Study finds, Morphological Changes after Lower eyelid Epible
This study aimed to determine the morphological changes in Asian lower eyelid epiblepharon patients after surgery.

The medical records of 59 patients who underwent lower eyelid epiblepharon repair were reviewed retrospectively. 89 patients who underwent strabismus surgery were set as the control group. The photographs for each group were analyzed based on the following factors: inferior half area (IHA) of the eye, eyelash angular direction (EAD), angle between the eyelashes and the cornea, marginal reflex distance 1 (MRD1) and marginal reflex distance 2 (MRD2).

--After surgery, the medial EAD changed, while the central and lateral EADs were unchanged.

--IHA increased from 36.33±9.78 mm3 to 43.06±10.57 mm3, and MRD1 increased from 1.92±0.99 mm to 2.50±0.93 mm, whereas MRD2 did not change.

--The mean angle between the eyelashes and the cornea increased from 39.64° to 72.19° immediately postoperatively, but had reduced to 58.75° 3 months later, followed by no further significant change at the 6-month and 9-month postoperative follow-ups.

In conclusion, there is morphological alteration of the eyelid following lower eyelid epiblepharon surgery, with an increase in the IHA and MRD1. Furthermore, contact between the eyelashes and the cornea occurred mostly in the medial section of the eyelid position, which everted and stabilized over the course of three months. As a result, at least three months of follow-up observations are required to accurately evaluate the surgical outcome.
