Abstract Details


To explore the indications, efficacy, and complications of anterior lamellar keratoplasty (LKP) for peripheral corneal perforation


Centro Hospitalar Lisboa Central - Cornea Department


Retrospective case study analyses of 10 patients (10 eyes) with the diagnosis of peripheral corneal ulceration between 2010 and 2012. Anterior lamella graft were obtain from the microkeratome cuts from Dsaek preparation. All patients were submitted to semi lunar lamellar keratoplasty and were sutured with 10-0 monofilament. Postoperative visual acuity (VA), corneal clarity, astigmatism, and complications were studied during a follow-up of 3 to 21 months.


The initial causes of corneal perforation were mostly Terrien's marginal degeneration (3 eyes) and Mooren's ulcer (3 eyes) . The lamellar graft attached to the host well and was transparent in all eyes following LKP. VA in 8 eyes improved after LKP, and best-corrected VA in 3 eyes was 0.5 or better. The mean corneal astigmatism was approximately 6D three months postoperatively, and this decreased to approximately 3D nine months postoperatively when sutures were removed. The postoperative complications included secondary glaucoma (2 eyes) and recurrence of primary diseases (2 eyes).


nterior Lamellar Keratoplasty seems to be a safe and effective procedure to restore the integrity of the eyes with peripheral corneal perforation. Moreover, the well-matched graft configuration can reduce the postoperative astigmatism, helping restore or improve the vision in most cases. FINANCIAL INTEREST: NONE
