Trial Outcomes & Findings for Prospective Study of an Investigational Toric Soft Contact Lens (NCT NCT01461811)

NCT ID: NCT01461811

Last Updated: 2013-10-17

Results Overview

Visual acuity, as assessed for each eye individually. Participant read a distance Snellen chart while wearing study lenses. The percentage of eyes with VA recorded as 20/30 or better is reported. Both eyes contributed to the percentage.

Recruitment status

COMPLETED

Study phase

NA

Target enrollment

154 participants

Primary outcome timeframe

Participant Flow

Participants were recruited from ten US study centers.

Of the 154 participants enrolled, ten participants were considered enrolled, but not dispensed, due to not meeting inclusion criteria or withdrawal of consent. This reporting group includes all enrolled and dispensed participants (144).

Lens centration, as assessed by the investigator for each eye individually. Lens centration was graded on a 5-point scale: 0=centered, 1=slight decentration, 2=mild decentration, 3=moderate decentration, 4=severe decentration. The combined percentage of lenses assessed as "centered" or "slight decentration" is reported. Lenses from both eyes contributed to the percentage.
