Sponsored by Abbott Medical Optics Evolving technology and outcomes in cataract and refractive surgery The news magazine of the Asia-Pacific Association of Cataract & Refractive Surgeons APACRS Supplement to EyeWorld Asia-Pacific Winter 2017 Suhas Haldipurkar, MD Benefits of extended range of vision optics for presbyopia correction universal eligibility criteria, and is the ideal implant for a wider range of presbyopic cataract surgery patients. Way to success To successfully incorporate the extended range of vision IOL into their practice, sur- geons must first believe in the product, putting their faith in the results of the first few cases. Once they have accepted the IOL, they need to change their counseling style. They need to widen the scope for this prod- uct, positioning it as a product for one and all—take the exclu- sivity out of the product. As with multifocal IOLs, good surgery with a well-cen- tered IOL remains mandatory, a huge difference, putting the lens in a different class. Why extended range of vision IOL The Symfony extended range of vision IOL uses the time-test- ed Tecnis lens platform that provides visual satisfaction, not just "numbers." The platform is an excellent product for mono- vision and mix-and-match IOLs if needed. It is an ideal IOL exchange option for patients unhappy with their multifocal implants. The extended range of vision IOL provides seamless range of vision from near to far and scores better on contrast and photic phenomenon than multifocal IOLs. In further con- trast to multifocals, this IOL has image quality. In terms of glare and halos, the achromat tech- nology makes the extended range of vision IOL comparable to monofocal IOLs. Compared to standard multifocal IOLs, the extended range of vision IOL increases depth of focus to provide better intermediate and near vision without affecting distance vision. Negative aberrations combined with tightly controlled chromatic aberrations also help in achieving extended range of vision. Meanwhile, glare and halos are decreased. Admittedly, visual per- formance at near is modest compared to multifocals and reading add may be needed for fine print, but the absence of multiple images simultane- ously cast on the retina makes P resbyopia-correct- ing IOLs have been around for almost two decades, but use still hovers around 4.5% globally. This is due to a combination of issues with quality, overcau- tious doctors, a too-high qual- ifying bar for finding the "Mr. Right" patient, and too many expectations from patients. Entering this landscape, could extended range of vision optics be the magic pill sur- geons have been waiting for? The Tecnis Symfony IOL (Abbott Medical Optics, Abbott Park, Illinois) combines two complementary enabling technologies: the proprietary diffractive echelette design that introduces a novel pattern of light diffraction that elon- gates the focus resulting in an extended range of vision of about 1.5 D—sufficient to provide good vision—and ach- romat technology that reduces chromatic aberration to boost Suhas Haldipurkar, MD, Laxmi Eye Institute, Mumbai, India Figure 1.

The symposium, sponsored by Abbott Medical Optics (Abbott Park, Illinois), featured some of the world's top experts discussing the latest IOL, phaco, and refractive technologies, including extended range of vision and toric IOLs, hybrid pump systems, and wavefront-guided laser refractive procedures.
