Visian Implantable Collamer Lens Behavior in Descemet Membrane Endothelial Keratoplasty Surgery.

Endothelial damage is one of the leading causes for anterior chamber phakic intraocular lens (AC-pIOL) explantation. In young patients, where the pIOL is explanted alone without lensectomy, an important anisometropia is left, unless an exchange with a posterior chamber (PC) pIOL is performed. However, in the event of corneal decompensation, there is no published evidence about the potential influence of a collamer-based PC-pIOL [implantable collamer lens (ICL)] on endothelial keratoplasty surgery. We report a case of severe endothelial damage after AC-pIOL implantation managed by the exchange of the AC-pIOL by an ICL, followed by Descemet membrane endothelial keratoplasty. Collamer-based PC-pIOLs seem to not affect Descemet membrane endothelial keratoplasty outcomes. ICL did not show any transparency loss. These results cannot be extrapolated to other non-collamer-based PC-pIOLs. Further studies with larger samples are necessary to confirm these outcomes.
