Only a few authors report on epithelial cysts after PK,45 while the majority of the presented patients in the literature suffer from diffuse epithelial downgrowth.167 We present three patients with cystic epithelial growth in the anterior chamber 1–10 years after primary PK and histopathological findings after complete removal of the cyst.


All three patients were referred to our department with cystic epithelial growth into the anterior chamber. Primary PK was carried out elsewhere. Block excision and corneoscleral grafting were performed by one of us (GOHN) in all three patients. Technical aspects of block excision have been described in detail earlier.28-10
