Understanding the salient features that draw focus when assessing aesthetics is important for maximizing perceived outcomes. Eye-tracking technology provides an unbiased method for determining the features that draw attention when evaluating aesthetic plastic surgery. This study aimed to characterize viewing patterns of plastic surgery patients and laypeople when assessing facial cosmetic procedure images.
Twenty women who previously underwent cosmetic procedures and twenty women without a history of cosmetic procedures were shown sixteen pairs of preprocedure and postprocedure images of patients who underwent laser resurfacing or lip augmentation. Image pairs were randomized to whether preprocedural or postprocedural images came first. Participants viewed each image until they decided upon an aesthetic rating (scored 1-10), while an eye-tracking device recorded participants' gaze.
The patient group's average ratings were 8.2% higher for preprocedural images and 13.3% higher for postprocedural images (P < 0.05 for both). The patient group spent 20.4% less time viewing images but spent proportionally more time evaluating the relevant features of each procedure (41.7% vs 23.3%, P < 0.01), such as the vermillion border of the upper lip, labial commissure, or periorbital region (P < 0.05 for each). For both groups, the most common site of first fixation was the nose for laser resurfacing images (26.6%) and the labial commissure for lip augmentation images (37.7%). Both groups spent more time fixated on nasolabial folds, marionette lines, and the periorbital region when viewing pre-laser resurfacing images than postprocedural images. Overall, each group had similar viewing patterns for time to first fixation on and frequency of fixations for a particular feature.
Women who previously underwent cosmetic procedures view postprocedural images more favorably and require less time to assess images, likely related to familiarity with aesthetic procedures. These women spend more time fixated on relevant features, such as the vermillion border of the upper lip, the labial commissure, and the periorbital region, than the control group. Notably, each group spent less time focused on regions associated with wrinkles, such as the marionette and periorbital areas in post-laser resurfacing images, suggesting that the procedure reduces attention-drawing features in these areas.
了解在评估美学时吸引注意力的显著特征对于最大化感知效果很重要。眼动追踪技术提供了一种无偏差的方法来确定在评估美容整形手术时吸引注意力的特征。本研究旨在描述整形手术患者和普通人在评估面部美容手术图像时的观看模式。
向20名曾接受过美容手术的女性和20名无美容手术史的女性展示16对接受激光换肤或隆唇手术患者的术前和术后图像。图像对随机决定术前或术后图像先出现。参与者观看每张图像，直到他们决定给出美学评分（1 - 10分），同时眼动追踪设备记录参与者的注视情况。
患者组对术前图像的平均评分高8.2%，对术后图像的平均评分高13.3%（两者P < 0.05）。患者组观看图像的时间少20.4%，但按比例花更多时间评估每个手术的相关特征（41.7%对23.3%，P < 0.01），如唇红缘、口角或眶周区域（每个P < 0.05）。对于两组，首次注视的最常见部位，对于激光换肤图像是鼻子（26.6%），对于隆唇图像是口角（37.7%）。与术后图像相比，两组在观看激光换肤术前图像时，花更多时间注视鼻唇沟、木偶纹和眶周区域。总体而言，每组在首次注视特定特征的时间和注视频率方面有相似的观看模式。
曾接受过美容手术的女性对术后图像评价更高，评估图像所需时间更少，这可能与对美容手术的熟悉程度有关。这些女性比对照组花更多时间注视相关特征，如唇红缘、口角和眶周区域。值得注意的是，两组花在与皱纹相关区域的时间都较少，如激光换肤术后图像中的木偶纹和眶周区域，这表明该手术减少了这些区域吸引注意力的特征。
