FROM THE 5th ANNUAL CEDARS/ASPENS met at the iconic Fontainebleau Hotel in Miami Beach, Florida, during the Society's 5th Annual I•C•E Conference. The 4-day event, which spanned from December 10 to 13, 2015, was attended by CEDARS/ASPENS members and ophthalmic industry exhibitors and attendees. The organization's goals of innovation, collaboration, and education were strongly demonstrated throughout the Conference. The daily academic sessions concentrated on presentations, followed by vigorous and sometimes controversial panel discussions, the topics of which included Challenging Cases and Controversies in Cataract, Refractive, and Cornea; External Disease: Hot Topics Case Debates; Glaucoma; The Business of Dry Eye; and Practice Management Game Changers. The presenters discussed and debated various "This unique and intimate format brought together leaders from approaches to challenging patient problems and the pros and cons of different surgical interventions, among other things.

Kenneth Beckman, MD, Clinical Assistant Professor of Ophthalmology at The Ohio State University and Director of Corneal Services at Comprehensive EyeCare of Central Ohio in Westerville, Ohio, also emphasized the importance of the interaction of industry and surgeons: "Our Annual Conference facilitates expansion and dissemination of knowledge among peers and promotes excellent patient care through the give-and-take of experiences."

COMMITMENT TO EYE CARE
Strong ophthalmic pipeline, proposed Pfizer link, will enhance
customer and physician support
Active engagement with leading ophthalmic surgeons will play a critical role as global pharmaceutical company Allergan strengthens its commitment to eye care, asserts Dave LeCause, Vice President for US Eye Care Sales and Marketing. Following the firm's successful combination with Actavis last March, Allergan has 17 eye care programs in middle- to late-stage development. Among these are new pharmaceuticals and devices targeting dry eye, glaucoma, and retinal diseases.
"Allergan has a long and robust history of innovation that has produced a market-leading eye care portfolio. We have introduced entirely new drug categories like alpha agonists in glaucoma and RESTASIS® in dry eye. But we would not have had any success without the great partnerships we have built with patients and doctors in the eye care community," LeCause says.
Contracting with insurance plans and formularies so that the right Working closely with practicing clinicians and thought leaders eye care is available at a reasonable out-of-pocket cost is one element. is part of Allergan's "Open Science" development model, Another is targeted patient support, such as the RESTASIS® My which also includes in-house R&D and outreach to academic Tears, My Rewards® Program. It features money-saving refills, a customer researchers, venture-capital-backed entrepreneurs and startups, service hotline, and an iPhone® app with twice-daily dosing reminders. LeCause explains. "We are constantly evaluating new options. "Making sure patients get the right support so they can continue to This multidimensional approach gives us the flexibility to benefit over time is a real priority," LeCause says.

training in eye disease basics and practical tools, such as assessment Over the next few years Allergan will focus primarily on dry eye, questionnaires and a Smartphone app that helps answer patient glaucoma, and retina, according to LeCause. He expects 5 or 6 questions. TechAlliance also supports patients with downloadable new dry eye products, including RESTASIS® in a preservative- coupons, videos on taking eye drops, and medication diaries. "It free, multidose bottle. "This offers convenience to patients and will make a strong dry eye therapy even more attractive." enhances service at the point of care.

For glaucoma, Allergan plans to build on its successful ALPHAGAN®, LUMIGAN®, and COMBIGAN® eye drops "Allergan's proposed combination with biopharmaceutical giant with extended-release drug delivery technologies and the recently Pfizer is the next step," LeCause adds. "It will create an extremely acquired AqueSys XEN® Gel Stent.

A new sponsor of the CEDARS/ASPEN Society and a new entrant in ophthalmics, Shire is a leading global biotech company headquartered in Lexington, MA, and Zug, Switzerland. The company has a 30-year history of developing innovative medicines for patients with rare diseases and specialty conditions, in areas including neuroscience, gastrointestinal medicine, and internal medicine. Shire's CEO, Flemming Ornskov, MD, hinted at the rationale for entering into ophthalmics in a recent interview – "We like small and specialized spaces and we count ophthalmology to that," Ornskov said. "We think there is a significant innovation vacuum for someone who truly focuses on the patient aspects of ophthalmology." When entering a new therapeutic area, Ornskov has said that Shire's goal is to "become one of the top three companies in that arena," achieved primarily by bringing innovation to areas of unmet need. Based on that statement, perhaps it's not surprising that in just over two years, Shire has already made enormous progress in retinitis pigmentosa, and infectious conjunctivitis. Now the company achieving that goal by focusing on key areas: is focused on moving these assets forward, always focused on the unmet medical needs of patients with ophthalmic diseases.
