Course Description
This course provides learning opportunities for students to apply knowledge and skills acquired from related theory and laboratory courses to the contact lens dispensary. Students will be placed in the campus vision centre or pre-approved practicum locations where they will simulate a contact lens practice. They will complete their contact lens dispensing skills under direct supervision of the course instructor or program-approved licensed eyecare professional. Students will perform all duties pertaining to efficient operation of a contact lens practice including patient booking, contact lens fitting and analysis, the steps involved in an automated sight test including over-refraction, and patient education on lens care and handling. Contraindications to the automated sight testing will be acquired through studying the Professional Standards of Practice. A one-week on-campus (laboratory and clinical) instruction component will take place near the end of the semester to complete the course.

Learning Outcomes

Upon successful completion, the student will be able to:

  1. Obtain a general history from the patient through discussion
  2. Use instrumentation and other provisional methods to determine appropriate soft contact lens type and design
  3. Describe the types and functions of equipment necessary in the process of refraction in the determination of refractive error
  4. Describe the types and functions of equipment necessary to determine intraocular pressure
  5. Interpret patient refractive error and keratometry readings
  6. Discuss soft contact lens options with the patient as related to the ocular status and prescription
  7. Conduct a diagnostic soft lens evaluation
  8. Order appropriate contact lens parameters for a patient
  9. Educate the patient in soft lens insertion / removal procedures, lens care and hygiene
  10. Determine the patient’s subjective responses to soft contact lens wear
  11. Make necessary modifications to improve lens fit
  12. Reinforce to the patient the necessity of follow-up examination
  13. Apply concepts of boutique dispensing to contact lens and eyeglass dispensing
