Which medication is used to prevent infection during healing in RCE/EBMD treatment?

• A. Moxifloxacin 0.5% qid x1 week
• B. Prednisolone Acetate 1% qid x1 week
• C. Ketorolac 0.5% qid
• D. Sodium chloride 5% solution

Answer: (A)

During healing of recurrent corneal erosion or EBMD, the corneal surface is vulnerable to infection as the epithelium regenerates. A topical antibiotic is used to prevent microbial keratitis in this healing window. Moxifloxacin 0.5% given four times daily for about a week provides broad-spectrum coverage against common ocular pathogens and penetrates the cornea well, helping prevent infection while the epithelium repairs. The other options do not provide infection prophylaxis: a corticosteroid reduces inflammation but can delay healing and raise infection risk; an NSAID addresses pain and inflammation but doesn’t prevent infection; a saline solution lubricates but has no antimicrobial effect.
