Meibomian Gland Imaging Primary · 4-Week Follow-up

Meibomian gland imaging was assessed in each each subject eye, at baseline, 4-Week Follow-up (during lens wear) and the the 5-Week Follow-up on subjects' bare eyes. Meibomian gland imaging is expressed interms of area of loss using the following grading scale: Degree 0 ≈ 0%; Degree 1 ≤ 25%; Degree 2 26% - 50%; Degree 3 51% - 75%; Degree 4 ≥ 75%.

Meibomian Gland Expressibility Primary · 4-Week Follow-up

Meibomian glands were assessed in the three regions of each lower eyelid: temporal, central, and nasal. Approximately five glands are expressed per region with each use of the Meibomian Gland Evaluator. Secretions for each of the 5 glands selected within the three regions were graded using the following secretion grading scale: Grade 0 = No Secretion (Includes capped orifices), Grade 1 = Inspissated (semi-solid, toothpaste-like consistency), Grade 2 = Colored/Cloudy Liquid, Grade 3 = Clear Liquid Oil. The total grades for 5 glands per region was calculated for each subject. The total Meibomian

Lid Margin Evaluation: Number of Eyes With Abnormal Biomicroscopy Findings Primary · 4-Week Follow-up

Lid margin evaluation was conducted for upper and lower lids for both left and right eyes. The presence of the following biomicroscopy findings were recorded as No/normal or Yes/abnormal: * Irregularity: Notching of Margin * Vascularity of Lid Margin: Telangiectasia * Meibomian Gland Pouting, Plugging, or Capping * Lid/Lash Margin Debris Findings. The number of positive findings (yes) was reported for each group.

Lid Wiper Epitheliopathy Primary · 4-Week Follow-up

Horizontal length of staining and sagittal width of staining were graded for both upper and lower lids for each eye. Average grade was calculated separately for upper and lower lids, and the final grade was calculated as the average grade across upper and lower lids. Mean and standard deviation were reported for the final grade by stratum. Subjects were classified according to their final lid wiper epitheliopathy grade for each eye using the following scale: None = 0, Mild = 0.25 - 1.00, Moderate = 1.25 - 2.00, and Severe = 2.25 - 3.00. Final Grades range from 0 to 3, where higher final grades

Conjunctival Folds Primary · 4-Week Follow-up

Lid-parallel conjunctival folds (LIPCOF) will be evaluated in the area perpendicular to the temporal and nasal limbus on the bulbar conjunctiva above the lower lid (temporal and nasal LIPCOF, respectively), and classified using the LIPCOF grading scale: 0 = No conjunctival folds, 1 = One permanent and clear parallel fold, 2 = Two permanent and clear parallel folds (normally lower than 0.2mm), and 3 = More than two permanent and clear parallel folds (normally higher than 0.2mm).

Tear Film Lipid Layer Thickness Secondary · 4-Week Follow-up

Tear film lipid layer thickness was measured for each eye using LipiView II. The Review Lipid Images screen provided numerical analysis of the measured lipid layer thickness in nanometers (nm) from 10 (thinnest) to 240 (thickest), with a precision of 1 nm and an accuracy of 10 nm.

Tear Film Stability Secondary · 4-Week Follow-up

Non-invasive tear break-up time (NIBUT) was measured for each eye to indicate the stability of the tear film. NIBUT is measured as the time interval in seconds after the final blink to the first appearance of distortion in the reflected rings; or to the time that the participant has to blink due to discomfort. Three measurements were taken on each eye. The average NIBUT was reported for each group.
