World view IOL formulas I recall hearing the term "dream team," for the first time when it was used to describe the 1992 U.S. men's Olympic basketball team the first year that professional players were allowed to compete. The team featured all-star players such as Michael Jordan, Scottie Pippen, Magic Johnson, Larry Bird, Patrick Ewing, Charles Barkley, and others. Similarly, if I could create my own "dream team" of ophthalmologists to discuss IOL calculations, the people who contributed to this month's EyeWorld would be my version. In this edition, Giacomo Savini, MD, and Thomas Olsen, MD, discuss their methods and newest generation of IOL formulas. Others from around the globe have found that averaging the formulas for a consensus power appears to be more accurate. Kazuno Negishi, MD, and Harry Geggel, MD, quote success rates of reaching within 0.5 D of the target 63% and 70% of the time, respectively, with the consensus method, and Wolfgang Haigis, PhD, discusses his approach to resolving unexpected postoperative refractive errors. Graham Barrett, MD, has developed a new formula for toric IOL calculation. His formula estimates the posterior corneal contribution and includes IOL position information to improve the accuracy. He credits Warren Hill, MD, for teaching him to utilize several technologies for accurate measurements. Dr. Barrett also discusses new technologies, such as an app for the smartphone that can help with marking the steep axis and aligning the toric IOL. (Warning: Many ophthalmologists may need assistance from their children or grandchildren to explain these newer technologies such as apps. #joking) Doug Koch, MD, and Li Wang, MD, remind us that while normal eyes have accurate outcomes with the current third- and fourth-generation formulas, long axial lengths can have unexpected outcomes. They discuss the necessary IOL formula mod- ifications that will help prevent the hyperopic surprise in long axial lengths of greater than 25 mm. Additionally, they advise toric power adjustments for these long eyes. To round out my "dream team," Robert Weinstock, MD, Jonathan Solomon, MD, Sean Ianchulev, MD, and Shamik Bafna, MD, discuss the science behind intra- operative aberrometry and offer their clinical pearls. After reading this month's edition from the ophthalmic dream team, I am certain readers will earn a gold medal in IOL power calculations.

Waring III, MD, FACS, FRCOphth G eorge O. Waring III, MD, FACS, FRCOphth, renowned ophthalmologist and pioneer in refractive surgery, has died. He was 73. Born in Buffalo, N.Y., Dr. Waring received his medical degree from Baylor College of Medicine, Houston, in 1967. He began his academic career in 1974 as assistant professor of ophthalmology at the University of California, Davis. Joining Emory University in Atlanta in 1979, Dr. Waring was later principal investigator of the Emory-sponsored investigations of LASIK, receiving the first physician-sponsored investigational device exemption from the FDA. He was also national director of the PERK study of radial keratotomy (RK). He was adjunct professor emeritus of ophthalmology, Emory University School of Medicine, and in private practice. He specialized in vision correction surgery, LASIK, RK, IOL implants, and cataract and corneal surgeries. "Your vision is the most precious of all the senses," he said on his website. "My vision is to help you see clearly and experience life free from glasses or contacts." In 2004, he received the Life Achievement Honor Award from the American Academy of Ophthalmology and the Castroviejo Medal from the Cornea Society, among many awards. He was also the editor-in-chief of the Journal of Refractive Surgery from 1989 to 2010. Dr. Waring's survivors include his sons, George O. Waring IV, MD, also an ophthalmologist; John Waring, MD; Matthew Waring; and daughter Joy Waring Harty. An expanded story on Dr. Waring and his contributions to ophthalmology will be included in the March 2015 edition of EyeWorld. EW
