11 EW NEWS & OPINION June 2015 T he Combined Ophthalmic Symposium (COS)—pre- sented by ASCRS, ASOA and ASORN—is going from the River Walk to the Colorado River, as this must-attend ASCRS•ASOA meeting relocates from San Antonio to Austin on August 21–23. Formerly known as the Ophthalmology Symposium, COS provides education for the entire practice in one weekend at the brand new JW Marriott Austin. Austin consistently ranks as one of America's best cities to visit. In addition to being the "Live Music Capital of the World," visitors will find outstanding dining experiences, sporting events, and outdoor activi- ties. The housing deadline is July 29, so make your reservation today. Registration for COS is open, offering an optional ICD-10 course and the following programs (subject to change): Residents and Fellows: This program is intended for ophthal- mic residents and anterior segment fellows with an interest in improv- ing basic cataract surgical skills. The program chair is Sumitra S. Khandelwal, MD. Program facul- ty includes Preeya K. Gupta, MD; Kendall E. Donaldson, MD; Zaina Al-Mohtaseb, MD; and Christina Weng, MD. Ophthalmologists: This pro- gram is aimed at anterior segment surgeons, comprehensive ophthal- mologists, ophthalmic residents and fellows with an interest in anterior segment care. The program chairs are Douglas D. Koch, MD; Sumitra S. Khandelwal, MD; and Mitchell P. Weikert, MD. Program faculty includes Zaina Al-Mohtaseb, MD; Surendra Basti, MD; Robert J. Cionni, MD; Richard S. Davidson, MD; Kendall E. Donaldson, MD; Preeya K. Gupta, MD; Douglas J. Rhee, MD; Barry S. Seibel, MD; Steven D. Void, MD; and Christina Wend, MD. ASCRS designates this live activity for a maximum of 18.5 AMA PRA Category 1 Credits. All CME activities approved for AMA PRA Category 1 Credit are valid for recognition by the European Accreditation Council for Continu- ing Medical Education (EACCME). Physicians not licensed in the U.S. who participate in this CME activity are eligible for AMA PRA Category 1 Credit. ASOA Practice Management: Ophthalmologists, practice admin- istrators, ophthalmic nurses and technicians, and optometrists will benefit from this program, which covers a range of topics from ICD-10 compliance to social media market- ing tools. The program qualifies for COE Category A credits. Optometrists: This educational activity is intended for anterior seg- ment surgeons, comprehensive oph- thalmologists, ophthalmic residents and fellows, practice administrators, ophthalmic technicians and nurses, and optometrists with an interest in anterior segment care. The program chairs are Ahmad Fahmy, OD, FAAO, and Walter O. Whitley, OD, MBA. Nurses and Technicians: This comprehensive program for oph- thalmic nurses and technicians will include courses on the latest advanc- es in biometry and IOL technology for the refractive cataract surgery patient, information on the medical and surgical treatment of glaucoma, issues in caring for the aging patient, and much more. For nursing, this course will be available for 11.75 Nurse Contact Hours. For JCAHPO, this course will be submitted for consideration of 10.75 JCAHPO credits. Exhibitors and Sponsors: This meeting also provides an excellent opportunity for exhibiting or spon- soring companies to network with all facets of an ophthalmic practice in a relaxed and intimate setting. The venue allows for close proxim- ity of exhibits and general sessions, ensuring more interaction between exhibitors, sponsors, attendees, and faculty during breaks. The mix of programming, exhibits, and social interaction guarantees extensive exposure to the meeting attendees. Interested exhibitors and sponsors should contact Jamie Barbera, ex- hibits manager, or Jeff Brownstein, director of sales. More information on the meet- ing can be found at COS.ascrs.org.

