Clinical in Contact Lenses and Optical Technologies II

Overview

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 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.

Learning outcomes

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

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

Textbook materials

No textbooks required. A student practicum manual will be provided by the instructor at the beginning of the semester.
