Flap motility as a sign of posterior capsule rupture in peripherally extended anterior capsular tears

Figures & data

Figure 1 Posterior capsule barrier and hypothesis of the non-fluttering flap.

Figure 2 Types of capsular tears.

Notes: Type Ia, perpendicular pre-equatorial radial tear; Type Ib, acute-angled pre-equatorial radial tear; Type IIa, perpendicular post-equatorial radial tear; Type IIb, acute-angled post-equatorial radial tear; Type III, Argentinean flag sign pre-equatorial tear; Type IV, Argentinean flag sign post-equatorial tear; Type V, mini punch.

Stage at which tear occurred	Cases (n)	Cases (%)
Capsulorhexis	21	84
Nuclear chopping	1	4
Nuclear division	1	4
Nuclear emulsification	2	8
Total	25	100
