How should eye pain from a corneal abrasion be treated?

Eye Pain Treatment for Corneal Abrasion

For eye pain from corneal abrasion, use topical NSAIDs (such as diclofenac) as first-line treatment, combined with oral acetaminophen or NSAIDs if needed, and avoid eye patching. 1

Immediate First Aid Measures

Before definitive treatment, protect the injured eye:

• Do not rub the eye 2
• Remove contact lenses immediately if present and discontinue use 2
• Tape a hard plastic eye shield, paper cup, or plastic cup over the eye to prevent unintentional touching 2
• For low-energy foreign bodies (dust, eyelash), irrigate with tap water or commercial eye wash solution 2

Pain Management Algorithm

First-Line: Topical NSAIDs

Topical NSAIDs (e.g., diclofenac) are the most effective pain treatment based on the strongest evidence:

• Significantly reduce pain scores at 24 hours (standardized mean difference -0.69) and 48 hours (SMD -0.56) 1
• Reduce oral analgesic use by 53% compared to control 1
• Do not delay healing or increase complications 1, 3
• Safe and effective for uncomplicated corneal abrasions 4

Adjunctive Oral Analgesia

• Add oral acetaminophen or NSAIDs for residual discomfort 2
• Particularly useful when topical NSAIDs alone are insufficient

What NOT to Use

Avoid these interventions - they lack efficacy:

• Eye patching: Does not reduce pain and may delay healing 1, 5, 4
• Topical anesthetics for home use: Recent 2026 data shows 81% increased ED readmission rates (RR 1.81) when prescribed 6. While some older studies explored their use, the safety concerns and readmission risk make them inappropriate for outpatient management
• Cycloplegics: No significant improvement in pain control or healing 1, 3, 5

Antibiotic Prophylaxis

While evidence for infection prevention is very low certainty 7, topical antibiotics are commonly prescribed:

• Standard abrasions: Consider topical antibiotic (e.g., erythromycin ointment) though evidence is limited 5
• Contact lens-related abrasions: Use antipseudomonal antibiotics (e.g., fluoroquinolone) due to higher infection risk 5

When to Seek Immediate Medical Attention

Refer immediately if any of these red flags are present 2:

• High-velocity injury (grinding, nailing, machinery)
• Penetrating injury from sharp or metal object
• Irregular pupil after trauma
• Eye bleeding after trauma
• Loss of vision after trauma
• Persistent foreign-body sensation despite irrigation
• Contact lens-related injury

Follow-Up Strategy

• Small abrasions (≤4 mm) with normal vision and resolving symptoms: Follow-up may not be necessary 5
• All other patients: Re-evaluate in 24 hours 5
• Ophthalmology follow-up within 30 days reduces ED readmission risk (RR 0.82) 6

Key Clinical Pitfalls to Avoid

1. Do not prescribe topical anesthetics for home use - associated with nearly doubled readmission rates and epithelial toxicity concerns 6
2. Do not patch the eye - this outdated practice provides no benefit and may harm 1, 5
3. Do not miss contact lens-related abrasions - these require antipseudomonal coverage 5
4. Do not discharge without examining for embedded foreign bodies - these require professional removal 2

Practical Treatment Protocol

For an uncomplicated traumatic corneal abrasion:

1. Irrigate eye if foreign body suspected
2. Apply topical NSAID drops (e.g., diclofenac 0.1%)
3. Prescribe oral acetaminophen or ibuprofen
4. Consider topical antibiotic ointment (erythromycin or fluoroquinolone if contact lens-related)
5. Provide eye shield for protection
6. Arrange 24-hour follow-up for larger abrasions or concerning features
7. Instruct patient on red flag symptoms requiring immediate return
