Water, electrolyte and free amino acid content of the crystalline lens were estimated in patients with nuclear cataract and in immature, mature and hypermature cortical cataract groups. Wet weight/dry weight and sodium/potassium ratios were calculated. Sodium, potassium ratio was significantly higher in immature cortical cataract when compared with the nuclear cataract. With maturation of the cortical cataract, the lens was found to be more hydrated and there was accumulation of sodium. However, free amino acid content of the lens decreased. A hypothesis has been proposed for alterations in the active transport pump of the crystalline lens during the maturation of the cortical cataract.
