Trial Outcomes & Findings for Comparison of Two New Silicone Hydrogel Multifocal Products (NCT NCT00823615)

NCT ID: NCT00823615

Last Updated: 2012-06-29

Results Overview

Tested while reading charts distant to the subject with both eyes together in normal lighting. This outcome is measured in logMAR units (logarithm of the minimum angle of resolution). A logMAR acuity of 0.0 equates to 20/20 Snellen acuity and is considered normal. Positive logMAR values indicate poorer vision and negative values denote better visual acuity.

PRIMARY outcome

Timeframe: After 1 week of wear

Population: Per protocol. Analysis excluded major protocol deviations as determined by masked review.

Tested while reading charts distant to the subject with both eyes together in normal lighting. This outcome is measured in logMAR units (logarithm of the minimum angle of resolution). A logMAR acuity of 0.0 equates to 20/20 Snellen acuity and is considered normal. Positive logMAR values indicate poorer vision and negative values denote better visual acuity.

PRIMARY outcome

Timeframe: After 1 week of wear

Population: Per protocol. Analysis excluded major protocol deviations as determined by masked review.

Tested while reading charts at 40 cm with both eyes together in normal lighting. This outcome is measured in logMAR units (logarithm of the minimum angle of resolution). A logMAR acuity of 0.0 equates to 20/20 Snellen acuity and is considered normal. Positive logMAR values indicate poorer vision and negative values denote better visual acuity.
