Comparative Outcomes of Robotic Laser Arcuate Keratotomy and Toric Intraocular Lenses for the Management of Lower Magnitude Astigmatism at the Time of Cataract Surgery.
Article in Clinical ophthalmology (Auckland, N.Z.), 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
Purpose: To compare refractive and visual outcomes between robotic laser-assisted arcuate keratotomy (AK) guided by the Wörtz-Gupta Formula Patients and Methods: This retrospective, single-surgeon case series included 105 eyes with robotic laser-assisted AK using the ALLY platform with iris registration (LENSAR, Inc, Orlando, FL), and 53 received a toric IOL, using ALLY's IntelliAxis refractive capsulorhexis for intraoperative toric IOL alignment. The primary outcome measure was postoperative residual refractive cylinder at postoperative week 4. Secondary outcomes included uncorrected distance visual acuity (UDVA), best-corrected distance visual acuity (CDVA), and spherical equivalent (SE) refraction. Subgroup analyses evaluated outcomes by astigmatism orientation (with-the-rule [WTR] versus against-the-rule [ATR]). Results: Postoperative residual refractive cylinder did not differ significantly between groups (-0.14 ± 0.16 D AK vs -0.21 ± 0.28 D toric, Conclusion: In eyes with low-magnitude regular corneal astigmatism undergoing cataract surgery, robotic laser-assisted AK guided by the Wörtz-Gupta Formula
