Abstract Details

Purpose:

To evaluate the possible risk factors for Posterior chamber (PC) intraocular lens (IOL) dislocation either within the capsular bag (in the bag dislocation) or IOL dislocation outside of the capsule (out of the bag dislocation).

Setting:

All subjects who sustained late IOL dislocation from January 2011 until May 2014 and presented to the Nagasaki University Hospital were included in the study. Retrospective study of all cases of PC IOL dislocation in this defined period.

Methods:

All cases had history of uncomplicated cataract surgery with implantation of PC IOL. Patients with history of trauma were excluded from the study. All patients were divided into two, in the bag dislocation group and out the bag dislocation group. The main outcome measures of the study were evaluation of risk factors for dislocation of both groups and determination of the interval between cataract surgery and dislocation.

Results:

In total, 52 eyes of 52 patients were included into the study. 36 eyes (69.23%) were in the bag dislocation and 16 eyes (30.77%) were out the bag dislocation. IOL dislocation was common in males (42 eyes=80.77%) than females (10 eyes=19.23%). Patients of the in the bag dislocation group were significantly older than those of the out the bag dislocation group at the time of initial IOL implantation and at the time of exchange surgery.

Conclusions:

The most prevalent risk factors in both groups were axial myopia in 18 eyes (34.61%), vitroretinal surgery in 16 eyes (30.77%), and pseudoexfoliation in 13 eyes (25%) in all cases. FINANCIAL DISCLOUSRE: NONE
