|Official Title:||A Phase 3 Randomized, Double-Masked, Placebo-Controlled Study of the Effect of OMS302 on Intraoperative Pupil Diameter and Early Postoperative Pain in Subjects Undergoing Intraocular Lens Replacement With Phacoemulsification|
- Mean Area-under-the-Curve (AUC) Analysis of Change From Baseline in Pupil Diameter (mm) During Surgery [ Time Frame: from surgery baseline (pre-incision) through surgery end (time of cortical clean-up/wound closure) ]
Change in pupil diameter over time from surgical baseline (immediately prior to surgical incision) to the end of the surgical procedure (wound closure) was summarized using descriptive statistics by treatment arm and time-point (every minute).
The primary analysis of the change in pupil diameter was based on the mean area-under-the-curve (AUC) pupil diameter change from baseline. First, the AUC of the pupil diameter from surgical baseline to wound closure was calculated using the trapezoidal rule. Second, the mean AUC was obtained by dividing the AUC by the total time of surgery. Third, the mean AUC of change from baseline was calculated by subtracting the baseline pupil diameter from the mean AUC.
- Mean Area-under-the-Curve Analysis of Ocular Pain Visual Analog Scale (VAS) Score Within 12 Hours Postoperatively [ Time Frame: 12 hours ]The primary analysis of the ocular pain VAS (where 0 = no pain and 100 = worst possible pain) was based on the mean area-under-the-curve (AUC). The AUC of the ocular pain VAS during 12 hours postoperatively was calculated by the trapezoidal rule in which the hour 11 was used to represent the time-point 10-12 hours. The mean AUC was defined as the AUC divided by the number of hours with ocular pain VAS results during the first 12 hours postoperatively.
- Photophobia at 6 Hours After Surgery (Ocular Pain and Symptoms Numerical Ordinal Scale [Numerical Rating System - NRS] Scores) [ Time Frame: Six hours postoperatively ]Photophobia outcomes based on Ocular Pain and Symptoms Numerical Ordinal Scale (Numerical Rating System - NRS) at 6 hours postoperatively.
- Photophobia at Day 1 After Surgery (Ocular Pain and Symptoms Numerical Ordinal Scale [Numerical Rating System - NRS] Scores) [ Time Frame: One day ]Photophobia outcomes based on Ocular Pain and Symptoms Numerical Ordinal Scale (Numerical Rating System - NRS) at Day 1 postoperatively
- Best Corrected Visual Acuity (BVCA) Log Score on Day 1 [ Time Frame: One day ]Best-Corrected Visual Acuity (BCVA) summarized by the Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity log score. For subjects without a score due to inability to read the ETDRS chart, the log score was imputed as 1.6 for the purpose of treatment comparisons. Subjects without a score because the manifest refraction was not completed were excluded from the analysis.
- Ocular Inflammation in Summed Ocular Inflammation Score (SOIS) Grade on Day 1 [ Time Frame: One day ]
The mean SOIS summarized by treatment arm and time point on Day 1 postoperatively. Ocular inflammation was evaluated by measuring the anterior chamber cell count and flare using a slit lamp biomicroscope. SOIS was calculated by adding the average of subject's anterior chamber cells and flare grades. The minimum SOIS was 0 (indicating absence of inflammation), whereas the maximum SOIS was 8.
Grading was as follows:
Anterior Chamber Cells: Grade None = 0/no cells; Grade Mild = +1/1-5 cells; Grade Moderate = +2/6-15 cells; Grade Severe = +3/16-30 cells; Grade Very Severe = +4/>30 cells.
Anterior Chamber Flare: Grade None = 0/no Tyndall effect; Grade Mild = +1/barely discernable Tyndall effect; Grade Moderate = +2/moderately intense Tyndall beam in anterior chamber; Grade Severe = +3/severely intense Tyndall beam; Grade Very Severe = +4/very severely intense Tyndall beam with a white and milky appearance to the aqueous
- Ocular Pain VAS Score After Day of Surgery - Day 1 [ Time Frame: One day ]Pain VAS scores (where 0 = no pain and 100 = worst possible pain) after the day of surgery summarized by treatment arm and time-point.

OMS302 diluted in Balanced Salt Solution and administered as irrigation solution during Intraocular Lens Replacement surgery.
OMS302 drug product will be supplied as a sterile, clear colorless liquid, free from particulates of foreign matter. Each vial contains a nominal 4.5 mL solution containing 60.75 millimolar (mM) phenylephrine hydrochloride (HCl) and 11.25 mM ketorolac tromethamine formulated in a 20 mM sodium citrate buffer (pH 6.3 +/- 0.5). For administration to patients, 4.4 mL of the drug product is added to a 500 mL bottle of commercially available balanced salt solution (BSS) through a syringe filter. This will achieve 4.0 mL of the drug product in a 500 mL bottle of BSS.
