PURPOSE: To report the use of Descemet stripping automated endothelial keratoplasty (DSAEK) and to treat visual loss in Descemet membrane (DM) breaks after forceps delivery.
METHODS: An 8-year-old boy presented with unilateral DM ruptures secondary to forceps delivery. Central, vertically oriented DM breaks significantly decreased visual acuity. Preoperative visual acuity was 20/80. A DSAEK was performed, the DM and endothelium were stripped from the recipient, and an 8.5-mm-diameter donor button consisting of posterior stroma and healthy endothelium was folded and implanted through a 5-mm incision. An air bubble was used to press the donor tissue against the recipient cornea, allowing it to attach without sutures.
RESULTS: Graft dislocation in the early postoperative period required surgical repositioning of the donor lenticule, which led to excellent anatomic and functional outcomes. There was a significant and rapid improvement of the best-corrected visual acuity, which was 20/50 at the first month and 20/32 at the seventh month postoperatively.
CONCLUSIONS: To our knowledge, this is the first report of a DSAEK in a child with DM tears after forceps delivery. Selective replacement of posterior corneal layers with DSAEK might be a promising alternative to penetrating keratoplasty to successfully treat endothelial or DM lesions during childhood.
