[Corneal neurotization].

The previous treatment options for neurotrophic keratopathy (NK) were limited. Frequently performed surgical procedures for severe NK include amnionic membrane transplantation and tarsorrhaphy. Corneal neurotization describes the transposition of a healthy donor nerve along the limbal circumference to re-establish corneal sensation and trophic function. The nerve transfer can be performed either by directly transpositioning the supraorbital nerve as described here or by using a sural nerve interponate.
