Clinical outcomes of corneal neurotization using sural nerve graft in neurotrophic keratopathy
Fig 2
Surgical steps of corneal neurotization.
(A) Identification and exposure of sural nerve, (B) Desired length of 10-12cm of the sural nerve was traced distally. (C) Careful fascicle separation through the epineurium window at the distal end. (D) Donor supra-trochlear nerve identification, (E) Reverse sural nerve tunnelling across the nasal bridge and (F) courses through sub-brow blepharotomy incision. (G) Fine segregation and recognition of separated fascicles under a microscope. (H) Secure individual fascicle sub-conjunctively at the perilimbal region, (I) End-to-side Coaptation of donor supra-trochlear nerve to inter-positional sural nerve graft.
