Orthokeratology Lens Market Size

Orthokeratology Lens Market Growth Projections and Opportunities

Orthokeratology is a way to treat eye problems without surgery. It uses special rigid gas permeable contact lenses to help with issues like nearsightedness (myopia), farsightedness (hypermetropia), and astigmatism. These lenses are made from different materials, chosen based on factors like oxygen permeability, moisture content, specific gravity, and stability.

The global orthokeratology lens market has different types of materials used for these lenses. One type is silicone acrylate, which was the first material used for making these lenses. It has advantages like high gas permeability, better thermal conduction, and less warping compared to other materials.

Another material is fluorosilicone acrylate, which combines silicone acrylate with fluorinated monomers. This improves the moisture content of the material and enhances oxygen transmission. This material is chosen because it provides better visibility and reduces the siloxane component.

Fluorocarbon acrylate is made of methyl methacrylate and fluorine, with n-vinyl pyrrolidone added for moisture. It offers high oxygen permeability, more moisture, and resistance to proteins, making it flexible.

There are other materials like oprifocon acrylate and different forms of fluorosilicone acrylate used to make these lenses. The choice of material depends on factors like optical quality and stability.

The use of orthokeratology lenses is based on different eye conditions. Myopia, or nearsightedness, is when things up close are clear, but things far away are blurry. Around 40% of the US population has myopia, and this number is expected to grow. By 2050, it's predicted that 50% of the world's population, almost 5 billion people, will have myopia.

Hyperopia, or farsightedness, is another common condition where distant objects are seen more clearly than close ones. The prevalence of hyperopia increases with age, and it's a driving factor for the orthokeratology lens market as these lenses are needed to treat various eye disorders.

In summary, orthokeratology is a non-surgical solution for eye problems, using different materials for lenses. These materials are chosen based on their properties. The lenses are used to address conditions like myopia and hyperopia, which are widespread vision issues affecting a significant portion of the global population.
