Brief Summary:
The objective of this study is to compare the maintenance of intraoperative mydriasis during cataract surgery between two drugs: epinephrine, which has routinely been used for decades, and Omidria, a newly FDA approved combination drug of phenylephrine and ketorolac. Patients undergoing cataract surgery that are enrolled in the trial will randomly receive one of the drugs in one eye, and the other eye will receive the drug during the subsequent cataract surgery.
Detailed Description:
Cataract remains a leading cause of correctable blindness worldwide. Over 3.5 million cataract surgeries in the United States and 20 million cataract surgeries worldwide are performed every year. Cataract surgery is performed by making a small incision, removing the cataractous lens, most often through the process of phacoemulsification, and replacement with an intraocular lens. Like all surgeries, adequate exposure and field of view is vital for a safe and effective surgery. In cataract surgery, the field of view is limited by the diameter of the pupil. Several different drugs, such as cyclopentolate, tropicamide, phenylephrine, and epinephrine are utilized to maintain dilation (mydriasis) of the pupil during surgery.
There are currently two prospective randomized controlled trials comparing phenylephrine/ketorolac to placebo in the published literature. Both of these studies demonstrated that phenylephrine/ketorolac is superior to placebo for the maintenance of mydriasis during cataract surgery. Epinephrine has been the standard of care for intraoperative mydriasis. Phenylephrine/ketorolac (Omidria) is a newly FDA-approved additive for the maintenance of intraoperative mydriasis, but there are currently no published studies comparing epinephrine to phenylephrine/ketorolac for maintenance of mydriasis during cataract surgery.
While both of these drugs have been shown to be superior to placebo for the maintenance of mydriasis, there is a significant cost difference between epinephrine, which has been used for many years, and phenylephrine/ketorolac, which gained FDA approval in 2014. One 4 mL vial of Omidria® is utilized for one cataract surgery, which costs $465.
The primary endpoint to be measured in the study is the mean area under the curve change from baseline in pupil diameter over time to the end of cataract surgery.
Secondary endpoints will be maximum intraoperative pupil constriction, subjects with pupil diameter less than 6.5 mm at any during surgery, subjects with pupil less than 6.0 mm during cortical clean-up, and subjects with greater than 2.5 mm of pupillary constriction at any time during surgery.
