Myopia, commonly known as nearsightedness, affects many Canadians and continues to become more common across younger generations. At Clearview Optical Calgary, patients often ask whether glasses and contact lenses are their only long-term option. For the right candidate, long-term myopia correction can reduce daily dependence on corrective eyewear and make clear distance vision feel much more achievable.
The key word is correction. Current treatments do not remove myopia at the biological level. Instead, they reshape the cornea, add an internal corrective lens, or replace the eye’s natural lens so that light focuses properly on the retina. For many patients, the result feels very similar to a cure because they can see clearly without relying on everyday glasses or contacts.
This guide explains the main evidence-based options for long-term myopia correction, who each option may suit, and what to discuss with a Calgary optometrist before choosing a procedure.
Not Sure Which Myopia Option Fits Your Eyes?

What Causes Myopia and Nearsightedness?
Myopia happens when the eye is slightly too long from front to back, or when the cornea is too steeply curved. In both cases, incoming light focuses in front of the retina instead of directly on it. This creates clear near vision and blurred distance vision.
Myopia is measured in dioptres. Mild myopia usually falls between -0.25 and -3.00 D, moderate myopia between -3.00 and -6.00 D, and high myopia beyond -6.00 D. This number matters because not every correction option is suitable for every prescription.
High myopia can increase the risk of certain eye conditions, including retinal detachment and glaucoma. If your prescription is above -6.00 D, a detailed retinal evaluation should be part of your consultation.
Laser Eye Surgery for Myopia in Calgary
Laser surgery remains one of the most widely used categories of permanent myopia correction. For many patients with mild to moderate myopia and healthy corneas, it can provide reliable long-term results.
LASIK for Nearsightedness
LASIK is the procedure many people picture when they think about laser eye surgery. A thin corneal flap is created, the underlying tissue is reshaped with a laser, and the flap is repositioned. Many patients notice significant improvement within 24 hours.
LASIK may be suitable for some prescriptions up to approximately -10.00 D, depending on corneal thickness, tear film health, and overall eye structure. It may not be recommended for patients with thin corneas, dry eye concerns, or certain corneal irregularities.
PRK for Myopia Correction
PRK uses the same reshaping concept as LASIK but does not create a flap. Instead, the outer surface layer of the cornea is removed before the laser reshapes the tissue underneath. Recovery is longer, often involving one to three weeks of visual fluctuation.
PRK may be preferred for patients with thin corneas, high-contact occupations, or active lifestyles where flap-related concerns are more relevant.
SMILE Laser Eye Surgery
SMILE uses a femtosecond laser to create and remove a small lens-shaped piece of corneal tissue through a minimal incision. It does not require a corneal flap and may involve a lower risk of post-treatment dryness for some patients.
SMILE is often considered for eligible patients with mild to higher levels of myopia, although suitability depends on individual eye measurements and prescription stability.
Considering LASIK, PRK, or SMILE?
Clearview Optical Calgary can help you understand your candidacy before you move forward with a surgical consultation.
For many candidates with stable prescriptions and healthy corneas, laser surgery can significantly reduce or remove daily dependence on glasses and contact lenses.
ICL and Lens-Based Myopia Correction Options
Laser surgery is not suitable for everyone. Patients with high myopia, thin corneas, or specific corneal conditions may be better served by lens-based procedures. These options correct the refractive error by adding or replacing a lens rather than reshaping the cornea.
ICL for High Myopia
An implantable collamer lens, often called ICL, is a soft lens placed inside the eye behind the iris and in front of the natural lens. Because no corneal tissue is removed, ICL can be an option for patients with high prescriptions or thin corneas.
ICL is often considered for myopia levels beyond what laser procedures can safely correct. It is usually more expensive than LASIK and is typically not covered by provincial health plans.
Refractive Lens Exchange for Severe Nearsightedness
Refractive lens exchange replaces the eye’s natural lens with an artificial intraocular lens. The procedure is similar to cataract surgery and may be considered for patients over 40 or for people with very high myopia.
Because the natural lens is removed, the eye loses its natural focusing flexibility. This makes careful lens selection and expectation-setting especially important.
Orthokeratology and Myopia Control in Calgary
Orthokeratology, often called ortho-k, does not permanently change the eye. Instead, it uses specially designed rigid contact lenses worn overnight to gently reshape the cornea while you sleep.
When the lenses are removed in the morning, many patients can see clearly throughout the day without glasses or daytime contacts. The effect is temporary and gradually reverses if lens wear stops.
Ortho-k is especially relevant for children and teenagers because it may help slow myopia progression while the eyes are still developing. For families in Calgary, this can be an important option to discuss during a child’s eye exam or myopia control appointment.
Concerned About Your Child’s Nearsightedness?
Ask Clearview Optical Calgary about myopia control options, including ortho-k, prescription lenses, and monitoring plans for growing eyes.
What Is the Best Myopia Treatment Option?
| Option | Permanent Change? | Best For | Typical Recovery | High Myopia? |
|---|---|---|---|---|
| LASIK | Yes | Mild to moderate myopia with healthy corneas | 24 to 48 hours | Case by case |
| PRK | Yes | Thin corneas or active lifestyles | 1 to 3 weeks | Case by case |
| SMILE | Yes | Eligible patients concerned about flap creation | A few days | Case by case |
| ICL | Additive | High myopia or thin corneas | A few days | Often |
| RLE | Yes | Patients over 40 or very high myopia | 1 to 2 weeks | Often |
| Ortho-K | No | Children, teens, and mild to moderate myopia | Ongoing use | Limited |
What to Expect From a Myopia Consultation in Calgary
The path to long-term correction should start with a comprehensive assessment, not a rushed decision. At Clearview Optical Calgary, a proper myopia consultation may include refraction testing, dry eye screening, retinal evaluation, prescription history review, and a discussion about whether surgical or non-surgical correction options make sense for your eyes.
Good questions to ask include:
- Has my prescription been stable for at least one to two years?
- Is my cornea thick and healthy enough for laser correction?
- Do I have dry eye or other conditions that could affect healing?
- What are realistic outcomes for my specific prescription?
- Which option offers the best balance of safety, results, recovery time, and cost?
No reputable provider should recommend a procedure before evaluating your eye health, prescription, corneal structure, and long-term risks. A strong consultation should explain both benefits and limitations.
The Bottom Line
Permanent and long-term myopia correction options are well-established, but the best choice depends on your prescription, eye health, age, lifestyle, and expectations. LASIK, PRK, SMILE, ICL, refractive lens exchange, and orthokeratology all serve different needs.
The most important step is not choosing the most popular treatment. It is getting a detailed assessment with an optometrist who can explain what is realistic for your eyes, your prescription, and your long-term vision goals.
