Which device is considered the best fitting method for fitting contact lenses?

• A. Radiuscope
• B. Keratometer
• C. Diagnostic lenses
• D. Pachymeter

Answer: (C)

The best fitting method for contact lenses involves using diagnostic lenses. This approach allows for direct assessment of how a trial lens fits on the patient’s eye, providing immediate feedback on comfort, movement, and positioning. By using diagnostic lenses, practitioners can simulate real-world lens wear conditions and note how various parameters such as curvature, diameter, and material interact with the patient's eye. Diagnostic lenses help in tailoring the lens characteristics to meet an individual's specific corneal shape, tear film quality, and visual needs, ensuring that the final selection provides optimal vision and comfort. This method permits adjustments based on direct observation and patient responses, facilitating a more personalized fitting experience compared to other methods. While radius scopes and keratometers provide important measurements of the eye's surface curvature, and pachymeters measure corneal thickness, they do not directly assess the fit of a contact lens. Therefore, while those instruments play a role in the fitting process by gathering relevant data, they are not as effective in providing the fitting experience that diagnostic lenses can offer.
