Clinical in Contact Lenses and Optical Technologies II

Course Code: DOPT 2211
Faculty: Science & Technology
Department: Dispensing Optician
Credits: 5.0
Semester: 15
Learning Format: Lecture, Clinical
Typically Offered: Winter
course overview

This course provides learning opportunities in contact lenses and optical technologies at an advanced level. Students will apply knowledge and skills from related theory and laboratory courses to the clinical dispensary. Students will complete their clinical practice in the on-campus contact lens lab. They will complete their clinical skills under the direct supervision of a licensed eye care professional. There will be a continued focus on the technologies related to independent automated refraction.

Methods of Instruction

  1. Student and assigned group members are to complete 120 hours of clinical contact lens fitting under the supervision of the course instructor or lab technician
  2. Lectures
  3. Independent study of courseware
  4. Completion of field assignments

Means of Assessment

The course evaluation will be consistent with Douglas College evaluation policy.  This is a mastery course.

Learning Outcomes

Upon successful completion, the student will be able to:

  1. Obtain a general history from the patient
  2. Determine what diagnostic activities must be conducted to complete an evaluation
  3. Use instrumentation and other provisional methods to determine appropriate gas permeable contact lens types and designs
  4. Interpret patient refractive error, keratometry readings, and automated corneal topography
  5. Discuss contact lens options with the patient
  6. Conduct a diagnostic evaluation of a contact lens using reality and simulation software
  7. Educate the patient on lens insertion, removal, and care
  8. Conduct a contact lens follow-up examination
  9. Make necessary modifications to improve contact lens fitting characteristics
  10. Verify visual acuity by over-refraction
  11. Perform the automated sight testing procedure
  12. Perform low vision assessment and dispense low vision aids
