Final answer:
The most probable cause of the red eye and swelling after cataract surgery is inflammation. Cataracts are a clouding of the lens of the eye, and surgery involves removing the cloudy lens and replacing it with an artificial lens. It is important for the patient to follow their doctor's instructions for post-operative care.
Step-by-step explanation:
The most probable cause of the red eye and swelling after cataract surgery is inflammation. Inflammation is a natural response of the body to surgery and can cause redness, swelling, and discomfort. This inflammation usually resolves on its own with time and appropriate post-operative care.
Cataracts are a clouding of the lens of the eye, which can cause blurry vision, the need for brighter light, and faded colors. The surgery involves removing the cloudy lens and replacing it with an artificial lens. While cataract surgery is generally safe and effective, complications can occur, including inflammation, infection, and increased eye pressure.
It is important for the patient to follow their doctor's instructions for post-operative care, including using prescribed eye drops, avoiding strenuous activities, and protecting the eye from irritants or trauma. If the redness and swelling persist or worsen, it is important to contact the doctor for further evaluation and treatment.
