    Orthokeratology<\/strong> (noun; also ortho-k, OK, corneal reshaping)<\/em>: orthokeratology is the use of specially designed rigid gas-permeable contact lenses, usually worn overnight, to temporarily flatten the front of the cornea so that short-sightedness (myopia) is corrected during the day without glasses or lenses. The effect is reversible: if the lenses are stopped, the cornea returns to its original shape.<\/p>\n\t\t\t

    Ortho-k lenses UK cost, in short:<\/strong> ortho-k is a private service in the UK. Opticians set their own fees, the NHS does not pay for it, and the price is typically quoted as a fitting-and-lenses package plus aftercare.

    Ortho-k lenses UK cost: what will you pay?<\/h2>\n\t\t\t\t

    The honest answer is that there is no single UK price.<\/strong> Orthokeratology is not offered on the NHS, so every practice sets its own fees, and they vary with the practice, the lens design, how complex your eyes are and how many aftercare visits are included. The UK range is {{UK ortho-k price range}}<\/span> (checked {{price check date}}<\/span>). We do not quote a UK figure here that we have not been able to source.<\/p>\n

    What we can source is a benchmark from the United States. The American Academy of Ophthalmology (AAO) says the initial cost of ortho-k runs from US$1,000 to US$4,000 depending on the type and degree of refractive error, with US$300\u2013$500 a year afterwards for replacement lenses, solutions and check-ups. Because ortho-k is elective, insurance rarely pays for it.<\/p>\n

    When you compare quotes, ask each practice exactly what the price covers:<\/p>

    Is ortho-k available on the NHS?<\/h3>\n

    No. The NHS says myopia-management options for children, which include overnight orthokeratology lenses, are not available on the NHS because more research is needed. The College of Optometrists’ patient website says the same: none of the myopia-management treatments is currently funded by the NHS in any part of the UK, and they cost more than ordinary glasses or contact lenses. Whether you are an adult wanting daytime freedom from glasses or a parent considering it for a child, the ortho-k lenses UK cost is a private expense.<\/p><\/div>\t<\/div><\/div><\/div><\/section>\n\n\n\n\n

    How does orthokeratology work?<\/h2><\/div>

    Ortho-k works by gently moulding the cornea while you sleep.<\/strong> The cornea is the clear front window of the eye and provides most of its focusing power, so even a very small change in its curve changes your prescription. In short-sightedness, the cornea is too steep or the eye is too long, so light focuses in front of the retina.<\/p><\/div><\/div>\t\t

      \n\t\t\t\t
    1. \n\t\t\t\t\t\t

      Mapping<\/h3>\n\t\t\t\t\t\t

      Your fitter scans the surface of your cornea (corneal topography) and measures your prescription.<\/p>\n\t\t<\/div><\/li>\n\t\t\t\t

    2. \n\t\t\t\t\t\t

      Custom lenses<\/h3>\n\t\t\t\t\t\t

      The lenses are designed from that map. They are rigid and gas-permeable, shaped to flatten the centre of the cornea.<\/p>\n\t\t<\/div><\/li>\n\t\t\t\t

    3. \n\t\t\t\t\t\t

      Overnight wear<\/h3>\n\t\t\t\t\t\t

      You wear the lenses while you sleep. The FDA says overnight ortho-k lenses are the most common type and are usually worn for at least eight hours a night.<\/p>\n\t\t<\/div><\/li>\n\t\t\t\t

    4. \n\t\t\t\t\t\t

      Daytime vision<\/h3>\n\t\t\t\t\t\t

      On waking you remove the lenses. The central cornea stays flatter for a while, so distance light focuses on the retina and you can see without glasses.<\/p>\n\t\t<\/div><\/li>\n\t\t\t\t

    5. \n\t\t\t\t\t\t

      Maintenance<\/h3>\n\t\t\t\t\t\t

      The effect fades, so the lenses must be worn every night or on another schedule your fitter prescribes. If you stop, the cornea returns to its original shape and the short-sightedness returns.<\/p>\n\t\t<\/div><\/li>\n\t\t\t<\/ol>\n\t\t

      Adjustment takes a little time. Some people see well after one or two nights, but with higher prescriptions it can take two weeks or longer for the full effect, and blur or halos can occur while the cornea settles.<\/p><\/div><\/div><\/div><\/div><\/section>\n\n\n\n\n

      Who is ortho-k suitable for?<\/h2>\n\t\t\t\t\t\t

      Ortho-k suits people with low to moderate short-sightedness who want clear daytime vision without glasses and without irreversible surgery.<\/strong> It is most often used for:<\/p>\n\t\t\t\t\t\t
