Summary: Corneal aging is a process which consists of morphological, topographical and biomechanical changes. Age-related degenerations are: limbal girdle of Vogt, arcus senilis, crocodile shagreen, cornea farinata, amyloid degeneration, sulcus senilis and cornea guttata. Scanning laser confocal microscopy enables an evaluation of age related alterations in subbasal plexus, in keratocyte layer and in a number of endothelial cells. Involutional changes are also known in topographical analysis, which has an important meaning for description of long term results in refractive and cataract surgery. In assessing the biomechanics of the cornea it was investigated that corneal histeresis and corneal resistance factor decrease with age. In elder patients a susceptibility for corneal infections increases due to tear film alterations, slowdown of epithelial renewal and decreased sensitivity. One should remember that older patients need a special ophthalmological treatment considering all aspects of aging of the eye.
