The effect of ptosis surgery on corneal topography and aberrometry.

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 evaluate the corneal topography and aberrometry and their changes following ptosis surgery in patients suffering from unilateral congenital blepharoptosis.
methodsThe study included 15 eyes of 15 patients with unilateral congenital blepharoptosis who underwent surgical correction through anterior levator resection. Shack-Hartmann wavefront sensor was employed to assess Zernike coefficients and root-mean-square. Computerized corneal topography, Orbscan and aberrometry were measured pre-and 3 months post-surgery in the healthy and ptotic eyes. Aberrometric changes were compared between patients with more than one diopter of astigmatism and subjects with less amount of astigmatism. Data were analyzed using the SPSS version 16.
resultsFollowing anterior levator resection, the amount of astigmatism decreased. However, the difference was not statistically significant. Changes in topographic indices were not statistically significant. Regarding tomographic indices, the change in minimum keratometry was significant. The amount of change in total higher-order aberrations (HOAs) was not statistically significant. However, there was a decrease in the amount of third-order aberrations (vertical coma and vertical trefoil) which was statistically significant for vertical coma (-0.002 ± 0.001 vs. -0.08 ± 0.02 µm,
conclusionSurgical correction of ptosis could reduce the ocular aberrations, despite no significant change in astigmatism. Nonaxial high-order aberrations are mostly affected probably due to the meridional effect of ptosis on the cornea.
