Stellest lenses require precise measurements and fitting to minimize visual complaints and unnecessary remakes. This course examines common causes of Stellest remakes, including pupillary distance, fitting position, frame fit, vertex distance, and prescription variables. Participants will review measurement best practices, pupilometer calibration, frame adjustments, and troubleshooting techniques. Through real-world scenarios, opticians will learn strategies to evaluate visual complaints, improve measurement consistency, reduce avoidable remakes, and achieve successful first-pair outcomes.
