Eye-tracking technology objectively measures the visual focus of subjects when assessing aesthetics. Identifying attention-drawing features can assist in improving patient satisfaction and perceived outcomes. Using eye-tracking technology, we characterized visual gaze patterns among plastic surgery patients versus laypeople when assessing pre- and post-abdominoplasty images.
Sixteen pairs of pre- and post-abdominoplasty images in AP and lateral views were shown to twenty women with and twenty women without a cosmetic procedure history. An eye-tracking device recorded visual gaze data as participants assessed the aesthetic value of the images.
The patient group spent 22.6% less time evaluating images (p < 0.05) but spent proportionally more time fixated on features of interest: the umbilicus (25.6% of their average viewing time vs 11.6%, p < 0.001), scar line (13.2% vs 5.1%, p < 0.001), and abdominal curvature (7.6% vs 3.6%, p < 0.001). Both groups most commonly first fixated on the umbilicus and abdominal curvature for AP and lateral views, respectively. The patient group’s average increase in aesthetic rating between pre- and post-procedural images was 30.4% higher than the lay group (p < 0.05). No correlation was noted between aesthetic ratings and time spent viewing the areas of interest.
Females who previously underwent cosmetic procedures are more favorable, faster, and focused reviewers of abdominoplasty images, fixating more on relevant anatomy and features than their peers. New patients may benefit from an eye-tracking-based assessment to align procedural planning and consultation with the anatomic areas they visually fixate upon.
