Spontaneous Posterior Dislocation of Soemmering Ring 34 Years after Cataract Surgery

Introduction

Soemmering ring is the capsular remnants of a cataractous lens, which contain some retained cortical cells and newly formed lens substance [1], [2], [3]. These cells and this substance are encysted between the anterior and the posterior capsules of the lens [1], [2], [3]. The epithelium proliferates and lines the posterior capsule and grows around the margin of the anterior capsule [2], [3], [4]. It forms a ring around the periphery of the capsular bag [2]. The nucleus of the lens is, per definition, always absent after either trauma or operative intervention [1], [2]. The fusion between the anterior capsule and the posterior capsule protects the cells and lens fibers from the lytic aqueous humor [3], [4]. The ring is more often formed by several separated irregular masses than by a complete ring structure [2]. It lies in the retro-iridial space [2], [3], [4].
