175 March 2015 EW MEETING REPORTER These IOLs offer high spectacle inde- pendence, but patients may com- plain of halos. Dr. Donnenfeld tells all multifocal IOL patients that there is a 1 in 40 chance that he will need to exchange their IOL. The reason that patients may not tolerate these lenses is because of simultaneous vision. With a multifocal lens, the patient sees 2 images, but the brain suppresses one of them. Halos can be caused by the out-of-focus image. What is needed in a multifocal is MD, New York, discussed options for multifocal/advanced technology IOLs, including the AcrySof Toric ReSTOR multifocal IOL (Alcon), Tecnis low add multifocal IOL (Abbott Medical Optics), and the Tecnis Symfony IOL (Abbott Medical Optics). About 50% to 70% of patients who come into the practice have astigmatism, Dr. Solomon said. One of the biggest challenges with mul- tifocal lenses is managing astigma- tism. "Multifocal lenses are very par- ticular," he said. "You have to nail that correction." Dr. Yeu discussed Tecnis low add multifocals, particularly addressing some of the different Tecnis options. There is high patient satisfaction with the Tecnis +3.25 D multifocal, she said. About 94% of patients would elect to have the same IOL again, and 82% achieved 20/25 or better binocular uncorrected near visual acuity at 6 months at best distance. Meanwhile, with the Tecnis +2.75 D multifocal, more than 80% were reporting comfortable vision at all distances, and three-fourths of patients were reporting no difficulty at all with glare and halos at the 6-month postoperative visit. Considerations that need to be taken into account with the low add multifocals include the patient's visual needs, as well as his or her recreational activities and hobbies. The key advantage of having these lower adds is that the glare and rings around lights are significantly improved, but this still does not change the strict criteria that should be followed when looking for a mul- tifocal candidate, Dr. Yeu said. Dr. Donnenfeld highlighted the Tecnis Symfony lens, which recently finished a Food and Drug Adminis- tration trial and is awaiting approval for use in the U.S. The lens is popu- lar in Europe, he said. Multifocal IOLs are Dr. Donnenfeld's best option for spectacle independence following cataract surgery. He said that his multifocal IOL patients are both his happiest and unhappiest patients. quality vision, less halos, and no contrast sensitivity loss, Dr. Donnenfeld said. The Symfony merges 2 compli- mentary enabling technologies, he said. "You lose contrast but not as much as you do with other IOLs," Dr. Donnenfeld said. The diffractive echelette design feature introduces a novel pattern of light diffraction that elongates the focus of the eye. The Symfony IOL delivers a level of UCVA and BCVA at least comparable to a monofocal IOL at distance, Dr. Donnenfeld said. With this lens, dysphotopsias are significantly re- duced compared to multifocal IOLs. Patient satisfaction is high, with excellent intermediate vision and good near vision.
