Corneal abrasion: If he abrasion is not infected it should spontaneously heal within a few days.

Don't use sulfa: If you are allergic to sulfa you should not use it. If the discomfort is minimal or mild it may be OK to just use moisturizing drops. Most cornea abrasions heal within 24 hours as the cornea is the most rapidly healing tissue in the body. There is always a concern for infection hence ordering antibiotics but others are avaialble instead of sulfa if needed. Ask you eye doctor.
