Spherical GP Fitting and Problem-Solving

The fitting of GP lenses is actually quite straightforward. This process begins with presenting the benefits of GPs and then presenting GPs in a realistic, but non-threatening manner. Avoid terms such as "discomfort," "pain," and "hurt." GPs can be presented in the following way: "You will experience some initial lens awareness due to the lid sensing the lens movement on the eye. This will go away over time." The use of a topical anesthetic during the fit will help the patient ease into the adaptation process.

Fitting Pearls

• Present GPs in a non-threatening manner
   
• Use topical anesthetic
   
• Use diagnostic lenses (contact CLMA member laboratory for assistance if necessary)
   
• Apply fluorescein to evaluate the fitting relationship
   
• Use yellow filter over observation system of slit lamp to enhance fluorescein pattern

Fitting Tip Checklist

Any design changes made to affect the GP fitting relationship should be significant in nature, such as listed on the checklist.
