Orthokeratology & Myopia Control
in Chennai

Myopia in children does not just blur vision — it progresses every year, increasing the risk of serious eye disease in later life. Ortho-K overnight lenses and low-dose atropine are clinically proven to slow that progression.

Why Controlling Myopia Progression Is Critical

Many parents believe myopia is simply a matter of stronger glasses each year. In fact, progressive myopia increases the risk of retinal detachment, glaucoma, macular degeneration, and cataracts — conditions that can cause permanent vision loss in adulthood.

Myopia Control Options We Offer in Chennai

The best myopia control strategy depends on your child's age, degree of myopia, and lifestyle. We offer all evidence-based options and help you choose the right approach.

Orthokeratology (Ortho-K) Overnight Lenses

Gas-permeable lenses worn only at night gently reshape the cornea, providing clear daytime vision without glasses or contact lenses. Simultaneously proven to slow axial elongation — the primary driver of myopia progression.

Low-Dose Atropine Eye Drops (0.01%)

Nightly atropine drops at 0.01% concentration slow myopia progression by an average of 50–60% with minimal pupil dilation or near-vision blur — the key advantage over higher concentrations.

Multifocal Soft Contact Lenses

Specially designed contact lenses with peripheral defocus zones that reduce the signal driving axial growth. A good option for children who want daytime contact lens wear.

Myopia Control Spectacle Lenses

Defocus incorporated multiple segments (DIMS) and highly aspherical lenslet (HAL) spectacle designs show meaningful myopia control in children who prefer glasses.

Axial Length Monitoring

We measure axial length every 6 months using biometry to objectively track whether progression is being controlled — going beyond subjective prescription changes alone.

Getting Started with Ortho-K in Chennai

01

Comprehensive Myopia Assessment

We measure corneal topography, axial length, pupil size, and refraction to determine whether Ortho-K is suitable and to design the correct lens parameters.

02

Custom Lens Design and Fitting

Each Ortho-K lens is individually designed using your corneal topography map. We trial fit in-clinic and verify the fit before dispensing.

03

First Night and Morning Review

After the first overnight wear, you return the next morning so we can assess the corneal reshaping pattern and adjust the prescription if needed.

04

1-Week and 1-Month Follow-Ups

We monitor corneal topography changes and visual acuity at 1 week and 1 month to confirm optimal reshaping and comfort.

05

6-Monthly Axial Length Checks

Axial length measurement every 6 months confirms whether progression is being controlled. We adjust the myopia management strategy based on objective data.

Who Is a Good Candidate for Ortho-K?

Ortho-K is most effective for children aged 7–18 with myopia between -0.75D and -6.00D and minimal astigmatism. It is particularly well-suited for active children involved in sports who dislike daytime glasses or contact lenses. Adults seeking freedom from daytime correction may also benefit — though myopia control effects are primarily relevant in children whose eyes are still growing.

Orthokeratology FAQs

Is it safe for children to sleep in contact lenses?
Ortho-K lenses are made from highly oxygen-permeable gas-permeable materials specifically approved for overnight wear. With proper fitting, hygiene, and regular follow-up, they are safe. The risk of infection with Ortho-K is comparable to daily soft contact lens wear.
How long until my child can see clearly without glasses during the day?
Most children achieve functional daytime vision within 1–2 weeks. Full correction usually stabilises within 4–6 weeks, depending on the degree of myopia.
What if my child stops wearing Ortho-K?
Orthokeratology is fully reversible. If your child stops wearing the lenses, the cornea returns to its original shape within a few days to weeks. The myopia control benefit also ceases, so consistency is important during the growing years.
Can atropine and Ortho-K be combined?
Yes. Combining low-dose atropine with Ortho-K is used in cases of rapidly progressing myopia and has shown additive myopia control effects in several studies. We will recommend combination therapy when indicated.
