IOL Power by Kenneth J. Hoffer, MD will be the definitive resource worldwide for ophthalmologists who strive to increase the accuracy for all IOL calculations,especially for multifocal IOLs and overcoming the challenges that arise when treating patients that have had laser refractive surgery, such as RK, PRK, LASIK, and LASEK.

Inside the pages of IOL Power, Dr. Hoffer is joined by some of the most respected international physicians and physicists in the field of IOL power such as Aramberri, Haigis, Norrby, Olsen and Shammas. Together their expertise, spanning over 35 years, makes even the most difficult subjects easy to understand.

This volume will become the definitive reference source on the subject of IOL power calculation.

Some topics include:

  • Ultrasound velocities for axial length measurement
  • Optical AL (IOLMaster and Lenstar) in difficult eyes
  • Manual and automatic keratometry and instrumentation
  • Topography & Scheimpflug camera corneal power
  • Value of theoretic formulas
  • Formula personalization
  • Multifocal and toric IOLs
  • Aspheric IOLs
  • Effect of IOL tilt on astigmatism


Chapters Cover:

  • All aspects of obtaining the most accurate biometry
  • Available modern calculation formulas
  • Latest instruments
  • Problems that can arise, how to prevent and repair them


IOL Power by 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.

Autorenporträt
Kenneth J. Hoffer, MD was born in New York City; grew up in Upstate NY; and received his education at Siena College, Loudonville, NY, SUNY Upstate Medical University in Syracuse, NY, UCLA Santa Monica Hospital, and Wayne State University Kresge Eye Institute in Detroit, MI. He immediately set up practice in Santa Monica, CA in July 1972.

His interest in cataract surgery began early in his clinical career by beginning phacoemulsification after his first two months of practice, and IOL implantation two years later in 1974. Being in an extremely competitive environment, and to create superior patient outcomes, it stimulated him to introduce ultrasound axial length IOL power calculation. He created the American Intra-Ocular Implant Society (now ASCRS) and founded the Journal of Cataract & Refractive Surgery (previously AIOISJ). He wrote his original Hoffer formula in 1974 and, based on a pachymetry study in 1982, proposed the first prediction of ELP based on the eye's axial length. The Hoffer Q formula followed in 1993, using a tangent of K as an additional ELP predictor. To ease the calculation of formulas he first used early programmable calculators (HP- 65), and in 1993 produced the first program for IOL power calculation for personal computers (Hoffer Programs®). He also participated in the founding of the IOL Power Club in 2005 that has helped stimulate his interest in this subject.

After many years of teaching courses on the subject of IOL power at the Santa Monica Hospital IOL courses (2,800 surgeons attended over 10 years); at major meetings such as AAO, ASCRS, and ESCRS; performing research in this field; and publishing papers and book chapters, he was finally stimulated to write his first book on the subject to which he has devoted his professional career. This book is based primarily on the courses he has taught with the additional help of many friends in the field.
