Oiginal Studies

Purpose: To produce an internationally valid tool to assess skill in performing trabeculectomy surgery.

Methods: A panel of 5 experts developed a tool for assessing trabeculectomy surgery by using a modified Dreyfus scale of skill acquisition and providing descriptors for each level of skill for each category. The tool was then reviewed by a panel of 10 international content experts for their constructive comments, which were incorporated into the final rubric tool.

Results: A final rubric, incorporating the suggestions of the international panel, published here as the ICO-OSCAR: Trabeculectomy.

Conclusions: The tool ICO-OSCAR: Trabeculectomy has content and face validity. It can be used internationally to assess trabeculectomy surgery skill. Predictive and construct validity, and reliability are yet to be determined.
