Eyeworld

UPDATE 15 demand for services continues to grow. Help continue to bring sight to those in need by visiting the Give Sight Interactive Wall in the Exhibit Hall. The wall will allow attendees to learn more about the people the Foundation serves and directly support a patient in need. Attendees can give sight now on their Annual Meeting registration at annualmeeting.ascrs.org. Instructional course on international humanitarian eye care On April 17, an instructional course will be offered by members of the ASCRS Foundation's International Committee that will present work being done by organizations dedicat- ed to fighting curable world blind- ness in Africa. Various perspectives will be discussed, including large- scale eye camps versus teaching programs, MSICS versus phaco, and challenges of subspecialty surgery. Through discussion, participants will gain insight into preparing for surgical missions, including trav- el and health concerns, necessary surgical skills, and setting reasonable expectations. Become an Operation Sight volunteer Since its beginning in 2014, the Foundation's Operation Sight network of volunteer surgeons has provided more than 1,800 free cat- aract surgeries for needy American patients living in their own commu- nities. Almost 300 ASCRS members have generously volunteered their time and expertise. Visit the Foun- dation Give Sight Interactive Wall to learn more about Operation Sight and to sign up to become a volun- teer. There are 200 patients currently awaiting a volunteer surgeon match. Watch Operation Sight in action through the lens of fellow ASCRS members by viewing the film detail- ing their experience planning the First Annual Cataractathon in Mem- phis, Tennessee. The film by Emily Graves, MD, Jason Jensen, MD, and Brian Fowler, MD, can be viewed onsite at the Annual Meeting. EW Contact information Zundel: nzundel@ascrs.org Find out more about the ASCRS Foundation at the 2018 ASCRS•ASOA Annual Meeting T hanks to volunteer sur- geons, donors, corporate supporters, and nonprof- it partners, the ASCRS Foundation was able to give sight to a record number of individuals in 2017. The Opera- tion Sight cataract program helped provide 1,000 free surgeries to needy American patients, and the Robert Sinskey Eye Institute in Addis Ababa, Ethiopia served a record 24,000 patients. Through partnerships with six like-minded organizations, the Foundation is working to address the root cause of global cataract blindness: the drastic shortage of eye surgeons in developing countries. Help maintain this momentum through 2018 and beyond by partic- ipating in a Foundation activity at the ASCRS•ASOA Annual Meeting in Washington, D.C. Run for Sight Join the ASCRS Foundation on April 15 at 6:30 a.m. for the 6th Annual Run for Sight sponsored by Johnson & Johnson Vision (Santa Ana, California). Featuring a 5K run and a 1-mile walk, this healthy lifestyle event will raise money for the ASCRS Foundation's ongoing charitable work while also helping to burn off some of those conference calories. All race proceeds go to sup- port the Foundation's humanitarian cataract surgery programs in the U.S. and Ethiopia. This year's Run for Sight will start and finish on Pennsylvania Avenue with sunrise views over the U.S. Capitol at what could be the height of cherry blossom season. All participants receive a race T-shirt and finisher's medal. Register online (www.tracs.net/ascrs5k) or onsite at the Foundation booth. Give Sight Interactive Wall At the 2017 annual meeting, 500 ASCRS and ASOA members helped give almost $100,000 to the Foun- dation's humanitarian eye care pro- grams. That is how it served more than 25,000 patients last year. But by Natalie Zundel ASCRS Foundation Development Director #GiveSight while you learn in Washington, D.C. In the journal Transepithelial corneal crosslinking for keratoconus Peter Hersh, MD, Michael Lai, BS, John Gelles, OD, Sebastian Lesniak, MD In this prospective case series, investigators evaluated how those with kerato- conus fared using a transepithelial corneal crosslinking technique. The 82 eyes included here underwent transepithelial crosslinking with riboflavin 0.1% and topical anesthetic containing benzalkonium chloride. The treatment was admin- istered either every 1 minute or every 2 minutes in conjunction with exposure to ultraviolet-A at 3 mW/cm 2 depending on which group the patient was random- ized to. At the 1-year mark, investigators determined that there was a significant 0.45 D drop in maximum K values. There was a 0.7-line improvement in uncor- rected distance visual acuity and a 0.2-line improvement in corrected distance visual acuity. When it came to significant improvements in maximum K and uncorrected distance visual acuity, this only occurred in those who received the treatment every minute. The conclusion reached was that procedure outcomes may be improved with use of increased riboflavin dosing. However, investigators stressed that further comparison of different transepithelial approaches is needed to determine the relative pros and cons of each. Prospective nonrandomized comparative study of three types of intracorneal implants for management of central keratoconus Mohamed Omar Yousif, MD, Azza Mohamed Ahmed Said, MD The aim of this prospective case series, involving 73 eyes, was to compare the outcomes of three different devices used in keratoconus cases: KERATACx 160-de- gree two symmetrical ring segments (Imperial Medical Technologies, Cartersville, Georgia), KERATACx 320-degree, and the continuous intracorneal ring (MyoRing, Dioptex, Linz, Austria). Investigators found that there was a significant improve- ment postoperatively in uncorrected and corrected distance visual acuity, spheri- cal equivalent, corneal and refractive astigmatisms, K readings and Q value for all three devices. Patients who received the KERATACx 320-degree segments showed a significant increase in both uncorrected and corrected distance acuity com- pared with those who received the 160-degree ring segments. When it came to reduction in spherical equivalence, the 320-degree segment and the continuous intracorneal ring proved most effective. Investigators concluded that while all of the devices were effective, when it came to uncorrected distance visual acuity and spherical equivalence, the 320-degree segment and the continuous intracorneal ring provided the most improvement. Outcomes of cataract surgery in eyes with ocular melanoma treated with iodine-125 brachytherapy Tahir Kansu Bozkurt, MD, Qiongyan Tang, MD, Lev Grunstein, MD, Tara McCannel, MD, Bradley Straatsma, MD, Kevin Miller, MD How do eyes with a history of iodine-125 brachytherapy for ocular melanoma fare when undergoing cataract surgery? In a retrospective case series that includ- ed 32 eyes of 32 patients, investigators considered this. There was a history of preoperative radiation retinopathy in 56.3% of eyes. Investigators determined that 68.8% of eyes showed a two-line or better improvement between postopera- tive week 2 and 4. However, radiation maculopathy occurred in seven of 10 eyes and these showed no improvement. By the final follow up, corrected distance visual acuity had improved in 40.6% of cases, while 28.1% had lost two lines or more of acuity and 31.3% had acuity that remained the same. Investigators found that nine out of 15 eyes that had lost corrected distance visual acuity gains had either new cases of maculopathy or worsening ones. The conclusion reached was that while cataract surgery for those who have undergone iodine-125 brachytherapy initially improved corrected distance visual acuity postoperatively, such gains were later often lost. Investigators attributed this vision loss in most cases to the progression of radiation maculopathy. EW March 2018 Insightful news from the ASCRS Foundation
