ICL vs Laser Eye Surgery for High Prescriptions
When a glasses or contact lens prescription sits at the higher end of the range, people often ask whether laser vision correction or an implantable contact lens (ICL) is the better fit. Online comparisons can sound definitive. In clinic, the answer depends on your corneal thickness and shape, the depth of the front of the eye, dry-eye findings, age, lifestyle and the exact refractive error, not a single number on a blog.
At EyeHub on the Sunshine Coast, Dr Sonia Moorthy offers laser pathways including LASIK, SMILE PRO and PRESBYOND, plus ICL and refractive lens exchange (RLE) where clinically appropriate. This article explains how those conversations usually run for higher prescriptions. It is not a personal recommendation.
Any surgical or invasive procedure carries risks.
What “high prescription” usually means in conversation
Clinicians usually refer to −10 D of short-sightedness, +4 D of long-sightedness and 6 D of astigmatism or more as high prescriptions. Astigmatism and mixed prescriptions matter too. Two people with the same spectacle number can have very different corneas.
EyeHub does not use a hard “cut-off” that automatically sends everyone above a certain dioptre to ICL. Detailed diagnostic scans help us decide which option suits your eyes. If laser remains safe and predictable for your eyes, it may still be discussed. If corneal tissue is too thin, lacks adequate biomechanical strength or other findings make laser less suitable, an ICL may be the better option.
Why higher prescriptions change the laser discussion
Laser vision correction reshapes the cornea. Higher corrections generally require more tissue change. That doesn’t make laser “wrong”. Modern screening and planning exist to keep treatment within safe margins, but it does mean your surgeon looks carefully at:
- Residual corneal thickness and biomechanics after a planned treatment
- Predictability of the refractive target at higher powers
- Night-time optical symptoms (glare, halos) and dry-eye risk
- Your work, sport and healing expectations
When those margins are tight, continuing to chase a laser plan is not automatically the patient-centred choice. That’s when an ICL often comes into the discussion. It corrects refractive error with a lens inside the eye, without removing corneal tissue for the correction.
Why an ICL may be discussed for higher prescriptions
An ICL sits in front of the natural lens. For selected adults with a stable prescription and suitable anterior chamber anatomy, it can address higher myopia (and selected other refractive errors) while leaving corneal thickness intact.
Themes we cover in counselling (without promising outcomes):
- No corneal tissue removed for the refractive correction itself
- The lens can usually be removed or exchanged later if clinically indicated, although removal is another operation and doesn’t reverse changes already in the eye
- Because an ICL doesn’t reshape the cornea, some studies suggest the eye surface recovers faster than after corneal laser. The evidence is still limited, and temporary dryness can happen after any eye surgery
- Lifelong monitoring of vault, pressure and corneal health is part of having an intraocular lens
ICL is still intraocular surgery, with its own material risks, although low, including cataract, pressure issues, lens sizing/vault problems, optical symptoms such as halos, and gradual loss of the cells lining the cornea. Advanced imaging and sizing algorithms now help select the ICL size, one of the important recent advances. Elements relevant to you are explained at consultation and the informed consent discussion.
Laser options at EyeHub (when they still suit)
For many low-to-moderate prescriptions with healthy corneas, laser remains a common first discussion:
| Procedure | Plain-language role |
|---|---|
| LASIK | Flap-based corneal reshaping; relatively quick early visual recovery for many suitable patients |
| SMILE PRO | Small-incision lenticule extraction; flap-free approach discussed for selected myopia/astigmatism profiles; often discussed for people in contact sports, as there is no flap |
| PRESBYOND | Laser blended vision for people over 40 with reading difficulty (presbyopia) |
Published fees
| Pathway | Published EyeHub figure |
|---|---|
| PRESBYOND | $8,800* both eyes |
| SMILE PRO | $7,800* both eyes |
| LASIK | $7,800* both eyes |
Laser package inclusions (all pre- and post-operative assessments, post-operative drops, 12 months aftercare and lid serum).
*Includes surgeon, anaesthetic and hospital fees.
| Pathway | Published EyeHub figure |
|---|---|
| RLE | Approximate $13,000 both eyes* |
| ICL | Approximate $14,000 both eyes* |
*Includes surgeon, lens, anaesthetic and hospital fees.
Who usually starts where (guide only)
| Clinical picture (examples) | Often discussed first |
|---|---|
| Low to moderate myopia, thick healthy corneas | Laser (LASIK / SMILE PRO as suited) |
| Higher myopia, thin corneas or laser margins tight | ICL assessment conversation |
| Presbyopia, up to age 60 | PRESBYOND |
| Presbyopia, above age 60 | RLE |
| Anterior chamber too shallow or contraindication to ICL | Other considerations |
This table is a teaching aid, not a triage algorithm. Your assessment overrides it.
Assessment pathway
EyeHub uses one laser vision assessment pathway:
- Free online video assessment
- In-person assessment with a $100 deposit (redeemable against your surgery)
You will be assessed by the Laser Refractive Clinical team, led by a highly experienced Refractive Optometrist. If suitable to proceed, you will be offered surgery and have an additional discussion with Dr Moorthy.
If found unsuitable for laser, a separate consultation* with Dr Moorthy will be advised.
Clinics: Buderim (Unit 1, Building A, 23 Elsa Wilson Dr, Buderim QLD 4556) and Noosaville (197 Weyba Road, Noosaville QLD 4566).
*Consultation fee of $350 will apply.
FAQs
Is ICL always safer than LASIK for high myopia?
No absolute claim. In a review of trials in people with about −6 to −20 D of short-sightedness, lens implants were less likely than laser to reduce best-corrected vision at one year, and patients preferred them. Longer-term comparisons are limited, and both options carry risks. Your eyes, health and measurements decide. We don’t use unsourced “safer for everyone” language.
Can I still have laser if my prescription is high?
Sometimes, yes, if corneal and refractive planning stay within safe, predictable limits. Sometimes no. Assessment answers that.
Does ICL include free laser enhancements?
No. EyeHub does not market enhancements as part of ICL. Dr Moorthy’s aim is to get it right the first time, which is why the assessment is so thorough. However, Dr Moorthy will discuss options with you if the result does not reflect the planned target.
