The key principle defining an extended depth of focus IOL is a single, contiguous, elongated focal point that enhances depth of focus. An ideal EDOF IOL would provide a sharp focus over a …

Oct 2, 2023 · Two EDOF IOL designs were created and optimized for the Liou-Brennan schematic model eye using Zemax ray tracing software. Each lens was optimized to achieve a maximum …

Extended 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 …

Nov 12, 2023 · The Vivity IOL generates the extended depth of field by means of the aspherical front lens surface and a spherical rear surface. To simplify this, the Vivity has a raised step like …

Designing EDOF lenses requires several (usually conflicting) goals. First, maximizing the length of the channel to give high performance for a broad range of object distances.

Jan 6, 2022 · This study aimed to compare clinical outcomes obtained after implanting two different optical designs of EDOF IOLs: the Mini Well Ready (SIFI Medtech, Catania, Italy) and …

Design of the intraocular lens (IOL) Evolve: a circular refractive extended depth-of-focus (EDOF) zone, 1.7mm large, for near vision (+2.50D addition), is surrounded by a far vision zone. The …

Two EDOF IOL designs were created and optimized for the Liou-Brennan schematic model eye using Zemax ray tracing software. Each lens was optimized to achieve a maximum Strehl ratio …

Nov 1, 2018 · It is a biconvex, anterior aspheric and posterior achromatic diffractive surface IOL with an echelette design and the ability to reduce chromatic aberration. Bilateral implantation …

Jun 9, 2023 · EDOF lenses are those that can stretch the focal point of the retina, creating an area in which the image is good enough to offer an adequate solution to the patient in terms of …
