Abstract

Purpose

To evaluate the changes in visual acuity and astigmatism after epiblepharon surgery regarding preoperative age and astigmatism.

Methods

We retrospectively reviewed the charts of 37 patients with epiblepharon surgery. Preoperative best-corrected visual acuity and degree of astigmatism were obtained. Postoperative data were collected at 6 and 12 months.

Results

The mean patient age was 5.7 ± 2.5 years. In the 5-9 year-old group and ≤3D group, significant improvement of mean BCVA was demonstrated (p = 0.02, p = 0.039, respectively). In the cylinder groups, 1-2 D, 2-3 D, and ≤3D showed decreased mean astigmatism (p = 0.006, p = 0.034, p = 0.015, respectively).

Conclusions

Significant astigmatic reduction was found after surgical correction in epiblepharon patients with higher baseline astigmatism. These results suggest that an epiblepharon surgery should be considered in patients with a high levels of astigmatism.

Change of mean BCVA with age and astigmatism. There was a statistically significant improvement in BCVA in the 5 to <9 age group at 12 months postoperative (p = 0.002) and in the 3 D ≤ group at 6 and 12 months postoperative (p = 0.045, p = 0.039, respectively). ^* p < 0.05; Compared to baseline, Wilcoxon signed rank test.

Figure 2.

Change of mean astigmatism with age and astigmatism. There was a statistically significant decrease in astigmatism in the 5 to <9 age group at 6 and 12 months postoperative (p = 0.006, p = 0.004, respectively). In the astigmatism group, there was a decrease in 2 to <3 D at 6 and 12 months (p = 0.029, p = 0.034, respectively) and 1 to <2 D (p = 0.006), 3 D ≤ (p = 0.015) ^* p < 0.05; Compared to group at 12 months postoperative. baseline, Wilcoxon signed rank test.
