NOVEMBER 2019 | EYEWORLD | 17 difference in spectacle independence between those with PanOptix and AT LISA IOLs (100% vs. 89.7%). One of the most common drawbacks to presbyopia-correcting IOLs is the potential for dysphotopsias. 1 The study also evaluated postoperative visual disturbances and found that the frequency of experiencing glare or halo is similar in eyes with PanOptix and AT LISA IOLs, but the severity and "bother" of these disturbances was less in the PanOptix group. However, given that more of the patients undergoing clear lens extraction were in the AT LISA group it is possible that patients who received the PanOptix IOL may be relatively less bothered by postoperative glare and halos compared to their preoperative baseline. Study #2 In "Comparative analysis of defocus curves of both groups. Intermediate vision at 80 cm was superior in the AT LISA group, while interme- diate vision at 60 cm was better in the PanOptix group. This outcome matches the designated intermediate target for each IOL; the diffractive PanOptix IOL contains a +2.17 D add opti- mized for 60 cm viewing, and the diffractive AT LISA IOL has a +1.66 D add optimized for 80 cm viewing. This study further evaluated the outcomes of the two IOLs by generating defocus curves, which measure visual acuity with various posi- tive and negative powered lenses in front of the eye to simulate distances from far to near. By this method, the PanOptix IOL was superior to the AT LISA IOL at +1 D as well as –1 D through –2.5 D, while both had excellent dis- tance (0.5 through –0.5 D) visual acuity. In a post-implant survey, the vast majori- ty of patients with either IOL reported never using spectacles for far or near vision. Yet for intermediate vision, there was a significant From left: Jeff Pettey, MD, Rebekah Gensure, MD, PhD, Rachel Patel, MD, Marshall Huang, MD, Kathrine Hu, MD, Bradley Jacobsen, MD, Ariana Levin, MD, Sravanthi Vegunta, MD, Theresa Long, MD, Abigail Jebaraj, MD, Christopher Bair, MD, Michael Burrow, MD, Christina Mamalis, MD, Michael Murri, MD Source: John Moran Eye Center continued on page 18
