To describe a new surgical technique in the management of corneal perforation in a patient with healthy endothelium.
Southend University Hospital, Southend, UK
A 69 year old male patient presented with a 2.5 mm round temporal corneal perforation having had a metallic corneal foreign body injury. Visual acuity at presentation was 6/36. The patient underwent uncomplicated small diameter (4mm) Descemet Stripping Automated Endothelial Keratoplasty (mini-DSAEK) to seal the perforation. The primary outcomes of interest were successful sustained closure of the perforation and surgical complications, with secondary outcomes of best spectacle corrected visual acuity (BSCVA, Snellen) and keratometric astigmatism (KA, Pentacam) at 6 months.
No surgical complications were reported and the graft remained clear at 6 months. Six months post operatively, final BSCVA was 6/6 (Snellen) with KA of-0.75 Diopters.
Tectonic mini-DSAEK is a safe technique in the management of corneal perforations too large for tissue adhesives, with a relatively low astigmatic profile and rapid visual recovery.
