Orthokeratology contact lenses are rigid, gas-permeable lenses designed to reshape the cornea while worn overnight, offering a non-surgical alternative for correcting vision problems like nearsightedness. Clinically, they provide temporary refractive correction during the day by gradually flattening the cornea’s curvature through extended nighttime wear.
These lenses are reusable and made from materials that allow oxygen to reach the eye while resisting water absorption. Regulation varies by jurisdiction, but they typically require professional fitting and follow specific safety standards to ensure proper corneal health and vision outcomes.
