Defining Ideal Double Eyelids With a Morphometric Analysis in Asians

Area of Science:

• Oculoplastic surgery
• Aesthetic surgery
• Facial aesthetics

Background:

• Double eyelids are a significant feature in facial aesthetics.
• Quantitative and morphological data on ideal double eyelids are lacking.

Purpose of the Study:

• To determine the optimal height and morphological characteristics of ideal double eyelids.
• To address the research gap in the quantitative evaluation of double eyelid aesthetics.

Main Methods:

• Participants rated 9 images (1 single, 8 double eyelids) with varying pretarsal show heights and shapes.
• Scoring ranged from 1 (least attractive) to 5 (most attractive).
• Data were analyzed by demographics, and aesthetic metrics were calculated.

Main Results:

• A 2-mm double eyelid fold was rated most attractive, followed by 1 mm, 3 mm, and single eyelids (0 mm).
• Significant morphological differences were noted for 3-mm and 4-mm pretarsal shows.
• Gender was the most influential demographic factor in aesthetic preference.

Conclusions:

• The study identified optimal double eyelid heights and morphology, validating previous findings for 2-mm folds.
• Results provide crucial data for surgical planning in upper blepharoplasty and other periocular procedures.
