Management of Corneal Abrasion
All corneal abrasions should be treated with broad-spectrum topical antibiotics started within 24 hours to prevent bacterial keratitis, and patching or therapeutic contact lenses should be avoided in contact lens wearers and trauma patients due to increased infection risk. 1
Antibiotic Prophylaxis (Critical)
The 2024 American Academy of Ophthalmology Bacterial Keratitis Preferred Practice Pattern provides clear guidance:
Prescribe topical antibiotics for ALL corneal abrasions in two specific scenarios:
- Contact lens wearers with abrasion
- Any traumatic corneal abrasion
Rationale: Prophylactic antibiotics prevent progression to bacterial keratitis and corneal ulceration when started within 24 hours 1
Antibiotic selection:
What NOT to Do
Do NOT patch the eye or use therapeutic contact lenses in contact lens-associated or traumatic abrasions - this significantly increases the risk of secondary bacterial keratitis 1. This is a strong recommendation from the 2024 guidelines that directly impacts morbidity.
Pain Management
- Topical NSAIDs: Effective for pain control 2, 3
- Oral analgesics: Appropriate for symptom relief 2
- Cycloplegics: May be used for pain relief from ciliary spasm, though evidence for routine use in uncomplicated abrasions is limited 2, 3, 4
- Topical anesthetics: Historically contraindicated for outpatient use due to concerns about epithelial toxicity and corneal melting, though recent evidence suggests short-term use may be considered in select cases 5, 6. However, a 2026 study found increased ED readmission rates with topical anesthetic prescriptions (RR 1.81) 7, supporting traditional ophthalmology concerns about safety.
Follow-up Strategy
Small abrasions (≤4 mm) with uncomplicated course, normal vision, and resolving symptoms: Follow-up may not be necessary 2
All other patients should be re-evaluated in 24 hours 2
Immediate ophthalmology referral indicated for:
- Symptoms that worsen or fail to improve
- Corneal infiltrate or ulcer development
- Significant vision loss
- Any concern for penetrating injury 2
Clinical Pearls
The guidelines emphasize that most simple corneal abrasions heal within 24-48 hours 4. The primary goals are preventing infection (which can cause permanent vision loss), controlling pain, and ensuring appropriate healing. The strong stance against patching in at-risk populations represents a shift from older practices and is based on infection prevention - a morbidity and mortality concern that supersedes theoretical benefits of immobilization.
Key caveat: While some practitioners omit antibiotics when close follow-up is assured 8, the 2024 AAO guidelines clearly recommend antibiotic prophylaxis for contact lens and trauma-related abrasions given the serious consequences of bacterial keratitis progression.
