However, the efficacy of the method was firmly established by him² in 1963 when he reported the results on over 600 cases of all types of cataracts with less than 3% of ruptures of the capsule despite the fact that over 400 cases were of intumescent cataract. He noted the probability of a too-narrow corneoscleral section as a major cause of capsule rupture as well as suggesting capsular shrinkage produced by the freezing as an etiological factor.
