Original articleLate In-the-Bag Spontaneous Intraocular Lens Dislocation: Evaluation of 86 Consecutive Cases
Section snippets
Materials and Methods
This retrospective study was designed to analyze posterior chamber IOLs spontaneously dislocated within the capsular bag after cataract surgery. All explanted IOLs within the capsular bag that were forwarded to the Intermountain Ocular Research Center at the John A. Moran Eye Center, University of Utah, for pathologic evaluation from March 2000 through March 2008 were included in the study. They were submitted to the laboratory immersed in fixative, such as 10% neutral buffered formalin. The
Results
Surgeons submitted 86 IOLs that were dislocated within the capsular bag to the Pathology Laboratory of the Intermountain Ocular Research Center over this 8-year period. Fifty-nine of the total 86 IOLs were submitted from January 2006 through March 2008. Complete patient history information could not be obtained for every IOL specimen. Information on the visual outcome of each case generally could not be collected by the time the specimens were submitted. Table 1 shows the materials and designs
Discussion
Decentration and dislocation of IOLs are serious optical malpositioning complications of cataract surgery. Reports during the 1980s showed that IOLs dislocated with a cumulative incidence from 0.2% to 3% when placed within the capsular bag. More recent data are difficult to assess. Intraocular lenses seem to dislocate in a bimodal distribution with respect to time. These dislocations, referred to as early and late, generally are initiated by 2 causes: improper fixation within the capsular bag
