Die perforierende Keratoplastik - Indikationen unter besonderer Berücksichtigung der Kunstlinsenkeratopathie

Abstract

During the period from 1980 until the beginning of 1986, 1,219 corneal buttons removed in the course of penetrating keratoplasty were histologically examined. In 16.5% (201 cases) a re-keratoplasty was necessary. Indications for a primary corneal transplant (n = 1,018) were keratitis-induced corneal changes (35.0%), dystrophies (30.5%), surgical traumas (17.2%), nonsurgical traumas (11.4%), congenital corneal clouding (3.1%) and degenerations (2.8%). Over the six-and-a-half-year period the incidence of pseudophakic bullous keratopathy was 6.9%, with an increase from 1.6% in 1980 to 12.4% in 1986. Besides an unspecific endothelial cell atrophy, fibroblast-like cell structures, possible macrophages, were found in some specimens by histologic examination on corneal buttons as well as on explanted intraocular lenses.
