Corneal buttons submitted to the Estelle Doheny Eye Foundation from 1947
through 1978 were studied. According to a study of 710 corneal specimens
processed during 31 years, the leading indications for penetrating
keratoplasty were aphakic bullous keratopathy, regrafts, keratoconus, and
Fuchs' endothelial dystrophy. Intraocular lenses were associated with 22%
of all specimens of aphakic bullous keratopathy in 1974, increasing to 68%
of all aphakic bullous keratopathy corneas in 1978. Histopathologic
appearance of aphakic bullous keratopathy corneas with or without an
intraocular lens was similar.
