Comparative effectiveness of VISUMAX 800 with keratorefractive lenticule extraction and FS-LASIK in the treatment of myopic astigmatism.
Article in Journal of cataract and refractive surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 compare the visual and refractive outcomes of keratorefractive lenticule extraction (KLEx) using the VISUMAX 800 femtosecond laser and femtosecond laser-assisted in situ keratomileusis (FS-LASIK) performed using the VISUMAX 800 femtosecond laser and the EX500 excimer laser in the treatment of myopic astigmatism.
settingSingle-center, private ophthalmology center.
designRetrospective comparative study.
methods237 eyes (133 KLEx, 104 FS-LASIK) were evaluated. Cyclotorsion alignment in KLEx was achieved using the Callisto Eye system integrated with VISUMAX 800. Refractive outcomes, vector analysis (Alpins method), and safety and efficacy indices were compared between groups at 1 month and 6 months postoperatively.
resultsAt 6 months, both groups achieved comparable uncorrected distance visual acuity (0.01 ± 0.04 logMAR) and corrected distance visual acuity. Mean spherical equivalent was closer to emmetropia in the KLEx group (-0.04 ± 0.18 diopters [D] vs -0.10 ± 0.15 D, P = .007). Residual cylinder was lower in KLEx (-0.14 ± 0.19 D vs -0.20 ± 0.20 D, P = .010). Vector analysis showed lower difference vector in KLEx (0.14 ± 0.19 D vs 0.21 ± 0.21 D, P = .009), while FS-LASIK had a slightly higher correction index (correction index: 1.02 vs 0.97, P = .005).
conclusionsBoth KLEx and FS-LASIK performed using the VISUMAX 800 achieved excellent refractive outcomes, with KLEx procedures incorporating an image-guided static cyclotorsion alignment strategy and demonstrating excellent refractive and vector analysis results.
