Refractive outcomes after cataract surgery using swept-source OCT biometry and image-guided toric IOL alignment: a prospective comparative study in normal versus long axial length eyes.
Article in Scientific reports, 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
This prospective comparative study evaluated the refractive accuracy of the ARGOS® swept-source OCT biometer combined with the VERION™ Image-Guided System in cataract surgery using the Barrett Universal II formula. Ninety eyes were divided into Normal Axial Length (AL) (22.5–26.0 mm, n = 50) and Long AL (≥ 26.0 mm, n = 40) groups. All underwent phacoemulsification with PanOptix® Toric IOL implantation. The primary outcome was mean refractive prediction error (RPE) at 1 month. The mean RPE was − 0.07 ± 0.18 D in the Normal AL Group and − 0.05 ± 0.23 D in the Long AL Group (P = 0.375). The percentage of eyes achieving an absolute RPE within ± 0.50 D was 98.0% and 95.0%, respectively (P = 0.574). Mean absolute residual refractive astigmatism was 0.56 ± 0.32 D in the Normal AL Group and 0.47 ± 0.25 D in the Long AL Group (P = 0.110). Visual acuity outcomes were comparable between groups. In conclusion, the combination of ARGOS® segmental biometry and VERION™ digital image guidance yielded high-precision refractive outcomes in long AL eyes that were comparable to normal AL eyes.
