Primary outcomes

  1. Pre-Lens Non-Invasive Tear Break-Up Time (PL-NITBUT)

    Time frame: Day 7, 16 hours after lens insertion

    The pre-lens tear film is the layer of tears located on top of the contact lens (i.e., between the eye lid and the contact lens). The time required for a dry spot to appear on the corneal surface after blinking is referred to as the tear film break-up time. Circular images were projected onto the corneal surface using a CA-1000 topographer, and the tear film reflection was observed on a 30-inch flat panel monitor. PL-NITBUT was recorded at the first sign of image distortion. Three measurements were taken and averaged together. A higher number represents a longer tear film break up time.
