  Purpose: We categorize weak zonule during capsulorhexis. Design: Retrospective interventional case series. Methods: The study examined 5447 consecutive eyes of 3527 cases that underwent phacoemulsification (PEA) and intraocular lens (IOL) implantation between March 2006 and March 2014 at Showa University Fujigaoka Hospital, Kanagawa, Japan. Weak zonule was categorized based on findings at capsulorhexis and difficulty in performing continuous curvilinear capsulorhexis (CCC). The categorization definitions were as follows: (1) Group N (normal) with no or slight lens movement at the start of the CCC and no difficulty in performing CCC, (2) Group W (weak) with moderate lens movement frequently accompanied by fold formation during CCC and some difficulty in performing CCC, (3) Group VW (very weak) because of severe lens movem..
