Mp. Vrabec et Jj. Jordan, A SURGICAL TECHNIQUE FOR THE TREATMENT OF CENTRAL CORNEAL PERFORATIONS, Journal of refractive and corneal surgery, 10(3), 1994, pp. 365-367
BACKGROUND: Generally, corneal perforations of 2 mm in diameter or gre
ater are treated using graft material for tectonic support. A surgical
technique for the primary repair of such perforations without the use
of any additional tissue is presented. METHODS: This procedure is dem
onstrated by a case report. The technique involves creation of an elli
ptical defect out of a circular one, thus allowing for primary closure
, with the addition of glue. A definitive penetrating keratoplasty was
subsequently performed with several important modifications described
herein. RESULTS: A water-tight closure was obtained with this techniq
ue for 1 month while the inflammation subsided. Preoperative visual ac
uity was light perception. One year postoperatively, it was count fing
ers at 8 feet with mild irregular astigmatism. CONCLUSION: This techni
que is useful for perforations which are central, larger than 2 mm in
diameter, and when corneal or scleral material is not readily availabl
e for patch grafting.
