What does this child myopia-control cost calculator do?

Childhood myopia management often involves more than one initial payment.
Orthokeratology, commonly called Ortho-K, can involve an initial lens set, examinations, cleaning and storage supplies, scheduled replacement, and a reserve for loss or damage.
Low-dose atropine can create a recurring prescription and dispensing payment, while myopia-control glasses and soft contact lenses have their own replacement or monthly purchasing cycles.
This calculator converts the family's current Korean quotes into 1-year, 3-year, and selected growth-period budgets.

The result is a cost comparison, not a treatment ranking.
The model does not convert myopia-control efficacy, axial-length change, visual outcome, adherence, or adverse-event risk into money.
The lowest total is not presented as the best option for a child.
An ophthalmologist must determine clinical suitability and any combined plan; this tool only budgets the plan already discussed.

Korea-specific pricing rule

The current Ministry of Health and Welfare Notice No. 2026-38 lists multiple refractive-correction lenses in the non-covered reporting and disclosure schedule.
A listed item does not have one nationwide price, and a provider package can differ in whether examination, fitting, or early follow-up is included.
Every price therefore starts at zero and must be replaced with the provider's itemized patient-payment quote.
Zero means no quote entered; it does not mean free care.

Four budget paths

Orthokeratology

  • Initial eye and fitting workup paid by the family.
  • Per-eye Ortho-K quote multiplied by one or two eyes.
  • Scheduled lens-set purchases within the planning period.
  • Monthly cleaning, storage, case, and related care supplies.
  • A user-entered expected reserve for loss or damage.
  • Shared follow-up care and optional ordinary backup glasses.

Low-dose atropine

  • Monthly prescription and dispensing payment stated by the clinic or pharmacy.
  • Shared initial examination and follow-up care.
  • Optional ordinary glasses for optical correction.
  • No calculator-selected concentration, dosing schedule, or efficacy assumption.

Myopia-control glasses

  • Current quote for one complete pair.
  • User-entered replacement interval for prescription change, growth, or damage planning.
  • No separate ordinary backup-glasses charge in this method total.
  • A pair quote stays one pair and is not multiplied by the eye count.

Myopia-control soft contact lenses

  • Monthly per-eye quote multiplied by the number of eyes.
  • Months actually purchased or worn in each year.
  • Shared examinations and optional ordinary backup glasses.
  • No automated product selection or wearing-time recommendation.

Official Korean evidence used by the calculator

KDCA health guidance updated May 7, 2026

The Korea Disease Control and Prevention Agency health portal explains that Ortho-K temporarily reshapes the cornea during sleep and may help slow axial-length growth in children and adolescents.
It also notes limits in long-term evidence and substantial individual variation, so the calculator applies no fixed efficacy rate.
The portal identifies visual acuity, slit-lamp examination, corneal topography, and refraction among the pre-fitting checks.
It advises an early review after fitting and continued reviews every few months, with the actual schedule set by the eye clinic.

The approximately 24-month replacement guide is not a deadline

KDCA says Ortho-K lenses are often replaced after about two years, but it does not impose a universal replacement date.
A scratched or deformed lens, reduced correction, or repeated decentration can require earlier review and replacement.
The calculator uses 24 months only as an editable starting interval and always defers to the provider's examination and instructions.

Non-covered reporting codes

Ministry of Health and Welfare Notice No. 2026-38 took effect on February 23, 2026.
Its current Annex 1 lists refractive-correction lenses including the following public reporting codes.

  • 4Z0440101 CONTEX OK.
  • 4Z0440201 and 4Z0440202 Euclid lines.
  • 4Z0440301 through 4Z0440303 Ortho-K LK-Lens lines.
  • 4Z0440401 and 4Z0440402 Paragon CRT 100 lines.
  • 4Z0440601, 4Z0440701, 4Z0440801, 4Z0440901, and 4Z0441001.

These codes establish that the listed lens items are in the non-covered reporting and disclosure system.
They do not create one official national price and do not determine the benefit status of every examination or follow-up line on an individual bill.

How to enter the quotes correctly

Age and planning horizon

Current age is used to label the end of each budget year.
The planning horizon can run from 1 to 15 years, but it does not predict when treatment should stop.
When the selected period extends beyond age 19, the calculator reminds the family to recheck the adult care plan and future pricing.

Per-eye versus both-eye pricing

Enter an Ortho-K or soft-lens quote for one eye and then select one or two eyes.
If the provider has quoted one bundled both-eye package, ask for the per-eye amount or divide the true lens portion carefully before entry.
A glasses quote is already a complete pair and is never halved or doubled by the eye selector.

Avoid package duplication

Check whether the Ortho-K package already includes the initial examination, fitting, early lens exchange, or early follow-up visits.
An included item must not be entered again as a shared examination or follow-up payment.
Ask the provider to identify the lens item, clinical services, exchange terms, and any separately billed supplies.

Price growth and loss reserve

The annual price-growth rate is a household budgeting assumption, not an official inflation forecast.
It is applied from year two to costs that occur in that year.
The Ortho-K loss or damage rate is also a user-defined expected reserve, not a published probability for an individual child.
Keeping both values at zero gives a current-price, scheduled-purchase budget.

Formulas and replacement boundaries

Scheduled purchase count

Month zero is the initial purchase, and another purchase occurs at each entered replacement interval while that month remains inside the plan.
The count is ceil(plan months / replacement months).
With a 24-month interval, a 12-month plan has one purchase, a 24-month plan also has one, a 25-month plan has two, and a 36-month plan has two.
A replacement due exactly at the end of the planning period belongs outside that period.

