Three-Month Visual and Refractive Outcomes of Keratorefractive Lenticule Extraction (KLEx) for Myopia and Myopic Astigmatism Using the VISUMAX 800 in 1611 Eyes.

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
introductionThis retrospective, single-center study of consecutive eyes evaluated early visual and refractive outcomes following keratorefractive lenticule extraction (KLEx) using VISUMAX 800 femtosecond laser (Carl Zeiss Meditec) for myopia and myopic astigmatism in a large population.
methodsAdult patients with a myopia up to - 10.00 D and astigmatism up to 5.00 D were treated in this study. Uncorrected distance visual acuity, manifest refraction, corrected distance visual acuity (CDVA), and high-order aberrations (HOA) were assessed at the 3-month postoperative visit.
resultsIn total, 1611 eyes were included in this study. Mean preoperative manifest spherical equivalent (SEQ) was - 4.49 ± 1.87 D. At the 3-month postoperative visit, UDVA was 20/20 or better in 99% of eyes, compared to 100% preoperatively. The achieved SEQ was within ± 0.50 D of the intended correction in 98.7% of eyes, and within ± 1.00 D in 99.8%. Residual refractive astigmatism was ≤ 0.50 D in 97.3% of eyes. Mean postoperative total HOAs was 0.13 ± 0.12 µm. No eyes lost two or more lines of CDVA.
conclusionEarly outcomes following KLEx using the VISUMAX 800 demonstrated excellent accuracy and predictability in the treatment of myopia and myopic astigmatism.
