Poor GP insertion or recentering techniques may result in which of the following?

The best choice here is arcuate staining. This condition refers to the staining pattern on the cornea that can occur when a rigid gas permeable (GP) lens is improperly positioned on the eye. When the lens is not correctly centered or inserted, the edge of the lens may create points of pressure on the cornea. This can lead to staining along the areas where the lens interacts with the corneal epithelium, creating an arcuate pattern.

When a GP lens is not fitting well or is off-center, it can cause uneven pressure distribution, resulting in areas of hypoxia or dryness, which contribute to this type of staining. Proper insertion and recentering techniques are essential to avoid such issues, as they help ensure that the lens maintains contact with the cornea uniformly across the entire surface.

Understanding the mechanics of GP lens fitting is crucial for contact lens practitioners, as it directly impacts patient comfort and health. Recognition of signs such as arcuate staining is vital for timely intervention and adjustment of the fitting to promote better visual health outcomes.
