Purpose: To describe the clinical outcomes of Descemet stripping automated endothelial keratoplasty (DSAEK) in a series of patients affected by progressive endothelial cell loss leading to corneal decompensation with Descemet membrane (DM) breaks caused by obstetrical forceps trauma. Methods: Seven amblyopic eyes of 7 patients affected by unilateral visual loss due to increasing corneal edema were included in the study. In all eyes, slit-lamp examination revealed typical DM breaks and diffuse corneal edema: these findings were compatible with a history of obstetrical forceps-assisted delivery. DSAEK was performed in all cases (in 3 eyes combined with phacoemulsification and intraocular lens implantation); visual acuity, refraction, corneal topography, and endothelial cell density were recorded preoperatively and 1 year after surgery. Results: Visual acuity improved in all cases by at least 2 Snellen lines; topographic astigmatism lower than 2.5 diopters was associated with better visual recovery. No intraoperative or postoperative complications were reported, and the corneas remained clear throughout the follow-up. Conclusions: In eyes with endothelial decompensation secondary to DM breaks caused at birth by forceps injury, DSAEK can be performed uneventfully and restore cornea clarity. However, visual recovery is limited by the preexistent amblyopia, usually resulting from anisometropia and/or high-degree unilateral astigmatism. The results obtained in our patients suggest that low-degree astigmatism may be associated with better visual outcomes.

Abstract

Purpose: To describe the clinical outcomes of Descemet stripping automated endothelial keratoplasty (DSAEK) in a series of patients affected by progressive endothelial cell loss leading to corneal decompensation with Descemet membrane (DM) breaks caused by obstetrical forceps trauma. Methods: Seven amblyopic eyes of 7 patients affected by unilateral visual loss due to increasing corneal edema were included in the study. In all eyes, slit-lamp examination revealed typical DM breaks and diffuse corneal edema: these findings were compatible with a history of obstetrical forceps-assisted delivery. DSAEK was performed in all cases (in 3 eyes combined with phacoemulsification and intraocular lens implantation); visual acuity, refraction, corneal topography, and endothelial cell density were recorded preoperatively and 1 year after surgery. Results: Visual acuity improved in all cases by at least 2 Snellen lines; topographic astigmatism lower than 2.5 diopters was associated with better visual recovery. No intraoperative or postoperative complications were reported, and the corneas remained clear throughout the follow-up. Conclusions: In eyes with endothelial decompensation secondary to DM breaks caused at birth by forceps injury, DSAEK can be performed uneventfully and restore cornea clarity. However, visual recovery is limited by the preexistent amblyopia, usually resulting from anisometropia and/or high-degree unilateral astigmatism. The results obtained in our patients suggest that low-degree astigmatism may be associated with better visual outcomes.
