Refractive Conditions & Automated Refraction (OPTC 2430)

In the beginning of this course students will review the principles of refraction before discussing
the pathophysiology of refractive conditions including astigmatism, anisometropia, and
aniseikonia. In the second part of this course students will learn the automated refraction process
and discuss its limitations, contraindications, and referrals before applying their knowledge
of the process in the lab. This course builds on knowledge gained in OPTC 1110 Anatomy and Physiology of the Eye, and OPTC 1130 Foundations of Optics.
