B. Refractive Errors
Objectives:
- Apply an understanding of refraction to explain the method by which the Cornea (and less so the lens) focuses light onto the retina.
- Describe the physical underpinnings of myopia, hyperopia and astigmatism as they relate to the diameter of the globe and the shape of the cornea.
- Have a basic understanding of the various procedures to correct refractive error.
