Impact of congenital lower eyelid entropion correction surgery on pediatric astigmatism

Objective: To evaluate the effect of congenital lower eyelid entropion surgery on refractive status and corneal astigmatism in children, and to explore surgical timing and visual rehabilitation. Methods: A total of 43 pediatric patients (43 eyes) aged 3-12 years who underwent entropion correction between June 2022 and June 2023 were included. Best-corrected visual acuity (BCVA), cycloplegic refraction and corneal topography were assessed preoperatively and at 1, 3, 6, and 12 months postoperatively. Statistical analyses included Spearman correlation, repeated-measures ANOVA, and nonlinear fitting. Results: < 0.001), and the proportion of amblyopic eyes decreased from 20.9% (9/43) preoperatively to 7.0% (3/43) at 1 year postoperatively. Conclusion: Surgical correction of congenital lower eyelid entropion significantly reduces astigmatism and improves visual acuity in children. Refractive status stabilizes by 3 months postoperatively, supporting early intervention to reduce amblyopia risk.
