Trial Outcomes & Findings for Performance of a Multifocal Contact Lens - Presbyopia Study (NCT NCT02450747)

NCT ID: NCT02450747

Last Updated: 2018-06-19

Results Overview

Hyperemia (Redness) was assessed using two different parts of the eye, the Bulbar and the Limbal. Hypemeria was measured using the Efron Scale in 0.5 step units. Grade 0= No Findings, Grade 1= Slight, Grade 2= Mild , Grade 3= Moderate and Grade 4 = severe. Hypermia was assessed in four regions of the eye (Inferior, Nasal, Temporal and Superior). The total grade of Conjunctival Hypermia across all regions and grades is reported. The total grade can range from 0 to 8. Where a higher grade implies worsening conjunctival hypermia

PRIMARY outcome

Timeframe: Baseline to 4-Week Follow-up

Population: The analysis population consists of all subjects that completed all study visits without a major protocol deviation. The analysis is conducted on subject eyes.

Hyperemia (Redness) was assessed using two different parts of the eye, the Bulbar and the Limbal. Hypemeria was measured using the Efron Scale in 0.5 step units. Grade 0= No Findings, Grade 1= Slight, Grade 2= Mild , Grade 3= Moderate and Grade 4 = severe. Hypermia was assessed in four regions of the eye (Inferior, Nasal, Temporal and Superior). The total grade of Conjunctival Hypermia across all regions and grades is reported. The total grade can range from 0 to 8. Where a higher grade implies worsening conjunctival hypermia

Population: The analysis population consists of all subjects that completed all study visits without a major protocol deviation. The analysis was conducted on subject eyes.

Upper Lid Margin Staining was assessed using Fluorescein Staining and was measured on the Graded Scale is Grade 0: No Staining is present, Grade 1= 1% to 25% Stains, Grade 2= 26% to 50% Stains, Grade 3= 51% to 75% Stains, Grade 4 76% to 100% Stains. The percentage of eyes with upper lid margin staining for each Grade is reported.

PRIMARY outcome

Timeframe: Baseline to 4- Week Follow-up

Population: The analysis population consists of all subjects that completed all study visits without a major protocol deviation. The analysis was conducted on subject eyes.

Corneal staining Area Grade was assessed in throughout five (5) regions in the eye (Central, Nasal, Temporal, Inferior, Superior). Corneal Staining was Graded using the Efron scale from 0 to 4 in 0.1 unit steps and converted to a percentage of region that was stained. The average percent of region that was stained was calculated and reported.
