECONDARY outcome

Timeframe: Month 3

Population: This analysis population includes all participants who completed the study as per the protocol, minus missing responses.

The pre-lens tear film is the layer of tears located on top of the contact lens (i.e., between the eyelid and the contact lens). The time required for a dry spot to appear on the pre-lens surface after blinking is referred to as the pre-lens tear film break up time. PL-NIBUT was evaluated using a biomicroscope with a diffuse illumination source, i.e., Tearscope. A longer PL-NIBUT indicates a more stable tear film and greater on-eye lens wettability. Three PL-NIBUT measurements were recorded, and the median value was used for analysis. Both eyes were included in the model for analysis. Contact lenses were on-eye for this assessment.
