Orthokeratology (ortho-K) lenses
Orthokeratology, also known as ortho-k, is a non-surgical procedure that uses specially designed contact lenses to temporarily reshape the cornea and improve vision. The lenses are typically worn overnight while sleeping, and they gently reshape the front surface of the eye. The goal of orthokeratology is to correct refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. It is also widely used for myopia management to slow down the progression of myopia.
.Here are some key points about orthokeratology:
- The procedure is often compared to dental braces, as it involves gradually changing the shape of the cornea, similar to how braces gradually straighten teeth
- Orthokeratology is reversible, meaning that the cornea will return to its original shape if the lenses are not worn regularly
- The vision improvements achieved through orthokeratology can be maintained as long as the lenses are worn as directed by the optometrist
- Orthokeratology is mainly used to correct myopia, but it can also be effective for lesser degrees of astigmatism and certain cases of hyperopia
- It is considered a noninvasive and nonsurgical alternative to procedures like LASIK or PRK, making it a potential option for individuals who are not suitable candidates for surgery
- Orthokeratology is commonly used in children, especially those with a family history of myopia or a significant increase in nearsightedness
- Numerous peer-reviewed studies have shown that orthokeratology is effective in slowing myopic progression in children. Ortho-k has been shown to slow myopic progression in children by 36-56% compared to their spectacle or contact-lens wearing peers.
- The optimal vision correction from orthokeratology may take a couple of weeks or longer to achieve, although some patients may experience significant improvement in just a few days
It is important to consult with your optometrist who specializes in orthokeratology to determine if this method is suitable for you or your child. Your doctor will conduct a thorough examination and provide guidance on the fitting, usage, and maintenance of the ortho-k lenses
Acuvue abiliti ortho-k contact lenses by Johnson & Johnson
Abiliti contact lenses are a type of orthokeratology lenses used for myopia management. Here is how they work according to the manufacturer:
- Abiliti Overnight lenses are orthokeratology contact lenses worn overnight to temporarily reshape the cornea, allowing clear vision during the day without correction. Each lens is specifically designed to fit each patient’s unique eye shape
- Abiliti Overnight lenses are designed to purposely flatten the shape of the cornea by applying slight pressure to the center of the cornea while the patient is asleep, resulting in a temporary reduction of myopic power
- Abiliti Overnight lenses are FDA-approved for myopia management in patients of all ages. They are designed to slow down the progression of myopia and reduce the risk of serious eye diseases associated with high myopia
- Abiliti Overnight lenses are considered safe and comfortable to wear. In three studies accounting for over 200 patient-years of wear, no serious adverse events or serious complications were found with Abiliti Overnight lens wear
- Abiliti Overnight lenses are fitted by eye care professionals who use a dedicated, intensive cleaner designed for gas permeable lenses weekly or bi-weekly, as recommended by the eyecare professional. The lenses are disinfected and stored in fresh, multipurpose solution compatible with gas permeable lenses for at least 4 hours. The lens case is rinsed daily with sterile rinsing solution and allowed to air-dry
In summary, Abiliti contact lenses are orthokeratology lenses worn overnight to temporarily reshape the cornea and reduce myopia progression. They are considered safe and effective for myopia management in patients of all ages. It is important to consult with your optometrist to determine if Abiliti lenses are suitable for you or your child.
Euclid ortho-K contact lenses
Euclid Ortho-K lenses are a type of orthokeratology lenses used for myopia management. Here are some key information according to the manufacturer:
- Euclid Ortho-K lenses are specifically designed for proactive myopia management in children. They are recognized as a world leader in orthokeratology lens designs, with over two million lenses on eyes
- Euclid Ortho-K lenses are a gentle, nonsurgical treatment that can lead to less dependence on glasses or contact lenses. They work by temporarily reshaping the cornea while the patient sleeps, allowing clear vision during the day without correction
- A recent U.S.-based, multi-site myopia management study demonstrated that orthokeratology, in general, and Euclid Vision’s Euclid Emerald Ortho-K lenses, in particular, are effective for myopia management. The study found that the use of Euclid Emerald lenses resulted in a statistically significant reduction in the progression of myopia compared to the control group
- Euclid Emerald Ortho-K lenses are approved for most patients with mild to moderate corneal astigmatism. It is important to consult with your optometrist to determine if Euclid Ortho-K lenses are suitable for you or your child.
In summary, Euclid Ortho-K lenses are a type of orthokeratology lenses used for myopia management in children. They are recognized as a world leader in orthokeratology lens designs and have been shown to be effective in reducing the progression of myopia. It is important to consult with your optometrist to determine if Euclid enses are suitable for you or your child
