Can you apply warm compresses after cataract surgery?

Warm compresses should be avoided in the early period after cataract surgery. Whether mild warm compresses can be applied during the first 1–2 weeks of recovery must be determined according to medical advice. Early application of heat may worsen ocular congestion and swelling, impair wound healing, while appropriate warm compresses during the recovery phase may help relieve eye discomfort. If persistent eye pain, redness and swelling, or sudden vision loss occur after surgery, prompt medical attention is recommended.

Cataract surgery creates a small incision in the cornea or sclera, and the eye is in a stage of inflammatory response and wound healing during the early postoperative period. Applying heat can dilate blood vessels in the eye, leading to increased congestion and edema, as well as a higher risk of bleeding from the wound, thereby interfering with the healing process. Therefore, warm compresses are generally prohibited within the first week after surgery.

If wound healing progresses well without significant congestion or swelling during the 1–2 week recovery period, and if symptoms such as dryness or stiffness in the eye are present, mild warm compresses may be applied under a doctor’s guidance. Gentle warm compresses can improve local blood circulation, relieve muscle tension, and reduce dryness. However, temperature and duration must be carefully controlled to avoid thermal injury to ocular tissues.

After surgery, maintain eye cleanliness and prevent contaminated water from entering the eye; use prescribed anti-inflammatory eye drops as directed; avoid prolonged eye use and strenuous physical activity; when applying warm compresses, use a towel heated to around 40°C, apply for 10–15 minutes per session, and keep an appropriate distance from the eye.
