Ringless Premium Intraocular Lenses - a Narrative Review of Technological Advances.
Review in Maedica, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The standard method for achieving presbyopia correction after cataract extraction has traditionally centered on intraocular lens (IOL) optics featuring concentric diffractive patterns or combinations of diffractive and refractive elements, or "rings". While there has been a transition from simple monofocality to intricate polyfocality in IOLs, this has been accompanied by associated side effects. Halos, glare, reduced contrast sensitivity, waxy vision, low reading speed, reduced depth of focus and difficulty in night vision and driving are important photic phenomena that IOL developers have attempted to improve for decades. "Ringless IOLs" refers to lenses that provide an extended range of vision without relying on concentric diffractive rings or annular diffractive structures on the optic. We have also clarified that ringless designs may use different optical strategies, including refractive, asymmetric, transitional, or other non-annular optical profiles. Recently introduced IOLs without concentric diffractive rings include light-adjustable IOLs, polyfocal progressive IOLs, spiral architecture IOLs and non-diffractive segmented multifocal IOLs. These advanced-technology IOLs circumvent the drawbacks of concentric annuli through the use of continuous optical profiles. As far as we know, the present narrative review is the first such review that includes published articles from 2000 to 2026 to describe the current status of these IOLs and the nuances required to achieve best results after IOL implantation.
