Ray-Tracing-Guided Femtosecond LASIK: Refractive Outcomes, Visual Quality and Patient Satisfaction.

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: To assess the refractive outcomes, visual quality, and patient satisfaction after ray-tracing-guided femtosecond laser-assisted in situ keratomileusis (FS-LASIK) for the correction of moderate-to-high myopia and myopic astigmatism. Methods: In this consecutive case series retrospective study, 51 patients (101 eyes) with moderate-to-high myopia and myopic astigmatism underwent ray-tracing-guided FS-LASIK. Visual acuity, manifest refraction, objective and subjective visual quality, patient satisfaction were assessed over 3 months. For objective visual quality, InnovEyes Sightmap was used to measure the higher-order aberrations (HOAs) over 5-mm optical zone, and Optical Quality Analysis System II was used to evaluate the modulation transfer function cut off (MTF Results: Regarding visual and refractive outcomes, at 3 months, uncorrected distance visual acuity reached ≥ 20/20 in all eyes, ≥20/16 in 69% of eyes, and ≥20/12.5 in 18% of eyes. Best-corrected distance visual acuity was better in 61% of eyes. All eyes achieved manifest refractive spherical equivalent within ± 1.00 D and 86% of eyes achieved cylinder within ± 0.25 D. As for objective visual quality, total HOA increased significantly ( Conclusion: Ray-tracing-guided FS-LASIK may be an effective, safe and predictable procedure for moderate-to-high myopia and myopic astigmatism. It yielded favorable refractive outcomes, maintained objective visual quality, and achieved high patient satisfaction.
