Summary

IOL Powerby Kenneth J. Hoffer, MD will be the definitive resource for ophthalmologists who strive to increase the accuracy for multifocal IOLs and overcome the challenges that can come with treating patients that have had laser refractive surgery, such as PRK, LASIK, and LASEK. Inside the pages ofIOL Power, Dr. Hoffer is joined by some of the most respected physicians and physicists in the field of IOL power, together their expertise, spanning over 35 years, makes even the most difficult subjects easy to understand. Some topics include: Ultrasound velocities for axial length measurement IOLMaster in difficult eyes Manual keratometry and instrumentation Regression and theoretic formulas Formula personalization Multifocals and toric IOLs Aspheric IOLs Topography & Scheimpflug corneal powers Chapters Cover: All aspects of obtaining the most accurate biometry Available modern calculation formulas Latest instruments Problems that can arise, how to prevent, and then repair IOL Powerby Kenneth J. Hoffer, MD is structured in a logical manner so as to cover every facet of IOL power from the basics to the most complicated subjects to achieve the most accurate and precise calculations and should be in the hands of all ophthalmic surgeons, technicians, residents and students.
