Optho: TINY scratch cornea wind blew hair. Optometrist rx'd drops sulfa base. Allergic to sulfa. Pharm concerned. Opto said use moisturizing drops, probably heal naturally. Minor Discomfort. Thoughts?

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