Abstrakt: Purpose: We describe cases of dislocation or subluxation of the WIOL-CF ® polyfocal full-optics intraocular lens (IOL) and suggest a consistent pattern and possible mechanism for the IOL instability.
Methods: This is a retrospective case series of five consecutive eyes in three patients with WIOL-CF ® IOL instability at Keimyung University Dongsan Medical Center and Kimkisan Eye Center from 2012 to 2014. The medical records and ocular exam data for these patients were analyzed.
Results: A 50-year-old male had uneventful phacoemulsification in both eyes with WIOL-CF ® IOL implantation. At 27 months after surgery, the patient was referred to our clinic with a dislocated IOL in the left eye. The IOL in the right eye was dislocated in the same pattern 38 months after cataract surgery. Another 50-year-old male, who had phacoemulsification and WIOL-CF ® IOL implantation in both eyes, was referred to our clinic following diagnosis of a subluxated IOL. Both IOLs were well centered; however, the infranasal aspect of the IOLs tilted posteriorly, and the supratemporal portion the IOLs tilted anteriorly, with overlying iris atrophy in a symmetric pattern. The inferonasal continuous curvilinear capsulorrhexis (CCC) edge was dragged superotemporally, and the supratemporal CCC edge was identified on the posterior surface of the IOL. A 16-year-old female had uneventful phacoemulsification and WIOL-CF ® IOL implantation to treat a cataract in the right eye, and 3 years later, the IOL tilted with the same pattern as the previous case.
Conclusions: Years after uncomplicated phacoemulsification, an implanted WIOL-CF ® IOL may tilt and dislocate in the absence of trauma, in a consistent and characteristic pattern.
