What Are Corneal Injuries?
A clear, healthy cornea—the protective outer layer of the eye—is essential to good vision. Occasionally, the cornea can get scratched or punctured in an accident, or it can develop a corneal ulcer (open sore).
Injuries to the cornea can result in edema, or swelling, which can cause additional discomfort and blurred vision.
Minor scratches and irritations usually heal within a day or two. You may need prescription antibiotic eye drops to prevent infection. Serious eye injuries should be seen in the emergency room as soon as possible.
