Spontaneous Late Intraocular Lens and Capsule Tension Ring Dislocation

Abstract

In this report, three cases with pseudoexfoliation (PEX) and advanced age with spontaneous intraocular lens (IOL) and capsule tensionring (CTR) dislocation were presented. All of our cases experienced progressive vision loss without an episode of strenuous physicalactivity, trauma, or any other ocular disease. Spontaneous dislocation was observed 2.5 to 8 years after uneventful phacosurgery. Eachpatient underwent complete IOL and CTR removal combined with anterior chamber IOL implantation. No complications were noticedduring follow-up. As a result, capsule tension ring does not prevent late IOL dislocation after uncomplicated phacosurgery in the presenceof PEX. Therefore, close follow-up is essential for patients with PEX.
