  1. Best Answer

    A common complication with corneal GP lenses is 3 and 9 o’clock staining, which is a result of epithelial punctate staining of the peripheral cornea near the edge of the GP lens. These so-called 3 and 9 o’clock areas may not be adequately resurfaced with tears after a blink, thus resulting in small desiccated regions.
