Deep Lamellar Keratoplasty Combined With Cataract Surgery

Abstract

We used a surgical technique that combines deep lamellar keratoplasty, phacoemulsification, and intraocular lens implantation for treating patients with cataract and corneal stromal disease. Deep lamellar dissection of the cornea was first performed with viscoelastic substances (hyaluronate sodium) until the highly transparent Descemet membrane solely remained. We then created a short corneal tunnel to perform phacoemulsification with low vacuum and intraocular lens implantation. The resilience of the Descemet membrane ensured excellent viewing of the whole anterior chamber as well as the surgical conditions of a closed system. At the end of surgery, a full-thickness donor button was sutured into the recipient bed after its Descemet membrane was stripped. This technique was effective in these 4 patients with cataract and dense corneal opacity.
