Orthokeratology (Ortho-K): A Clear Alternative to Glasses and Surgery
At Rose Optometry in Berry, we’re pleased to offer Orthokeratology (Ortho-K) — a safe, effective, and non-surgical way to correct short-sightedness without glasses, daytime contact lenses, or laser surgery.
What is Ortho-K?
Orthokeratology, also known as Ortho-K, OK lenses, or corneal reshaping therapy, uses specially designed rigid gas permeable (RGP) contact lenses worn overnight while you sleep.
As you rest, the lenses gently reshape the front surface of your eye (the cornea). In the morning, you simply remove the lenses and enjoy clear vision throughout the day — with no glasses or contact lenses required.
Unlike laser eye surgery, the effects of Ortho-K are completely reversible. If you stop wearing the lenses, your eyes will gradually return to their natural shape.
Who Can Benefit from Ortho-K?
Ortho-K is most commonly used to correct short-sightedness (myopia), with or without low levels of astigmatism. It can be an excellent option for:
Children with progressing myopia
Active adults involved in sport or outdoor activities
People who experience dryness or discomfort with soft contact lenses
Those seeking an alternative to laser eye surgery
Benefits of Orthokeratology
Helps slow myopia progression in children — research shows Ortho-K can significantly reduce the progression of short-sightedness.
Freedom during the day — no glasses or contact lenses needed for school, work, or sport.
Ideal for active lifestyles — especially helpful for swimming, team sports, and outdoor activities.
Comfortable for dry eye or allergy sufferers who may struggle with daytime contact lens wear.
A non-surgical, reversible alternative to laser vision correction.
Customisable over time as your vision or prescription changes.
Is Ortho-K Safe?
Like all contact lens wear, Ortho-K carries some risks, including infection if lenses are not cleaned and worn correctly. However, with proper hygiene, regular follow-up, and professional supervision, Orthokeratology is considered a safe and well-established treatment.
Some people may notice mild glare or halos during the initial adaptation period, particularly at night. These symptoms usually improve as your eyes adjust.
To keep your eyes healthy, it is important to:
Follow all cleaning and hygiene instructions carefully
Replace your lenses as recommended (typically every 12 to 18 months)
Attend all scheduled follow-up appointments
The Ortho-K Process at Rose Optometry
1. Initial Consultation
We assess your prescription, eye health, lifestyle, and suitability for treatment.
2. Corneal Mapping
A painless and highly detailed scan maps the unique shape of your cornea.
3. Custom Lens Design and Fitting
Your lenses are individually designed for your eyes and prescription.
4. First Night of Wear
Most patients notice significantly clearer vision after just one night.
5. Ongoing Monitoring
Regular reviews allow us to fine-tune the fit and monitor your eye health.
Follow-Up Schedule
To ensure the best visual outcome and long-term eye health, follow-up appointments are typically scheduled:
After the first night of wear
At one week
At one month
At three months
Every six months thereafter
Long-Term Care
Replace lenses approximately every 12 to 18 months, depending on their condition
Attend regular six-monthly reviews
If you stop wearing Ortho-K lenses, your eyes will gradually return to their natural shape
Why Consider Ortho-K for Children?
Myopia is becoming increasingly common in children. Higher levels of myopia are associated with an increased risk of retinal detachment, glaucoma, and myopic macular degeneration later in life.
Orthokeratology is one of the most effective evidence-based options available to help slow myopia progression during childhood.
