Posterior Iris-claw Aphakic Intraocular Lens Implantation in Children is an interesting article. The authors have rightly pointed out that many complications of anterior iris claw aphakic intraocular lenses (IOL) are avoided. However, potentially the most common and serious complication of these posterior lenses is posterior dislocation, and this issue would require longer follow-up.
In the Discussion section the authors mentioned that trauma led to disenclavation of the nasal haptic of an IOL and they performed IOL exchange after disenclavating the temporal haptic also. It seems to be a more hazardous procedure than re-enclavating one haptic of the same IOL. Why was a new lens used? Was the existing lens damaged?
