Real-world outcomes of low-cylinder-power toric intraocular lenses in eyes with mild corneal astigmatism.
Observational study in Journal of cataract and refractive surgery, 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
purposeTo evaluate the effectiveness of astigmatism correction using low-cylinder-power monofocal toric intraocular lenses (IOLs) in eyes with mild corneal astigmatism.
settingTertiary care center in Osaka, Japan.
designSingle-center ambispective observational cohort study.
methodsEyes were categorized into the T2 group (toric IOL with 1.0 diopter [D] cylinder power at the IOL plane), nontoric IOL (T0) group, or Tx group (T3 or higher toric IOLs; ≥1.5 D cylinder power). Eyes with irregular corneal astigmatism or prior ocular surgery were excluded. 3-month outcomes included uncorrected distance visual acuity (UDVA), refractive and subjective astigmatism, and vector analysis.
results75 eyes (25 per group, 46 patients) were analyzed. At 3 months, the T2 group showed significantly lower mean refractive astigmatism (0.45 ± 0.25 D) and subjective astigmatism (0.28 ± 0.34 D) than the T0 group (0.92 ± 0.31 D and 0.69 ± 0.33 D; both P = .000), with better UDVA (logMAR -0.05 ± 0.12 vs 0.08 ± 0.15; P = .002). In paired-eye analyses, T0 eyes had greater refractive astigmatism (0.92 ± 0.32 D) and subjective astigmatism (0.69 ± 0.33 D) than their Tx fellow eyes (0.53 ± 0.33 D; P < .001 and 0.39 ± 0.32 D; P = .002). T2 achieved astigmatism correction comparable with that of Tx in mild-astigmatism eyes. Tx eyes trended toward better UDVA than their T0 fellows ( P = .060).
conclusionsLow-cylinder-power toric IOLs effectively corrected astigmatism and improved visual outcomes in eyes with mild corneal astigmatism, a population previously excluded from toric IOL implantation.
