All eyes in both groups received bromfenac ophthalmic solution 0.07% for 2 days prior to surgery and 10 weeks postoperatively.1
OMIDRIA reduces postoperative cme rates
Retrospective analysis was performed on 2218 cataract procedures at a single site.1
OMIDRIA reduces the incidence of CME without the use of steroid drops.1
Retrospective, 2-cohort study (N=2218)1
Continuous delivery of OMIDRIA for consistent therapeutic benefits
Intracameral administration of diluted phenylephrine and ketorolac 1%/0.3% was found to achieve therapeutic levels of ketorolac during surgery in both the aqueous and vitreous humors.3
- With OMIDRIA, ketorolac levels in intraocular structures inhibit COX-1 and COX-2 for at least 10 hours postoperatively, decreasing concentrations of prostaglandins to reduce pain due to surgical trauma3
- Preoperative topical delivery of NSAIDs does not significantly inhibit postoperative levels of COX-1 or COX-23
- Absorption of ketorolac into ocular tissues during surgery and the related inhibition of COX enzymes could potentially have a substantial effect on reducing inflammatory complications, such as CME or retinal thickening3,4
This study was conducted in adherence to the ARVO Statement on the Use of Animals in Ophthalmic and Vision Research. Lens replacement surgery with phacoemulsification was performed in 20 female beagle dogs. A fixed combination of OMIDRIA was diluted 125-fold into the balanced salt solution and delivered intracamerally during the phacoemulsification procedure. Ketorolac concentration was determined by liquid chromatography/mass spectrometry.
