How Does Ketorolac Ophthalmic Work?

Ketorolac inhibits cyclooxygenase activity and reduces prostaglandin synthesis. Lower prostaglandin activity reduces inflammation and pain in treated ocular tissues.

Who Is Treated With Ketorolac Ophthalmic?

Ketorolac ophthalmic 0.5 percent is used for seasonal allergic eye itching and postoperative inflammation after cataract extraction. Ketorolac ophthalmic 0.4 percent is used for pain and burning or stinging after corneal refractive surgery. Hypersensitivity to a formulation ingredient is a contraindication.

How Is Ketorolac Ophthalmic Dosed?

For seasonal allergic itching, the 0.5 percent drops are used as one drop in the affected eye or eyes four times daily. After cataract surgery, one drop is used four times daily beginning 24 hours after surgery and continuing through the first two postoperative weeks. The 0.4 percent drops use one drop in the operated eye four times daily as needed for up to four days after corneal refractive surgery.

What Serious Risks Are Linked to Ketorolac Ophthalmic?

Topical ketorolac can delay healing and increase ocular bleeding. Serious corneal reactions include keratitis, epithelial breakdown, thinning, erosion, ulceration, and perforation, which can threaten vision. Cross-sensitivity can occur in patients with reactions to aspirin or other nonsteroidal anti-inflammatory drugs. Contact lenses are removed before administration.
