75 EW REFRACTIVE March 2017 patients complain of loss of quality of vision, the first thing you want to check is whether they have residual has a toric option available, which broadens its appeal, and a very high level of patient satisfaction and acceptance," Dr. Foster said. For patients who desire near reading performance and have a less strong desire for intermediate perfor- mance, higher add multifocal lenses like the ReSTOR 3.0 or the Tecnis 4.0 are the two main choices. "For most patients with a near reading requirement, I prefer the ReSTOR 3.0 because I believe there are fewer is- sues with nighttime glare and halos, and it has a little bit better interme- diate performance. I tend to use the Tecnis 4.0 for patients with short arms that therefore need strong reading performance and closer than normal reading distances," Dr. Foster added. Patient selection Dr. Donnenfeld said that the IOL chosen for each patient is predicated on the patient's visual needs and his or her demand for quality vision at distance. "When patients are asking for a presbyopic lens solution, they expect to be able to read, but they also demand vision at distance. The new low add lenses have dramati- cally improved vision at distance, which has made them more popular and has gained patient satisfaction," he explained. The Symfony IOL is an extend- ed range of focus lens, and it doesn't have two different focal points. Instead, it has an extended focal point that goes from near out to dis- tance. "There is no point in between where the patient loses vision, so the patient has depth of focus where he or she can see things at different distances. Traditional multifocal IOLs have two distinct focal points, and between those two focal points, there is usually a loss of vision. The Symfony lens is calibrated to provide an extended depth of focus. In my opinion, it gives the highest quality of distance vision of any lenses we have seen in the multifocal category. For this reason, the lens has become extremely popular in a very short period of time in the United States. However, even with the Symfony lens, there is some loss of quality of distance vision," Dr. Donnenfeld added. "I have seen a tremendous increase in demand. I think patients are looking for these solutions, over- whelmingly. We are doing a much better job of providing them with the outcomes they are looking for. When you are evaluating someone for a multifocal lens preoperative- ly, you want to make certain that he or she is an optimal candidate, which means good retinal func- tion, good corneas, and no macular degeneration.
