Visual outcomes after femtosecond-assisted intracorneal MyoRing implantation: 18 months of follow-up.
Article in Graefe's archive for clinical and experimental ophthalmology = Albrecht von Graefes Archiv fur klinische und experimentelle Ophthalmologie, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 1 of them a synthesis that pooled it.
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 determine the long-term results of femtosecond-assisted MyoRing implantation for the treatment of keratoconus.
methodsIn this prospective, non-randomized, interventional clinical study, 47 eyes of 46 patients with keratoconus grade 1 to 3 entered the study. For all patients, a MyoRing (Dioptex, GmbH, Austria) was implanted using a femtosecond laser (Femto LDV, Ziemer, Germany).
resultsAt 18 months, mean uncorrected and best corrected visual acuity was 0.41 ± 0.19 logMAR, (P = 0.004) and 0.62 ± 0.22 logMAR (P < 0.001), and mean manifest refraction spherical equivalent was -0.38 ± 2.62D (P < 0.001). The central 3-mm maximum and mean keratometry decreased by 5.20 ± 3.06D and 4.77 ± 2.47D, respectively (both P < 0.001), and the 8-mm maximum keratometry decreased by 1.16 ± 5.50D (P = 0.185). Central and minimal corneal thickness showed an insignificant increase. Both corneal hysteresis and corneal resistance factor showed an insignificant decrease of about 0.13 mmHg. Endothelial cell count decreased by 215.43 ± 300.55 cell/mm(2) (P < 0.001). Twenty-six subjects (55.3 %) had halo vision at night and 24 subjects (51.1 %) had glare at night.
conclusionsFemtosecond-assisted intracorneal MyoRing implantation can be an appropriate treatment option in keratoconus patients with central corneal protrusion, but the incidence of optical disturbances can be relatively high.
