56 EW MEETING REPORTER July 2012 Highlights continued from page 55 Reporting live from the 2012 APACRS annual meeting, Shanghai, China Ang Chong Lye, M.D., Singapore Sophisticated surgery: Before, during, after The Combined Symposium of Cataract & Refractive Societies (CSCRS) gathered together a "very sophisticated group of surgeons" from all over the world to explore this meeting's theme of the "Sophisticated Surgeon." Specifically, the symposium was designed to break down and exam- ine each stage of what the sympo- sium's chair and APACRS president Graham Barrett, M.D., called "the very best way to do what [cataract and refractive surgeons] do," i.e., looking at the strategies of the sophisticated surgeon before, during, and after surgery. In describing his personal choice of surgical technique, for example, Dr. Barrett considered the safety, efficacy, and efficiency of three approaches to surgery: divide and conquer; horizontal chop techniques typified by stop and chop; and vertical chop techniques, particularly the phaco-axe. Dr. Barrett's choice is the Editors' note: This Meeting Reporter contains original reporting by the EyeWorld news team from the 2012 APACRS annual meeting, Shanghai.

Beatrice Cochener, M.D., France Despite advances in modern cataract surgical technology and techniques, complications can still occur. The final aspect of "sophisti- cated surgery" examined by the CSCRS involved the management of these complications. For example, a useful alternative strategy for correcting residual refractive errors, said Beatrice Cochener, M.D., Brest, France, is piggyback IOL implantation, which minimizes surgical trauma, corrects the error predictably, is reversible, and has produced encouraging results thus far. Laser vision correction is another alternative, said Steve Schallhorn, M.D., San Diego. Its advantages include the precision of excimer lasers and a wide range of treatment. It is indicated in patients with no corneal pathology and suffi- cient corneal tissue, and while visual recovery may be fast, it may also be affected by associated conditions such as dry eye. Femto-phaco forum examines budding technology The first-ever femto-phaco forum at the APACRS meeting provided atten- dees with a hard look at the pros and cons of the technology, Wang Zheng, M.D., China specifically focusing on the LenSx (Alcon, Fort Worth, Texas) and Victus (Bausch + Lomb/Technolas, Rochester, N.Y./Munich, Germany) platforms. Dan Tran, M.D., Newport Beach, Calif., went over the techni- cal aspects of the LenSx. One aspect of the laser Dr. Tran finds especially beneficial is the depth of the OCT scan. "Most commercial OCT [units] can only scan 2-3 mm in depth. This laser can scan down to 8 mm in depth," he said. Michael Knorz, M.D., Mannheim, Germany, personally finds great value in the astigmatism- correcting aspect of the LenSx. "Astigmatism correction hasn't been stressed here sufficiently," he said. "I do a lot of multifocal IOLs, so I do need patients to see 20/20 without correction. Now I can reliably correct astigmatism at the time of surgery." Frieder Loesel, Ph.D., Germany, gave an overview of the Victus system. "The technology of the Victus has four core components," he said. "A curved patient interface together with intelligent pressure sensors minimizes corneal folds." Furthermore, the laser has both cataract and refractive applications making a "versatile platform," he