Association between corneal hysteresis and the magnitude of intraocular pressure decrease after cataract surgery Madhvi Deol, BA, Joshua R. Ehrlich, MD, MPH, Mitsugu Shimmyo, MD, Nathan M. Radcliffe, MD In this retrospective study, investigators considered the interplay between the change in intraocular pressure and baseline corneal hysteresis in 39 consecutive non-glaucoma patients who underwent phacoemulsification. For all of these cases a posterior chamber lens was implanted. While preoperatively patients had a mean IOP of 14.8, by 2 to 4 months postoperatively this had dropped to just 11.9 mm Hg, and at 10 to 12 months postoperatively was at a mean of 12.6 mm Hg. Investigators determined that at the 2- to 4-month mark the baseline corneal hysteresis was not predictive of IOP reduction. However, for IOP reduction at the 10- to 12-month mark there was a statistical association between the magni- tude of IOP reduction and the baseline corneal hysteresis, when patient age was controlled for. Meanwhile, no such connection was found to baseline central corneal thickness. Investigators concluded that following cataract removal there was a larger magnitude of IOP reduction in cases involving a low baseline corneal hysteresis. Refractive outcomes of Descemet's membrane endothelial keratoplasty triple procedures (combined with cataract surgery) Evan D. Schoenberg, MD, Francis W. Price Jr., MD, Jalee Miller, BS, Yuri McKee, MD, Marianne O. Price, PhD How do patients with Fuchs' endothelial dystrophy and cataract fare visually when undergoing triple Descemet's membrane endothelial keratoplasty? Investi- gators in this retrospective case series set out to determine this by evaluating out- comes from 108 sequential triple DMEK procedures. They found that the median corrected distance visual acuity was 20/20 at the mean follow-up of 11.9 months, with 45% of patients gaining 3 or more lines of corrected distance acuity. When it came to uncorrected distance visual acuity the median result was 20/40. Inves- tigators found that while refractive astigmatism was not significantly changed by aspheric intraocular lenses, toric lenses did have an effect. Investigators also found that keratometry by partial coherence interferometry changed following the procedure, while the anterior curvature measurements taken by Scheimpflug imaging did not. The triple DMEK procedure was determined to safely attain excellent corrected distance visual acuity. Investigators noted that using measure- ments averaging curvature might result in underreporting of significant refractive deviations since Fuchs' dystrophy induces changes mostly in the central cornea. To reduce the number of eyes left hyperopic they recommend aiming for a –0.75 to –1 D result. Incidence of corneal infections after laser in situ keratomileusis and surface ablation when moxifloxacin and tobramycin are used as postoperative treatment Julio Ortega-Usobiaga, MD, PhD, Fernando Llovet-Osuna, MD, PhD, Mohammad Reza Djodeyre, MD, PhD, Andrea Llovet-Rausell, MD, Jaime Beltran, MD, Julio Baviera, MD Investigators launched a retrospective review to determine what happens to infectious keratitis incidence when topical moxifloxacin is added to a tobramy- cin postoperative prophylaxis. After reviewing the charts of 55,355 patients who underwent LASIK or surface ablation, they identified 10 eyes with post-LASIK infectious keratitis and another 11 with post-surface ablation infectious keratitis. Investigators determined that in 36.36% of cases infections occurred early after surface ablation, which was also true for 40% of LASIK cases. When it came to cultures these were positive in 2 cases after surface ablation. In 70% of post-LASIK infectious cases the final corrected distance visual acuity was 20/20 or better, as well as for 63.64% of surface ablation cases. All cases resulted in 20/40 vision or better. Data on this cohort was also compared to previously published results from 221,437 eyes that just received postoperative tobramycin. Investigators found that after LASIK when the moxifloxacin regimen was used there was a de- crease from 0.025% of cases to 0.011%, while after surface ablation this dropped from 0.200% to 0.066%. Investigators concluded that cases of infectious keratitis occurred less often after LASIK than surface ablation. Also, when the combina- tion of tobramycin and moxifloxacin was used there was a lower frequency of mainly early-onset keratitis than with tobramycin alone.
