Orthokeratology is specialized area of optometry where patient will sleep in a reverse geometry hard contact lens. This Ortho K lenses will reshape the cornea overnight so patients don’t need any correction to be worn during the day. There is also evidence that suggests that Ortho K lenses slows progression of short sightedness or myopia in young eyes. Our optometrists will assess patients best suited for this revolutionary treatment. Patients with orthok lenses will be reviewed couple of times a year to best monitor their treatment and visual outcomes.
Optometrists can successfully treat short sightedness or myopia up to -8.00, long sightedness or hyperopia up to +4.00 and astigmatism up to -3.00 for best visual outcomes. We will map your cornea carefully with a corneal topographer which will give us very precise details to make you a pair of orthok lenses. We will also use the corneal topographer to monitor change on your cornea during the treatment process.
Reverse geometry RGP lenses will flatten the cornea on intended areas to temporarily reshape it. This will happen overnight while you are wearing the lenses. So you will only need a good night sleep for them to work. When you wake up in the morning and take your lenses out you will see your day clearly. It is easy and simple as that.
Most patients will see a difference in their vision even after the first night of wearing the lenses. You will see and significant difference after the 1st week of wear and treatment will really take hold after the 1st month of wear. We will assess your eye at every step to make sure everything is progressing as expected.
With appropriate care these lenses can last anywhere from 12 to 24 months. It is recommended that you change the lenses as directed by the optometrist to ensure safety and efficacy of the treatment.
Potential side effects of orthok lenses are no different to traditional contact lens wear. These can include mild irritation and redness. There is also a small risk of infection which usually only arise due to poor hygiene in most cases. Our optometrists are well informed on handing these issues if you were to arise.
OrthoK is a completely reversible non-invasive procedure to correct the refractive error, hence once the treatment is ceased then refractive error will regress back to what it was originally. So once stopped patients can go back to wearing their glasses or traditional contact lenses for visual correction.
The cost of the lenses can depend on the complication and work that goes into making sure they work. OrthoK lenses can approximately cost about $450 per lens. The consultation fees involved in fitting these lenses are usually about $100 per appointment. All new wearers will need atleast 5 appointments over a 6 month period. If you are interested we ask that you make an appointment to see one of our optometrists to see if you are a candidate for orthok
