Anterior segment optical coherence tomography (AS-OCT) is a valuable tool in corneal transplantation surgery. In deep anterior lamellar keratoplasty (DALK), AS-OCT gives valuable information on preoperative decision process. AS-OCT image of the recipient cornea helps the surgeon to decide whether to proceed with a big bubble DALK or a manual dissection. Preoperative AS-OCT imaging of recipient stroma can also predict Descemet membrane perforation during big bubble induction. Intraoperative AS-OCT assures reaching the proper depth in order, and postoperatively, a surgeon can objectively assess the Descemet membrane and donor association and define complications such as a double anterior chamber. Before deciding for a Descemet membrane endothelial keratoplasty (DMEK), preoperative stromal scars can be identified with an AS-OCT and might affect the decision of the surgical procedure (DMEK or penetrating keratoplasty). After DMEK, graft detachment can be visualized by AS-OCT and treated accordingly.

I am very proud and excited to introduce to you this book, which provides many interesting indications on how to better understand and handle the world of opticalcoherence tomography (OCT). Reading the chapters, you will be aware that this device is extremely important not just in the clinical practice of retinal diseases, but is also very useful as a surgical tool. Moreover, application of OCT has crossed the borders of the retina and is currently being applied to corneal diseases and glaucoma. I amconfident you will find enough useful information to improve your practice using OCT and to provide a better quality of care for your patients.

Deep anterior lamellar keratoplasty (DALK) is the mainstay of treatment for corneal pathologies sparing the endothelium. This lamellar surgery has undergone a revolution in the past decades. Various techniques and their modifications have been described to make it safe and reproducible so that it can be performed not only by experts but also the novice corneal transplant surgeons. This book describes the evolution of DALK, indications, preoperative evaluation, the various methods of performing DALK and the postoperative outcomes. The issues related to procurement of donor corneas for such cases are discussed. The "different strokes" in DALK include the conventional Melles and the "Big bubble" technique and also the newer modifications such as "Double bubble" technique, cannula assisted DALK, groove and peel technique as well as diamond blade-guided DALK. The different types of modifications presented by eminent lamellar corneal transplant surgeons from all over the world, in this book are an endeavor to make DALK feasible by all corneal transplant surgeons.

"DSEK: What You Need to Know About Endothelial Keratoplasty provides a comprehensive background of EK, where it is today, and where it is headed in the future. Francis W. Price, MD. who was the first to complete DSEK in the United States, along with Marianne Price, PhD, have designed this text to offer a special emphasis on how to perform surgeries along with preventing and managing complications. In addition, a diverse group of contributing authors provides a wide array of insights and tips for better patient outcomes."--BOOK JACKET.

Integrated or microscope-integrated intraoperative ocular coherence tomography (i2OCT or mi-OCT, respectively) has revolutionized real-time augmentation of the surgical operating field. While corneal and retinal specialists have immediately found uses for this technology, others are beginning to use it to improve outcomes and flatten the learning curve. This book presents the use of i2OCT in pediatric ocular surgery. Case scenarios in pediatric retinal disease, corneal lamellar keratoplasty, and even pediatric cataract surgery are discussed. More novel applications highlighted include its use to identify the levator muscle in oculoplastic surgery, especially re-operations, and to assess the results of glaucoma drainage devices. Identifying extraocular muscles in re-operation for strabismus ensures minimal tissue disruption during surgery. Complex pediatric cataract surgeries can be performed far more simply and effectively using integrated ocular coherence tomography technology. This volume provides invaluable information to both early career and experienced pediatric ocular specialists, as well as any researchers who are likely to encounter i2OCT or mi-OCT technology in the future.

An explanation of this new technology, consisting of optical coherence tomography integrated to the microscope in both anterior and posterior lamellar corneal transplants (DALK, DSAEK, DMEK). The advantages of visualizing the different layers of the host and donor cornea, with specific emphasis in the Descemet-stroma interphase, are explained in the written work and captured in the intraoperative images. This technology makes the procedure safer, increases the surgery success rate and consequently improves the postoperative results in the patient. The surgical technique of the lamellar transplants and its benefits are explained. The advantages of this new technology are analyzed, including visualizing the corneal planes, checking the tissue orientation and ensuring the correct execution of critical surgical steps; all of these help in reducing the technical difficulty of the procedure. Likewise, it is explained that by providing direct transurgical visualization in a screen, there is a potential teaching and academic advantage.

The Novartis Foundation Series is a popular collection of the proceedings from Novartis Foundation Symposia, in which groups of leading scientists from a range of topics across biology, chemistry and medicine assembled to present papers and discuss results. The Novartis Foundation, originally known as the Ciba Foundation, is well known to scientists and clinicians around the world.
