Abstract Details


To report the outcomes of the use of an intraocular pinhole associated with DMEK to treat a failed irregular penetrating corneal graft with irregular astigmatism associated with a dense cataract.


Cançado Trindade Eye Institute


The left eye of a 63 year-old woman had a failing penetrating graft and dense white cataract limiting vision to counting fingers. Surgery included phacoemulsification with implantation of an intraocular pinhole followed by DMEK endothelial graft. A subtotal graft detachment was noticed in the initial postoperative period and graft re-bubble was carried out 1 week after initial procedure.


Graft attachment was achieved after rebubbling with corneal clearing. The intraocular pinhole remained stable and well centered. By three months, visual acuity improved from counting fingers to 20/40 and J2 uncorrected.


Intraocular pinhole implantation can improve irregular corneal astigmatism. It may expand the possibility of treating a failed penetrating graft with endothelial keratoplasty.
