Prevalence of corneal astigmatism in patients undergoing cataract surgery in India.
Article in Bioinformation, 2025. 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
Corneal astigmatism is common among patients presenting for cataract surgery. Hence, understanding its pattern is essential for optimal surgical planning and visual outcomes. This study investigated the prevalence, type, and severity of corneal astigmatism in 320 cataract surgery candidates aged 40 years and above at RIO, RIMS, Ranchi, India. Automated keratometry and corneal topography were used to classify astigmatism by orientation and magnitude. Corneal astigmatism was present in 89.4% of patients, with 68.1% showing clinically significant levels (≥1.0 D), most commonly with-the-rule astigmatism, followed by against-the-rule and oblique types. These findings highlight the importance of thorough preoperative astigmatism assessment and appropriate corrective planning to ensure optimal postoperative visual outcomes.
