Introduction

Swelling after cataract surgery can be relieved by following instructions for anti-inflammatory medications, applying cold compresses to reduce swelling, controlling intraocular pressure, avoiding strenuous activities, and adjusting diet. It is usually a normal response during postoperative tissue healing. However, if the swelling persists for more than two weeks or worsens, or is accompanied by eye pain, blurred vision, or abnormal discharge, prompt medical attention is recommended.

Swelling after cataract surgery can be alleviated by following prescribed anti-inflammatory medications, applying cold compresses to reduce swelling, controlling intraocular pressure, avoiding strenuous activities, and adjusting dietary habits. This swelling is usually a normal part of the postoperative tissue healing process. However, if swelling persists beyond two weeks or worsens, or if accompanied by eye pain, blurred vision, or abnormal discharge, prompt medical attention is recommended.

1. Use prescribed anti-inflammatory medications: Follow your doctor's instructions to use corticosteroid eye drops, non-steroidal anti-inflammatory drugs (NSAIDs), etc., to suppress ocular inflammation, reduce fluid leakage from tissues, and thereby alleviate swelling at its source. Do not adjust the dosage or discontinue medication without medical advice.

2. Cold compress to reduce swelling: Within the first 48 hours after surgery, apply a cold pack wrapped in sterile gauze to the eye area for 15–20 minutes per session, 2–3 times daily. This helps constrict local blood vessels, reducing congestion and swelling. Avoid direct contact between the ice pack and the eyeball.

3. Control intraocular pressure: Swelling may be associated with elevated eye pressure. Follow your doctor’s instructions for using pressure-lowering medications. Avoid prolonged bending over or keeping your head down to prevent fluctuations in eye pressure that could worsen swelling. Regularly monitor changes in intraocular pressure.

4. Avoid strenuous activities: For one month after surgery, avoid vigorous exercises such as running, jumping, or lifting heavy objects, which can increase eye vibration and accelerate blood circulation, potentially worsening swelling. Daily activities should be gentle and steady.

5. Adjust diet: Eat more foods rich in vitamin C and protein to support eye tissue repair. Avoid high-salt and spicy foods to minimize water and sodium retention in the body, which can help reduce eye swelling.

Ensure adequate sleep after surgery, avoid staying up late and overusing your eyes. Keep the eye area clean and dry. Wear protective eyewear when going outdoors. Attend regular follow-up appointments as instructed to monitor resolution of swelling and overall eye recovery.

At what age can cataract surgery be performed?

There is no absolute age limit for cataract surgery. Individuals ranging from children to the elderly can undergo the procedure as long as their ocular conditions permit and their overall health status can tolerate surgery. The most common patients in clinical practice are aged between 60 and 80 years, with the key factors being the severity of the cataract and the patient's physical tolerance. If vision deterioration affects daily activities or eye discomfort occurs, timely medical evaluation is recommended.

What to do about foreign body sensation after cataract surgery

A foreign body sensation after cataract surgery can be relieved by using artificial tears, avoiding eye rubbing and irritation, maintaining good ocular hygiene, reducing eye strain, and minimizing exposure to environmental irritants. This is usually a normal postoperative response. However, if the sensation persists for more than one week or worsens, or if it is accompanied by pain, sudden vision loss, or increased discharge, prompt medical attention is recommended.
