Orthokeratology
Ortho K Lenses
What is Orthokeratology ?
Orthokeratology (Ortho-K)
is a non-surgical procedure that uses specially designed contact lenses to reshape the curvature of your cornea while you sleep. It can help prevent myopia from worsening. The next day, you can see clearly without your spectacles once you remove your Ortho-K lenses.
No Glasses. No Daytime Contact Lenses. No Surgery
The Aim of Orthokeratology
The goal of Ortho-K is to correct nearsightedness and astigmatism, allowing you to achieve clear vision without relying on spectacles or contact lenses. Additionally, it aims to slow down the progression of myopia.
Ortho-K contact lenses go beyond refractive correction by eliminating the need for spectacles or daily contact lens wear. Its main advantage lies in its ability to control myopia progression.
Risks of Untreated Myopia
Myopia, commonly known as nearsightedness, is a prevalent vision condition affecting millions worldwide. While it may seem harmless, untreated myopia can pose significant risks to eye health and overall well-being.
Benefits of Myopia Control
1. Vision Preservation:
Ortho K lenses slow myopia progression by reshaping the cornea overnight. This proactive approach helps preserve visual acuity and reduces the risk of developing high myopia and related eye conditions.
2. Optimal Eye Health:
Ortho K lenses lower the risk of eye diseases like retinal detachment and glaucoma by minimizing eyeball elongation. Early adoption of Ortho K lenses promotes long-term ocular wellness.
3. Enhanced Daily Functioning:
Users enjoy improved visual comfort and clarity throughout the day. Reduced dependence on corrective eyewear enhances productivity and confidence.
4. Customized Treatment:
Ortho K lenses offer personalized myopia management tailored to individual needs. Custom treatment plans ensure optimal vision correction and long-term myopia control.
Who is Suitable for Ortho-K Lenses?
For adults who rely on soft contact lenses, Ortho-K also offers a solution for managing dry eye condition. Since these lenses are only worn during sleep and removed the next day, they can help alleviate discomfort caused by long hours of soft contact lens wear.
Ortho-K lenses are suitable for adults or kids engaged in sports activities, as they offer clear vision without the hassle of glasses or traditional contact lenses.
Not only for adults, Ortho-K lenses are particularly effective for individuals with mild to moderate myopia (refractive correction less than 7.00 diopters) and astigmatism (less than 2.50 diopters).
Ortho-K contact lens provide an alternative to LASIK surgery for those who are not eligible for the procedure or prefer not to undergo surgery. They offer the convenience of clear vision without the need for glasses or contact lenses throughout the day.
How does Ortho-k Lenses work ?
Ortho-k contact lens is actually a rigid gas permeable lens which is specially designed into a special curve that helps to gently create a water pressure that forms within the cornea surface when it is worn. The pressure will flatten the front surface of the cornea and that will help to refocus lights entering your eye properly. Hence, vision will be clear after removing the ortho-k lenses.
Step 1
Before
The patient wears a special contact lens while sleeping at night.
Step 2
During
This ortho-k contact lens is designed in such a way that it will use the tears of the patient to gently reshape the cornea while the patient is sleeping.
Step 3
After
When the patient wakes up in the morning, he/she will remove the ortho-k contact lens and enjoy clear vision for the rest of the day.
Is it safe ?
Ortho-k lenses are made from materials that FDA approves. It is similar to a contact lens , and it potentially carries the risk of contamination and causes infections.However the risk is very minimal if individuals follow proper cleaning regime, handling of the lenses and regular visits to optometrist.
Compared to Lasik, Orthokeratology offers a simpler and safer method to correct one’s vision.
How fast will I see results ?
The process treatment varies from case, individuals with higher level of refractive error may find themself needing more time (weeks to a month) in treatment to achieve best vision compared to lower refractive errors may sometimes see significant changes over the 1st night of wearing.
For the first 3 months of treatment, optometrist will schedule follow up sessions according to the progress of results and stability of lens fitting.
Once optimum vision is achieved with customized ortho-k lenses, you may continue with the regular ortho-k routine until your next replacement schedule.
Are Ortho K lenses suitable for children?
Yes, Ortho K lenses not only for adults, but are often recommended for children from 5 years old above with myopia. They can help slow down the progression of myopia in children and may be especially beneficial for those who are too young for other vision correction methods like LASIK.
What is the Ortho K lenses price?
The price of Ortho K lenses varies based on factors like brand, prescription complexity, and location. It’s best to consult an eye care professional for specific pricing details.
Are Ortho K and contact lenses the same?
For new wearers, ortho-k is typically less comfortable than soft contact lenses, but comfort usually improves dramatically within the first week.
Ortho K lenses are a type of contact lens, but they are used differently from traditional contact lenses. While traditional contact lenses are worn during the day and removed at night, Ortho K lenses are worn overnight to reshape the cornea, providing clear vision during the day without the need for glasses or contacts.
Are Ortho-K lenses worn monthly like traditional contact lenses?
No, Ortho-K contact lens is not worn monthly. They are worn overnight while sleeping and replaced every 1-2 years, depending on the individual’s needs and the recommendation of their eye care professional.
Orthokeratology in short is called ortho-K
Ortho-k lenses are worn during sleep to gently reshape the cornea so you can see clearly during the day without the need for glasses or contact lenses.
Correction from ortho-k is reversible and requires ongoing overnight wear to prolong its stability.
For new wearers, ortho-k is typically less comfortable than soft contact lenses, but comfort usually improves dramatically within the first week.
Ortho-k is safe to wear as long as lens wear and care guidelines are followed, and ongoing follow-up care visits are attended.
Provides a great alternative to kids or adults who are active in lifestyle.
Those who may fail to undergo LASIK surgery.
Those who are not suitable for long days of soft contact lens due to dry eye condition.
When it comes to slowing down myopia progression, Orthok have shown to have the ability to to slow it down by about half.
