Dream Lens (Ortho-K) in Seomyeon, Busan
Dream Lens (orthokeratology, ortho-k) uses custom rigid gas-permeable lenses worn overnight to gently reshape the cornea, so you can see clearly during the day without glasses or contacts. In Seomyeon, eye clinics map the cornea, fit trial lenses and teach handling; most wearers see clear daytime vision within 1–2 weeks. It is widely used for myopia control in children.

What is Dream Lens?
Orthokeratology lenses have a special reverse-geometry design that flattens the centre of the cornea while you sleep. When removed in the morning, the cornea holds this shape for the day, correcting nearsightedness. The effect is reversible: if you stop wearing the lenses, the cornea returns to its original shape over days to weeks. In children, ortho-k has also been shown to slow the elongation of the eye that drives myopia progression.
Who is it for?
- Children and teens with progressing myopia, as part of myopia control
- Adults who want glasses-free daytime vision without surgery
- Swimmers and athletes who dislike glasses or daytime contacts
- People not yet suitable for laser surgery
High prescriptions, significant astigmatism, dry eye or poor hygiene habits may make ortho-k unsuitable.
What happens at the clinic
- Eye exam: refraction, corneal topography, tear film and eye health check.
- Trial fitting: trial lenses are assessed with fluorescein dye for fit.
- Custom order: lenses are designed and ordered for each eye.
- Training: insertion, removal, cleaning and storage are taught; parents learn to supervise children.
- Follow-up: a morning-after check, then scheduled visits to review vision, topography and corneal health.
Recovery and aftercare
Vision gradually improves over the first week or two. Clean lenses daily as instructed with recommended solutions; never use tap water. Replace cases regularly and lenses per the clinic's schedule, often yearly. Do not sleep in lenses if your eyes are red or painful.
Risks and side effects
The most important risk is microbial keratitis, a corneal infection that can threaten vision, usually linked to poor hygiene or tap water. Other issues include temporary glare, halos, lens binding and fluctuating vision late in the day.
Choosing a clinic for Dream Lens in Seomyeon
- Ask whether corneal topography is used for fitting and follow-up.
- Ask which lens designs are available and how they are customised.
- Ask how hygiene training is done and what to do if the eye becomes red.
- Ask how often lenses and cases should be replaced.
- For children, ask how axial length is tracked to assess myopia control.

Frequently asked questions
Is Dream Lens safe for children?
It is generally considered safe when properly fitted and with strict hygiene. The main risk is corneal infection, so careful cleaning and supervised use are essential.
How quickly does Dream Lens work?
Many people notice improvement after the first night, with stable clear daytime vision typically within one to two weeks.
Is ortho-k permanent?
No. The cornea gradually returns to its original shape if lenses are stopped, so regular overnight wear is needed to maintain the effect.
Does ortho-k slow myopia in children?
Studies show ortho-k can slow eye elongation and myopia progression in many children, though results vary between individuals.
What should I do if my eye is red with Dream Lens?
Stop wearing the lenses and contact your eye clinic promptly. Pain, redness, light sensitivity or blurred vision may indicate infection and need urgent assessment.
