OPT 222 Basic Contact Lenses
Anatomical and physiological considerations in the application of contact lens correction. Material and modality considerations in the fitting of contact lenses. Lifestyle and kinesthetic issues affecting candidacy for contact lens wear. Basic design and manufacturing of rigid and hydrogel contact lenses. Parameter determination based on clinical measurements of corneal size, corneal curvature, refraction and residual astigmatism. Effective power changes. Iatrogenic implications and anterior segment disease potential in the application of contact lenses. Appropriate and effective use of contact lenses for the treatment of all ametropias including myopia, hyperopia, astigmatism and presbyopia. Effective management and follow-up of the contact lens patient. A clinical approach to contact lens use will be used. Emphasis on troubleshooting problems related to contact lens wear and determining appropriate strategies for remediating contact lens-related signs and symptoms. Verification of parameters of soft and rigid contact lenses to include base curve, diameter, power, optic zone diameter, edge design and integrity, peripheral curves and quality of the surfaces. Radiuscopy, use of reticule, polish and modification of rigid contact lenses.
