Ilevro operates through its active ingredient, nepafenac, which penetrates the cornea to reach intraocular tissues and inhibits the cyclooxygenase (COX) enzymes. This inhibition reduces the production of prostaglandins, substances known to cause inflammation and pain in the body, easing post-surgical symptoms such as swelling, pain, and redness. The unique formulation of Ilevro allows for efficient absorption into the eye, ensuring effective relief and recovery following cataract surgery.
