Late-onset capsular block syndrome: unusually delayed presentation

Capsular block syndrome (CBS) has been known to occur as a rare complication of cataract surgery with continuous curvilinear capsulorhexis and a posterior-chamber lens implant. Typically, it presents with reduced vision in the early postoperative period and is characterised by a forward displacement of the posterior-chamber intra-ocular lens and an accumulation of intra-capsular opaque material. Management of CBS is usually by Nd:YAG laser capsulotomy. In this report, we describe a unique case of very-delayed-onset CBS with good visual acuity, occurring 8 years after surgery. It was treated successfully with surgical removal of the opaque material.
