What is the best treatment option for a patient with a corneal abrasion, presenting with eye pain, redness, and blurry vision, after a foreign body entered their eye, and who wears contact lenses regularly?

Treatment of Contact Lens-Related Corneal Abrasion

For this contact lens wearer with a corneal abrasion, ciprofloxacin ophthalmic solution is the best treatment option, as fluoroquinolones provide the necessary antipseudomonal coverage required for contact lens-related injuries. 1, 2

Why Ciprofloxacin is the Correct Choice

Contact Lens Wearers Require Antipseudomonal Coverage

• Contact lens-related corneal abrasions carry a significantly higher risk of Pseudomonas aeruginosa infection, which can rapidly progress to sight-threatening bacterial keratitis 2, 3
• Fluoroquinolones like ciprofloxacin are FDA-approved for bacterial keratitis treatment and provide the broad-spectrum coverage needed, particularly against Pseudomonas 1, 4, 5
• The American Academy of Ophthalmology specifically recommends topical antibiotics with antipseudomonal activity for contact lens-related abrasions 2, 4

Dosing Regimen

• For corneal abrasions in contact lens wearers, apply ciprofloxacin drops every 2-4 hours while awake for the first 2 days, then four times daily until healed 2, 5
• More aggressive treatment with frequent antibiotic drops is recommended for contact lens-related cases compared to simple abrasions 2, 4

Why the Other Options Are Incorrect

Topical Anesthetics - NEVER for Treatment

• Topical anesthetics like tetracaine are diagnostic tools only and should never be prescribed for home use 1, 2
• They delay epithelial healing, increase risk of corneal ulceration, and can cause severe corneal toxicity with repeated use 1, 6
• While tetracaine provided temporary pain relief during examination, it has no role in ongoing management 6, 3

Polytrim (Polymyxin B-Trimethoprim) - Inadequate Coverage

• Polytrim lacks adequate antipseudomonal coverage, making it inappropriate for contact lens-related abrasions 2, 3
• While it may be acceptable for simple non-contact lens abrasions, this patient's contact lens use mandates fluoroquinolone therapy 1, 2

Eye Patching - Contraindicated

• Eye patching is absolutely contraindicated in contact lens wearers due to increased risk of bacterial keratitis 1, 2, 4
• Multiple studies demonstrate that patching does not improve pain or healing, and may actually hinder recovery 1, 6, 3
• The American Academy of Ophthalmology explicitly recommends against patching for corneal abrasions 1, 2

Additional Management Considerations

Pain Control

• Oral NSAIDs (ibuprofen) or acetaminophen are appropriate for pain management 7, 2, 4
• Avoid prescribing topical anesthetics for home use despite their effectiveness during examination 1, 2

Contact Lens Precautions

• The patient must discontinue contact lens wear immediately and not resume until complete healing is confirmed by examination 7, 2, 4
• Contact lens use with an active abrasion dramatically increases infection risk 2, 3

Follow-Up Requirements

• Re-evaluate within 24 hours to assess healing and rule out infection 2, 3
• Warning signs requiring immediate return include: increasing pain, purulent discharge, worsening vision, or development of corneal infiltrate 1, 2

Critical Pitfall to Avoid

• Do not use therapeutic bandage contact lenses in contact lens wearers with abrasions, as this further increases bacterial keratitis risk 2, 4
• The patient should be educated that even mild worsening of symptoms warrants immediate ophthalmologic evaluation 2, 4
