Abstract

Purpose
To evaluate the changes in corneal astigmatism before and after epiblepharon correction surgery with a Scheimpflug camera.
Methods
From April, 2019, to June, 2020, 48 eyes of 24 patients underwent epiblepharon correction surgery. The patients were divided into two subgroups by age and their best corrected visual acuity (BCVA) and corneal anterior and posterior astigmatism were compared before and after correction surgery.
Results
There was no difference in BCVA after the correction surgery. To assess the changes in the keratometric value and astigmatism after epiblepharon surgery, a Scheimpflug camera was used. The anterior flat and mean keratometry changed from 42.10 ± 1.46 to 42.43 ± 1.10 D (p = 0.035) and from 42.97 ± 1.26 to 43.21 ± 1.15 D (p = 0.012), respectively, while the posterior corneal astigmatism changed from 0.44 ± 0.31 to 0.35 ± 0.17 D (p = 0.047). There were no significant changes in steep keratometry (p = 0.191) or anterior corneal astigmatism (p = 0.126).
Conclusions
There were significant changes after epiblepharon correction surgery in anterior keratometry reading and posterior corneal astigmatism.
