UPDATE 12 In the journal Optimization of femtosecond lasers using porcine and human donor corneas prior to in vivo use Jenna Stoddard, BS, Athanasios Marneris, DO, Matthew Borr, DO, Michael Keil, DO This study aimed to optimize femtosecond settings with the LDV Z4 laser (Ziemer, Port, Switzerland) for creation of intrastromal corneal pockets to allow for the implantation of the KAMRA small aperture cor- neal inlay (CorneaGen, Seattle). Deeper LASIK flap creation needed for the Raindrop corneal inlay (ReVision Optics) was also studied. Initially, porcine corneas were used to create a 12-mm pocket and tunnel with 105% energy, followed by use of human donor corneas where a 13-mm pocket and tunnel were made with 110% femtosecond energy. Then 14-mm pockets were made in vivo for the KAMRA inlay using 110% energy. For the LASIK flaps, investigators determined that whether these were 110 or 180 micrometers, the same settings could be used with- out adjustments. Investigators concluded that prior to creating in vivo corneal pockets, further optimization was needed from those used in the initial porcine corneas. When it came to the Raindrop inlay, however, the deeper corneal flaps made here required no further optimization. Intracameral moxifloxacin for endophthalmitis prophylaxis after cataract surgery: Cost-effectiveness analysis Ella Leung, MD, Allister Gibbons, MD, Timothy Stout, MD, Douglas Koch, MD In this study investigators considered how endophthalmitis prophylax- is with intracameral moxifloxacin during cataract surgery along with perioperative antibiotics compared to the traditional topical antibiotic approach in terms of cost. They determined that by using a 500-mi- crogram intracameral injection of moxifloxacin there was a $20 cost savings from a societal perspective compared with traditional pro- phylaxis in the case of a 73-year-old man undergoing his first cataract surgery. This $20 amount fell within the $50 threshold of societal willingness-to-pay. The incremental cost-utility ratios of $8,275/quali- ty-adjusted life years was also found to be cost effective in terms of the healthcare sector perspective. There was cost savings found in cases of posterior capsule tears with the intracameral moxifloxacin approach. In- vestigators concluded that the intracameral approach was cost effective and had cost savings for society versus use of topical antibiotics alone. However, from a healthcare sector perspective, while the $20 intraca- meral moxifloxacin was cost effective, it did not have cost savings. In terms of improving quality of life years, the intracameral approach was deemed to have greater effectiveness than the topical approach. Medical and surgical management of the small pupil during cataract surgery Saba Al-Hashimi, MD, Kendall Donaldson, MD, Richard Davidson, MD, Deepinder Dhaliwal, MD, Mitchell Jackson, MD, Jeremy Kieval, MD, Larry Patterson, MD, Karl Stonecipher, MD, David Hamilton, MD, for the ASCRS Refractive Cataract Surgery Subcommittee While there are steps that can be taken to reduce the chances of intra- operative miosis during cataract surgery, this remains something with which even the most experienced surgeons continue to contend. To maximize patient outcomes and satisfaction postoperatively, the authors describe preoperative and intraoperative factors that can improve ease and safety when dealing with cataract cases involving small pupils. They highlight the risk factors associated with intraoperative miosis and the subsequent complications that can occur, and consider management strategies before, during, and after cataract surgery with small pupils. August 2018 by Denise Monasterio ASCRS Marketing and Communications Manager ASCRS educator spotlight: Li Wang, MD, PhD Li Wang, MD, PhD A SCRS is a member-led or- ganization, and much of the education, informa- tion, and other offerings are developed by anterior segment specialists for anterior seg- ment specialists. The success of the organization is highly impacted by the continued dedication and volunteerism of the individuals who serve as educators. Every month, we feature one of these member volunteers. We will introduce individuals who have contributed to the society's outstanding education, helping members strengthen their skills and sharpen their expertise, and provide better care to patients. This month's spotlight member is Li Wang, MD, PhD. Dr. Wang is one of the three authors of the Post-Refractive IOL Calculator, along with Douglas Koch, MD, and Warren Hill, MD, and is also a member of the ASCRS IOL Calculation Subcommittee. She is pivotal in the maintenance and continued accuracy of the Post-Re- fractive IOL Calculator, available on the ASCRS website. Dr. Wang works tirelessly to ensure that this calcu- lator is up to date, and works with staff to answer questions about the formulas and difficult calculations. Outside of the ASCRS IOL Cal- culation Subcommittee, Dr. Wang serves as a member of the editorial board for the Journal of Cataract and Refractive Surgery (JCRS). She is a key member of the board due to her expertise in IOL calculations and clinical optics. She routinely serves as a presenter and course instructor at ASCRS•ASOA Annual Meetings. Dr. Wang is associate professor of ophthalmology, Cullen Eye Insti- tute at Baylor College of Medicine in Houston. Dr. Wang received her medical degree from Shanxi Medical College in Taiyuan, Shanxi Prov- ince, China. She completed both an internship and residency at the First Affiliated Hospital of Shanxi Medical College. She earned her PhD from the Ruprecht-Karls-Universität in Heidelberg, Germany, and complet- ed a fellowship at Baylor College of Medicine. Dr. Wang has co-authored more than 50 peer-reviewed publications and numerous chapters and articles, including several seminal papers fo- cused on IOL power calculation and ocular aberrations. She is an active member of ASCRS, the Association for Research in Vision and Oph- thalmology, and the International Society of Refractive Surgery. During her off hours, Dr. Wang enjoys spending time with her hus- band, Jianzhong Ma, PhD, who is a physicist/statistician, and their son, Jack, a fourth-year medical student who is applying for residency train- ing in ophthalmology.
