What this trial measures

  • Goldmann Applanation Intraocular PressurePhase 2: 1 hour on 3 days Phase 3: Up to 14 hours on 3 days

    The IOP of participants will be measured with the Goldmann applanation tonometry (GAT) prior to and following device use, and in the contralateral eye during device use. A \>2 mmHg difference in is considered clinically significantly different.

  • I-Care Tonometry Intraocular PressurePhase 2: 1 hour on 3 days Phase 3: Up to 14 hours on 3 days

    The I-Care (I-Care, Inc.) tonometry will also be evaluated during contralateral eye device use. A \>2 mmHg difference in is considered clinically significantly different.

  • Lens comfortPhase 2: 1 hour on 3 days Phase 3: Up to 14 hours on 3 days

    Participant-reported comfort will be assessed using a simple 100-point numeric scale where a rating of '100' represents extremely uncomfortable/intolerable and a rating of '1' perfectly comfortable/not noticeable at all. Comfort assessments will occur prior to, during, and following all device use to allow comparisons to typical or comparator devices. A 7-point difference in ratings is considered clinically significantly different.

  • Lens FitPhase 2: 1 hour on 3 days Phase 3: Up to 14 hours on 3 days

    Lens fit will be measured with slit lamp during lens wear and graded using the Cornea and Contact Lens Research Unit (CCLRU) grading scale, which ranges from 0 to 4 with a rating of 0 representing an optimal outcome. A difference of 1.0 grading unit will be considered clinically significant.
