A: Representative case #5. One month after the therapeutic penetrating keratoplasty using cryopreserved tissue, slit-lamp microscopy revealed marked stromal edema and epithelial bullae coupled with corneal cloudiness of the graft and significant conjunctival hyperemia. B: Representative case #5. Three months after the therapeutic penetrating keratoplasty using cryopreserved tissue, the corneal graft had become almost clear with only mild edema in the stroma. Linear pigmented keratic precipitates on the posterior surface of the cornea can be clearly identified. The conjunctival hyperemia had also nearly resolved. C: Representative case #5. Eleven months after the therapeutic penetrating keratoplasty using cryopreserved tissue, the corneal graft became completely clear with no signs of inflammation, except for localized regional scarring around the graft-host junction
