Contact Lens Fitting and Assessment
Patients that wear contact lenses require some special care by our doctors and staff. In addition to the eye exam, the doctor will provide services that are specific to the wearing and fitting of contact lenses. The doctor will evaluate the cornea for abnormalities that are specifically related to contact lens wear including corneal edema, corneal infiltrates, corneal neovascularization, and endothelial cell loss. The cornea will also be assessed for signs of improper contact lens fitting. Corneal diameter will be measured and compared to current contact lens diameter to determine if any adjustment in lens size is needed. Corneal surface curvature as well as the amount and axis of astigmatism will be analyzed to see if any change in contact lens base curvature is warranted.
With the results of those assessments, your eye doctor can provide a contact lens prescription that is the right fit for your eyes. An eyeglass prescription is no substitute for a contact lens exam because the two are very different. An eyeglass prescription measures for lenses that are positioned approximately 12 millimeters from your eyes; whereas a contact lens prescription measures for lenses that sit directly on the surface the eye. An improper fitting or prescription of contacts can damage the health of the eyes.
