[Metipranolol in the prevention of intraocular pressure elevation after cataract extraction].

Elevated intraocular pressure during the first few days after routine intracapsular cataract extraction with and without alpha-chymotrypsin is a well-known symptom. A prospective, double-blind study was conducted to determine whether Metipranolol would prevent this increase in pressure. In 40 eyes which underwent routine, uncomplicated cataract extraction a drop of either Metipranolol 0,6% or placebo was administered before and during the first days after surgery. Prophylactic Metipranolol 0,6% can substantially reduce the incidence of severe early postoperative ocular hypertension.
