11 EW NEWS & OPINION May 2015 P hilippe Sourdille, MD, and Marcelo Ventura, MD, PhD, were honored by the American Society of Cataract & Refractive Surgery (ASCRS) and La Asocia- ción Latinoamericana de Cirujanos de Catarata, Segmento Anterior y Refractiva (Latin American Society of Cataract & Refractive Surgeons, ALACCSA-R/LASCRS) during the ASCRS Opening General Session of the 2015 ASCRS•ASCRS Symposium & Congress. Established by ASCRS in 2004, the Honored Guest Award is given to luminaries whose life-long clinical, research, or ophthalmic in- dustry accomplishments allow them to offer a unique perspective on the current state of ophthalmology and the healing arts. Philippe Sourdille, MD Dr. Sourdille is an ophthalmic leg- acy; he, his father, and his grand- father were all French ophthalmol- ogists. He designed and patented several IOL models and has main- tained a focus on posterior capsule opacification and the treatment of postoperative inflammation Dr. Sourdille is currently a consultant in Europe, successively working with Cornéal Laboratoires, Croma Pharma, Cristalens, Medicontur, and Aptissen. Until 2002, he practiced at a leading French ophthalmology center that was founded by his grandfather, Clinique Sourdille. Dr. Sourdille has had a career filled with many milestones. In 1991, as president of the French Im- plant Society, Dr. Sourdille organized a club that would later become the European Society of Cataract & Refractive Surgeons (ESCRS). Along with Stephen Obstbaum, MD, and Emmanuel Rosen, MD, Dr. Sourdille helped to merge the ESCRS and ASCRS journals into what is now the Journal of Cataract & Refractive Surgery (JCRS). In 1974, Dr. Sourdille helped to organize a symposium at which Charles D. Kelman, MD, performed the first phacoemulsification pro - dure. At the Société d'Ophtalmol- ogie de Paris in 1978, he presented an evolution of the extracapsular cataract extraction technique. Three years later, Dr. Sourdille and his Uni- versity of Nantes colleagues helped to pave the way to the intracapsular placement of IOLs with the "in-the- bag"/Nantes technique. In the journal . . . Pseudoexfoliation and in-the-bag subluxation or dislocation Erica Liu, MD, Scott Cole, MD, MS, Liliana Werner, MD, PhD, Fritz Hengerer, MD, Nick Mamalis, MD, Thomas Kohnen, MD, PhD, FEBO In this retrospective case series, investigators assessed the presence of pseudoexfoliation in capsular bags that had spontaneously dislocated and that were subsequently explanted. Contained in these bags were either an IOL or IOL-CTR (capsular tension ring). Among the IOLs were 3-piece hydrophobic acrylic, 1-piece hydrophobic acrylic, 3-piece silicone, 1-piece hydrophilic acrylic, 3-piece hydrophilic acrylic, and 1-piece poly(methyl methacrylate) (PMMA) lenses. The CTRs were all PMMA. Out of 40 specimens, 24 showed excessive contraction of the capsular bag with capsulorhexis phimosis. Meanwhile, investigators found evidence of pseudoexfoliation in 24 cases, with just 13 having a clinical history or signs of pseudoexfoliation. They concluded that pseudoexfoliation might play a larger role than thought in dislocation cases. Such under diagnosis, they felt, might call for new preoperative and postoperative diagnostic measures and follow-up. Corneal changes with accommodation using dual Scheimpflug photograph Irene Sisó-Fuertes, MSc, Alberto Domínguez-Vicent, MSc, Antonio del Águila-Carrasco, MSc, Teresa Ferrer-Blasco, PhD, Robert Montés-Micó, PhD What effect does accommodation have on corneal parameters and aberrations? In a recent prospective cross-sectional study, investigators evaluated this in 12 eyes of 7 subjects. They determined that during ac- commodation there were no significant changes found for any c rneal zone measured. While for various corneal zones there were statistically significant differences found, investigators believed these to e con- stant with accommodation. When it came to corneal aberrations, with accommodation a stable lineal trend was found. They concluded that during accommodation corneal aberrations as well as different parame- ters in various zones of the cornea were stable. Prediction of refractive outcomes with toric IOL Adi Abulafia, MD, Graham D. Barrett, MD, Guy Kleinmann, M , Shay Ofi , MD, Adi Levy, BSc, Arie L. Marcovich, MD, PhD, Adi Michaeli, MD, Douglas D. Koch, MD, Li Wang, MD, PhD, Ehud I. Assia, MD The aim of this study involving toric lenses was to compare how differ- ent methods to measure and predict postoperative astigmatism fared. In this retrospective case series, postoperative corneal astigmatism of toric IOL patients were measured with 3 devices—the IOLMaster 500 (Carl Zeiss Meditec, Jena, Germany), optical low-coherence reflect m- etry-based LENSTAR LS 900 (Haag-Streit, Koniz, Switzerland), and the Atlas topographer (Carl Zeiss Meditec). These measurements were all compared with the manifest astigmatic refractive outcome. Then vector analysis and calculation methods were used to determine the error in the predicted astigmatism. Investigators found that with the Alcon and Holladay toric calculators the errors in predicted residual astigmatism were against-the-rule. They found that such errors were lower with the Baylor nomogram and lowest when the Barrett toric calculator was used. The most accurate results were attained with the optical low-coherence reflectomet y and the Barrett toric calculator. With these, 97.1% of eyes were within 0.75 D and 75% were within 0.50 D. The conclusion reached was that with the aid of appropriate measuring devices and methods it is possible to improve prediction of astigmatism outcomes for patients receiving toric IOLs.
