The OCUVIQ™ dk-4 is a flagship-tier overnight Orthokeratology (Ortho-K) lens. Compared to the dk-3 series, the dk-4 utilizes a patented material with an even higher oxygen permeability (Dk) value, elevating corneal safety during sleep to a superior dimension while maintaining precise reshaping. By physically reshaping the cornea overnight, it grants wearers clear unaided vision throughout the day—a premium choice for youth myopia control and adults seeking visual freedom.
Core Technology & Benefits
dk-4 Flagship Oxygen Permeability: The dk-4 represents the highest material oxygen permeability in the series. In the extreme hypoxic environment of closed-eye sleep, it provides an oxygen supply close to that of the naked eye, safeguarding the metabolic health of corneal epithelial cells and minimizing redness or edema.
High-Precision Reverse Geometry: The lens design is more refined, guiding central corneal fluid dynamics more gently and accurately for rapid reshaping. Its stable alignment zone ensures the lens remains perfectly centered, even if the wearer moves during sleep.
Enhanced Myopia Control: Utilizing the principle of peripheral defocus, the dk-4 effectively inhibits axial elongation. For children and adolescents with rapidly progressing myopia, this model offers a more robust and steady control performance.
Moisture Enhancement Surface: The lens surface undergoes advanced hydrophilic treatment, allowing it to attract tears and form a protective film. This improves initial comfort and prevents the lens from sticking too tightly to the cornea, making morning removal smoother.
