This protocol addresses patients with a corneal foreign body where the mechanism of injury involves contact lens wear, vegetable or organic plant matter, or fingernails — and where initial management has not produced the expected clinical improvement.
The first-line approach for this mechanism is expected to resolve symptoms within a defined timeframe. Escalation to this protocol is triggered when that outcome is not reached.
Removal of the corneal foreign body at a slit lamp, followed by antibiotic prophylaxis with topical fluoroquinolone drops and ointment — with additional management as needed for pain and traumatic iritis.
Improvement of symptoms at the 24-hour follow-up. Corneal abrasion from this mechanism is typically expected to heal within 2 to 3 days.
When the expected improvement does not occur — or when the clinical picture includes difficult circumstances, signs of penetrating eye injury, corneal ulcer, recurrent erosion syndrome, or a sight-threatening infection — the structured protocol identifies the appropriate specialist pathway. The full protocol details the referral criteria and next management step.

Follow-up in 24 hours. If no improvement, then refer to Ophthalmology
Referral to an ophthalmologist is recommended in difficult cases or if the patient has signs and symptoms of a penetrating eye injury, corneal ulcer, recurrent erosion syndrome, a sight-threatening infection, or if the symptoms fail to improve after initial treatment.
If the mechanism of injury to the cornea involves contact lens wear, fingernails, or vegetable/organic plant matter, antibiotic prophylaxis should be provided with topical fluoroquinolone drops (eg, ofloxacin or moxifloxacin) at least 4 times a day, and typically a fluoroquinolone ointment (eg, ciprofloxacin) at night time to provide coverage against gram-negative organisms.
