Elliptical versus circular flap configuration in myopic eyes undergoing femtosecond laser
Article in Indian journal of ophthalmology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 study whether a customized elliptical flap configuration offers any visual, refractive, or biomechanical advantage over the "conventional" circular flaps in patients undergoing myopic laser in situ keratomileusis (LASIK).
methodsA prospective interventional contralateral eye study was undertaken enrolling 290 eyes of 145 myopic patients (≤-6.0D) undergoing LASIK, wherein the corneal flap was created in one eye using a customized elliptical flap configuration versus a conventional circular flap configuration in the other eye. Postoperatively, we compared the visual outcome, change in higher-order aberrations, corneal asphericity, and corneal biomechanics.
resultsThe visual outcomes, including higher-order aberrations, were comparable between the two groups. Changes in spherical aberration (mean: 0.234-0.331 versus 0.234-0.42; P = 0.644), corneal asphericity (-0.32-0.34 versus - 0.34-0.45; P = 0.42), corneal hysteresis (9.35-7.33 versus 9.4-6.71, P = 0.489), corneal resistance factor (9.71-7.40 versus 10.38-6.9, P = 0.181) were comparable between the elliptical and circular groups, respectively.
conclusionWe evaluated the usefulness of a customized elliptical flap configuration for performing LASIK surgery. Our data suggests that elliptical flaps may be associated with superior visual and biomechanical performance compared to circular flaps. This is certainly relevant in eyes with "borderline" pre-LASIK profile to improve patient satisfaction and safety after surgery.
