[Use of beta adrenergic blockaders in the prevention of vitreous body prolapse in cataract extraction].

To prevent vitreous body prolapse in cataract extraction, intraocular pressure is reduced by means of beta-adrenoblockers instillation (timolol 0.5% solution) in the evening and 2 hours before surgery in the morning. Intraocular pressure was followed up in 59 patients with senile and 12 with complicated cataract subjected to cataract cryoextraction by the same surgeon. The pressure decreased by 5.6 +/- 1.3 mm Hg. Prolapse of the vitreous body occurred in 1 case.
