Overview

Course Description
This course will provide students the knowledge of Anatomy and Physiology of the eye in relation to contact lens fitting. It will provide the skills of instrumentation in the fitting of contact lenses, the process of refractive error determination, the conversion and verification of prescriptions, and the examination of the relationship between contact lens fit, corneal health and residual refractive error. It provides students the ability needed to evaluate suitability for contact wear, by patient ocular history and examination. It will provide the student the ability to design the appropriate contact lens parameters, to select the appropriate material, to train the patient on proper handling technique, lens care and hygiene. It will identify refractive surgeries, the measurement of intraocular pressure and related professional standards of practice.
