The Intraoperative Corneal Pachymetry Changes during Accelerated Corneal Cross-linking in Progressive Keratoconus Patients with Thin Corneas.

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 report the intraoperative corneal pachymetry changes during accelerated corneal cross-linking (A-CXL) in progressive keratoconus patients with thin corneas.
methodsThirty-six eyes (mean age, 22.26 ± 4.02 years) with progressive keratoconic thin corneas (<400 μm without epithelium) who underwent A-CXL with ultraviolet (UV)-A (UVA) (9 mW/cm2) using isotonic riboflavin5-phosphate 0.1% with 1.1% hydroxypropyl methycellulose (RF-HPMC, MedioCROSS M) were included in this retrospective study. Intraoperative corneal pachymetric changes were noted before the procedure, after removal of epithelium, after RF-HPMC instillation, before and after UV irradiation. The mean of corneal pachymetric values were compared statistically.
resultsThe mean corneal pachymetry reduced from 415.72 ± 29.66 to 369.50 ± 23.45 μm after removal of the epithelium (p < 0.05). After the application of RF-HPMC solution the mean thinnest corneal pachymetry (TCP) increased to 412.89 ± 26.94 μm. Statistically significant increase was observed in TCP after saturation with RF-HPMC (p = 0.001). The mean corneal pachymetry before and after UVA irradiation was 419.86 ± 10.41 and 417.47 ± 8.25 μm, respectively (p > 0.05).
conclusionsIsotonic RF-HPMC lead to a significant increase in intraoperative mean TCP. RF-HPMC seems to be a favorable riboflavin option in keratoconus patients with thin corneas.
