Long-term outcome of limbal-sparing lamellar keratoplasty in keratoglobus: A retrospective case series

Abstract

We report six eyes of five patients with keratoglobus who underwent limbal-sparing lamellar keratoplasty (LSLK) with 7 years of follow-up. In two patients’ three eyes, it was congenital and the rest had acquired keratoglobus from pellucid marginal degeneration combined with keratoconus. In LSLK, the peripheral corneal epithelium is dissected to include the stem cells and reflected along with conjunctival peritomy. The host cornea is de-epithelialized, stromal irregularities dissected, and then a corneoscleral graft denuded of Descemet’s membrane is anchored to a scleral ledge fashioned. Postoperatively, all received adequate tectonic support, and except for one posttrauma eye, the rest improved visually.
