Another publication from the David J Apple Center for Vision Research: in the latest Journal of Refractive Surgery, the Heidelberg group evaluated the visual outcomes when thirteen cataract patients received a small-aperture IC-8 IOL (AcuFocus, Irvine, CA) in one eye and a segmental-refractive Lentis Mplus LS-313 MF20 IOL (Oculentis, Berlin, Germany) in the fellow eye.
Functional Outcomes and Reading Performance After Combined Implantation of a Small-Aperture Lens and a Segmental Refractive Bifocal Lens Hyeck-Soo Son, MD; Ramin Khoramnia, MD; Timur M.

Five months after the operation, the mean binocular visual results demonstrated UDVA, UIVA, and UNVA values of -0.04 ± 0.11, 0.00 ± 0.10, and 0.11 ± 0.08 logMAR, respectively. The binocular distance-corrected reading performance test also confirmed the improved visual function, with an intermediate reading acuity of 0.12 logMAR at 69.21 cm and a near reading acuity of 0.19 logMAR at 41.63 cm.
The mean halo size was 32.54 ± 22.38, mean halo intensity was 34.46 ± 21.95, mean glare size was 9.00 ± 17.47, and mean glare intensity was 9.92 ± 16.84.
Prof. Auffarth commented this is a new concept of combined implantation of a small-aperture IOL and a segmental-refractive bifocal lens and in our study we showed good results in far and intermediate distances and functional results at near distance. The combination of IOLs also causes minimal photic phenomena.
