Follow-up of Endothelial Cell Loss After Explantation of Iris-Claw IOL
Narrative Responses:
Purpose
To report the evolution of endothelial damage after explantation of Iris-Claw IOL due to severe endothelial loss.
Methods
Retrospective study including 29 eyes implanted with the Iris-Claw IOL and explanted several years later because of a severe endothelial loss. The endothelial cell density was calculated with the non contact Topcon SP2000 or SP3000 specular microscope.
Results
There were no history of cell loss in the first postoperative months after the Iris-Claw implantation. The mean time of explantation was 90 months and the mean cell density was 1000 cells/mm2 at that time. The endothelial density remained stable in half of eyes one year after the explantation. A mild or moderate loss (less than 50 % compared to pre-explantation) occurred in half of eyes. The endothelial cell count remained stable in patients with a longer follow-up.
Conclusion
The endothelial cell loss is a major complication of the Iris-Claw IOL. Around 20 % of eyes require an explantation after ten years. The endothelial loss increases in the early postop of explantation in half of cases due to the surgical trauma, but seems to be stable over time.
