Minimally invasive surgery technique for re-enclavation of prepupillary iris-claw IOLs.

BACKGROUND

Disenclavation is a common complication of prepupillary iris-claw intraocular lenses (IOL). We present a new minimally invasive revision surgery technique for reenclavation of prepupillary iris-claw IOLs using standard 23 Gauge (G) vitrectomy instruments.

HISTORY AND SIGNS: Three cases of revision surgery by unilaterally dislocated prepupillary iris-claw IOLs are presented.

THERAPY AND OUTCOME: Two 20 G sideports 90 degrees apart were constructed. Healon 10® was injected to maintain the anterior chamber. A standard enclavation needle was introduced to rotate the optic into correct position and a 23 G endgrasping forceps was used to grasp and stabilize the IOL for enclavation. The reenclavation was successful in all three cases and the mean visual acuity improved from preoperatively 0.1 (range counting fingers [CF] to 0.25) to 0.6 (range 0.4 to 0.8) with no significant induction of astigmatism.

CONCLUSIONS

This minimally invasive reenclavation technique for repositioning of the prepupillary iris claw IOL appears to lead to successful and rapid visual rehabilitation.
