Lattice corneal dystrophy: Epithelial macroerosions in clear corneal grafts

Two sisters, aged 33 and 35, underwent uncomplicated penetrating keratoplasty for lattice corneal dystrophy type I. Both patients, as well as their younger brother, had experienced frequent recurrent epithelial erosions prior to undergoing corneal grafting. Each sister has subsequently experienced painful, corneal epithelial macroerosions in the corneal graft, in the absence of any signs of recurrence of the lattice corneal dystrophy in the grafted tissue. With treatment each episode of macro-erosion has resolved without complication. To our knowledge, this is the first report of epithelial erosions in a corneal graft without clinical evidence of recurrent lattice corneal dystrophy.
