Analysis of corneal wavefront aberrations and corneal densitometry in eyes with epithelial basement membrane dystrophy.

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 investigate wavefront aberrations, as well as corneal optical densitometry (COD), in eyes with epithelial basement membrane dystrophy (EBMD) and the influence on visual acuity.
methodsIn this cross-sectional study, 70 eyes of 70 patients (mean age 55.9 ± 14.0 years) with the central cornea involving EBMD were compared to 50 healthy eyes of 50 patients (mean age 58.8 ± 14.1 years) serving as controls. Wavefront aberrations of the anterior corneal surface and the total cornea were measured with the Pentacam AXL (Oculus Optikgeräte GmbH, Wetzlar, Germany), and calculated for the 6 mm central corneal zone. In addition, the COD (corneal light backscatter measured in grey scale units) of the anterior 120 µm of the central 0-2 mm, 2-6 mm, and 6-10 mm of the cornea was evaluated. Corrected distance visual acuity (CDVA) was correlated with wavefront aberrations and COD using Spearman correlation analysis.
resultsEBMD resulted in significant higher peak-to-valley (PTV; median: 15.0 [interquartile range: 9] µm), square root of the sum of the squared higher-order aberrations (RMS-HOA; 0.77 [0.52] µm), astigmatism (1.06 [1.04] µm), coma (0.41 [0.44] µm), and trefoil (0.28 [0.40] µm) (all p ≤ 0.01). A moderate correlation was found especially between CDVA and PTV as well as RMS-HOA. EBMD led to a statistically significant higher COD (p < 0.01) in the central corneal 6-mm and correlated moderately with CDVA outcomes.
conclusionsOur study revealed a significant correlation between elevated wavefront aberrations and backscattering in eyes affected by epithelial basement membrane dystrophy. While COD demonstrates potential for diagnostic purposes, additional studies are necessary to ascertain its specificity and distinguish EBMD from other ocular surface disorders.
