Refractive status and ocular biometric parameters in children undergoing the levator muscle-conjoint fascial sheath complex suspension.
Article in BMC ophthalmology, 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 evaluate the effect of the levator muscle-conjoint Fascial Sheath Complex Suspension on ocular biometric parameters and refractive status in children with congenital blepharoptosis.
methodsWe reviewed the clinical records of 68 patients with congenital blepharoptosis who attended our hospital from 2021 to 2023 and underwent ptosis surgery with detailed examination. The changes of corneal topography and refractive characteristics before and 1 month, 3 months, 6 months after surgery were compared and analyzed.
resultsBefore surgery, ptosis eyes had statistically significant flatter flat keratometry (P = 0.015), thicker subfoveal choroidal thickness (P = 0.021), higher astigmatic magnitude(P = 0.006) than non-blepharoptosis eyes. The 1-month postoperative steep keratometry and the astigmatic magnitude were significantly higher than the preoperative values in unilateral ptosis (P = 0.032, P = 0.014), without affecting astigmatic power vectors and central corneal thickness (P > 0.05); The astigmatic magnitude at 3 months after surgery were higher than the preoperative values in unilateral ptosis (P = 0.042). In all patients, the postoperative change of astigmatic magnitude was greatest in severe ptosis.
conclusionsPtosis repair surgery for congenital ptosis seems to cause increase of steep K value and astigmatism over early postoperative period but no refraction alteration over the long-term postoperative period. A significant myopic shift was observed at the 6-month postoperative follow-up in severe unilateral ptosis.
