Abstract

PURPOSE:

To evaluate the study drug OMS302 (Omidria [phenylephrine and ketorolac injection 1.0%/0.3%]) compared with a balanced salt solution (vehicle), ketorolac, and phenylephrine on pupil diameter during cataract surgery and early postoperative ocular pain.

SETTING:

Twenty-three centers in the United States.

DESIGN:

Randomized clinical trial.

METHODS:

Patients were randomized (1:1:1:1) to receive vehicle, phenylephrine, ketorolac, or the study drug containing phenylephrine and ketorolac administered intracamerally during surgery. Intraoperative pupil diameter was determined each minute by video capture. Postoperative ocular pain was evaluated for up to 12 hours.

RESULTS:

The study evaluated 223 patients. The study drug was significantly better than the vehicle and ketorolac in maintaining mydriasis (least-squares mean differences 0.9 ± 0.1 [SEM] and 0.7 ± 0.1 for the study drug versus vehicle and ketorolac, respectively; P < .0001 each). Ocular pain assessed using the Visual Analog Scale was significantly reduced for the study drug compared with the vehicle or phenylephrine (least-squares mean difference -4.6 ± 2.2 and P = .042 and 5.9 ± 2.2 and P = .009, respectively). Significantly fewer patients treated with the study drug (3 [6.1%]) had an intraoperative pupil diameter smaller than 6.0 mm compared with those treated with the vehicle (25 [47.2%]; P < .0001), ketorolac (18 [34.6%]; P = .0004), or phenylephrine (11 [22.4%]; P = .0216).

CONCLUSIONS:

The study drug was safe and efficacious in maintaining mydriasis and reducing postoperative ocular pain. Both ketorolac and phenylephrine contributed to the therapeutic effects, with the combination showing superiority to either agent alone in maintaining an intraoperative pupil diameter of 6.0 mm or larger.
