WebNov 17, 2024 · Extended BPF (eBPF) is a kernel technology that is available in Linux 4.x+. You can think of it as a lightweight sandboxed VM that runs inside of the Linux kernel and can provide verified access to kernel memory. As shown in the overview below, eBPF allows the kernel to run BPF bytecode.

WebExtended depth-of-focus (EDOF) is a new intraocular lens (IOL) technology in the treatment of presbyopia. In contrast to multifocal (MF) IOLs, EDOF lenses create a single elongated focal point, rather than several foci, to enhance depth of focus. In this way, EDOF IOLs aim to reduce photic phenomena, glare, and halos, which have been reported ... WebExtended Depth of Focus (EDOF or EDF), or Extended Range of Vision, is a new technology that has recently emerged in the treatment of Presbyopia-correcting IOLs. In contrast to multifocal intraocular lenses (IOLs) used in treatment of presbyopia , EDOF lenses work by creating a single elongated focal point to enhance “range of vision” or ...

WebThe EDOF IOL, or extended range of vision IOL, is a new technology in the treatment of presbyopia-correcting lenses. The basic optical principle is to create a single-elongated focal point to enhance the depth-of-focus, on the contrary to monofocal IOLs (in which light is focused on one single point) or MF IOLs (having 2 or 3 discrete points).
