Course Number & Name:  OPH 204 Contact Lens II

Credit Hours:  3.0             Contact Hours:  3.0          Lecture:  3.0       Lab:  N/A             Other:  N/A

Prerequisites: Acceptance into the Vision Care program. Grade of “C” or better in OPH 201 and OPH 203
Concurrent Courses:  Grade of “C” or better in OPH 202

Course Description:   Fitting requisites, lens-cornea relationships, and the fitting of soft contact lenses are presented.  Emphasis on lens parameters, residual astigmatism and recognition of patient symptoms is fully presented.  Included are extended wear, scleral, cosmetic, and therapeutic lens fitting methods and a full understanding of the signs, symptoms and management of the Keratometer patient.  Instruction continues in the use of the Keratometer and Slit Lamp with the basic fitting philosophy of rigid and gas permeable contact lens fitting.  Refraction techniques are described and demonstrated.

<!– Course Goals: Upon successful completion of this course, students should be able to do the following:

  1. thoroughly explain the anatomy, physiology and topography of the eye as related to the wearing of contact lenses;
  2. name the different types of lens materials, differentiate between lens designs and interpret the parameters affecting the availability of contact lenses;
  3. accurately use the instrumentation for measuring the eye and contact lenses;
  4. discuss and interpret the conditions for fitting soft lenses and extended-wear lenses and the handling of a Keratoconus condition; and
  5. calculate contact lens’ powers, compensating for the change in vertex distance and fittings that are either flatter or steeper than the “K” reading.
