Custom Dream Lens
Dream Lens is an orthokeratology contact lens worn during sleep to correct myopia and astigmatism,
a safe way for children, teens, and adults alike to correct their vision.

Reshapes the cornea during sleep to correct vision

At Gangnam Central Eye Clinic, the Medical Director personally provides examination, prescription, and guidance.
Because Dream Lens corrects myopia and astigmatism by temporarily changing the corneal shape,
patients must fully understand how to use it and the precautions before starting.

FAQ

Dream Lens FAQs

Is it surgery?

No. You wear the lens while sleeping to gently reshape the central cornea, so there is no surgical process.

Is everyone eligible for Dream Lens?

No. We examine corneal shape and thickness, prescription, eyelid and tear film status to determine eligibility. For high myopia or high astigmatism, or strong eyelid tension, it is not recommended. We cannot say whether it is possible without examination results.

Can people with high myopia or high astigmatism wear Dream Lens?

If the prescription is high, the lens may put too much pressure on the cornea or may not stay centered on the cornea. The decision is made based on the values measured in the examination.

When will I start to see well?

It varies by person. The course depends on corneal shape, prescription, and sleep time, so we do not state a fixed period. We check at the scheduled follow-ups.

Can children wear it too?

Consultation is available for children, teens, and adults. However, it is not recommended if allergic conjunctivitis is chronically severe or sleep time is irregular.

Can I wear Dream Lens if I have dry eye?

We check your tear film first. If dryness is severe, we may treat it first and start lens wear later.

Who prescribes it?

Our ophthalmologist personally examines you, prescribes the lens, and guides you on wearing it.

How many hours a day do I need to wear it?

Wear it while sleeping. If sleep time is irregular or less than 6 hours per day, it is not recommended.

What happens if I stop wearing it?

If you stop wearing it, the cornea returns to its original shape. Then you will need glasses or lenses again.

Which is better, surgery or Dream Lens?

It depends on age and eye condition. Dream Lens is not surgery and is reversible, but it requires daily wear; which is suitable is determined through examination and consultation.

If my cornea is too flat or too steep, can’t I use Dream Lens?

If the corneal curvature is below 40 D (too flat) or, conversely, too steep, we do not recommend Dream Lens, because the lens cannot settle stably on the central cornea. Curvature is measured at the first exam, and we advise you based on the results.

Can I just have the exam and decide later?

Yes. You can have the exam first and decide on wearing the lens later. After checking corneal shape and curvature, your prescription, and your eyelids and tear film, we review the results together. We skip unnecessary tests and repeat the important ones to reduce the margin of error.

My child’s myopia is progressing quickly—can my child use Dream Lens?

Dream Lens is a lens that gently reshapes the cornea overnight to correct vision during the day. The speed of myopia progression differs by child; we monitor it with regular checkups, and after the examination we will advise whether it suits your child’s eyes.

Are there cases where Dream Lens is not possible?

If the cornea is too flat or too steep, or if allergic conjunctivitis is severe, it may not be recommended. We first check with corneal topography to see whether the lens design is suitable.

Is Dream Lens custom-made?

After precision testing to check corneal shape and prescription, we make the lens to fit your eyes. When you first wear the lenses, we also provide instructions on use and precautions.
