2019年2月1日 · MF-IOLs can play an important role in decreasing spectacle dependence, although traditional contraindications remain a limiting factor. Blending of near and intermediate add powers with MF-IOLs should be considered in …

1. Mini Well Ready型IOL：是意大利SIFI 公司生产基于球差设计的一片式双非球面 EDOF型IOL，其总直径为10.75mm，光学面直径为6mm，并具有滤过紫外线的功能。该IOL光学面包含具有正球差的中央光学区、具有负球差的中周光学区及周边部的单焦点区域等三个环形区域。

Multifocal and accommodating intraocular lenses are artificial intraocular lenses (IOLs) that are designed to provide focus of both distance and near objects, in contrast to monofocal intraocular lenses which only have one focal point and correct distance vision.

2019年2月26日 · Learn how multifocal intraocular lenses (IOLs) like AcrySof IQ ReSTOR and Tecnis Multifocal IOL can reduce your need for glasses after cataract surgery.

2024年11月8日 · A multifocal lens is an artificial intraocular lens (IOL) designed to provide focus for both near and distance vision. Unlike standard monofocal lenses, which only correct for a single type of vision, multifocal lenses have multiple focal points, allowing patients to see clearly at multiple distances without glasses or contact lenses.

The multifocal intraocular lenses (IOLs) available are often able to restore visual function and allow spectacle independence after their implantation with great levels of patient satisfaction.

2023年8月7日 · Many companies are looking far past the current options of diffractive or refractive multifocal IOLs, toward what is often referred to as the “Holy Grail” of IOLs: a truly accommodating IOL. Such an IOL could change its refractive power, driven by contraction of the ciliary body—just as in a prepresbyopic human eye.

2022年9月28日 · Multifocal IOLs (MFIOLs) are IOLs that have been designed so that some of the light is split off to focus on near objects. Designs have often included concentric rings in the center of the IOL to have alternating focus between distance and near. MFIOLs have improved substantially over the past ten years.

Presbyopia-correcting intraocular lenses (IOLs) including MFIOLs provide spectacle independence for both near and distance vision. Three general optic principles have been applied to provide multifocality in the present day IOLs: multizonal refractive, diffractive, and extended range of vision (EROV) designs.

intraocular lenses (MF-IOLs). Since its creation in the 1980s, MFIOLs has undergone various technical improvements, including trifocal implants and implants with extended depth of vision. Excellent results were achieved thorough pre-operative check, including the visual needs of the patients and the inherent eye anatomy. This analysis offers a ...
