O ptimizing machine settings is an important factor in successful cataract surgery, but it is often overlooked or under- emphasized in phaco education. The 2013 ASCRS Clinical Survey confirmed strong educational interest in this topic for a majority of cataract surgeons, regardless of their experience. Like the simplicity of a point- and-shoot camera, using the same phaco machine settings throughout every case might at first seem ap- pealing. However, because the ultra- sound power and fluidic objectives change between the different stages of nuclear emulsification, modifying these settings can improve both sur- gical efficiency and safety. Thanks to multiple, preprogrammed memory settings, surgeons can now use the foot pedal to seamlessly alter these parameters intraoperatively. Much as cameras allow you to choose precon- figured settings for sports, portrait, or nighttime photography, we can preconfigure a package of settings for sculpting, chopping, fragment removal, or epinucleus aspiration. Finally, understanding certain principles and objectives allows us to further alter and optimize our phaco machine parameters for more complicated cases, such as those with weak zonules, brunes- by David F. Chang, MD Reviewing phaco fundamentals: How to optimize settings for routine and complex cases Accreditation Statement This activity has been planned and implemented in accordance with the Essential Areas and policies of the Accreditation Council for Continuing Medical Education through the joint providership of the American Society of Cataract & Refractive Surgery (ASCRS) and EyeWorld. ASCRS is accredited by the ACCME to provide continuing medical education for physicians. Educational Objectives Ophthalmologists who participate in this course will: • Describe platform-specific phaco settings to establish a baseline to customize settings in practice; • Discuss and integrate best practices and phaco techniques for routine cataract surgery, including nuclear disassembly, hydrodissection, efficient use of fluidics and phaco power; and • Establish best practices for successfully navigating common phaco complications and surgical challenges. Designation Statement The American Society of Cataract & Refractive Surgery designates this live educational activ- ity for a maximum of 0.5 AMA PRA Category 1 Credits.™ Physicians should claim only credit commensurate with the extent of their participation in the activity. Claiming Credit To claim credit online, participants must visit bit.ly/1zv6sQv to review content, complete the post-activity test, and credit claim. All participants must pass the post-activity test with a score of 75% or higher to earn credit. Alternatively, the post-test form included in this supplement may be faxed to the number indicated for credit to be awarded, and a certificate will be emailed within 2 weeks. When viewing online or downloading the material, standard internet access is required. Adobe Acrobat Reader is needed to view the downloaded materials. CME credit is valid through January 31, 2015. CME credit will not be awarded after that date.
