EW REFRACTIVE 72 September 2018 Comparison The AT LISA tri diffractive trifocal IOL achieved a UDVA of logMAR –0.03 ± 0.10, an uncorrected in- termediate visual acuity (UIVA) of logMAR 0.08 ± 0.08, and a UNDA of logMAR 0.10 ± 0.10. The MFIOL capacity was 83%, when tested mon- ocularly and with correction, and it was 88% when tested binocularly without correction. Halo and glare strength were 57% ± 11%. The PanOptix diffractive trifocal IOL had a UDVA of logMAR 0.01 ± 0.06, a UIVA of logMAR 0.02 ± 0.02, and a UNVA of logMAR 0.05 ± 0.10. The MFIOL capacity was 80% when tested monocularly and with correc- tion, and 94% when tested binocu- larly without correction. The halo and glare strength were 54 ± 11%. "Both lenses provided a broad range of good binocular vision," Dr. Breyer said. "The AT LISA tri proved slightly better for far vision, while the PanOptix was better at near and intermediate ranges, which was in agreement with tested optical bench measurements. 1 Halo and glare were comparable for both diffractive IOLs but significantly stronger than for phakic eyes (30% ± 16%). It is im- portant to be aware that a postoper- ative period of several months may be needed for satisfying neuroadap- tation, as one study has shown. 2 " According to the outcomes of an unrelated comparative study that investigated the optical performance of three trifocal IOLs, the AcrySof IQ PanOptix, the AT LISA tri, and the FineVision Micro (PhysIOL, Liege, Belgium), the AcrySof IQ PanOptix showed equivalent or better perfor- mance in image quality, resolution, and photic phenomena compared with the other two trifocal IOLs. The study's investigators predicted the PanOptix to provide better interme- diate vision at 60 cm, compared to the 80 cm distance offered by the other two lenses. EW References 1. Carson D, et al.

Contact information Breyer: premiumeyes@augenchirurgie.clinic Halo and glare simulation Glare and halo have proven to be the most common grounds for MFIOL explantation. Knowing an IOL's capacity to induce these bothersome side effects, therefore, has enormous practical value. Using simulation software, Dr. Breyer and his colleagues investigated halo and glare effects in 126 phakic, 52 AT LISA, and 12 PanOptix eyes. The simulation software subjectively matched patient photopsias (binoc- ular, uncorrected eyes) via a graphic user interface. The intensity of visual effects was categorized as none, mild, moderate, or severe. According to the simulation, ap- proximately 25% of phakic eyes had no glare or halo. Mild glare and halo effects were observed in roughly 60% of the phakic eyes, 25% of the PanOptix eyes, and just below 25% of the AT LISA eyes. Moderate glare and halo were observed in roughly 10% of the phakic eyes, and in more than 60% of both the AT LISA and PanOptix eyes. Severe glare and halo were reported in less than 10% of the AT LISA eyes only. Over the past decade, OIS has been bringing together key leaders to collaborate and foster the development of ophthalmic innovation. To celebrate the history of OIS and to commemorate the 10th anniversary of the inaugural summit, the ophthalmology community is invited to come together and help us recognize those who have made a significant impact on innovation. Visit www.ois.net/awards to cast your ballot for the Ophthalmology Innovator Awards. Ballots are due by Wednesday, September 19th, 2018 at 5:00 pm PDT.
