A simple technique for removal of recurring granular dystrophy in corneal grafts

A 63-year-old man and his 24-year-old son developed recurrences of granular dystrophy in their three corneal grafts within three years after surgery. We regrafted one of the son's corneas. Histologic examination of the corneal button removed during surgery showed an avascular connective tissue layer with the histochemical characteristics of granular dystrophy interposed between the epithelium and Bowman's layer. In the remaining two corneal grafts, we fixed the globe with corneal forceps and removed the opaque dystrophic layer by separating it from the cornea with a spatula. Postoperatively, all three corneal grafts were once more transparent.
