Which fitting guide is commonly used for soft contact lenses?

The lens manufacturer's fitting guide is the accepted and most reliable source for fitting soft contact lenses. This guide provides specific parameters, recommendations, and fitting techniques that are tailored to the unique characteristics of the manufacturer's lenses. Each lens design can have different requirements based on material, thickness, curvature, and diameter, which are critical in ensuring proper fit and optimal vision correction.

Using the lens manufacturer's fitting guide helps practitioners account for variations between different lens brands and styles, such as differences in water content, oxygen permeability, and surface characteristics. This leads to better fitting outcomes, enhanced comfort for the patient, and reduced risk of complications such as corneal edema or discomfort while wearing the lenses.

While other sources, like personal notes or generic FDA guidelines, might provide helpful information, they lack the specific details that the manufacturer's guide offers. The national optician code is primarily regulatory and does not serve the direct practical application of fitting lenses. Therefore, relying on the manufacturer's fitting guide is essential for effective and safe soft contact lens fitting.
