[Long-acting local anesthetics - an enrichment in ophthalmosurgery? (author's transl)].

In 300 cases the effectiveness of the long-acting anesthetic Meaverin-ultra for retrobulbar anesthesia was systematically investigated. The duration of analgesis and immobilisation for the globe as well as for the eyelids runs over hours; they are considerabley more effective than with other common local anesthetics so far. 91% of the patients got free of pains for more than 24 hours after the operation. As to the interruption of pain attacks in cases of haemorrhagic glaucoma painless intervalls of more than 30 hours were reached. Special advantages result in cases of buckling operations for retinal detachment, which have to be followed by photo-(xenon)-coagulation. On the whole, long-acting anesthetics are an extraordinary gain for ophthalmosurgery.
