July 2013 December 2011 May 2013 EW NEWS & OPINION 9 ASCRS update Valuable content from annual meeting available at ASCRS MediaCenter In the journal … by Cindy Sebrell ASCRS•ASOA Director of Marketing and Communications July 2013 Povidone-iodine 1.0%, 5.0%, and 10.0% as preoperative prophylaxis before cataract surgery Bing Li, MD, Martin M. Nentwich, MD, Larissa E. Hoffmann, BS, Christos Haritoglou, MD, Daniel Kook, MD, Anselm Kampik, MD, Minjie Sheng, MD, Herminia Miño de Kaspar, PhD Investigators in this randomized clinical trial of 271 patients considered how the preoperative conjunctival bacterial load was affected by changing the concentration of povidone-iodine used in conjunction with topical levofloxacin 0.3%. Preoperatively all patients were given topical levofloxacin 0.3%. Patients randomized to group 1 were also given 1% povidone-iodine, those in group 2 received 5% povidone-iodine, and those in group 3 the highest concentration at 10%. While there were no significant differences in positive cultures found between the no-surgery control eyes, significant differences were found in bacterial-load reduction between those in group 3 and the other two groups. The most commonly found organism here was coagulasenegative Staphylococcus. Investigators concluded that for preoperatively reducing conjunctival bacterial load, 10% povidone-iodine was more effective than either the 1% or 5% concentrations. Evaluation of LASIK in U.S. naval aviators David J. Tanzer, MD, Tyson Brunstetter, OD, PhD, Richard Zeber, OD, Elizabeth Hofmeister, MD, Sandor Kaupp, MS, Neil Kelly, PhD, Myah Mirzaoff, William Sray, MD, Mitch Brown, OD, Steven Schallhorn, MD How well do naval aviators fare after undergoing femtosecond-assisted wavefront-guided LASIK? That's what investigators in a recent prospective non-comparative study wanted to determine. In the twosite study, patients slated to undergo femtosecond-assisted, wavefrontguided LASIK were divided into one of three groups—those with preoperative myopia, mixed astigmatism, or hyperopia. At all postoperative visits,investigators found that 98.3% of myopic patients and those with mixed astigmatism attained uncorrected distance visual acuity of 20/20 or better, as did 95.7% of hyperopic eyes at the threemonth postoperative mark. Those in the myopic group saw a gain in corrected distance acuity of 39.2%, those with mixed astigmatism of 41.1%, and those with hyperopia of 30.4%. In two myopic eyes following surgery there was a loss of two lines of corrected distance acuity. At the three-month mark when asked if they believed that LASIK had helped their effectiveness, 95.9% agreed and nearly all, 99.6%, claimed that for others they would recommend the same treatment. The conclusion reached here was that for naval aviators who quickly want to return to their flight duties, femtosecond-assisted wavefrontguided LASIK is a safe, effective option. Update/review: Contrast sensitivity Jesse Richman, MD, George L. Spaeth, MD, Barbara Wirostko, MD When it comes to pinpointing ocular diseases, practitioners rely heavily on contrast sensitivity testing. Currently, as an adjunct to standard visual acuity measurements, investigators noted that determining the peak of contrast sensitivity function can provide useful clinical information. In addition to considering the basics of such measurements, they described and compared present contrast sensitivity tests, bearing in mind the pros and cons of each of these. T he 2013 ASCRS•ASOA Symposium & Congress in San Francisco was a phenomenal experience for many members. With the city providing a spectacular backdrop, nearly 5,000 medical doctors (a record number!) attended courses, symposia, papers, and special events presented by more than 1,200 speakers. Even for those who filled their meeting itinerary from sun up to sun down, it was impossible to see and hear everything that the event had to offer. Now, and in the coming months, ASCRS will be working hard to ensure that much of the valuable content captured at the meeting will be available online and delivered directly to your inbox and smartphone. Here are a few ways that you can revisit or discover some of the high-quality clinical education that ASCRS has recently provided for the anterior segment surgeon. New, enhanced ASCRS MediaCenter brings top surgical videos online With the launch of its newer, more robust MediaCenter, ASCRS is mak- ing a library of clinical content available free of charge. Featuring a new, sleek interface, intelligent navigation tools, and a streamlined, smartphone-friendly viewing experience, the new platform hosts hundreds of videos with more clinical content being added daily. Viewers can search videos, courses, symposia, general session presentations, and other material by topic, including intraocular (cataract and refractive), glaucoma, cornea, and keratorefractive surgeries. Check back often at mediacenter.ascrs.org as more clinical educational material will be made available regularly. continued on page 10 PLAN AHEAD FOR NEXT YEAR YEAR HOUSI NG NOW OPE N HOUSING IS NOW OPEN www.WinterUpdate.org www.WinterUpdate.org 2014 2014 APRIL 25–29 APRIL 25–29 BOSTON www.AS C R S.org www.ASCRS.org
