Orthokeratology
Overnight lenses temporarily reshape the cornea to improve daytime vision. Learn about suitability for children and adults, myopia management, safety and the ongoing care these lenses require.
Orthokeratology lenses are worn while you sleep. They gently reshape the cornea overnight, and you remove them in the morning. For the day, the idea is vision without glasses or daytime contacts.
It is a non-surgical approach and, because the effect is temporary, it is reversible: stop wearing the lenses and the cornea gradually drifts back.
The same technology serves two very different goals. For adults the usual aim is temporary correction of nearsightedness. For children the conversation is often about managing myopia, which is a separate matter explained below.

Evolutionary Eye Care reports clinical observations of up to 80–95% slowing of myopia progression. This practice-reported figure is not a guaranteed outcome. Individual results vary; assessment and ongoing monitoring are required.
Ortho-K is not one program. The reasons for choosing it, and what we monitor, differ with age.
| Topic | Children and teens | Adults |
|---|---|---|
| Main goal | Manage myopia as the eye grows, with clear daytime vision as a benefit. Slowing progression is a goal discussed separately from lens licensing. | Temporary daytime correction without glasses or contacts. |
| Who handles lenses | A parent should be involved. Nightly insertion, removal and cleaning have to be done reliably. | The patient, who must commit to nightly wear and disciplined hygiene. |
| Prescription | Often still changing, so the plan is revisited as the eye grows. | Usually more stable, so the main question is correction and comfort. |
| Monitoring | Vision, corneal health and prescription change are checked at visits your doctor schedules. | Vision and corneal health are checked at visits your doctor schedules. |
| Alternatives | Atropine eye drops, MiSight contact lenses, glasses. | Glasses, daytime contact lenses, or surgical consultation elsewhere. |
Myopia, or nearsightedness, usually develops in childhood when the eye grows too long or the cornea becomes too steep. Glasses correct it but do not address why it is progressing. Our practice offers several strategies for managing myopia progression, with orthokeratology as one of them.
Two questions to keep separate. Does the lens give clear vision during the day (refractive correction)? And does it slow progression of nearsightedness (myopia management)? Ask your doctor which goal a treatment is being used for and what evidence supports it for your child.
Holding books and screens close, squinting, difficulty reading at a distance, frequent headaches or eye strain, watery eyes.
A comprehensive eye exam is needed to confirm the prescription and see whether Ortho-K is right for your child.
Our practice offers a free myopia assessment questionnaire. It is a starting point, not a diagnosis. Take the myopia assessment.
Dr. Anith Pillai has a special interest in helping children manage myopia progression and holds fellowship in an orthokeratology and myopia control academy, as described on our team page.
Adults who want to be free of glasses or contacts during the day sometimes choose Ortho-K. The correction fades if you skip nights, and it works best for lower amounts of nearsightedness. Your doctor measures corneal shape and explains your range of correction.
Overnight wear carries a risk of eye infection. Serious infections are uncommon but can damage vision. Hygiene is the foundation of safe Ortho-K.
Wash and dry hands before handling lenses. Use only the solutions your doctor specifies. Never use tap water. Keep the case clean and replace it as directed.
Remove lenses and call your office for pain, redness, discharge, light sensitivity or blurred vision that does not clear quickly.
Your doctor checks corneal health and vision at scheduled visits. The timing is individual, so we do not give one set schedule.
Stopping lens wear lets the cornea return toward its original shape. Tell your doctor before you stop so you can plan next steps.

Good candidates are usually people with mild to moderate nearsightedness, healthy corneas and the ability to follow a nightly routine. Others may be better served by daytime lenses or glasses. Your exam decides.

Orthokeratology uses special lenses worn overnight to gently reshape the cornea, so you can see without glasses or contact lenses during the day. The lenses are removed in the morning.
Not exactly. Ortho-K lenses are licensed for refractive correction, meaning clearer daytime vision. Slowing myopia progression in children is a separate goal. Your doctor will explain what evidence and labeling apply to a given treatment and discuss alternatives.
Overnight lens wear carries a risk of eye infection, which can be serious and can threaten vision. Safe use depends on good hygiene, proper case and solution care, and regular check-ups. Contact your office promptly for pain, redness, discharge or blurred vision.
No. The effect is temporary. If you stop wearing the lenses, the cornea gradually returns toward its original shape, so you must keep wearing them as directed to keep the correction.
No. A comprehensive exam is needed first. Your doctor considers the prescription, corneal shape, eye health, and whether the child and family can handle nightly care reliably.
Our practice also mentions atropine eye drops and MiSight contact lenses as options for managing myopia progression. Which is suitable depends on your child's exam, and offices may differ in what they offer.
Ask your nearest office whether it fits Ortho-K and which myopia management options it offers.
Every exam is individual. Your office confirms suitability and likely benefits. Please confirm which testing and treatments are available at the office you choose.
