Corneal scratch recovery time is related to the severity of the patient’s condition. If the scratch is only to the corneal epithelium, it takes about 24 to 48 hours to recover. If the scratch involves the stromal layer, it takes about 3~4 weeks to recover. However, if the scratch causes the patient to have a full corneal laceration, it will take about 3 to 6 months to recover. The length of time it takes to recover from a corneal laceration is influenced by factors such as the depth of the laceration and the presence of localized inflammation. The corneal epithelium can regenerate, and if the scratch only damages the corneal epithelium, it can usually recover on its own in about 24-48 hours. However, the corneal stroma is not regenerative, and if a corneal scratch damages the corneal stroma as well as deeper scratches, it takes longer to recover and may take 3 weeks to 6 months or more. In patients with full corneal lacerations, even if the wound recovers, a corneal scar can form that may cause permanent damage to the patient’s vision. It is recommended that patients with corneal scratches seek prompt medical attention to evaluate their condition and follow medical advice.
