“…Critically, the correlation between reduced corneal staining grade and decreased total HOAs may inform the timing of surgery in children without specific visual disturbance and photopobia. [32] However, the present study found that coma and trefoil were significantly increased after epiblepharon repair surgery at the first f/u, and normalized by the second f/u rather than being decreased, supporting previous results. [32] In fact, we found that only SA decreased at the second f/u (especially in G3).…”

Objective: To investigate changes in corneal low and high order aberrations (LOA and HOA), which cause visual disturbances after lower eyelid epiblepharon repair surgery. Methods and analysis: This was a retrospective, cross-sectional study, which included 108 eyes from 54 patients. Wavefront analyses for calibrated LOAs and HOAs (root mean square, coma, three-piece aberrations [Trefoil], secondary astigmatisms, and spherical aberrations [SA]) were performed via a Galilei G4 Dual Scheimpflug Analyzer preoperatively, at the first and second follow-ups (f/u), and at G1, G2, and G3 (<45 days, 45-75 days, and >75 days post-surgery). Several risk factors (age, sex, body mass index, and corneal keratitis presence) were assessed. Results: In LOAs, flat keratometer (K) and axis values decreased significantly from baseline at the first f/u. At the second f/u, mean K and axis decreased. In HOAs, coma and trefoil increased from baseline at the first f/u and normalized by the second f/u. SA decreased at the second f/u and in G3. The various risk factors did not affect postoperative outcomes, axis, and secondary astigmatisms. After correcting for risk factors, at the first f/u, cylinder, coma, trefoil, and SA increased significantly from the baseline, while axis and flat K decreased. At the second f/u, cylinder increased, while axis and mean K decreased significantly from the baseline. Conclusion: Epiblepharon repair surgery may impact axis changes. Flat K, coma, and trefoil may be affected by mechanical force changes immediately following surgery. Mean K and SA may change with cornea state changes during healing.

“…In previous studies on changes in HOA after epiblepharon surgery, Lee et al 8 reported a significant decrease in total HOA and secondary astigmatism 1 month after epiblepharon surgery, in the 6.0 mm optical zone. They reported a significant decrease in total HOA, coma, tetrafoil, and secondary astigmatism 3 months after surgery.…”

Purpose: To investigate changes in corneal anterior high-order aberration (HOA) and contrast sensitivity (CS) before and after epiblepharon surgery. Methods: A retrospective observational analysis of the degree of corneal erosion, HOAs and CS was conducted in the OD and OS, respectively, before and after epiblepharon surgery. The correlations between corneal erosion, HOAs, and CS were analyzed. Results: Forty-nine patients were included in the study. Among the anterior HOAs, total HOA, coma, and trefoil showed significant improvement after surgery (P = 0.003, P = 0.009, and P = 0.018, respectively). In the CS test, there was a significant improvement in CS after surgery at 1.1 cycles per degree (cpd) under photopic conditions, regardless of glare. Preoperative correlation analysis between HOAs and corneal erosion showed a significant positive correlation with total HOA (P = 0.001) and coma (P = 0.001). Preoperative correlation analysis between CS and corneal erosion showed a significant negative correlation at 1.1 cpd with glare under photopic conditions (P = 0.049). A negative correlation was also observed between CS under mesopic and photopic conditions and total HOA both before and after surgery. Conclusion: Significant improvement in corneal anterior HOAs and CS at 1.1 cpd under photopic conditions was observed after epiblepharon surgery. Total HOA of anterior cornea showed a negative correlation with CS. A decrease in HOAs and recovery of corneal erosion after epiblepharon surgery will help improve CS.

“…Noda et al reported that mild epiblepharon can be treated with a conservative approach, after which the condition can spontaneously improve over time [ 14 ]. However, severe corneo-ciliary touch can cause prompt corneal injury and can later result in astigmatism and even higher-order aberrations [ 15 , 16 ]. In this context, Tan P indicated that establishing a common objective system for grading epiblepharon is advisable to help determine the appropriate indications for surgery and has introduced studies related to epiblepharon grading [ 17 – 19 ].…”

To report the experience and advantageous effects of high-frequency radio wave electrocautery in modified Hotz operations for epiblepharon, We reviewed the records of all pediatric patients who underwent a modified Hotz operation with the use of high-frequency radio wave electrocautery (Ellman Surgitron Dual Frequency RF S5; Ellman International, Inc, Hewlett, NY) for epiblepharon between March 2016 and September 2019 at Korea University Guro Hospital. We evaluated the success rate, complications, recurrence rate and degree of satisfaction of our technique. Information from the medical records was collected, including demographics, ocular symptoms, severity of keratopathy, operation time, success/recurrence rate, and complications. 133 patients (98.52%) showed good correction of epiblepharon without complications or unpleasant cosmetic problems during 3 months of median follow-up period. Two patients (1.48%) showed recurrent corneociliary touch, but the degree was very mild and re-operation was not performed. One patient showed mild ectropion on his left lower eyelid, but the patient recovered well without operation. For complications, suture abscess and granulation were the most common, 3 cases in each, but all of those were temporary and resolved with conservative management. The approach with electrocautery for epiblepharon allows precise and fast incision of the lower eyelid, little bleeding, and minimal scarring. Surgical outcomes associated with the modified Hotz operation with electrocautery were consistent with previous studies.
