PURPOSE: A case of asymptomatic corneal foreign body injury during orthokeratology lens wear is reported. CASE REPORT: An 8-year-old Chinese female myopic child with 21 months of overnight orthokeratology lens wear experienced a corneal foreign body injury without symptoms. The foreign body was removed and the eye treated with prophylactic antibiotic and ocular lubricant. Orthokeratology treatment was resumed 4 weeks after initial detection and management and a small residual corneal scar remained. DISCUSSION: The mechanisms, differential diagnoses, management and role of neural sensitivity in corneal foreign body injury during orthokeratology lens wear are discussed. Clinicians should be aware that subtle corneal insult may be without symptoms during prolonged overnight orthokeratology lens wear.
