Basic biochemical parameters of one hundred cataractous lenses from Egyptian patients.

Cataractous lenses from an extended population of 100 Egyptian patients whose age, sex and case history had been recorded, were collected and classified morphologically. After determination of the lens wet weights, lenses were microsectioned and basic parameters such as wet weight, dry weight, water content and contents of water-soluble and water-insoluble crystallins of the samples were determined. The data obtained document moderate as well as drastic changes of the investigated parameters along with aging and cataractogenesis, and extend our knowledge from small numbers of hitherto investigated human lenses to a considerably high number of cases.
