EW NEWS & OPINION September 2016 31 IOLs. This also makes it a surgeon- friendly lens because it gives us the opportunity to provide our patients with excellent quality of vision with a lower risk of dissatisfaction. EW this lens is the near point. It is very good for mid-range activities, but for fine reading, I counsel patients that they may need to wear glasses. In my opinion, the Symfony lens provides what patients have wanted: They don't have to give up good distance vision or driving at night for excellent range of vision at near and intermediate; they can see the menu in a restaurant, the dashboard in their car, and com- fortably use their computers and smartphones. I had an interesting thing happen among my study patients. A group of them was in the waiting room together for their first day postop exams. It quickly became clear which patients had gotten the Symfony lens because they were so thrilled with their near vision. After the study, one of the monofocal patients had his lenses explanted due to dissatisfaction with reading. I implanted bilateral multifocal lenses instead. I have participated in a number of FDA trials and this is the first instance I can recall where I have needed to explant a control lens. Peace of mind for surgeons Another aspect of the Symfony lens I like is that it is very forgiving of residual refractive error. It delivers 20/20 vision even in the presence of up to a diopter and a half of astigmatism. Because it extends the range of useful vision, patients will still have good outcomes even if the refraction is off by +0.25 or +0.50 D. They may not get as much near vision as intended, but they won't lose distance acuity as they would with the same amount of error in the presence of a multifocal IOL. For surgeons who have been waiting for a presbyopia-correcting lens that minimizes visual distur- bances yet offers a full range of near vision in refractive cataract surgery, Symfony is a good opportunity. I feel confident recommending it for a wider range of patients than before—patients who are more demanding, who drive a lot at night, or who are post-LASIK, for example. I am also excited about the toric version. I have found that Symfony is more patient-friendly than previous generations of presbyopia-correcting Editors' note: Dr. Donnenfeld has financial interests with Abbott Medi- cal Optics, Alcon (Fort Worth, Texas), and Bausch + Lomb (Bridgewater, New Jersey).
