Rigid Gas Permeable Contact Lenses

Fiona Watt Optometrists proivde Orthokeratology, or Ortho-K in Wimbledon. Ortho-K is a lens fitting procedure that uses specially designed rigid gas permeable (RGP) contact lenses to change the curvature of the cornea to temporarily improve the eye’s ability to focus on objects. This procedure is primarily used for the correction of myopia (short sightedness).
Ortho-K lenses are worn overnight, prescribed to be worn while sleeping for at least eight hours each night. They are removed upon awakening and not worn during the day. Some people can go all day without their glasses or contact lenses. Others will find that their vision correction will wear off during the day. Ortho K is completely reversible with 99% normality restored within 5 days of stopping lens wear.

How does EyeDream work?
The cornea plays a key role in creating a sharp optical focus. EyeDream lenses gently reshape the curvature of the cornea overnight, creating a slightly flatter profile.
Upon waking, the slight change (less than half the width of a human hair) in cornea curvature is enough to create clear, sharp vision for the duration of the day.
Journey To A Clearer Future
Eye Dream for children
Research has demonstrated that Orho-K lenses have a great benefit in helping to slow progression of myopia by reducing the amount of blur on the peripheral retina. Short sightedness has a tendency to get worse as children grow, especially where there is a strong family connection. Wearing Ortho -K lenses can slow this progression by up to 50%. The results vary for each individual child, but most experts maintain that these lenses are the best option available for children suffering from myopia.
EyeDream offers children and parents many benefits, including:
Myopia control
Ortho-k lenses such as EyeDream, offer the children and parents the best opportunity to reduce or halt the progression of myopia.
Active lifestyle
EyeDream offers children the freedom and confidence to swim, play sports and enjoy an active lifestyle without the restrictions of specs or contact lenses.
Peace of mind
EyeDream lenses are worn at night and at home so lens wear & care can be monitored – And, no more lost spectacles.

At your initial examination, the optometrist will go through the Ortho –K treatment programme in detail and answer any questions or concerns you have. An eye examination will be carried out and the curvature of your cornea will be measured using our corneal topographer. This will give us the most accurate measurements required to make your bespoke contact lenses to achieve the best treatment, fit and vision.
Several pairs of custom made lenses may be fitted initially to find the one that gives the best fit and optimal vision. You will be required to come and see the optometrists on the mornings of the first, third day after wearing the lenses overnight. Theses checks are repeated at 1 week, 1 month, 3 months and 6 months and thereafter every six months. At the six months check-ups, you will also be required to have an annual eye examination and your Ortho-K lenses will be replaced.
Yes, once the effect is complete you simply remove the lenses each morning and you can see normally throughout that day.
After the first night most of the necessary correction has been achieved. Normally, within a week, your sight during the day will be ‘treated’ and you will no longer be reliant on glasses or contact lenses.
EyeDream lenses are made of one of the very highest oxygen permeable materials, Boston XO™, for maximum comfort and safety during overnight wear.
Yes. Research and experience show that the whole process is 100% reversible. So if you decide to stop wearing EyeDream the eye will return to its original shape. This makes EyeDream an excellent alternative to laser eye surgery.
Simply book an appointment with our optometrist by calling the practice on 0208 944 6886. If you are suitable your eyes will be analysed on an eye-mapping instrument and from the data gathered, lenses are ordered.
