What is the appropriate treatment for a corneal abrasion?

Treatment for Corneal Abrasion

For simple corneal abrasions, prescribe topical antibiotic prophylaxis (particularly for contact lens wearers and trauma cases), avoid eye patching, and consider topical NSAIDs for pain control—bandage contact lenses remain controversial and should be avoided in contact lens-related abrasions due to infection risk.

Antibiotic Prophylaxis

When to Prescribe Antibiotics

Topical antibiotics should be prescribed to prevent bacterial keratitis in patients with corneal abrasions, especially in high-risk scenarios 1:

• Contact lens wearers with corneal abrasion - this is mandatory due to increased risk of Pseudomonas infection 1
• Any traumatic corneal abrasion - broad-spectrum coverage helps prevent both bacterial and fungal infection 1
• Treatment initiated within 24 hours of injury - prophylaxis has been shown to prevent ulceration when started early 1

Antibiotic Selection

For contact lens-related abrasions, use antipseudomonal coverage 2:

• Fluoroquinolones (ciprofloxacin 0.3%, ofloxacin 0.3%, or levofloxacin 1.5%) are FDA-approved for bacterial keratitis and provide appropriate coverage 1
• Fourth-generation fluoroquinolones (moxifloxacin, gatifloxacin) have better gram-positive coverage but are not FDA-approved for this indication 1

For non-contact lens traumatic abrasions 1:

• Chloramphenicol ointment 1% three times daily for 3 days has demonstrated effectiveness in preventing progression to corneal ulcers 1
• Broad-spectrum topical antibiotics are appropriate alternatives 1

Important Caveats About Antibiotics

The evidence supporting antibiotic prophylaxis is actually quite limited—a 2025 Cochrane review found very low certainty evidence, with one study paradoxically showing antibiotics may increase infection risk compared to vehicle control 3. However, guidelines still recommend antibiotics based on biological plausibility and the serious consequences of bacterial keratitis 1.

What NOT to Do

Avoid Eye Patching

Pressure patching is contraindicated and should not be used 1, 4:

• Does not improve pain control 4
• Does not accelerate healing—actually delays it 4
• Significantly increases risk of bacterial keratitis, especially in contact lens wearers 1
• Patients heal faster and have less pain without patching 4

Bandage Contact Lenses - Use With Extreme Caution

For contact lens-related abrasions, avoid therapeutic contact lenses due to increased risk of secondary bacterial keratitis 1:

• The risk of infectious keratitis is higher when bandage lenses are used in contact lens wearers 1
• If used in other patients, must be combined with antibiotic prophylaxis and close follow-up 1
• Patients must be warned about infection risk and instructed to report immediately if redness, pain, or photophobia develops 1

Pain Management

Topical NSAIDs - First-Line for Pain

Topical NSAIDs provide effective pain control and are the preferred topical analgesic 5:

• Significantly reduce pain scores at 24 hours (SMD -0.69) and 48 hours (SMD -0.56) 5
• Reduce oral analgesic use by 53% compared to control 5
• Do not delay healing or increase complications 5

Topical Anesthetics - Limited Short-Term Use Only

For simple corneal abrasions only, topical anesthetics (proparacaine, tetracaine) may be prescribed for home use under strict conditions 6:

• Maximum 1.5-2 mL total dispensed (24-hour supply) 6
• Use every 30 minutes as needed for first 24 hours only 6
• Any remainder must be discarded after 24 hours 6
• Only for simple abrasions diagnosed according to full protocol—not for complicated cases 6

Common pitfall: Prolonged use of topical anesthetics causes corneal toxicity and delayed healing—this is why the 24-hour limit is critical 6.

Cycloplegics - Not Routinely Indicated

Evidence does not support routine use of topical cycloplegics for uncomplicated corneal abrasions 2. However, they may be considered when substantial anterior chamber inflammation is present 1.

Oral Analgesics

Oral acetaminophen or NSAIDs are reasonable for residual discomfort 1.

Adjunctive Measures

Topical antibiotic ointment (rather than drops) may be used at bedtime for less severe cases, though ointments penetrate poorly 1.

Protective eye shield (hard plastic shield, paper cup, or plastic cup taped over the eye) helps prevent unintentional touching 1.

Follow-Up Strategy

Small uncomplicated abrasions (≤4 mm) with normal vision and resolving symptoms may not require follow-up 2.

All other patients should be re-evaluated in 24 hours 2:

• Worsening symptoms
• Corneal infiltrate or ulcer development
• Significant vision loss
• Larger abrasions (>4 mm)

Immediate ophthalmology referral indicated for 1:

• High-velocity injuries (grinding, nailing, machinery)
• Penetrating eye injury
• Irregular pupil after trauma
• Eye bleeding after trauma
• Loss of vision after trauma
• Persistent foreign body sensation despite treatment

Special Populations

Contact lens wearers: Must receive antipseudomonal antibiotic coverage, avoid patching and therapeutic contact lenses, and be counseled about infection risk and proper lens hygiene 1, 2.

Patients with chronic epithelial defects: Prophylactic antibiotics are controversial due to risk of promoting resistant organisms, though may be considered 1.
