Assessing the clinical outcomes of a novel EDOF intraocular lens: a functional classification approach.
Article in BMC ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundFunctional assessment can help identify the true extended depth of focus intraocular lenses (EDOF IOLs) on the market. This study aimed to demonstrate the eligibility of the 877PEY ELON IOL (Medicontur Medical Engineering) as a suitable model for this category and to assess its efficacy in clinical settings.
methodsIn total, 38 patients (76 eyes) were enrolled in the study with bilateral implantation of the investigational IOL. For functional classification, a distance-corrected monocular defocus curve was taken 3 months postoperatively. At the 3- and 12-month follow-ups, manifest refraction, monocular and binocular distance, intermediate and near visual acuities, contrast sensitivity, and patient-reported outcomes were recorded.
resultsThe defocus range (visual acuity [VA] ≤ 0.2 logMAR) on the distance-corrected monocular normalized defocus curve taken at 3 months was 1.7 D, which falls into the Partial Range of Field Extended (later referred to as PRoF-Ex) category, confirming expectations. The binocular depth of focus (VA ≤ 0.1 logMAR) spanned approximately 0.50 D to -1.50 D, and the functional visual acuity (VA ≤ 0.3 logMAR) spanned approximately 1.00 D to -2.50 D. Monocular CSV-1000 outcomes were above the population's normal ranges. 90.9% of the patients were within ± 0.50 D, and 97.7% were within ± 1.00 D SEQ at the 3-month follow-ups. The outcomes of the VFQ-25 questionnaire demonstrated high scores, and the level of spectacle independence, similar to visual acuity, reflected a strong efficacy in distance and intermediate correction with functional near vision. In terms of photopic phenomena, 90% and 87.5% of patients experienced no-to-moderate rates of glare and halos, respectively. The posterior capsular opacification (PCO) rate was 7.89% at the 12-month follow-up. No adverse events were considered serious.
conclusionsThe 877PEY model demonstrated capability as a PRoF-Ex IOL with remarkable performance. It is safe to use and delivers a high degree of patient satisfaction.
