Acellular Nerve Allografts in Corneal Neurotisation: An Inappropriate Choice

What Is This Study About?

This editorial critiques the use of processed cadaveric nerve grafts (acellular nerve allografts) for corneal neurotization, arguing that their limited regenerative capacity makes them suboptimal. The author advocates for autologous nerve grafts for corneal sensory restoration.

Key Findings

• Acellular nerve allografts have limited ability to support regeneration over long distances
• Autologous nerve grafts (patient’s own tissue) provide superior sensory restoration
• Corneal neurotization requires reliable regeneration for effective sensory recovery

What This Means for Patients

Patients considering corneal neurotization should discuss graft options with their surgeon, as the choice of nerve conduit significantly impacts the likelihood of restoring protective corneal sensation.
