  • CONTACT LENS
    Publication number: 20240118562
    Abstract: A contact lens for shaping a cornea of an eye of a patient to treat high cylinder astigmatism may include a peripheral portion, an alignment portion, a treatment portion, a reverse portion, and a staining feature. The peripheral portion may cause migration of epithelial cells from a periphery of a cornea of the eye of the patient towards a center of the cornea of the eye of the patient. The alignment portion may align the contact lens on the cornea. The treatment portion may cause migration of the epithelial cells from the center of the cornea towards the periphery of the cornea. The reverse portion may relieve pressure caused by the migration of the epithelial cells. The staining feature may contact the cornea, thereby reshaping the cornea to treat high cylinder astigmatism. The staining feature may apply a ribbon-shaped staining pattern to the cornea across the contact lens.
