Inputs to confirm

  • Every amount is zero. Treat zero as unentered, not as free care.
  • Multifocal IOL: Both the main initial quote and initial extras are zero.
  • Multifocal IOL: Confirm eyes, tests, medication, follow-up, glasses, and enhancement scope.
  • Presbyopia laser: Both the main initial quote and initial extras are zero.
  • Presbyopia laser: Confirm eyes, tests, medication, follow-up, glasses, and enhancement scope.
  • Glasses: Both the main initial quote and initial extras are zero.
  • Glasses: Confirm eyes, tests, medication, follow-up, glasses, and enhancement scope.

An ophthalmologist must determine cataract status and clinical suitability. Enter insurance and tax offsets only after checking policy, care setting, documents, and the applicable tax year.

Why the first payment is not a lifetime comparison

An advertised surgery price or the checkout price of one pair of glasses can omit tests, medication, dry-eye care, follow-up visits, supplementary glasses, replacement, and a possible enhancement.
A pathway with a large first payment and a pathway with recurring payments may reverse order between year 5 and year 20.
This calculator places a multifocal intraocular-lens pathway, a presbyopia-laser or refractive-surgery pathway, and continued glasses use on the same monthly timeline.

A lower present-value cost does not mean better vision, safer care, faster recovery, or clinical suitability.
Cataract status, corneal and retinal health, dry eye, night driving, occupation, and visual goals need a separate ophthalmologist assessment.
Use the result as a missing-cost and cash-reserve worksheet before consultations, never as a treatment-selection score.

Define the three pathways before entering money

Multifocal IOL pathway

Enter an actual one-eye or two-eye quote only after a clinician has discussed cataract surgery or lens exchange in your case.
Confirm whether the amount includes the specific lens, tests, facility, anesthesia, medication, follow-up, and supplementary glasses.
The calculator cannot decide whether lens surgery is appropriate when cataract is absent.

Presbyopia laser pathway

Use the final scope-aligned quote for the refractive method discussed after examination, not an advertisement's starting price.
Ask about both eyes, tests, medication, follow-up, dry-eye care, supplementary glasses, and enhancement terms.
Reading glasses or additional treatment may still be needed, independently of the budget ranking.

Continue with glasses

Enter the real frame-and-lens total for the first pair, plus examination, fitting, supplies, and later replacement.
Keep lens grade and frame scope reasonably comparable with any supplementary glasses entered for a surgical pathway.
Use your replacement history rather than assuming a universal lifespan.

These pathways are not equal units of clinical effect.
If an ophthalmologist says a pathway is unsuitable, its lower cost cannot put it back into the decision set.

How the monthly cash model works

Initial and recurring events

Month 0 combines the main quote and initial extras, then subtracts only confirmed insurance and tax offsets up to that initial cost.
Monthly care begins in month 1, annual follow-up occurs every 12 months, and replacement occurs at the entered cycle through the selected horizon.
A surgical pathway can include one enhancement event at the entered month, while the glasses pathway ignores enhancement fields.

Growth and present value

Future care, follow-up, replacement, and enhancement amounts grow by the user-entered annual cost-growth assumption on a monthly timeline.
Each future event is then discounted to present value with the annual discount assumption.
The discount rate is not a promised investment return or a forecast of South Korean medical inflation.

Monthly equivalent and cash peak

The monthly equivalent divides period present value by the number of months and is a comparison metric rather than a payment plan.
Peak monthly outflow combines events landing in the same month, which can expose an affordability problem hidden by an acceptable 20-year total.

Future cost = entered amount × (1 + annual growth)month / 12
Present value = future cost ÷ (1 + annual discount rate)month / 12
Monthly equivalent = period present value ÷ period months

Read the outputs in four passes

1. Compare all three horizons

Five years emphasizes near-term cash, while twenty years gives repeated glasses and long-running care more opportunities to accumulate.
Check whether the ranking changes and whether the difference is large enough to survive reasonable input revisions.

2. Inspect cost composition

Separate initial, monthly, annual, replacement, and enhancement cost to identify the assumption driving the gap.
Review peak cash when replacement and enhancement can coincide.

3. Interpret stable break-even carefully

Stable break-even is the first month when a surgical pathway's cumulative present value is no higher than glasses and remains no higher through month 240.
None within 20 years is a valid result, and any crossing is purely financial rather than a recommended surgery date.

4. Stress the enhancement amount

The sensitivity table compares no enhancement cost, 100% of the entered cost, and 125% of the entered cost at the same entered month.
Those rows alter financial impact and do not represent a 0%, 100%, or 125% chance of additional treatment.

The optional synthetic example is not a price guide

The example button inserts fictional values solely to demonstrate the event timeline, present-value math, and output states.
It is not a Korean average, provider quote, treatment recommendation, lens lifespan, glasses-replacement standard, or insurance practice.

