Keratometry repeatability in healthy and post-refractive surgery eyes: a comparison of two swept-source devices.
Article in Graefe's archive for clinical and experimental ophthalmology = Albrecht von Graefes Archiv fur klinische und experimentelle Ophthalmologie, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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 analyze the keratometry repeatability obtained with two swept-source devices in healthy and post-refractive surgery eyes.
methodsOne hundred volunteers aged between 20 and 55 years were recruited for this study including both healthy and post-refractive surgery eyes. Patients included in the post-refractive surgery group underwent Laser-Assisted in Situ Keratomileusis (LASIK) or Photorefractive Keratectomy (PRK). Three consecutive measurements were taken with the IOLMaster 700 and Anterion and the evaluated measurements were simulated keratometry (Sim K), posterior keratometry (PK), and total keratometry (TK). Repeatability was assessed through the intra-subject standard deviation (Sw), repeatability limit (R), and variability coefficient (CoV).
resultsFifty patients were included in the control and post-refractive surgery groups, respectively. Similar repeatability was obtained for healthy and post-refractive surgery eyes using both devices. For IOLMaster 700, R ranged between 0.16 and 0.22 D for Sim K, 0.09–0.11 D for PK, and 0.18–0.24 D for TK. For Anterion, R ranged between 0.19 and 0.20 D for Sim K, 0.02 D for PK, and 0.21-0.22 D for TK. In general, the control group showed slightly higher Sw and R values than the post-refractive surgery group for TK and astigmatism measurements obtained with both devices.
conclusionsIOLMaster 700 and Anterion demonstrated good repeatability for simulated and total keratometry measurements obtained in healthy and post-refractive eyes. Moreover, the keratometry repeatability was comparable between healthy and post-refractive eyes using both SS-OCT devices.
