Course Summary

For a variety of reasons explored in this course, many patients gain advantages when their astigmatism is corrected with the use of contact lenses rather than eyeglasses. The types of astigmatism a patient might have, and the types of corrections are covered in this course to expand the knowledge of the contact lens dispenser. Multiple subjects are covered in the course, including lens needs assessment, design features, and other topics related to toric lenses. The course concludes with benefits, complications, and fitting considerations for the astigmatic patient.
