In-the-bag intraocular lens dislocation.
OBJECTIVE
To describe the presenting characteristics and management alternatives of posterior chamber intraocular lens (PC-IOL) dislocation secondary to dehiscence of the zonules supporting the capsular bag.


METHODS
Observational case series.


METHODS
Multicenter retrospective analysis of the surgical treatment and predisposing factors associated with 25 eyes of 22 patients with dislocation of the PC-IOL encased within the capsular bag secondary to dehiscence of the zonules supporting the capsular bag.


RESULTS
The dislocated in-the-bag PC-IOL was replaced with an anterior chamber intraocular lens in 60% or repositioned/exchanged and scleral fixated in 40% of eyes. Associated conditions included pseudoexfoliation syndrome 44%, uveitis 16%, and trauma 16%. There was no identifiable cause in 24% of eyes.


CONCLUSIONS
In-the-bag PC-IOL dislocations are an unusual, sometimes bilateral, late complication of cataract surgery that can be managed by exchange with an anterior chamber intraocular lens or by PC-IOL repositioning or replacement with scleral fixation. The most common associated condition was pseudoexfoliation.
