June 2015 25 EWAP FEATURE improved intermediate vision. “These potential game- changing IOLs may change the way we approach intermediate vision. An example of this type of lens is the Symfony,” Dr. Dell said. “This IOL physically resembles a multifocal, but it is not a multifocal. Rather, this lens uses 3 principal optical strategies to achieve its near performance: a diffractive optic to expand a single focal zone as opposed to creating multiple foci, spherical aberration control, and chromatic aberration control. The net result is that distance quality seems to equal that of a monofocal, Views from Asia-Paci c Hiroko BISSEN-MIYAJIMA, MD, PhD Professor and Department Chair, Tokyo Dental College Suidobashi Hospital 2-9-18 Misaki-cho, Chiyoda-ku, Tokyo 101-0061, Japan Tel. no. +81-3-5275-1912 Fax no. +81-3-5275-1912 bissen@tdc.ac.jp P resbyopia correction remains an ongoing topic for discussion since we do not have the best solution. We often discuss the choice between monovision and presbyopia-correcting IOLs. The article describes very interesting survey results regarding the selection of presbyopia correction. My impression of ophthalmologists in the U.S is that they are concerned about the drawbacks of presbyopia-correcting IOLs, especially diffractive multifocal IOLs, such as glare and halo, and decreased contrast sensitivity. However, they seem to prefer presbyopia-correcting IOLs over monovision. When I spoke at the Journal of Cataract and Refractive Surgery Symposium titled “If I were having cataract and IOL surgery today, my choice of IOL would be…” at ESCRS in 2013, I was in the minority among the speakers who chose multifocal IOL. The quality of vision such as contrast sensitivity was the priority in selecting an IOL for their own eyes and most speakers chose monovision. Based on this experience, the preference for multifocal IOL was higher and the reason may be of interest in selecting the new generation multifocal IOLs with lower near addition which improve the intermediate vision. The survey of satisfaction rates for vision at distance, intermediate, and near showed a lower rate for intermediate. Thus, as Drs. Dell and Serafano pointed out, the new generation multifocal IOLs with lower addition and IOLs with extended range of vision would match the needs of patients. However, in my practice in Japan, still over 50% of patients wish for good distance and near vision, and prefer +4.0 D additional power, though they can choose power from +2.5 to +4.0 D. There is a wide variety of choice for presbyopia-correcting IOLs depending on the patient’s lifestyle, just as for monovision.
