To present a structured tool to assess ophthalmic plastic surgical skill and to determine its face and content validity. A 1-page structured subjective evaluation form was developed to evaluate a resident's oculoplastic surgical skill while performing lateral tarsal strip surgery. The tool consisted of generic task components and global indices evaluated using a 5-point Likert scale. A survey was conducted among a panel of highly experienced oculoplastic surgeons to establish face and content validity of the tool. All feedback was considered and, if feasible, was used to amend the tool. There was more than 90% agreement among the highly experienced oculoplastic surgeons regarding the content and weighting of each assessment component. The final format of the tool is divided in 9 task-specific indices, based on the lateral tarsal strip procedure, and 9 global indices which, after assessment, appraisal, and amendment by our expert panel, demonstrates face and content validity. The Ophthalmic Plastic Surgical Skills Assessment Tool is a structured, quantitative instrument designed to aid in the oculoplastic surgical evaluation and training of residents.
