Y56.5: Ophthalmological drugs and preparations

Ophthalmological drugs and preparations refer to medications specifically designed to treat various conditions associated with the eyes. These can include eye drops, gels, ointments, or medications taken orally or injected. While generally safe, reactions to these medications or their improper use can sometimes cause adverse effects. These effects can range from mild symptoms like irritation, itching, redness, or burning sensation in the eyes, to more severe symptoms such as changes in vision, eye pain or swelling. In some cases, systemic side effects might also occur due to the absorption of medication into the bloodstream, potentially affecting other parts of the body. The reactions can occur immediately after application, or build up gradually over time.
