Summary
Pediatric epiblepharon surgery improved corneal astigmatism and surface regularity. Both incisional and nonincisional methods enhanced corneal topography, with incisional surgery showing significant astigmatism improvement.
Area of Science:
- Ophthalmology
- Corneal Surgery
- Pediatric Ophthalmology
Background:
- Pediatric lower-lid epiblepharon can affect corneal morphology.
- Surgical correction is necessary to prevent potential visual complications.
Purpose of the Study:
- To investigate corneal morphology changes after pediatric lower-lid epiblepharon surgery.
- To compare incisional versus nonincisional surgical techniques using topographic modeling.
Main Methods:
- A randomized controlled trial included 89 eyes from 50 children (3-12 years) with moderate epiblepharon.
- Patients underwent either incisional (modified Hotz) or nonincisional surgery.
- Corneal topography analysis (TMS-5®) assessed surface regularity index (SRI), Standard Deviation of Corneal Power (SDP), Irregular Astigmatism Index (IAI), and corneal astigmatism (CYL).
Main Results:
- Both surgical methods significantly improved corneal astigmatism parameters (p < 0.01).
- The incisional group showed a significant mean change in corneal astigmatism (-0.34 ± 0.96 D, p = 0.012).
- Postoperative suspicion rates for keratoconus decreased significantly (p < 0.01).
Conclusions:
- Both incisional and nonincisional epiblepharon surgeries improve corneal surface smoothness and refractive power variability.
- Corneal astigmatism showed significant improvement, particularly with the incisional approach.
- Epiblepharon patients may exhibit keratoconus-like topography, especially when assessed with the Keratoconus Severity Index (KSI).
