Endothelial Keratoplasty: A Comprehensive Guide to Corneal Surgery

Endothelial keratoplasty (EK) is a revolutionary surgical technique that has significantly improved the treatment of various corneal diseases. This minimally invasive procedure has gained popularity among ophthalmologists due to its efficacy and quicker recovery time compared to traditional full-thickness penetrating keratoplasty.

Understanding the Anatomy and Clinical Aspects of Endothelial Dysfunction

The endothelial layer of the cornea plays a crucial role in maintaining the health and clarity of the cornea. Deficiencies in this layer can lead to various eye disorders, including pseudophakic bullous keratopathy and Fuchs’ dystrophy. A thorough understanding of the anatomy and clinical aspects of endothelial cell dysfunction is essential for effective treatment and management of these conditions.

A Brief History of Endothelial Keratoplasty

Endothelial keratoplasty has evolved over the years, with significant advancements in techniques and outcomes. From the early days of full-thickness corneal transplantation to the development of selective cell transplantation, EK has become a preferred method for treating corneal diseases. The history of EK is a testament to the relentless pursuit of better treatment options for patients with corneal disorders.

Surgical Procedures in Endothelial Keratoplasty

Several surgical procedures are used in endothelial keratoplasty, each with its own set of indications and contraindications. These include Descemet’s stripping endothelial keratoplasty (DSEK), predescemet’s endothelial keratoplasty (PDEK), ultrathin DSEK, Descemet’s membrane endothelial keratoplasty (DMEK), and trocar anterior chamber maintainer. Each procedure is designed to address specific corneal conditions and offers unique benefits and challenges.

Special Topics in Endothelial Keratoplasty

Endothelial keratoplasty is not without its challenges. Complicated cases, such as those involving glued IOL, cataract extraction & IOL implantation, glaucoma, failed grafts, and scarred corneas, require specialized knowledge and skills. Ophthalmologists must be well-versed in managing these complex situations to ensure optimal outcomes for their patients.

Surgical Outcomes and Complications in Endothelial Keratoplasty

While endothelial keratoplasty has proven to be an effective treatment for various corneal diseases, it is not without its potential complications. These can include graft rejection, infection, and vision disturbances. A thorough understanding of the potential outcomes and complications is crucial for ophthalmologists to provide their patients with the best possible care.

Future Trends in Endothelial Keratoplasty

As technology continues to advance, endothelial keratoplasty is likely to evolve further. Researchers are exploring new techniques and materials to improve the efficacy and safety of EK procedures. The future of corneal surgery holds much promise, with potential advancements in cell therapy, gene therapy, and bioengineering.

Endothelial keratoplasty is a rapidly evolving field in ophthalmology, offering hope to patients with corneal diseases. This comprehensive guide provides ophthalmologists with the knowledge and skills necessary to perform these complex procedures and manage potential complications. With its detailed explanations, high-quality images, and expert insights, this book is an invaluable resource for anyone involved in corneal surgery.
