E W NEWS & OPINION 1 1 I qbal "Ike" K. Ahmed, MD, will be awarded the Binkhorst Medal and will present the prestigious Binkhorst Lecture during the Opening General Session of the ASCRS•ASOA Symposium & Congress in Boston on April 26. His lecture, titled "Microinva- sive Glaucoma Surgery: An Idea Whose Time Has Come," will explore the promise of this new, potentially disruptive technology and its increasing role in the treatment paradigm for glaucoma. Since 1975, the Binkhorst Medal has been awarded to the world's most prominent ophthalmologists whose careers have made significant contributions to the science and practice of ophthalmology. During his distinguished career, Dr. Ahmed's work has established him as a fore- most leader in the field of ophthal- mology and a primary force in the surgical management of glaucoma, complex cataract, and intraocular lens complications. Dr. Ahmed is currently assistant professor at the University of Toronto and clinical assistant professor at the University of Utah. He is the research director at the Kensington Eye Institute and the director of the Glaucoma and Advanced Anterior Segment Surgery (GAASS) fellowship, both at the University of Toronto. Dr. Ahmed is February 2014 Changes in choroidal thickness after cataract surgery H ideharu Ohsugi, MD, Yasushi Ikuno, MD, Zaigen Ohara, MD, Hitoshi Imamura, MD, Shunsuke Nakakura, MD, Shinji Matsuba, MD, Yoshitake Kato, MD, Hitoshi Tabuchi, MD In this prospective study of 100 eyes, investigators considered how choroidal thickness was affected by cataract surgery in patients without other eye pathology. They determined that at the three-week, three- month, and six-month marks, the postoperative IOP significantly de- creased. Meanwhile, throughout the follow-up period they found that at the foveal and inferior regions the choroidal thickness significantly in- c reased after cataract surgery. This was also increased at three days, one week, and six months for the nasal region, at one week for the temporal region, and at six months for the superior region. Investigators found that when these changes occurred early after surgery they were nega- tively correlated with those in IOP. Later changes in choroidal thickness in all regions were negatively correlated with the axial length. Investiga- tors determined that changes in choroidal thickness were caused by cataract surgery. When evaluating these changes, they concluded that both axial length and IOP fluctuations were of critical importance. Safety, efficacy, and predictability of LASIK in thin corneas Minoru Tomita, MD, Miyuki Watabe, PhD, Mariko Mita, MD, George O. Waring IV, MD Do thin but otherwise normal corneas negatively impact long-term out- comes of LASIK? That's what investigators here wanted to determine. In this retrospective, randomized, comparative study, "thin" corneas of less than 500 microns but with normal topography were compared to those of controls with corneal thickness of 500 microns or greater. Investiga- tors found that the thin cornea group showed a significant difference in visual and refractive outcomes between the three-month postoperative mark and the last checkup. However, at the last checkup, visual, refrac- tive, or topographic outcomes were not significantly different between the two groups. The conclusion reached was that there was similar long- term stability in the two groups, with LASIK in those with thin corneas considered safe and effective. Review/update: Indications and contraindications for multifocal IOL implantation Rosa Braga-Mele, MD, David Chang, MD, Steven Dewey, MD, Gary Foster, MD, Bonnie An Henderson, MD, Warren Hill, MD, Richard Hoffman, MD, Brian Little, MD, Nicholas Mamalis, MD, Thomas Oetting, MD, Donald Serafano, MD, Audrey Talley-Rostov, MD, Abhay Vasavada, MD, Sonia Yoo, MD, for the ASCRS Cataract Clinical Committee Determining which multifocal IOLs to select for use in the United States and what the best clinical practice for this is currently was the focus of investigators here. The update highlighted patient selection standards, important preoperative diagnostic tests, and included advice for coun- seling patients, as well as for managing expectations. This review also included recommendations for handling intraoperative difficulties and considered what to do when implanting multifocal IOLs in cases involv- ing patients with underlying ocular challenges. The update ultimately addressed how to approach those who may be unhappy with the multifocal IOL that has been implanted.

Ahmed, MD, to receive ASCRS Binkhorst Medal ASCRS update continued on page 12 Iqbal "Ike" K. Ahmed, MD also head of the ophthalmology d ivision at Trillium Health Partners, Mississauga, Ontario. Dr. Ahmed has earned a world- wide reputation for his groundbreak- ing work in the diagnosis and surgical treatment of highly com- plex eye diseases, including glau- coma. Dr. Ahmed has been a leader in novel treatments for glaucoma, c ataract, and lens implant surgery. He has done pioneering work in innovative glaucoma surgery, developing and coining the term "microinvasive glaucoma surgery (MIGS)" as a new genre of surgical approaches and devices. In 2010, Dr. Ahmed was selected as one of Canada's "Top 40 Under 40"— a prestigious national award recognizing significant achieve- ments at a young age. Dr. Ahmed has received numer- ous research grants to study glau- coma medications, glaucoma laser and surgical devices/techniques, angle closure glaucoma, anterior segment and retinal/optic nerve im- aging in glaucoma, cataract surgical techniques and devices, and intraocular lens designs. Dr. Ahmed has designed microsurgical instru- mentation, devices, implants, and techniques for the management of the dislocated cataract, iris recon- struction, and glaucoma. In addition to holding many educational direc- torships and serving on the editorial boards of several scientific journals, Dr. Ahmed has published more than 120 peer-reviewed articles and book chapters, given more than 600 scien- tific presentations, and delivered 28 visiting professor's lectures around the world. Registration for the ASCRS•ASOA Symposium & Congress, which will be held in Boston in April 25–29, is now open.
