Because cryoextraction is a technique of cataract surgery that is still on trial, it is important that those who are testing the method should put their experiences on record. For that reason, we are publishing the account of 100 consecutive extractions performed by this technique, by the residents in ophthalmology on the ophthalmologic service of Louisiana State University School of Medicine at Charity Hospital of Louisiana at New Orleans, with an instrument devised by one of us (D.L.) for this purpose.
A new epoch in cataract extraction—for so we believe it to be—began in 1961, when Krwawicz1 described the simple, functional instrument he had devised for cryoextraction of cataracts. His extractor was a pencilshaped, nickel-plated copper instrument, which was cooled in a mixture of solidified carbon dioxide (Dry Ice) and methyl alcohol at -79 C. With it, he had been able to perform intracapsular extraction of 48 of 50
