Ortho-K vs LASIK: Which Vision Correction Is Right for You?

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.
