Extended depth of focus intraocular lenses – the present and future in cataract surgery

Abstract

The purpose of this article is to evaluate the technology behind intraocular lenses with extended depth of focus, explain how they work, assess their benefits for patients, and summarize our own early experience.

Trifocal and extended depth of focus intraocular lenses – comparative analysis

“…The construction and technology of the lenses differ from each other, depending on the individual company (Table II). They can use various of principle: spherical aberrations, chromatic aberrations or the "pinehole effect" [21,22]. Based on the IOL technologies EDoF can be divided into two main categories: pure EDoF and hybrid EDoF.…”

“…In order to reduce dysphotopsia while maintaining good quality of vision, extended depth of focus (EDoF) IOLs were introduced on the market. Their design and technology differs between the models of individual manufactures, they can use different principles: spherical aberrations, chromatic aberrations or "pinehole effect", but the main goal of the entire group is common -to achieve "pseudoaccommodation" [21,22]. They are intended to ensure a very good distance and intermedi-…”
