If you're tired of glasses and daily contacts, you've probably considered both Ortho-K and LASIK. They both promise freedom from corrective eyewear — but they work in completely different ways and suit very different people. Here's an honest, side-by-side comparison to help you decide.
The Basics: How Each Works
Ortho-K (Orthokeratology)
Custom rigid lenses worn overnight gently reshape your cornea while you sleep. Remove them in the morning and see clearly all day. The effect is temporary — wear the lenses each night for ongoing correction. Fully reversible.
LASIK (Laser-Assisted In Situ Keratomileusis)
A laser permanently reshapes your cornea in a one-time surgical procedure. The entire procedure takes about 15 minutes. Results are typically permanent, though some patients need enhancement procedures years later.
Head-to-Head Comparison
- Age requirement: Ortho-K — suitable from age 6 upward. LASIK — must be 18+ with a stable prescription for at least 12 months
- Permanence: Ortho-K — fully reversible; stop wearing lenses and your vision returns to its previous state. LASIK — permanent corneal change
- Procedure: Ortho-K — no surgery, just lens fitting. LASIK — outpatient surgery with anaesthetic eye drops
- Cost (NZ): Ortho-K — $2,275 initial + $1,600/year for replacement lenses. LASIK — $4,000-$6,000 per eye (one-time)
- Recovery: Ortho-K — progressive over 1-2 weeks. LASIK — most patients see clearly within 24 hours
- Prescription range: Ortho-K — up to about -6.00 myopia. LASIK — can treat higher prescriptions (varies by clinic)
- Myopia control: Ortho-K — yes, proven to slow progression in children. LASIK — no; it corrects existing myopia but doesn't slow progression
- Dry eye risk: Ortho-K — minimal. LASIK — temporary dry eye is common for 3-6 months post-surgery; some patients experience longer-lasting dryness
- Reversibility: Ortho-K — completely reversible. LASIK — not reversible
When Ortho-K Is the Better Choice
- You're under 18 — LASIK isn't an option yet
- Your child has progressing myopia — Ortho-K is one of the best myopia control tools available
- You want a non-surgical option — no cutting, no lasers
- Your prescription is still changing — Ortho-K adapts as your eyes change; LASIK requires a stable prescription
- You're nervous about permanent surgery — Ortho-K lets you "try" clear vision without commitment
- You have mild to moderate myopia (up to -6.00) — this is Ortho-K's sweet spot
When LASIK Is the Better Choice
- You're over 18 with a stable prescription — and want a one-time fix
- You don't want to deal with nightly lens wear — LASIK is a set-and-forget solution
- You have higher myopia (above -6.00) — LASIK can typically treat higher prescriptions
- Long-term cost matters — LASIK is more expensive upfront but has no ongoing costs
- You're comfortable with surgery — the procedure is quick, well-established, and has a high satisfaction rate
Can You Do Ortho-K Now and LASIK Later?
Absolutely — and many patients do exactly this. Ortho-K is particularly popular as a bridge solution: children and teenagers use it for myopia control and glasses-free living, then consider LASIK once they're old enough and their prescription has stabilised.
Because Ortho-K is fully reversible, it doesn't affect your eligibility for LASIK in the future. Simply stop wearing the lenses for 2-4 weeks, let your cornea return to its natural shape, and proceed with a LASIK assessment.
