Paragon ortho-k lenses are designed for individuals with myopia ranging from -1.00 D to -6.00 D, with refractive astigmatism of up to -1.75 D.
Today’s ortho-k lens material allows excellent transmission of oxygen to the cornea, greatly improving the safety of ortho-k treatment. Complications with ortho-k lenses can be minimised with strict adherence to appropriate wearing and a cleaning regime.
Persons who demonstrate some or any of following symptoms in the eye:
To find out whether you are a suitable candidate for ortho-k treatment, a comprehensive eye examination is warranted. This includes a full refractive evaluation, an ocular health exam and a corneal shape workup. If the patient is suitable, then OK lenses will be either fitted or ordered based on the measurement obtained.
Choosing a right ortho-k lens candidate is the first step toward a successful treatment, patients will be re-assessed at regular intervals: •one day •one to two weeks • three months • six months. After the first six months follow up without any problems, patients will be seen annually for a full eye examination, which includes assessment of ortho-k lens condition & its effectiveness and corneal health.
Cleaning procedure includes the following steps: cleaning, disinfection and storage of the lens. Although the cleaning principle is the same for different kinds of lenses, ortho-k lens requires slightly different cleaning regime. An additional regular protein removal process is usually necessary to keep ortho-k lenses clean in order to maintain its efficacy. Please follow Ortho-k Lens Cleaning instructions carefully.
Although patients can see clearly while wearing ortho-k lenses, it is not recommended during early treatment period. Patients often experience some discomfort or irritation upon insertion. This discomfort may lead to excessive blinking which can cause lens mispositioning. The discomfort often dissipates after the first 2 weeks.
No, there is no need to remove the ortho-k lenses if awoken during the night.
Whilst removal is usually easy, it is advisable that patients instil a few rewetting drops before removing the ortho-k lens. In some cases, patients prefer to use DMV remover.
Vision improves rapidly after a couple of hours of wearing. Most patients achieve stable day time vision within 2 weeks of nightly wear.
In addition to vision correction, the prevention of myopia progression is the biggest advantage of orthokeratology. Secondly, clear unobstructed vision allows patients to participate in sports activities comfortably.
Although the principle of correction is the same, the chief advantage of ortho-k is that it allows patients with myopia to avoid surgery for obtaining good uncorrected visual acuity during the day. Moreover Ortho-k is very effective for juvenile myopia control.
Although most patients are required to wear the lenses every night in order to maintain the appropriate corneal shape, some can wear Ortho-k lenses less frequently.
The lens can last up to two, even three years if patients take care of lenses by strictly following the cleaning regime as advised by your consultant.
Most optical insurance plans will cover some contact lens costs. The best way to find out the details of your specific plan is to call your insurance company.