Cost totals

  • Ortho-K: shared care + scheduled lens sets + monthly care supplies + expected loss reserve + applicable backup glasses.
  • Atropine: shared care + monthly prescription and dispensing cost + applicable backup glasses.
  • Myopia-control glasses: shared care + scheduled pairs, with no separate ordinary backup-glasses charge.
  • Soft lenses: shared care + per-eye monthly cost × eyes × months purchased + applicable backup glasses.
  • Monthly equivalent: selected-period total divided by the number of months in the plan.

A combined plan counts shared initial and follow-up care once, then adds each selected method's unique cost.
Backup glasses are also counted once and are removed when myopia-control glasses already provide the optical correction in the combination.

Worked 3-year example

The figures below are hypothetical inputs used to demonstrate the formulas; they are not Korean national averages.
The child is age 8, the plan covers both eyes for 3 years, and price growth is 0 percent.
Shared costs are KRW 100,000 for the initial examination, four follow-ups per year at KRW 30,000, and ordinary backup glasses at KRW 200,000 every 12 months where applicable.

Hypothetical three-year child myopia-control budget comparison
MethodHypothetical quoteYear 13-year total
OrthokeratologyKRW 500,000 per eye, 24 months, KRW 20,000 monthly care, 10% reserveKRW 1,760,000KRW 4,080,000
Low-dose atropineKRW 30,000 per monthKRW 780,000KRW 2,140,000
Myopia-control glassesKRW 600,000 per pair, 12-month intervalKRW 820,000KRW 2,260,000
Myopia-control soft lensesKRW 40,000 per eye monthly, 12 months each yearKRW 1,380,000KRW 3,940,000

In this example, two Ortho-K sets cost KRW 2,000,000, three years of care supplies cost KRW 720,000, and the expected loss reserve is KRW 300,000.
Shared care is KRW 460,000 and applicable backup glasses cost KRW 600,000, producing the KRW 4,080,000 Ortho-K total.
An Ortho-K plus atropine combined plan is KRW 5,160,000 because shared care and backup glasses are counted once rather than once per method.

Step-by-step use

  1. Set the budget period. Enter the child's current age and the number of years the family wants to plan.
  2. Separate shared care. Enter the initial workup and the provider-stated annual follow-up schedule once.
  3. Check the quote unit. Confirm whether each Ortho-K or soft-lens price is for one eye or both eyes.
  4. Enter recurring cycles. Add the lens or glasses replacement interval, monthly medication, monthly supplies, and months of soft-lens purchasing.
  5. Remove duplicated package items. Do not enter an examination twice when the lens package already contains it.
  6. Select a clinician-described combination. The combined total shares examinations and backup glasses without recommending a treatment pair.
  7. Review year one, year three, and the full period. A method with a large initial purchase and a method with a monthly recurring charge can have very different cash-flow patterns.

Safety comes before the budget

Lens care is not an optional cost category

KDCA explains that the cornea and conjunctiva must be suitable before overnight lens wear and that regular eye review remains necessary after fitting.
Poor hygiene can increase the risk of microbial keratitis, which can cause permanent visual harm.
The calculator never suggests reducing cleaning supplies or skipping follow-up care to make a plan look cheaper.

  • Do not rinse the lens with tap water; follow the eye clinic's cleaning and storage instructions.
  • Wash and dry hands before insertion or removal and follow replacement instructions for solution and cases.
  • Redness, discharge, pain, or reduced vision requires prompt eye examination rather than continued cost comparison.
  • Scratches, deformation, poor correction, or repeated decentration require provider review even before the planned replacement month.
  • Do not start overnight lenses from a budget result when the child cannot safely manage wear and care.

Frequently asked questions

Must every Ortho-K lens be replaced at 24 months?

No.
KDCA describes about two years as a common replacement experience, not a mandatory lifetime.
Lens condition, correction, fit, and the eye examination control the actual timing, so replace the starting interval with the provider's plan.

Does the calculator automatically apply Korean National Health Insurance?

No.
The current public schedule identifies multiple refractive-correction lens products as non-covered reporting items, but a bill can contain separate examination and clinical-service lines.
Enter the actual patient payment quoted by the provider instead of entering a covered total and applying a guessed copay rate.

What loss or damage percentage should I use?

The calculator does not prescribe one.
There is no official personal accident probability in this model, so the default is 0 percent.
A family can enter a hypothetical reserve based on its own cash-flow tolerance, but the result remains an expected budget and not a forecast.

Should the family choose the cheapest method?

No.
This model does not score efficacy, indication, side effects, corneal suitability, adherence, or the child's and caregiver's ability to manage a lens.
Use the medical examination to choose or review a plan, then use the calculator to prepare the budget for that plan.

Does the total subtract private insurance or a tax credit?

No uncertain reimbursement is subtracted automatically.
Korean private-insurance coverage and medical-expense tax treatment can depend on the contract, medical purpose, prescription, receipt, and household tax facts.
Verify those items with the insurer or tax guidance and keep them separate from this provider-cost budget.

Legal basis, sources, and update date

The calculator and source review are current as of July 24, 2026.
Prices, public reporting codes, product status, and benefit treatment can change, so recheck the provider's current disclosure, exact product, and package scope before starting or replacing a lens.
This Korea-based planning tool is not medical advice, an insurance decision, or a guarantee of future price or clinical outcome.
