Understanding High Myopia and Astigmatism
If you’ve been told your prescription is too high for LASIK, you’re not alone. Many patients with severe nearsightedness struggle to find a vision correction solution that actually works for their eyes. The good news? EVO ICL™ is designed for exactly this — correcting high prescriptions with a procedure that works with your eye’s natural anatomy. Whether you’re in Reno or the surrounding areas of Sparks, Carson City, Truckee, Fernley, Fallon, North Lake Tahoe, Incline Village, or Susanville, Nevada Eye Consultants is here to help.
What Causes High Myopia and Astigmatism?
High myopia refers to nearsightedness of -6.00 diopters or greater, making distant objects appear blurry while close-up vision remains clear. Astigmatism occurs when the cornea or lens has an irregular shape—more like a football than a sphere—scattering light in multiple directions. When combined, these conditions create significant vision challenges.
When EVO ICL May Be the Right Fit
LASIK works by reshaping the cornea with a laser — an excellent approach for many patients. For those with higher prescriptions, though, corneal anatomy sets natural limits on how much correction is possible. EVO ICL takes a different approach entirely, working inside the eye rather than on its surface.
What is EVO ICL Surgery?
EVO ICL (Implantable Collamer Lens) is a proven vision correction procedure that works differently than LASIK. Instead of reshaping your cornea, EVO ICL places a thin, prescription-correcting lens inside your eye—positioned between your iris and your natural lens.
The lens is made of Collamer, a biocompatible material that your eye accepts naturally without triggering rejection or inflammation. Think of it as a contact lens that lives inside your eye — no insertion, no removal, no daily care.
How EVO ICL Works
During the procedure, your surgeon creates a small opening in your eye and gently inserts the folded EVO ICL lens. Once positioned, the lens unfolds and settles into place, immediately correcting your vision. The entire process takes less than 15 minutes per eye.
The beauty of EVO ICL is that it works with your eye’s natural anatomy rather than against it. Your cornea remains untouched, preserving its structural integrity and allowing for future vision changes or adjustments if needed.
Can EVO ICL Correct High Myopia?
Yes — and it’s specifically designed for the higher prescription ranges where corneal surgery reaches its natural limits.
EVO ICL can correct myopia ranging from -3.00 to -20.00 diopters, making it ideal for patients with severe nearsightedness. This prescription range far exceeds what LASIK can safely achieve, which typically maxes out around -12 diopters.
Why EVO ICL Works for High Myopia
- No corneal tissue removal: EVO ICL doesn’t reshape your cornea, eliminating concerns about structural weakness or ectasia (corneal bulging)
- Stable, long-term results: Clinical studies show that EVO ICL corrections remain stable for 10+ years
- Flexible: If your vision changes or your needs shift, your surgeon can adjust or remove the lens without permanent corneal alteration
- Exceptional visual quality: Patients often achieve 20/20 vision or better, with crisp clarity even in low-light conditions
Can EVO ICL Correct Astigmatism?
Absolutely—with the EVO Toric ICL.
For patients with astigmatism, the EVO Toric ICL is specifically designed to address this refractive error. It can correct astigmatism up to 4.00 diopters while simultaneously correcting myopia up to -20.00 diopters.
EVO Toric ICL Advantages
The Toric version includes special markings and a unique lens design that accounts for astigmatism’s directional nature. Your surgeon uses these markings to position the lens at the precise angle needed to correct your specific astigmatism.
This means you get comprehensive vision correction in a single procedure—no compromises, no residual blur.
Key Advantages of EVO ICL for High Myopia and Astigmatism
1. Wider Prescription Range
EVO ICL corrects prescriptions that LASIK cannot safely handle. If you’ve been told you’re “not a candidate” for LASIK, EVO ICL may be your solution.
2. Flexibility
EVO ICL is removable. If your vision changes due to aging or other factors, your surgeon can adjust or remove the lens without permanent corneal changes.
3. Corneal Preservation
Your cornea remains completely intact. This is especially important for patients with thin corneas or those concerned about long-term corneal health.
4. Exceptional Visual Outcomes
In a patient survey, 99.4% of EVO ICL patients reported they would have the procedure again. This high satisfaction rate reflects the exceptional results patients experience with EVO ICL vision correction.
5. Stable, Long-Term Results
EVO ICL provides stable vision correction for 10+ years. Your prescription doesn’t regress or shift over time like some other procedures.
6. Minimal Dry Eye
Because EVO ICL preserves corneal nerves, patients typically experience minimal post-operative dry eye.
