Capsular block syndrome (CBS) first described by Davison in 1989 is defined by a postoperative or intraoperative complication after continuous curvilinear capsulorhexis (CCC) with accumulation of fluid (Viscoelasticum Healon5) between the capsular bag and the intraocular lens. A classification of Miyake et al. divides the CBS into intraoperative, early-postoperative, and late postoperative appearance.

Etiology

The groups of the classification by Miyake et al. differ according to their pathogenesis, but they all show the same aspect of an accumulated liquefied substance within a closed chamber. The mentioned substance emerges when the nucleus of the intraocular lens or its optic occludes the anterior capsule opening created by the CCC method.

An intraoperative CBS may result from the shift of capsulorhexis due to the precedently moved nucleus by hydrodissection.

In case of an early-postoperative CBS, a transparent fluid is occurring...
