It was evaluated whether ArF 193 nm excimer laser corneal surgery represents a risk factor in cataractogenesis. For this purpose, 20 male albino rabbits underwent a photorefractive keratectomy and biochemical analyses on aqueous humour (hydrogen peroxide, ascorbic acid, and reduced and oxidized glutathione) and on lens (malondialdehyde, reduced and oxidized(More)
Twenty male albino rabbits were studied. Four animals served as controls; the remaining 16 animals represented the treated group. All the treated animals were exposed to the same amount of energy delivered by the excimer laser (pulse rate: 20 Hz, fluence 250mJ/cm2; number of pulses: 6032; cumulative UV dose 1508 J/cm2) and were divided into eight groups of(More)

The activity of galactokinase in red blood cells, has been assayed in 17 patients with idiopathic senile and presenile cataract and in 12 age-matched subjects with perfectly transparent lenses. 3 of the idiopathic cataract patients (17.6%) showed low erythrocytes GK activity, while nobody in the control group showed reduced GK activity. Although(More)
The activity of galactokinase in red blood cells of 30 patients affected by idiophatic presenile and senile cataract, and of 20 age-matched controls with perfectly transparent lenses, was investigated. The results obtained show a partial deficiency of the galactokinase activity in the patients affected by presenile idiopathic cataract. There is, moreover, a(More)
