The history of ortho-k
Orthokeratology, commonly known as Ortho-K, has provides a unique and revolutionary option in the world of vision correction. This non-surgical method offers an alternative for those seeking freedom from glasses and contact lenses. To truly appreciate its significance, let's embark on a journey through the captivating history of Ortho-K.
Early Discoveries: The concept of corneal reshaping can be traced back to the early 1960s when researchers explored the effects of rigid contact lenses on the cornea's curvature. Dr. George Jessen specially designed lenses to flatten the front surface of the cornea to temporarily correct for nearsightedness. Dr. Kerns published research in the 1970s that concluded that ortho-k was unpredictable and uncontrollable. Dr. Polse published research in the 1980s with similar conclusions that the quality of vision was difficult to predict.
Advancements in Technology: Orthokeratology began gaining momentum in the 1990s with the development of newer technology. Advancements in highly oxygen permeable lens materials, ortho-k lens designs, and technology to map the shape of the eye refined the effectiveness and comfort of the treatment.
FDA Approval and Mainstream Success: In 2002, ortho-k gained recognition when the U.S. Food and Drug Administration (FDA) approved Paragon Vision Sciences for overnight wear for the temporary reduction in myopic refractive error . This approval solidified ortho-k's legitimacy and sparked widespread interest among eye care professionals and patients alike.
Continued Research and Refinement: Since then, ortho-k has been subject to extensive research, leading to significant advancements in lens design, manufacturing techniques, and treatment protocols. Studies have demonstrated its efficacy in managing myopia progression in school-aged children.
Global Impact and Future Prospects: Ortho-k has garnered global attention as a viable solution to correct for nearsightedness and offer clear vision, with the potential to slow down progression in children. The ongoing research and development in this field hold promising prospects for further improvements and expansion of ortho-k candidates.
The journey of ortho-k has been one of innovation, research, and transformation. From early discoveries to FDA approval and ongoing advancements, ortho-k has emerged as a game-changer in vision correction. With its ability to provide temporary corneal reshaping and clear daytime vision, ortho-k continues to evolve, offering new hope for those seeking visual freedom.
