Course description
This course provides theory and interpretation of contact lens fitting procedures at an advanced level. It provides the skills to complete the procedure of fitting contact lenses by implementing patient pre-fit evaluation, instrumentation, measurements, trial lens fitting, and post-fit evaluation. It provides students the abilities needed to interpret and apply fitting techniques of specialty contact lenses for difficult visual and / or corneal abnormalities and to identify surgical alternatives available. The course provides basic skills necessary for managing a contact lens practice for effective patient record keeping, relationships and recall systems. It promotes a comprehensive knowledge of professional standards of practice.
