PRIMARY outcome
Timeframe: 45 minutes post lens applicationEach study eye (one eye from each participant) was evaluated to determine if the lens was "Centered" (yes) or "Decentered" (no) on the eye after 45 minutes of wear. Outcome measure reports data only from the study eye. All participants were reported in this outcome measure.

PRIMARY outcome
Timeframe: 45 minutes post lens applicationEach study eye (one eye from each participant) was evaluated to determine if the scleral landing zone was properly aligned on the eye (yes) or not properly aligned on the eye (no) after 45 minutes of wear. Outcome measure reports data only from the study eye. All participants were reported in this outcome measure.

SECONDARY outcome
Timeframe: 45 minutes post lens applicationLens rotation after 45 minutes of wear. Lens rotation was measured using an embedded program in the iTRACE system. The rotation data with image guided fitting with the OCT system was collected to compare with known experience with non-image guided fitting sets (the traditional fitting process), which typically rotate approximately 20-30 degrees on the eye. A lower number may indicate the manufactured lens more closely approximates the contours of the eye. Outcome measure reports data only from the study eye.

SECONDARY outcome
Timeframe: 45 minutes post lens applicationNumber of participants achieving an acceptable fitting lens after 45 minutes of lens wear. All participants are reported. Outcome measure reports data only from the study eye. Is the fit acceptable for dispensing to the patient (yes) or is the fit NOT acceptable for dispensing to patient (no) as evaluated 45 minutes post lens application.

SECONDARY outcome
Timeframe: 45 minutesNumber of patients with lens movement after 45 minutes of wear are reported. Lens movement (YES) means the lens is NOT appropriately fitting/settling on the eye. Lens movement (NO) means the lens is appropriately fitting/settling on eye. Outcome measure reports data only from the study eye.
