What’s inside:

  • Anatomy of the Eye: eyelids, orbit, extraocular muscles, tear film, the three tunics, the visual pathway, and the chambers of the eye

  • Supplemental Testing: autorefraction, keratometry, color vision, visual fields, cover tests, stereopsis, visual acuity, and accommodation

  • Biomicroscopy: using the slit lamp, illumination techniques, and filters

  • Keratometry and Corneal Topography: taking and verifying corneal measurements, and reading axial and tangential maps