Fictional starting values used by the synthetic example

Replace every pathway's values with scope-matched evidence rather than editing only the number that looks unrealistic.
Mixing promotional prices from different dates or different included items can make precise mathematics rest on an unfair comparison.

South Korean quote and non-covered-price boundaries

Public prices are inquiry anchors

Medical Service Act Articles 45 and 45-2 establish non-covered charge posting, reporting, analysis, and public-disclosure mechanisms.
HIRA lets users compare provider-disclosed non-covered prices, including LASIK information, but the publication date and scope may differ from the final one-eye or two-eye bill.
The calculator therefore leaves every real amount at KRW 0 until the user enters a dated quote.

A lens label does not decide a personal bill

The Korean Ministry of Food and Drug Safety performance guide discusses multifocal and accommodating intraocular-lens evaluation, not personal suitability or price.
Medical Care Benefit Rules Article 9 and Appendix 2 provide a legal non-covered framework but do not let this tool adjudicate one patient's lens selection or billing.
Ask for the exact product, benefit status, eye count, and every separately billed item.

Why insurance and tax savings are never automatic

Korean private indemnity reimbursement can depend on medical purpose, inpatient necessity, outpatient status, policy wording, records, and insurer review rather than product generation alone.
Cataract-related judgments and industry criteria do not make every claim identical.
Enter only an amount the insurer confirmed for the same quoted scope, and keep it at zero while review is pending.

Income Tax Act Article 59-4 and Enforcement Decree Article 118-5 require annual context, including the medical-expense threshold above 3% of gross salary and subtraction of indemnity-insurance payments from directly borne expense.
The decree includes vision-correction glasses or contact lenses within a KRW 500,000 per-person annual purchase limit, while cosmetic surgery expenses are excluded.
Actual purpose, evidence, household medical expenses, insurance payments, and tax year are unknown here, so use only a checked tax saving from the responsible records or adviser.
If confirmed insurance and tax offsets together exceed initial cost, the model caps the deduction at initial cost rather than creating negative care cost.

Practical planning scenarios

The first surgery payment is affordable but aftercare is unclear

Ask how long follow-up is included and what later tests, medication, dry-eye care, supplementary glasses, and enhancement conditions cost.
Until those answers exist, treat zero as unentered and use the warning list as consultation questions.

Premium progressive glasses are replaced frequently

Use the last two or three receipts and the actual intervals between them.
Review both prescription-driven and loss-or-breakage replacement so a long-horizon glasses budget is not unrealistically optimistic.

The insurer has not completed review

Save a conservative zero-reimbursement case and a separate case only after receiving a scope-specific confirmation.
Do not copy a friend's reimbursement or a provider's verbal estimate into your confirmed offset.

Cash flow crosses retirement

Compare peak monthly outflow with the expected lower-income period as well as the total.
Recalculate with a low and high growth or discount assumption to create a planning range instead of relying on one precise number.

Clinical safety stays outside the cost ranking

The US Food and Drug Administration advises prospective LASIK patients to discuss dry eye, glare and night-vision problems, incomplete correction, possible additional treatment, and the possibility of still needing reading glasses.
This calculator does not estimate the probability or severity of any outcome.
Sudden vision loss, severe pain, flashes, a sudden increase in floaters, or a curtain over vision requires prompt medical contact rather than financial comparison.

  • How were presbyopia cause and cataract status assessed
  • Does each quote cover one eye or both eyes
  • How do night driving, reading, screen work, and occupation affect expectations
  • How do dry eye, corneal findings, retinal disease, or other eye conditions affect suitability
  • Are tests, medication, follow-up, and supplementary glasses included
  • What triggers enhancement review and what is excluded from any written terms
  • What is the exact multifocal-IOL product and benefit or non-covered classification
  • Which diagnosis, records, receipts, and itemized statements may be needed for a claim

Frequently asked questions

Why are there no default Korean surgery prices?

The same name can cover different eyes, tests, lenses, devices, medication, and follow-up.
Public non-covered information is a comparison starting point rather than a personal final bill, so every actual amount starts at zero.

Does an early break-even mean surgery is preferable?

No.
It is only a crossing of entered cumulative costs and does not compare vision quality, complications, satisfaction, recovery, or suitability.

Can I enter enhancement cost without a month?

The model requires both values and otherwise omits the event with a warning.
When no clinician-confirmed condition exists, keep the base case at zero and label any separate stress scenario as hypothetical rather than inventing a probability.

Can I set glasses cost to zero after a multifocal IOL?

The calculator never guarantees glasses independence.
Ask about expected near, intermediate, distance, and night-driving support, then enter only the supplementary-glasses budget you deliberately want to plan.

Is the KRW 500,000 glasses rule a KRW 500,000 refund?

No.
It is a per-person annual limit on eligible vision-correction glasses or contact-lens purchase expense, while actual tax saving also depends on the 3% salary threshold, other medical expense, insurance payments, and the tax-credit calculation.
