Omidria ® is added to an ocular irrigating solution used during cataract surgery or intraocular lens replacement and is indicated for maintaining pupil size by preventing intraoperative miosis and reducing postoperative ocular pain. OMIDRIA is an alpha 1-adrenergic receptor agonist and nonselective cyclooxygenase inhibitor indicated for: Maintaining pupil size by preventing intraoperative miosis ( 1 ) Reducing postoperative pain ( 1 ) OMIDRIA is added to an ocular irrigating solution used during cataract surgery or intraocular lens replacement.

Omidria must be diluted prior to intraocular use. For administration to patients undergoing cataract surgery or intraocular lens replacement, 4 mL of Omidria is diluted in 500 mL of ocular irrigating solution. Irrigation solution is to be used as needed for the surgical procedure for a single patient. The storage period for the diluted product is not more than 4 hours at room temperature or 24 hours under refrigerated conditions. Do not use if the solution is cloudy or if it contains particulate matter. Each vial of OMIDRIA must be diluted prior to use for administration to a single patient undergoing cataract surgery or intraocular lens replacement. Dilute 4 mL of OMIDRIA in 500 mL of ocular irrigating solution. Irrigation solution is to be used as needed for the surgical procedure. ( 2 )

Omidria is contraindicated in patients with a known hypersensitivity to any of its ingredients. Hypersensitivity to any component of this product ( 4 )

The most common reported adverse reactions (≥2%) are eye irritation, posterior capsule opacification, increased intraocular pressure, and anterior chamber inflammation.
