Abstract

Corneal pathology combined with a cataract is a common entity in older patients. For these patients, penetrating keratoplasty (PKP) with extracapsular cataract extraction (ECCE) and intraocular lens (IOL) implantation, often termed the “triple procedure” has been the preferred treatment of choice. However, when corneal endothelium is healthy, deep lamellar keratoplasty (DLK) procedure has been gaining in popularity as an alternative to PKP. In this process, the corneal stroma needs to be totally excised to leave only the bare Descemet’s membrane; then the stroma is replaced by a full-thickness donor graft. This results in no obvious scar formation between the host and donor corneal interface. The main advantages of DLK include elimination of allograft reaction to the endothelium and prevention of long-term endothelial loss, while retaining a favorable postoperative visual function. Therefore, the opportunity to perform two or more ophthalmic operations simultaneously with DLK has increased in recent years in patients with corneal opacities and other pathologies such as a cataract, vitreoretinal disorders or limbal stem cell deficiency. The authors describe here a technique which combines DLK and cataract surgery. We were able to demonstrate that the resilience of the bared Descemet’s membrane can withstand all the steps of standard phacoemulsification in patients with a cataract and corneal stromal disease. This option is doubly beneficial to the patients, since it combines the optimal operative conditions of closed cataract surgery and a lamellar corneal procedure, both done during the same surgery.
