History of Ortho-K
Ortho-K has been around longer than most people think

Orthokeratology (Ortho-K) has an interesting history that spans several decades. Here’s a brief overview:
Early Beginnings (1960s): The concept of reshaping the cornea using contact lenses originated in the 1960s. Dr. George W. Jessen, an optometrist, was among the first to explore the idea of using rigid gas-permeable lenses to alter corneal shape temporarily.
Refinement and Research (1970s-1980s): In the 1970s, further research and development led to improved lens designs. By the 1980s, Dr. Jessen's techniques gained traction, and the term "orthokeratology" began to be widely used.
Increased Popularity (1990s): The 1990s saw a surge in interest in Ortho-K, particularly for managing myopia in children. Studies began to demonstrate its effectiveness in vision correction and myopia control.
Technology Advancements (2000s): With advancements in technology, including corneal topography, custom lens designs became more precise. This period also saw the introduction of new materials, enhancing comfort and safety.
Regulatory Approvals (2000s-2010s): In various countries, including the U.S., regulatory bodies began approving specific Ortho-K lenses. This increased confidence among practitioners and patients.
Current Practices (2010s-Present): Ortho-K has become a well-established option for vision correction, particularly for children and teenagers. Ongoing research continues to explore its benefits for myopia control and long-term safety.
Today, Ortho-K is recognized as a safe and effective method for managing refractive errors, with an emphasis on personalized care and regular monitoring. Its popularity continues to grow, especially among parents seeking alternatives to traditional glasses or daytime contact lenses for their children.
