The Effect of Lower Eyelid Blepharoplasty on Corneal Biomechanical Parameters.
Article in Korean journal of ophthalmology : KJO, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 effect of lower eyelid blepharoplasty (LEB) surgery on corneal biomechanical parameters before and 4 months after the procedure.
methodsIn this prospective longitudinal study, corneal biomechanical parameters measured by Corneal Visualization Scheimpflug Technology device were evaluated before and 4 months after LEB surgery.
resultsThe study included 19 eyelids of the right eyes of 19 patients who underwent LEB, with a mean age of 49.0 ± 10.1 years (range, 37-72 years). Four months after the procedure, significant increases were observed in the first applanation time (p = 0.007), second applanation time (p < 0.001), highest concavity time (p = 0.004), intraocular pressure (p = 0.009), and biomechanical-compensated intraocular pressure (p = 0.007). In addition, the absolute value of highest concavity delta arc length and stress-strain index showed a significant decrease after the LEB (p = 0.021 and p = 0.037, respectively). Other corneal biomechanical parameters did not show significant differences following the LEB procedure (p < 0.05).
conclusionsThe resection and repositioning of the fat pockets in LEB lead to biomechanical changes of the cornea in the direction of increasing corneal stiffness.
