Can a cold compress be used for keratitis?

In general, whether patients with keratitis can apply an ice pack depends on the specific condition and medical advice. The details are as follows:

During the acute phase of keratitis, when obvious symptoms such as eye pain, redness, swelling, and photophobia occur, short-term application of an ice pack may be permitted after evaluation by a doctor. Cold compression with an ice pack can constrict blood vessels in the eye area, reduce local congestion and swelling, and help relieve pain and burning sensations. The ice pack should be wrapped in a towel to avoid direct contact with the eyes, and applied for 10–15 minutes per session to prevent frostbite to the surrounding skin.

However, ice packs should not be used during the recovery phase of keratitis, or in cases of viral keratitis or corneal ulcers. During recovery, as ocular inflammation gradually subsides, cold compresses may impair local blood circulation and hinder corneal healing. In cases of viral infection or corneal ulceration, cold compresses may reduce local immunity, potentially worsening the condition or prolonging recovery. Appropriate treatments should be followed strictly as directed by a physician.

Maintain clean and dry eyes; avoid rubbing eyes with dirty hands to prevent bacterial infection. Eat a light diet and consume more foods rich in vitamin A to support corneal repair. Ensure adequate sleep and avoid staying up late or overusing the eyes. Use prescribed anti-inflammatory or antiviral eye drops exactly as directed—do not adjust dosage on your own. If symptoms such as blurred vision or increased pain occur, seek immediate medical attention for re-evaluation.
