Implantable Collamer® Lens (ICL)
What is ICL surgery?
An Implantable Collamer Lens (ICL) is a micro-lens that works with your eye’s natural anatomy to deliver sharp, high-definition vision. It is an ideal solution for high prescriptions or thin corneas, especially for those who aren't candidates for LASIK. The procedure takes only minutes, and the lens can be safely removed or upgraded if your vision changes down the road.
Implantable Collamer® lenses are designed to provide premium visual outcomes for patients with high myopia (nearsightedness) or hyperopia (farsightedness). These artificial lenses are made from a soft, pliable material, which is a biocompatible collagen polymer that also offers UV protection.
Are there different types of ICL procedures?
Yes. The standard Implantable Collamer® Lens procedure corrects myopia (nearsightedness), while the Hyperopic ICL procedure is an alternative designed to treat hyperopia (farsightedness). Read more about the Hyperopic ICL procedure below.

The procedure is the same as a myopic implantable Collamer® lens procedure, but with the added step of having to undergo a short procedure beforehand. The first step is to undergo a laser peripheral iridotomy (LPI), one to four weeks prior to your lens implantation.
During the LPI procedure, the surgeon will create tiny openings in the outer edge of your iris, which will allow your eye to maintain its pressure after your new lens has been placed. After the LPI, you will be required to put drops in for four days. The healing period for the LPI is relatively quick so you will have been booked for your lens implantation soon after.
After this, you will be ready for your lens implantation, which follows the same steps as the myopic implantable Collamer® lens procedure below.
Our clinical team will assess your vision and help determine the option best suited to your eyes.
Benefits of ICL

"Thank you to the entire team for my ICL surgery. I’m currently two weeks post -op and everything is going well. My vision is even better than 20/20. I highly recommend this surgery to all suitable candidates. Thank you Michel at the Laval Clinic."
- Rishsy Petion
"I did my ICL surgery, and life has been so incredible since. It was one of the best decisions I made in my life! It's been so great to say goodbye to the glasses I wore for 20 years. [...] Everyone was super patient and professional! Highly recommend!"
- Claire Nie
"I got the ICL surgery to fix my vision (-9.5 both eyes) and it's almost perfect. [...] My vision's great, but I'd be fully aware that this isn't a perfect operation. For me, it's below perfect natural vision but above glasses and contacts."
- Brian Pho
What to expect during ICL surgery
Lens implantation is quick and straightforward, taking just 10 to 15 minutes per eye.
Your surgeon will apply eye drops to dilate and numb your eyes. You may notice temporary light sensitivity or mild blurriness for a few hours afterward — this is completely normal.
The surgeon will create a small incision at the base of the cornea. This is where the lens will be inserted behind the iris, the coloured part of the eye. It will be positioned directly in front of the natural crystalline lens. The lens will then be properly inserted and positioned.
Most patients will be able to return to their day-to-day activities in the 24 hours after surgery. Please note that you cannot be allowed to drive home following your procedure and must arrange for transportation ahead of time.
A check-up will be scheduled within 24 hours, and regular follow-up visits are required during your first year to ensure your eyes are healing properly.
ICL safety
Implantable lenses have been on the market for decades, helping a multitude of people achieve clear vision. This type of technology helps patients meet their individual vision needs while adhering to strict safety guidelines.

If you have high myopia or hyperopia and aren’t eligible for laser vision correction, ICL could be the best option to help you achieve clear, lasting vision.
FAQs
What is ICL?
An Implantable Collamer Lens (ICL) is a small, biocompatible lens surgically placed between the iris and natural lens to correct nearsightedness (myopia) and astigmatism. The minimally invasive procedure takes 20–30 minutes per eye, requires no removal of corneal tissue, and provides sharp, clear vision.
How much does ICL cost?
The cost varies depending on your specific prescription and clinic location. Flexible monthly financing plans are available. Book a free consultation to receive a personalized quote.
How long is ICL surgery?
The procedure takes about 20–30 minutes per eye, with total clinic time under two hours for preparation and recovery. No stitches are required, and many patients see visual improvements within 24 hours.
How does ICL compare to LASIK?
LASIK is the most common laser vision correction option and suits many patients. ICL is a premium, removable alternative that preserves the cornea, making it ideal for individuals with high myopia, thin corneas, or chronic dry eyes.
Can ICL treat astigmatism?
Yes. ICL corrects both myopia and astigmatism simultaneously in a single procedure, making it an excellent option for patients who may not qualify for LASIK.
Is ICL safe?
Yes. ICL is Health Canada-approved and performed worldwide. The highly biocompatible Collamer material minimizes risks of rejection or inflammation. Potential risks will be fully detailed during your consultation.
Is ICL painful?
No. Numbing anesthetic eye drops are applied before surgery, so you will feel little to no pain, though mild pressure may be noticed. Any temporary light sensitivity or minor discomfort usually resolves within 1–2 days.
Can ICL be removed?
Yes. The lens can be safely removed or replaced if your prescription changes or alternative treatments are preferred.
How long does ICL last?
ICL is designed to be permanent and stable indefinitely without degrading. It does not prevent natural, age-related vision changes (like presbyopia) that occur later in life.
What are the risks of ICL?
Potential side effects include temporary halos, glare, light sensitivity, mild inflammation, or elevated eye pressure. Serious complications are rare. Your surgeon will review all potential risks during your consultation.
Who qualifies for ICL surgery?
Ideal candidates are adults aged 21–45 with stable myopia (with or without astigmatism), adequate anterior chamber depth, and healthy endothelial cell counts. It is a premier choice for those ineligible for LASIK due to high prescriptions or thin corneas.
How long is ICL recovery?
Recovery is rapid. Most patients return to light activities within 1–2 days, with full recovery taking 1–4 weeks. You must use prescribed eye drops and avoid swimming and contact sports during recovery.
Does insurance cover ICL?
As an elective procedure, ICL is not covered by provincial health insurance plans. However, it may qualify for the Medical Expense Tax Credit or partial reimbursement through private extended healthcare. Financing options are available.
Can I get ICL if I have dry eyes?
Yes. Because ICL does not alter corneal tissue or disrupt surface nerves, it does not worsen dry eye symptoms, making it an ideal alternative for patients with dry eyes. A pre-operative evaluation will confirm eligibility.
Can I get ICL if I am not eligible for LASIK?
Yes. ICL is an established alternative for patients who are excluded from LASIK due to thin or irregular corneas, extreme myopia, or severe dry eyes. A consultation will confirm your eligibility.
Procedure availability varies by LASIK MD clinic and is subject to factors such as location, medical expertise, and patient eligibility as determined by a physician. Please contact your local clinic to confirm the availability of a specific procedure.
