Abstract
The stretching capacity of continuous circular capsulorhexis (CCC) in 20 human cadaver eyes was determined. The increases in circumference of the tear opening ranged from 164. 5% to 190.9% and that in area of the opening ranged from 235.2% to 364.6%. If a proper technique of capsulorhexis is adopted, the nucleus of 7-9.5 mm in diameter and 3-4.5mm in thickness can be delivered through a CCC opening of 4-6mm in diameter by hydrodissection and hydroexpression of nucleus without capsular tear.