7. Quick Recovery
Most patients notice improved vision within 24-48 hours. You can return to normal activities within a few days, though strenuous exercise should wait 1-2 weeks.
The EVO ICL Procedure: What to Expect
Pre-Operative Evaluation
Before surgery, you’ll undergo comprehensive eye testing to determine your exact prescription, corneal shape, and eye measurements. Your surgeon will also assess your eye health and confirm you’re a suitable candidate.
This evaluation typically takes 1-2 hours and is painless. Nevada Eye Consultants in Reno offers convenient scheduling to serve patients throughout Northern Nevada.
The Surgery Itself
On surgery day, you’ll receive numbing eye drops—no injections needed. Your surgeon will:
- Create a small opening (2-3mm) in your eye
- Insert the folded EVO ICL lens through this opening
- Position the lens behind your iris
- Allow the lens to unfold and settle into place
The entire procedure takes 20-30 minutes per eye. You’ll be awake but comfortable, and you won’t feel pain—only mild pressure sensations.
Recovery Timeline
- Day 1: Vision improves noticeably; mild grittiness or light sensitivity is normal
- Week 1: Most patients achieve functional vision; avoid swimming and strenuous activity
- Week 2-4: Vision stabilizes; you can resume most normal activities
- Month 3: Final visual stability; all restrictions lifted
Who is a Suitable Candidate for EVO ICL?
Not everyone is a candidate for EVO ICL, but the criteria are broader than for LASIK. You may be a good candidate if you:
- Are between 21-60 years old
- Have a stable prescription for at least 1 year
- Have high myopia (-3.00 to -20.00 diopters) or myopic astigmatism
- Have astigmatism up to 4.00 diopters (with the Toric version)
- Have healthy eyes with no corneal disease or retinal problems
- Are not pregnant or nursing (pregnancy can temporarily change vision)
- Have realistic expectations about vision correction outcomes
Why Age Matters
EVO ICL works best for patients whose prescriptions have stabilized. If you’re still experiencing significant prescription changes year-to-year, your surgeon may recommend waiting.

Frequently Asked Questions
How long does EVO ICL last?
EVO ICL is designed to be permanent, with clinical data supporting stability for 10+ years. Many patients keep their lenses for life, though removal or replacement is always an option.
Will I feel the EVO ICL in my eye?
No. Once healed, you won’t feel the lens at all. It becomes part of your eye and functions seamlessly with your natural vision.
Can I have LASIK after EVO ICL?
Yes. If you want additional vision correction after EVO ICL, LASIK can be performed on the cornea. EVO ICL and LASIK can work together — corneal laser correction remains an option down the road if your vision needs evolve.
What if my vision changes after EVO ICL?
If your prescription shifts significantly (rare after age 40), your surgeon can adjust or replace the lens. This reversibility is a key benefit over LASIK.
Is EVO ICL covered by insurance?
Most insurance plans don’t cover elective vision correction procedures like EVO ICL. However, many surgeons offer financing options to make the procedure more affordable.
How much does EVO ICL cost?
EVO ICL typically costs $3,500-$4,000 per eye, depending on your location and surgeon. While higher than LASIK, many patients consider it a strong investment for their specific prescription needs.
Can EVO ICL be removed if I change my mind?
Yes. EVO ICL is fully reversible. If you want the lens removed for any reason, your surgeon can do so in a simple outpatient procedure. The procedure can be reversed without permanent corneal alteration.
Will I need reading glasses after EVO ICL?
EVO ICL corrects distance vision. Like all vision correction procedures, you may need reading glasses as you age (presbyopia), typically starting around age 40-45. This is a natural part of aging, not a failure of the procedure.
How does EVO ICL compare to implantable contact lenses (ICL)?
EVO ICL is an implantable contact lens—the newest generation. It’s an improvement over older ICL technology with better optical quality, wider prescription range, and enhanced safety features.
What happens if I develop cataracts after EVO ICL?
EVO ICL doesn’t increase cataract risk. If cataracts develop (a natural aging process), your surgeon can remove them and adjust or replace your EVO ICL as needed.
Take the Next Step Toward Clear Vision
If you have high myopia or astigmatism, EVO ICL may be the right fit — particularly for patients whose prescriptions fall outside the range where corneal surgery is most effective. With its ability to correct extreme prescriptions, reversibility, and exceptional visual outcomes, it’s transforming vision correction for patients who thought their options were limited.
