Correlation between postoperative visual recovery and subjective visual satisfaction in cataract patients with different corneal astigmatism degrees: a retrospective cohort study.
Article in International ophthalmology, 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 investigate the correlation between postoperative visual recovery and subjective visual satisfaction in cataract patients with varying degrees of corneal astigmatism, and to identify factors influencing patient-reported outcomes following modern cataract surgery.
methodsThis retrospective cohort study analyzed 682 eyes of cataract patients who underwent phacoemulsification with standard monofocal non-toric intraocular lens (IOL) implantation targeting emmetropia between January 2022 and December 2022. Patients were stratified into four groups based on preoperative corneal astigmatism: Group 1 (< 0.75 D, n = 250), Group 2 (0.75-1.50 D, n = 245), Group 3 (1.51-2.50 D, n = 121), and Group 4 (> 2.50 D, n = 66). Primary outcomes included best-corrected visual acuity (BCVA), uncorrected distance visual acuity (UDVA), and patient satisfaction scores measured using the modified NEI VFQ-25 questionnaire. Secondary outcomes encompassed visual symptoms and spectacle independence for distance vision.
resultsMean postoperative UDVA improved significantly across all groups (p < 0.001), with Group 1 achieving 0.12 ± 0.08 logMAR compared to 0.36 ± 0.14 logMAR in Group 4. Postoperative BCVA was ≥ 20/30 in 97.1% of all eyes, confirming good visual potential across groups. Patient satisfaction composite scores decreased progressively with increasing astigmatism magnitude (Group 1: 88.4 ± 9.2 vs. Group 4: 67.1 ± 15.8; p < 0.001). Spectacle independence for distance vision was achieved in 92.5% of Group 1 patients versus 45.5% in Group 4. Multiple regression analysis revealed that postoperative UDVA (β = - 0.42, p < 0.001), residual astigmatism (β = - 0.38, p < 0.001), and severity of glare symptoms (β = - 0.21, p = 0.003) were significant independent predictors of reduced satisfaction (adjusted R2 = 0.57).
conclusionsHigher degrees of preoperative corneal astigmatism are associated with reduced postoperative visual satisfaction despite good BCVA outcomes. These findings support a low threshold for astigmatism management and highlight the importance of comprehensive patient counseling regarding expected visual outcomes based on preoperative astigmatism magnitude.
