There is a lot of talk in the media about Ortho-k lenses and we find increased interest from parents and schools for information about this amazing way to correct vision overnight.
- What is Ortho-k?
Ortho-k is the fitting of specially designed contact lenses that you wear overnight. While you are asleep, the lenses gently reshape the front surface of your eye so you can see clearly the following day after you remove the lenses when you wake up.
Studies show that Ortho-K slows the progression of myopia in children
- How long does the effect last?
You should be able to see acceptably well without glasses or contact lenses for a day or two, sometimes longer. For best results, you should wear the Ortho-k lenses every night.
- Which vision problems can Ortho-k correct?
Ortho-k lenses are prescribed for two purposes: (1) To correct eyesight – mainly short-sightedness but also some cases of astigmatism and presbyopia and (2) To slow the progression of childhood myopia.
- Who is a good candidate for Ortho-k lenses?
Athletes and people who don’t like wearing spectacles are great candidates but most people with mild to moderate short-sightedness (myopia) are good candidates for Ortho-k. The effect is temporary and there is very little risk involved. You can also discontinue wearing the lenses and your eyesight will revert to its original state.
Laser vision correction surgery is not a good idea for children as their condition needs to stabilise before the surgery is performed, hence the ortho-k lenses as a great alternative.
The greatest benefit however is to school aged children because of the ability to slow the progression of short-sightedness.
- Who fits Ortho-k lenses?
It is important to know that the fitting of Ortho-k lenses is a very specialised type of contact lens fitting, and not all optometrists who fit contact lenses also fit ortho-k lenses. At Classic Eyes both our Bournemouth and Poole practices offer Ortho-k lenses and we have many successful and happy patients currently using these lenses.
- What can you expect from Ortho-k?
We usually aim for 20/ 20 vision after Ortho-k.
- What to expect when you begin Ortho-k.
Our optometrist will do a full eye examination including taking a few extra measurements needed for fitting the Ortho-k lenses. This measurement is very important and gives the optometrist a topographical map of the front surface of your eyes.
The optometrist will then order custom Ortho-k lenses for fitting at a later date.
You may need a series of temporary lenses to see properly until you reach the desired prescription. In most cases, up to three pairs of lenses are required to achieve the maximum vision correction effect.
When you begin to wear Ortho-k lenses, you will likely have some awareness of the lenses on your eyes until you fall asleep. With time, the lenses typically become more comfortable immediately upon insertion.
- How long does it take for the maximum Ortho-k effect?
This varies and depends on the severity of your condition, especially the amount of short-sightedness (and possibly astigmatism) you have when you begin the ortho-k process.
Some people can have excellent vision after a day or two of overnight ortho-k. But for higher prescriptions it can take two weeks or longer for maximum correction.
Until your eyes are fully corrected, you might notice blurred vision and glare and halos around lights. In some cases, you may need to wear glasses (with a lesser prescription than you originally had) during the Ortho-k process. Also, in some cases, mild glare and halos might persist even after maximum Ortho-k correction.
- How Much Does Ortho-k Cost?
Fitting Ortho-k lenses is a more time-consuming process and requires more expertise than fitting regular contact lenses. It requires a series of office visits and potentially multiple sets of lenses so we offer a direct debit scheme to all Ortho-k patients. Our optometrist will discuss all options available during your initial consultation.
10.Can I have laser vision correction surgery after Ortho-k?
Yes, it’s possible to have laser surgery after Ortho-k if you later desire vision surgery to permanently correct your eyesight.
Unlike laser vison correction, Ortho-k is reversible. If you try reshaping lenses and later decide you want laser eye surgery instead, you can do that.
But you will have to discontinue wearing the lenses and wait a period of time before surgery (possibly several months) to allow your corneas to fully revert to their pre-Ortho-k shape.
Finally, keep in mind that, as with all contact lenses, there are some possible side effects and complications of wearing Ortho-k lenses.
