Course Description
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 continue their clinical practice in a retail contact lens practice or the on campus clinic. They will complete their clinical skills under the direct supervision of a program approved licensed eyecare professional. A one-week on-campus (laboratory and clinical) instruction component may be required 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
    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. Describe and record tonometry measurements and intraocular pressure
