This is a traumatic cataract with an iridodialysis (separation of the iris from it's attachment to the ciliary body) from a blunt injury during childhood. There is an anterior cortical cataract with evidence of capsular compromise and adhesion of the displaced iris to this area. There is also a lens pseudo-coloboma (lessened convexity along the equator) inferotemporally secondary to zonular dehiscence (not shown).
