June 2013 2013 ASCRS•ASOA Symposium & Congress Best Papers of Session The ASCRS•ASOA Symposium & Congress provides a stage for anterior segment innovators to share novel tools, techniques, and technologies. From smartphones to surveys to UBM to pupillometry, our colleagues give us novel uses of current technology to improve patient care. Here, we showcase four anterior segment papers presented at the 2013 ASCRS•ASOA Symposium & Congress in San Francisco, all of which earned the designation of Best Paper of Session. Christian Hester, MD, helps us understand how we might use our smartphones to better assess and follow an impaired ocular surface. Daniel Chang, MD, shares the results of his patient survey, which suggests that patient satisfaction involves more than the sum of visual acuities. Rita Mencucci, MD, shows how pupillometry can help us better understand the pathogenesis of IFIS. And Lajja Shastri, MS, describes how UBM can aid in Cionni ring treatment of subluxated pediatric IOLs. Saras Ramanathan, MD, cataract editorial board member iPod slit lamp videography as a tool to evaluate ocular surface disease in dry eye Christian Hester, MD, Mitchell P. Weikert, MD, Stephen C. Pflugfelder, MD The purpose of the study was to evaluate iPod slit lamp videography as a tool to document and grade ocular surface disease. Patients with dry eye were examined with a HaagStreit (Koniz, Switzerland) slit lamp and yellow barrier filter. The severity of corneal fluorescein staining, conjunctival lissamine green staining, and tear breakup time (TBUT) were graded by the slit lamp examiner (CCH). Slit lamp videos were then immediately obtained using an iPod Touch 5th Generation, ProCamera iPhone app, EyePhotoDoc iPod slit lamp adapter, and yellow barrier filter. The videos were graded in a masked fashion (SCP) and compared to visual grading (CCH). Of the 14 eyes that were enrolled in the study, no statistically significant differences were found between iPod videography grading scores and slit examination grading scores (P>0.05). The authors concluded that iPod videography grading appears to be a reliable method for documenting dry eye findings and may serve as a standardized means for grading dry eye findings in multicenter research trials. Videos may also improve the ability to detect pre- and post-treatment differences in these dry eye parameters. Intermediate and near visual acuity in photopic and mesopic lighting conditions with an aspheric diffractive multifocal one-piece IOL Daniel H. Chang, MD The purpose of this paper was to simulate real-world performance of a diffractive multifocal IOL by measuring binocular intermediate and near visual acuity under photopic and mesopic lighting conditions. At a single prospective study visit, 32 eyes with previous implantation of Tecnis Multifocal one-piece IOLs (ZMB00, Abbott Medical Optics, Santa Ana, Calif.) were evaluated at 9.9±3.9 months postoperative. Mean spherical equivalent was +0.00±0.29 D with 0.20±0.24 D cylinder. At distance, UCVA was 20/19 (88% 20/20 or better). At intermediate, UCVA was 20/27 (94% 20/40 or better) under photopic conditions and 20/42 (94% 20/63 or better) under mesopic conditions. At near, UCVA was 20/21 (94% 20/25 or better) under photopic conditions and 20/28 (94% 20/40 or better) under mesopic conditions. All patients were either "very satisfied" or "satisfied" with their overall vision without glasses. Alpha blockers and IFIS: Correlation of functional and anatomical data Rita Mencucci, MD, Iacopo Paladini, MD, Roberto Volpe, MD, Mattia Pasti, MD, Andrea Minervini, MD, Ugo Menchini, MD Intraoperative floppy iris syndrome (IFIS) is an intraoperative syndrome generally correlated with the use of alpha-blockers, and its pathophysiology is still not clear. The authors studied two different groups of patients trying to better understand IFIS pathogenetic mechanisms. The first group (20 patients) was evaluated from the beginning of therapy with alpha-blockers with static and dynamic pupillometry. After a sixmonth follow-up in all treated continued on page 20
