11 EW NEWS & OPINION Headline byline goes here plus fade February 2016 M ark your calendar for Friday, May 6, when the 2016 ASCRS•ASOA Symposium & Con- gress kicks off with pre-meeting programming that will increase your knowledge and enhance your annual meeting ex- perience. In addition to Cornea Day and ASCRS Glaucoma Day, Friday is home to ASOA Workshops and, new this year, Technicians & Nurses (T&N) Tech Talks—all of which offer the high standard of content and quality that attendees have come to expect. The ASCRS•ASOA Sympo- sium & Congress will be held May 6–10 in New Orleans. Cornea Day Are you a practicing ophthalmol- ogist with an interest in compre- hensive ophthalmology, anterior segment surgery, or corneal disease? If so, then Cornea Day should be on your annual meeting schedule. Sponsored by the ASCRS Cornea Clinical Committee and the Cornea Society, this 1-day symposium offers an overview of refractive surgery, as well as corneal issues in cataract sur- gery. The dynamic program features lectures, debates, panel discussions, and surgical video reviews from a renowned faculty. The agenda is designed to improve the knowledge base and skill level of those treating today's patient, and Cornea Day is approved for Continuing Medical Education (CME) credit. "We're especially excited about Cornea Day this year," said Chris Rapuano, MD, co-chair of Cornea Day and past president of the Cor- nea Society. "We tried very hard to create a program that has something for everyone—from the comprehen- sive ophthalmologist to the cornea subspecialist. We'll have challenging case presentations, surgical video pearls, debates and talks on topics including ocular surface disease, all forms of keratoplasty, corneal issues before and after cataract surgery, and the latest in refractive surgery from around the world." Cornea Day requires separate registration. For more details, visit www.CorneaDay.org. In the journal . . . Subclinical keratoconus detection by pattern analysis of corneal and epithelial thickness maps with optical coherence tomography Yan Li, PhD, Winston Chamberlain, MD, PhD, Ou Tan, PhD, Robert Brass, MD, Jack L. Weiss, MD, David Huang, MD, PhD In this observational study, investigators used Fourier-domain optical coherence tomography (OCT) to screen for subclinical keratoconus. Included in the study were 150 eyes of normal subjects, 1 topographi- cally normal eye of a unilateral keratoconus patient, and 50 subclinical keratoconus eyes. Investigators found that for eyes with subclinical ker- atoconus, the pattern of standard deviation (PSD) variables for corneal, epithelial, and stromal thickness maps were all significantly higher than for normal eyes. With the PSD the accuracy was significantly higher than for the pachymetry map-based keratoconus risk score. Investigators concluded that corneal, epithelial, and stromal thicknesses could be mapped using high-resolution Fourier-domain OCT. In particular, using PSD variables, corneal and sublayer thickness changes in subclinical cases could be detected, which might be helpful for discovering early keratoconus. Suction loss during femtosecond laser-assisted small incision lenticule extraction: Incidence and analysis of risk factors Ihab M, Osman, MD, PhD, Ramy Awad, MD, Wei Shi, MS, Mohamed Abou Shousha, MD, PhD In this retrospective study, investigators set out to determine the inci- dence of suction loss during management of myopia or myopic astigma- tism with femtosecond laser-assisted small incision lenticule extraction. Those included here all underwent femtosecond laser-assisted small inci- sion lenticule extraction between August 2010 and April 2014 for the correction of either myopia or myopic astigmatism. Investigators found that 2.1% of the 3,376 eyes developed loss of suction during this study period. Over the course of the study the incidence of such suction loss decreased steadily from 5.06% in 2010 to just 1.84% in 2014, making investigators think that a learning curve was involved. The conclusion reached was that while surgical experience didn't eliminate the risk for suction loss from femtosecond laser-assisted small incision lenticule ex- traction, it did decrease it significantly. Meanwhile, the risk for suction loss was significantly increased when a larger cap diameter was used. Lens epithelial cell growth on the anterior optic of 2 hydrophobic intraocular lens models Tamir Weinberg, MD, Ido Klein, BSc, David Zadok, MD, Monica Huszar, MD, Ayelet Harari, BTec, Nathan Ezov, DVM, Guy Kleinmann, MD The aim in this study was to look at 2 types of hydrophobic intraocular lenses and evaluate how these compared in terms of lens epithelial cell proliferation on the anterior optic. In the study, which included 10 New Zealand white rabbits, an AcrySof IOL (Alcon, Fort Worth, Texas) was implanted in 1 eye after lens removal, dubbed group 1, and a Tecnis IOL (Abbott Medical Optics, Abbott Park, Ill.) in the fellow eye, dubbed group 2. At the end of the 2-week study, investigators found that all of the eyes in group 1 had developed lens epithelial cells, while none of those in group 2 had developed these. Likewise, 8 of those in group 1 had developed areas of proteinaceous matrix deposits next to the edge of the capsulorhexis, while this did not affect any eyes in group 2. Investigators concluded that for those in group 1, both lens epithelial cells and proteinaceous matrix deposits were significantly more abun- dant than for IOLs in group 2. However, when it came to the presence of large cells or general inflammation markers, there was no difference between the IOL types.
