Management of angle-supported intraocular lens and iridectomy in Descemet-stripping endothelial keratoplasty.

PROBLEM: Effective tamponade of a Descemet-stripping endothelial keratoplasty graft with a gas bubble requires that there is no route for the bubble to escape into the posterior chamber. SOLUTION: Exchange the angle-supported anterior-chamber intraocular lens (IOL) for an iris-enclaved Artisan IOL and position the IOL haptics over the peripheral iridectomy to occlude it to the extent that no gas can pass.
