Long-term endothelial cell loss after traumatic dislocation and repositioning of Artisan phakic IOL.

PURPOSE: To evaluate long-term endothelial cell loss after traumatic dislocation and repositioning of an Artisan phakic intraocular lens (PIOL).

METHODS

Traumatic PIOL dislocation occurred in the patient's left eye 4 months after uneventful implantation for unilateral congenital myopia. Using the Konan semi-automated analysis method, endothelial cell density was measured preoperatively, before Artisan repositioning, and 1, 2, and 4 years after primary implantation.

RESULTS

Endothelial cell density was 2770 cells/mm2 preoperatively and 2634 cells/mm2 before Artisan repositioning. After successful repositioning, endothelial cell density progressively decreased--1, 2, and 4 years from primary implantation, endothelial cell density was 2582, 2524, and 2538 cells/mm2, respectively, corresponding to losses of 6.8%, 8.9%, and 8.4%, respectively.

CONCLUSIONS

Progressive and long-term endothelial loss after traumatic dislocation and repositioning of the Artisan PIOL may be comparable to that reported after uneventful implantation.
