B. Refractive Errors


Objectives:

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