Reasons for explanting IOLs
The Apple Lab research team analyzed 200 intraocular lens (IOL) explants, finding that the main reasons for explantation were IOL opacification (76.5%) and dislocation (13.5%). Most explants were hydrophilic acrylic lenses from a single manufacturer.

Small-aperture IOL results.
Researchers evaluated the visual outcomes of 13 cataract patients with a small-aperture IOL in one eye and a segmental-refractive bifocal IOL in the other, showing improved binocular visual results and minimal photic phenomena.

Straylight from glistenings
Glistenings in hydrophobic acrylic intraocular lenses (IOLs) are fluid-filled microvacuoles that can negatively impact visual function. Studies have shown that severe glistenings can mildly reduce contrast sensitivity and visual acuity. The formation of glistenings is highly dependent on IOL material, with hydrophobic acrylic materials being most affected. In-vitro studies have been conducted to accelerate glistening formation and evaluate the optical quality of IOLs. Results indicate that a limited number of glistenings does not significantly affect image quality, but dense glistenings can lead to small deteriorations in optical performance.
