When a soft contact lens demonstrates excessive movement, what should be considered?

When a soft contact lens demonstrates excessive movement, it indicates a poor fit, which can cause discomfort, reduce visual acuity, and lead to complications. In such situations, one appropriate solution is to consider choosing a larger diameter lens. A larger diameter lens has a greater coverage area, which can help it better conform to the natural shape of the eye. This increased coverage can minimize excessive movement, resulting in improved stability and a more comfortable fit.

Taking into account other resizing or fit adjustments—like selecting a smaller diameter lens or changing the base curve to a steeper fit—instead would not appropriately address the issue if the excessive movement is significant. Additionally, while switching to a soft toric lens may be necessary for astigmatic correction, it does not directly address the excessive lens movement concern and would not be the primary recommendation in this context.
