Pre-Descemet's Endothelial Keratoplasty (PDEK)

Corneal transplantation is a widely practised surgical procedure. Lamellar techniques are favoured replacing penetrating keratoplasty (PK). Endothelial keratoplasty (EK) has been adapted as an alternative in the treatment of corneal endothelial disorders whereby Descemet?s membrane and the endothelium are replaced. Pre-Descemet?s endothelial keratoplasty (PDEK) is the latest surgical technique for corneal transplantation.

This book is a step by step guide to PDEK for practising ophthalmologists.

Divided into five sections, the text begins with the basics explaining corneal anatomy, pre-operative assessment, general techniques in keratoplasty, and the principles of PDEK.

The following chapters discuss surgical techniques, special situations, and complications and results. The text covers numerous clinical scenarios and concludes with a section on miscellaneous topics such as OCT guided PDEK, eye bank preparation, and cosmetic iris implant complications.

The text is further enhanced by surgical photographs and includes an interactive DVD ROM demonstrating PDEK techniques.
