The purpose of this study was to test the validity and reliability of the International Council of Ophthalmology’s Ophthalmology Surgical Assessment Rubric for phacoemulsification (ICO-OSCAR:phaco). The tool was adapted from a previously published tool for assessing phacoemulsification; was then reviewed by 12 international content experts whose comments were incorporated to ensure validity; finally, 10 expert cataract surgery teachers graded six recorded phacoemulsification surgeries to investigate the tool’s reliability.

The coefficient alpha statistic (a measure of reliability/internal consistency) for the ICO-OSCAR:phaco as a whole was 0.92, and 17 of its 20 dimensions had alpha coefficients greater than 0.70. Authors conclude that the ICO-OSCAR:phaco is a valid and reliable assessment tool that could be applied internationally to satisfy the global need of new instruments to comply with emerging trends in ophthalmic education.
