Small-aperture IOL results.

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 IOL in the other. Five months after the operation, the mean binocular visual results demonstrated UDVA, UIVA, and UNVA values of -0.04 ± 0.11, 0.00 ± 0

EDOF wavelength dependence

The latest paper from the David J Apple Lab has been accepted for future publication in the influential American Journal of Ophthalmology. In vitro analysis confirmed Symfony’s wavelength dependence: performance was improved at a far distance but was worse at intermediate and near distances. Although the red filter did not improve distance vision, it caused visual deterioration at the near distance.

Optical Quality July 1, 2018

Pars Plana Vitrectomy (PPV) – with instillation of gas into a pseudophakic eye with an acrylic hydrophilic lens – seems to increase the risk for secondary calcification irrespective of the IOL manufacturer. In these cases, IOL exchange is the only treatment option available.
