How long it takes to recover from corneal injury is related to the severity of the injury and cannot be generalized. Some corneal injuries can recover gradually and the recovery time depends mainly on the severity of the injury. Minor corneal scratches can be fully repaired within 24-48 hours; corneal injuries involving the corneal stroma, as well as more severe corneal lacerations, may take 1-3 months to gradually repair. If the cornea is fully lacerated, surgical treatment is required, and it takes about 3-6 months to fully recover after surgical repair, which can result in scarring and possibly blurred vision. In addition, patients should pay attention to eye hygiene after corneal injury, use antibiotic drops to prevent infection, and use recombinant bovine basic fibroblast growth factor eye drops to promote recovery from corneal injury.
