Summary

Late in-the-bag intraocular lens (IOL) dislocation occurs up to 30 years after cataract surgery and the prevalence ranges from 0.1% to 3.0%. Before the introduction of the continuous curvilinear capsulorhexis, late dislocation was very uncommon but since then several case reports and case series were observed. In-the-bag IOL dislocation is a well-known postoperative complication, especially in eyes with weak zonules as seen in pseudoexfoliation syndrome (PXF), high axial myopia, uveitis and retinitis pigmentosa (RP).

In this retrospective study, medical records of all patients with IOL related problems after implantation of one hydrophilic acrylic single-piece lens at the Department of Ophthalmology Graz, Medical University Graz, Styria, Austria are reviewed. Characteristics and predisposing factors for late in-the-bag, out-of-the-bag IOL dislocations, and haptic complications will be investigated and compared amongst each other or control patients. Incidence rates for each IOL complication will be calculated. For in-the-bag dislocations odds ratios for each predisposing factor will be calculated.
