مستخلص: Objective: To evaluate the potential of motion analysis as a discriminator of surgical skill during intraocular surgery.
Methods: Twenty-four subjects were divided into 3 groups (n = 8 each) based on the number of completed phacoemulsification procedures: novice (n < 10), intermediate (n = 10-150), and expert (n > 150). The Qualisys motion-capture system obtained data from the surgeons performing (1) corneal wound construction (incision), (2) continuous curvilinear capsulorrhexis (CCC), and (3) phacoemulsification lens extraction on artificial eyes. The main outcome measures were time, overall path length, and total number of movements. Statistical significance was set at P < .05.
Results: For the incision task, significant differences between the levels of experience were found for time (P = .001), number of movements (P = .001), and path length (P = .05). For the CCC task, significant differences were found between groups for time (P = .03) and number of movements (P = .03), but not for path length (P = .08). For the phacoemulsification task, significant differences were found between the 3 groups for time (P = .04), path length (P = .02), and number of movements (P = .04).
Conclusions: Motion analysis differentiated between surgeons with varying levels of experience performing phacoemulsification tasks, thus demonstrating construct validity. This technique may be useful in the objective quantitative measurement of microsurgical skill with potential applications for training and research.

مستخلص: Objective: To evaluate motion analysis as a discriminator of ophthalmic plastic surgical skill between surgeons of varying experience.
Methods: Thirty subjects were divided into 3 groups based on surgical experience: novice (< 5 performed procedures; n = 10), intermediate (5-100 procedures; n = 10), and expert (> 100 procedures; n = 10). Detailed 3-dimensional motion data from surgeons performing 2 oculoplastic surgical tasks on a wet laboratory skills board were obtained using the Qualisys motion capture system. The first task was a deep 3-1-1 suture. The second was skin closure with a continuous suture. The main outcome measures were time, overall path length, and total number of movements. Kruskal-Wallis analysis was performed to evaluate statistical significance.
Results: Highly significant differences were found during the skin closure task between all groups for mean time (P = .002), overall path length (P = .002), and number of movements (P = .001). For the deep stitch, highly significant differences were also found for time (P < .001), path length (P < .001), and number of movements (P < .001).
Conclusions: Motion analysis, using this technology, was able to differentiate between surgeons of varying experience performing oculoplastic tasks, thus demonstrating construct validity. This technique may be useful in the objective quantitative measurement of oculoplastic skill, with potential applications for training and research.
