Facial Recognition Pattern before and after Lower Eyelid Blepharoplasty: An Eye Tracking Analysis

Area of Science:

• Ophthalmology
• Plastic Surgery
• Cognitive Science

Background:

• Facial aesthetics significantly influence social perception and attractiveness judgments.
• Understanding how the brain processes facial features is crucial in cosmetic surgery outcomes.
• Eye tracking offers objective insights into visual attention and perception.

Purpose of the Study:

• To investigate changes in eye movement patterns before and after bilateral periorbital cosmetic surgery.
• To determine how aesthetic preferences and surgical alterations affect facial feature recognition sequences.
• To explore the relationship between visual attention patterns and the perception of beauty.

Main Methods:

• Utilized eye tracking technology to record participants' gaze patterns.
• Analyzed visual scan paths on preoperative and postoperative images of patients undergoing periorbital cosmetic surgery.
• Correlated eye movement sequences with subjective aesthetic liking.

Main Results:

• The sequence of facial feature recognition shifted from periorbital-nose-perioral preoperatively to nose-periorbital-perioral postoperatively.
• Aesthetic liking significantly influenced the order in which facial features were recognized.
• Alterations in facial features demonstrably impacted the sequence of visual attention.
• Aesthetically pleasing features were viewed for shorter durations and appeared later in the scan path.

Conclusions:

• Facial cosmetic surgery alters visual processing and attention patterns.
• The perception of beauty and individual aesthetic preferences guide eye movement strategies when viewing faces.
• Eye tracking provides valuable data for understanding the perceptual impact of cosmetic procedures.
