Validation of Clinical Protocol of Astigmatism Induction in Pseudophakic Patients.

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
Purpose: Validate a novel approach for assessing residual astigmatism's impact on visual acuity in pseudophakic patients using defocus curves and spherical equivalent compensation. Materials and Methods: Thirteen patients over 40 with cataracts and normal ophthalmological examinations were enrolled in a prospective, non-randomized cohort study. The defocus curve method was employed, wherein visual acuity was measured with spherical lenses ranging from -2.50 to +2.50 diopters in 0.5 diopter increments based on subjective refraction. Cylindrical lenses (+1, +2, and +3 diopters) were introduced at each spherical diopter's 90° and 180° axes. Curves' results were compared at each defocus point to assess the impact of astigmatism. The Kruskal-Wallis test was used to determine if astigmatism significantly affected visual acuity post-phacoemulsification surgery with intraocular lens implantation. Results: Significant Conclusion: This novel methodology is both reproducible and valuable. It offers potential insight into residual astigmatism tolerance in pseudophakic patients. Its application may aid in surgical planning and intraocular lens decision-making.
