To achieve a sustained good functional outcome after implantation of an intraocular lens (IOL), two factors in particular are of major importance, namely the optics and the material of the IOL. With recent advances in technology and the introduction of new IOL optics, surgeons today have the opportunity to choose from various optical designs that not only influence spectacle independence, but also have an impact on the postoperative quality of vision.

Advancements in surgical techniques have changed the spectrum of complications and reasons for explantation when using IOLs. Reports of material opacification have increased in the literature. In hydrophilic IOLs, calcifications have been reported. For hydrophobic IOLs, the development of "glistenings" is described. The different material opacities influence the optical quality to varying degrees. Furthermore, IOL materials can interact with other substances/liquids in the eye.

In this Special Issue, we are looking for research including new findings in the field of optical and material properties of IOLs. Laboratory studies, clinical studies, and review articles are of interest.

Potential topics include but are not limited to the following:

• Extended Depth of Focus (EDOF) IOLs
• Multifocal IOLs
• “Modern” monofocal IOLs
• Surface coating
• IOL opacification
• IOL calcification
• Glistenings
• Optical bench measurements
• Subsurface nanoglistenings
• IOL material interaction
• Straylight
