Developed to address the limitations of existing treatments such as Deep Anterior Lamellar Keratoplasty (DALK), Penetrating Keratoplasty (PKP), Intacs, and Corneal Allogenic Intrastromal Ring Segments (CAIRS), DRLT provides a tissue preserving, minimally invasive solution with negligible rejection risk and rapid visual recovery. The text outlines the scientific foundations, evolution, biomechanics, and surgical design principles that led to the development of DRLT, offering readers a complete understanding of how this innovation transforms keratoconus management.\u003c\/p\u003e\n\u003cp\u003eChapters provide detailed, step by step guidance on lenticule preparation, pocket creation, surgical implantation, complication management, and postoperative care. The book is richly supported by clinical photographs, Pentacam maps, ASOCT scans, schematic illustrations, video clips enabling surgeons to visualize each stage of the procedure. It further includes real world clinical outcomes, comparisons with existing lamellar techniques, and future versions of DRLT under development, offering a forward-looking perspective for researchers and surgeons.\u003c\/p\u003e\n\u003cp\u003eThe book serves as an essential resource for corneal surgeons, refractive surgeons seeking innovative, safer alternatives to conventional corneal transplantation; ophthalmologists specializing in anterior segment surgery; cornea and refractive surgery fellows; postgraduate trainees (FCPS, FRCS, MS, MD) involved in keratoconus management. It is also valuable for optometrists involved in keratoconus diagnostics and contact lens fitting; vision science researchers and biomedical engineers; ophthalmology residents seeking surgical exposure to lamellar techniques; academic faculty teaching corneal and refractive surgery modules; eye bank professionals and tissue engineers interested in lenticule applications. By combining scientific rigor with practical surgical guidance, the book positions DRLT as a major advancement in global corneal surgery and a promising new standard for the treatment of advanced keratoconus.\u003c\/p\u003e\n\u003c\/div\u003e\u003cdiv\u003e\n\u003cp\u003e\u003cstrong\u003eDr. Zaman Shah\u003c\/strong\u003e (FCPS, MBBS) is a cornea specialist and professor of ophthalmology based in Peshawar, Pakistan.
