EW NEWS & OPINION 9 B onnie An Henderson, MD, Boston, is the newest of six clinical ophthalmologists now serving on the ASCRS Executive Committee. Dr. Henderson officially assumed her post at the 2014 ASCRS•ASOA Symposium & Congress in April. During her first term, she will serve as secretary. Other members of the Executive Committee include: Richard A. Lewis, MD, Sacramento, Calif., president; Robert J. Cionni, MD, medical director, The Eye Institute of Utah, and adjunct clinical professor, John A. Moran Eye Center, University of Utah, Salt Lake City, vice president; Eric D. Donnenfeld, MD, co-chairman of cornea, Nassau University Medical Center, East Meadow, N.Y., immedi- ate past president; David F. Chang, MD, Los Altos, Calif., past president; and Kerry D. Solomon, MD, associate professor of ophthalmol- ogy, Medical University of South Carolina, Charleston, treasurer. Dr. Henderson is well known in the world of cataract and refractive surgery. A renowned expert specializing in complicated anterior segment surgery, she is currently a partner at Ophthalmic Consultants of Boston and a clinical professor at Tufts University School of Medicine. Dr. Henderson com- pleted her ophthalmology residency at Harvard Medical School, Massa- chusetts Eye and Ear Infirmary. She graduated from Dartmouth College and from Dartmouth Medical School with high honors. In addition to her role as secretary of the ASCRS Executive Committee, Dr. Henderson serves on multiple committees and is the associate editor for the Journal of Refractive Surgery and cataract section editor for EyeWorld. She is also on the editorial boards of Eyenet Magazine of the American Academy of Ophthalmology (AAO), Ocular Surgery News, Cataract and Refractive Surgery Today, and Advanced Ocular Care. Dr. Henderson is a reviewer of eight ophthalmological journals, February 2014 Intraocular power adjustable technologies Joshua Ford, MD, Liliana Werner, MD, PhD, Nick Mamalis, MD Being able to adjust a lens power is adding a new dimension to cataract procedures. In this overview, investigators honed in on available ad- justable intraocular lens technology as well as that under development, discussing the principles of these and where they stand in the pipeline. Included here was technology such as the mechanically adjustable IOL, the multicomponent IOL, the magnetically adjustable IOL, and the repeatedly adjustable IOL, which all require second surgical procedures to implement changes. The magnetically adjustable IOL, the liquid crystal wirelessly controlled IOL, and other IOLs that can be noninva- sively tweaked were also highlighted. Investigators detailed the range of studies available for the Light-Adjustable Lens, which is nearing the final stages of evaluation in the United States. This lens is already available in Mexico and Europe. Laboratory science: Penetration of moxifloxacin through crosslinked corneas Gilad Litvin, MD, Shmuel Ben Eliahu, DVM, Michael Rotenberg, MD, Arie L. Marcovich, MD, David Zadok, MD, Guy Kleinmann, MD Once an eye has undergone crosslinking, does this compromise the ability of therapeutic agents to penetrate the cornea? Investigators set out to determine whether or not a crosslinked rabbit cornea was still amenable to moxifloxacin (Vigamox) penetration. In the study, 1 month after undergoing corneal collagen crosslinking treatment 1 drop of moxifloxacin was applied to 10 crosslinked rabbit eyes. Then 3 more drops were applied at 15-minute intervals. Drops were also applied to the untreated fellow eye. When investigators analyzed moxifloxacin levels for all 20 eyes they determined that there was no statically significant difference between the antibiotic penetration in crosslinked versus non-crosslinked eyes. Investigators found a mean penetration of 2.26 μg/mL in treated eyes compared with 2.43 μg/mL in untreated eyes. They concluded that prior crosslinking treatment did not influence moxifloxacin penetration in the anterior chamber of rabbit eyes. Corneal power by ray tracing Giacomo Savini, MD, Antonio Calossi, DipOptom, Massimo Camellin, MD, Francesco Carones, MD, Marco Fantozzi, MD, Kenneth J. Hoffer, MD In this multicenter retrospective study, investigators set out to determine whether corneal ray tracing with a Scheimpflug camera and Placido-disk corneal topographer can accurately measure excimer laser-induced refractive changes. Included were 72 eyes of 54 patients who had undergone either myopic or hyperopic excimer laser surgery. Investigators determined that with myopic correction the difference between postoperative and preoperative simulated K values underesti- mated the refractive change and particularly for higher amounts of correction was poor. However, there was an excellent correlation seen between refractive change and the difference between the postoperative and preoperative mean pupil power. This neither over- nor underesti- mated the refractive change. Investigators concluded that after excimer laser refractive surgery, corneal power can accurately be measured using corneal ray tracing.
