A small capsulorhexis makes nucleus removal more difficult, especially when we have a dense cataract. When the entire lens hardens and becomes sclerotic, it will be a challenge to fit parts of the 9 mm wide cataract through a small 4 mm capsulorhexis. In the case shown here, the resident surgeon makes too small of a capsulorhexis. I help by enlarging it from 4 to 5 mm in diameter. While this increases the diameter by 25% (from 4 to 5 mm), it increases the area within the capsulorhexis by 56%!
