Sight-threatening adverse events occurring in the study eye included, but were not limited to: BCVA loss of ≥ 3 lines, endophthalmitis, corneal decompensation, severe retinal detachment, severe choroidal hemorrhage, severe choroidal detachment and aqueous misdirection. The number of events at the end of Year 5 was divided by the number of eyes at risk at the beginning of Year 1 for a 5-year annualized rate. The 5-year annualized rate is reported as a percentage, with the last annual non-censored rate divided by 5. Inferential testing was not planned for this endpoint.

All enrolled subjects with available data

Best corrected (with spectacles or other visual corrective devices) VA was assessed using Early Treatment Diabetic Retinopathy Study (ETDRS) charts at 1 or 4 meters and determined by total number of letters read correctly. 20/20 Snellen is considered 'normal' vision. A larger denominator indicates a lower visual acuity. Baseline, Month 12, and Month 24 data derived from previous COMPASS trial. One eye (study eye) contributed to the analysis. Inferential testing was not planned for this endpoint.

All enrolled subjects with available data

Ocular adverse events in the study eye could include, but were not limited to, BCVA loss of 2 lines (10 letters) or more on the ETDRS chart in comparison with the best BCVA reported in Study Protocol TMI-09-01, endophthalmitis, corneal edema, and corneal decompensation. Inferential testing was not planned for this endpoint.

All enrolled subjects

Corneal Edema (swelling of the cornea) was assessed by the investigator during slit-lamp examination and rated on a 4-point scale: None (transparent and clear or less than mild), Mild (dull glassy appearance), Moderate (Dull glassy appearance of epithelium with large number of vacuoles), and Severe (epithelial bullae and/or stromal edema, localized or diffuse, with or without stromal striae). Only the categories with reported data are included. One eye (study eye) contributed to the analysis. Inferential testing was not planned for this endpoint.

Corneal Staining (appearance of tissue disruption and other pathophysiological changes) and erosion (abrasion) were assessed by the investigator during slit-lamp examination and rated on a 4-point scale: None (no fluorescein staining of epithelium, OR less than mild), Mild (slight fluorescein staining confined to a small focus), Moderate (regionally dense fluorescein staining (1 mm or greater in diameter) with underlying structure moderately visible), and Severe (marked fluorescein staining or epithelial loss). Only the categories with reported data are included. One eye (study eye) contributed to the analysis. Inferential testing was not planned for this endpoint.

Inflammatory anterior chamber cells (cells in the front portion of the eye) were assessed by the investigator during slit-lamp examination and reported in one of 6 categories according to cells per 1x1 mm slit: 0-<1 cell, 1-5 cells, 6-15 cells, 16-25 cells, and 26-50 cells, and >50 cells. Only the categories with reported data are included. One eye (study eye) contributed to the analysis. Inferential testing was not planned for this endpoint.

Anterior Chamber Flare (protein escaping from dilated vessels) was assessed by the investigator during slit-lamp examination and rated on a 5-point scale: None, Faint, Moderate (iris and lens details clear), Marked (iris and lens details hazy), and Intense (fibrin or plastic aqueous). The presence of flare is a sign of intraocular inflammation. Only the categories with reported data are included. One eye (study eye) contributed to the analysis. Inferential testing was not planned for this endpoint.

Iris Atrophy/Erosion (deterioration) was assessed by the investigator during slit-lamp examination and rated on a 4-point scale: None, Mild, Moderate, and Severe. Only the categories with reported data are included. One eye (study eye) contributed to the analysis. Inferential testing was not planned for this endpoint.

All subjects with available data at that visit

Iris Peaking (one part of the iris pulled to a peak resulting in an irregular pupil) was assessed by the investigator during slit-lamp examination and rated on a 4-point scale: None, Mild, Moderate, and Severe. Only the categories with reported data are included. One eye (study eye) contributed to the analysis. Inferential testing was not planned for this endpoint.

All subjects with available data at that visit

Iris Rubeosis (abnormal blood vessels (formed by neovascularization) found on the surface of the iris) was assessed by the investigator during slit-lamp examination and rated on a 4-point scale: None, Mild, Moderate, and Severe. Only the categories with reported data are included. One eye (study eye) contributed to the analysis. Inferential testing was not planned for this endpoint.

All subjects with available data at that visit

PCO (cloudy layer of scar tissue behind the lens implant) Severity was assessed by the investigator during slit-lamp examination and rated on a 6-point scale: None, Minimal, Mild, Moderate, Severe, and Unspecified. Only the categories with reported data are included. One eye (study eye) contributed to the analysis. Inferential testing was not planned for this endpoint.

All subjects with available data at that visit

For subjects in the CyPass group, gonioscopic examination was performed to assess the position of the CyPass Micro-Stent in the angle and with respect to the iris and the corneal endothelium. A visible CyPass Micro-Stent indicated a lack of adhesions (favorable). One eye (study eye) contributed to the analysis. Inferential testing was not planned for this endpoint.

Number of eyes with available data and CyPass not explanted before visit

The dilated fundus examination was performed by the investigator to evaluate the health of the vitreous, retina, macula, choroid, and optic nerve. Clinically significant findings are reported categorically. One eye (study eye) contributed to the analysis. Inferential testing was not planned for this endpoint.

Subjects with available data at each visit

Visual field (how much one can see to each side while focusing the eyes on a central point (peripheral vision)) deviations were obtained with a Humphrey automated perimeter using the 24-2 SITA standard testing method. Normal deviation values are typically within 0 to -2 decibels (dB) and become more negative as the overall field worsens. Month 24 data derived from COMPASS trial. One eye (study eye) contributed to the analysis. Inferential testing was not planned for this endpoint.

All subject eyes for which data was available at the visit

Central corneal thickness was evaluated by Pachymetry and measured in micrometers (μm). A negative number indicates a decrease in corneal thickness (unfavorable). Month 24 data derived from COMPASS trial. One eye (study eye) contributed to the analysis. Inferential testing was not planned for this endpoint.

Subject eyes for which data was available at the visit

The endothelium maintains corneal hydration and reduced cell density can disrupt vision. Central endothelial cell counts were assessed using non-contact specular microscopy. Specular images were taken of the corneal endothelium and submitted to a reading center in order to standardize readings across all sites and optimize reading reliability. Baseline through Month 24 data were derived from COMPASS trial. A higher cell density indicates improvement. One eye (study eye) contributed to the analysis. Inferential testing was not planned for this endpoint.

All subject eyes for which data was available at the visit

Device position was a qualitative and subjective assessment by the investigator and evaluated based on visible number of rings of the device under the gonioscopic exam. One eye (study eye) contributed to the analysis. Inferential testing was not planned for this endpoint. This outcome measure was prespecified for Cataract Surgery + CyPass arm only.

Total number of subjects in the treatment group

IOP (fluid pressure inside the eye) was assessed using Goldmann applanation tonometry and reported in millimeters mercury (mmHg). A higher IOP can be a greater risk factor for developing glaucoma or glaucoma progression (leading to optic nerve damage). A higher reduction from baseline (ie, a greater postitive number) indicates greater improvement. Baseline was derived from COMPASS trial. One eye (study eye) contributed to the analysis. Inferential testing was not planned for this endpoint.
