Overview

Course description
This course provides learning opportunities in contact lens and optical technologies at an advanced level in simulated laboratory environment. Students will fit spherical, toric, and presbyopic refractive errors for soft contact lenses, and spherical refractive errors for gas permeable contact lenses.

Learning activities

Application / calculation exercises in laboratory

Laboratory assignments

Independent study

Means of assessment

Evaluation will be carried out in accordance with the Douglas College Evaluation Policy. The instructor will present a written course outline with specific evaluation criteria at the beginning of the semester. Evaluation will be based on the following:

  • Professionalism, preparedness, and attendance 0-5%
  • Assignments 10-20%
  • Term tests  45-60%
  • Final exam 20-30%
Learning outcomes

Upon completion of this course, successful students will be able to:

  • demonstrate the use of instruments for soft and gas permeable contact lens fitting and analysis to meet the criteria for a well-fitting contact lens
  • demonstrate the steps of a typical soft or gas permeable lens pre-fit evaluation, diagnostic fitting, and post-fit evaluation
  • demonstrate proper soft and gas permeable lens care and hygiene
  • access online pharmaceutical information on ocular medications
  • perform gas permeable lens parameter modifications
  • perform an over-refraction process in a typical contact lens fitting
  • describe and perform an automated refraction procedure using objective and subjective means
  • describe and perform the steps in an automated refraction assessment
  • quantify refractive error using objective and subjective means
  • desribe the automated refractive error assessment within the context of the overall eye health examination.
  • incorporate cultural safety and humility in opticianry practices
  • discuss the history and ongoing effects of colonization on the Indigenous Peoples of Canada, including disparities of power in patient-provider relationships
  • identify situations where informed consent may be problematic and take appropriate steps to ensure patient understanding
  • adhere to infection prevention and control measures established by jurisdiction and national regulatory bodies
  • recognize significant signs and symptoms in relation to the patient's eyes to identify the need for referral
