This book offers a comprehensive and accessible approach to the techniques and concepts of phacoemulsification. The author has worked to present these concepts in a precise yet simplified manner, ensuring that readers—whether ophthalmic surgeons, paramedical staff, or operating room assistants—can benefit from the valuable insights provided. It covers the technical details for each step of the phacoemulsification process, making it a practical resource for anyone involved in cataract surgery. The author, a second-generation ophthalmologist, draws inspiration from his father, Dr. Sham Toshniwal, whose practice and dedication to the field of ophthalmology have had a profound influence on his career. Beginning his own journey as an eye surgeon in 1994, the author was shaped by both the clinical expertise and the humanitarian efforts of his father, who founded a school for the blind and an eye bank. These experiences enriched the author's understanding of ophthalmology, balancing both practical skills and academic rigor. Through discussions with mentors and colleagues, such as Dr. Vilas Salgarkar, the author shifted his focus to the academic aspects of ophthalmology. This pivotal advice led him to participate in numerous regional, national, and international conferences, where he began presenting his own research, articles, and surgical videos. This book represents the culmination of years of clinical and academic growth, aimed at helping others navigate the intricate world of phacoemulsification with clarity and confidence.
