Visualising rays in IOLs
The study visualized and analyzed the optical performance of four intraocular lens (IOL) models using a ray propagation imaging technique and modulation transfer function (MTF) measurements. The IOLs included a monofocal, bifocal, trifocal, and extended-depth-of-focus (EDOF) lens. The results sho...

EDOF IOL research
This study compares the image quality of three extended depth-of-focus (EDOF) intraocular lens models in monochromatic and polychromatic light. The results show that EDOF IOLs are more resistant to chromatic effects and provide better through-focus performance than monofocal IOLs, but differences...

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.
