Which feature is crucial for fitting high myopia patients with contact lenses?

When fitting patients with high myopia, high riding capability of the contact lenses is a critical feature to consider. High myopia can often lead to deeper and larger corneas, which may result in a need for contact lenses that can effectively sit higher on the cornea without discomfort or instability. A lens that rides appropriately ensures that it remains centered and secured on the eye, reducing the risk of lens displacement, which could impair vision and comfort.

Additionally, a lens that fits well and allows for high riding capability will ensure adequate coverage of the corneal surface, crucial for patients with significant prescription needs. This fit is essential not only for visual acuity but also to promote ocular health.

While factors like lens thickness, base curve, and color tint are also important in the overall fitting process, they do not directly address the unique anatomical and visual requirements present in patients with high myopia as effectively as high riding capability does. Proper understanding and consideration of high riding capability can significantly enhance the fitting experience and overall satisfaction of high myopic patients with their contact lenses.
