Thursday Singapore 2013 ASCRS•ASOA SYMPOSIUM & CONGRESS, CHICAGO 2012 3 Pearls continued from page 1 tee's approach. "We've taken one structure within the eye and will try to explore everything that we can about it—approaching it from an anatomical point of view, from a PCO prevention point of view, from a management of complications point of view," said Prof. Barrett. "My own talk will focus on the importance of that structure in terms of refractive outcomes, and I'll be surprised if delegates don't walk away from sessions such as this with at least a handful of those precious pearls." Another highlight, the Femtophaco Face-off (Symposium S1, Friday, 14:00 – 15:30hrs, Hall 1, Level 4, Suntec), seeks to provide an exhaustive, "very frank and open discussion" on the pros and cons of different femtosecond cataract machines. Femtosecond cataract has been a hot topic for the last few years; now Prof. Barrett believes that the subject has moved past the novelty phase, with various experts around the region having generated ample information and experience against which it becomes possible to "clinically examine the benefits and weigh them very carefully." Femtosecond cataract surgery will also be featured during the meeting's Live Surgery sessions (Saturday, 8:45 – 11:00hrs, Hall 1, Level 4, Suntec). "We'll have standard surgery as well, so in one live surgery session you'll be able to look at what we're doing and what's coming around the corner," said Prof. Barrett. The first Live Surgery session, sponsored by Bausch + Lomb (Rochester, N.Y.), will be broadcast from the Singapore National Eye Centre. The second, sponsored by Alcon (Fort Worth, Texas/Hünenberg, Switzerland), will be broadcast from Gleneagles Hospital, Singapore. This year's APACRS Film Festival is another highlight, "probably our most successful ever in terms of number of submissions," said Prof. Barrett. "Each year we see the quality of those submissions improving, and with winners of film festivals in other international meetings such as ASCRS and ESCRS often coming from our region, it's not surprising that our own is so well subscribed." At this year's film festival, 82 films will be competing for top prizes to be awarded at the 2013 APACRS Film Festival Awards Ceremony, Friday, 15:30 – 16:30hrs, Hall 1, Level 4, Suntec. The anterior segment event of the year Icing the cake of the scientific program, the addition of satellite meetings in cornea—Cornea Day organized by the Cornea Society and the Asia Cornea Society—and glaucoma—organized by the Asian Angle Closure Glaucoma Club—make this year's annual meeting "not only one of the largest meetings in Singapore, but probably the anterior segment event for Asia-Pacific this year," said Prof. Barrett. This meeting is certainly set to be the biggest APACRS annual meeting to date, with an expected attendance of almost 2,000 participants, with more than 1,850 (more than 1,400 delegates and 450 trade exhibitors) already registered at the time of this writing. It's a fitting return to Singapore, the Society's home, which last hosted the meeting in 2006. "Singapore is one of the most welcoming multicultural environments, with a real sense of people coming together," said Prof. Barrett. "I think that will be reflected at this year's APACRS meeting. "It really is at the crossroads of the Asia-Pacific," he added. "I hope everyone who comes will have a wonderful experience sampling all that Singapore has to offer, all while enjoying one of the most well-structured, most interesting programs in cataract and refractive surgery available anywhere." EWAP ADVERTORIAL Surgical Management of Astigmatism Friday, 12 July at 12:40 hrs Hall 1, Level 4 Moderator A stigmatism remains a major challenge to cataract surgeons seeking to provide their patients with the best outcomes. At tomorrow's lunch symposium on "Surgical Management of Astigmatism" (12:40 – 13:50hrs, Hall 1, Suntec), experts will discuss the various factors influencing the problem and consider the best ways to Han Bor Fam, MD meet the challenge. Surgeons working today have a variety of opFaculty tions, including nomogram-based relaxing incisions, toric IOLs, and laser treatments. Each option has its pros and cons, and the best method will depend on the individual patient's needs. Han Bor Fam, MD, Singapore, will explain his patient selection criteria for toric IOLs, based on an accurate diagnosis using different methods to measure the corneal radii and with Daniel Black, MD step-by-step guidelines for patient preparation, including tips on biometry, the use of a toric calculator and other diagnostic tests to improve the outcome of surgery. Dr. Fam will also share his clinical results on the effect of ocular cyclorotation on postoperative toric IOL alignment—and thus astigmatism correcting Con Moshegov, MD power—emphasizing the importance of proper marking prior to toric IOL implantation. Proper preoperative diagnosis is of course only one of several factors that influence a patient's visual outcome following cataract surgery. Many of these factors are directly attributable to the IOL itself—lens design and material attributes such as spherical and chromatic aberration correction, light transmission and clarity of the lens material. Daniel Black, MD, Australia, will discuss the importance of these factors in the particular case of toric IOLs, for which these attributes are even more critical in light of other considerations such as the positional stability of the lens. Dr. Black will show how optimizing the interaction between these factors leads to optical synergy—an outcome that is far superior to the sum of the individual factors. Beyond toric IOLs, astigmatism correction can also be made on the corneal plane using an excimer laser. But the excimer laser is just a tool with which to make the ablation. Because corneal astigmatism correction requires accurate corneal diagnosis followed by a customized ablation for optimum visual performance, the aberrometer is the critical factor—the veritable brain of the operation. Con Moshegov, MD, Australia, will discuss his clinical results using a new high definition aberrometer: the iDesign (Abbott Medical Optics, AMO, Santa Ana, Calif.), which has a resolution that is five times higher than that of Wavescan, its predecessor. According to AMO, the iDesign has a significantly higher dynamic range than previous generation devices, covering –16 to +12 D of sphere, cylinders up to 8+ D, and higher order aberrations up to 8 µm RMS. The high definition HartmannShack wavefront sensor allows the iDesign to capture more eyes, including those with complex corneas as a result of previous RK, keratoconus, or decentered ablations. AMO states that Iris Registration is engaged during surgery almost 100% of the time, which helps achieve proper astigmatism correction. The 5-in-1 device also includes a gradient topographer, providing even more information for the accurate diagnosis of the eye. Dr. Moshegov will discuss how the use of high definition aberrometry for cylinder correction as well as customized ablation can achieve outcomes "better than 20/20."
