ICL (Implantable Collamer Lenses)

ICLs are like implantable contact lenses that improve visual acuity, or eyesight, for people who have Myopia, Hypermetropia & /Or Astigmatism.

Although this is a rarely performed procedure, many adults with stable refractive errors can benefit from ICLs, especially if they are not good candidates for LASIK for certain reasons like thin cornea, high Glass power etc. Clinical studies have also shown this implantable lens option is a safe, effective procedure to improve vision.

The EVO Visian ICL surgery is like LASIK or other refractive surgeries, requires a few more steps in the weeks leading up to it, and takes about 5 minutes longer in the operating room. it costs a bit more than a procedure like LASIK.

EVO Visian Implantable Collamer Lenses (ICLs) are like permanent contact lenses. These miniscule devices improve vision for people with myopia or nearsightedness &/or Astigmatism.


EVO Visian ICLs can be a good option for many people who have myopia &/or astigmatism. These small devices are a type of toric lens, which is an artificial lens implanted in the eye to improve vision.

The EVO Visian ICL specifically is implanted behind the iris, but in front of the natural lens. Adding an additional lens helps focus light without removing any tissue from your cornea, as in LASIK surgery. These lenses work best in people who:

Have a stable refractive error, or no change of more than 0.5 diopters in the past year.

Have myopia ranging from -3.0 to -15.0 diopters, with 3.0 diopters or less of astigmatism.

Have myopia up to -18.0 diopters with astigmatism up to -6.0 diopters, for those using the newer, high myopia lenses.

Are between 21 and 40 years old.

Are not good candidates for LASIK due to personal preference or cornea thickness.

EVO Visian ICL offers an alternative for people with myopia or astigmatism. You may be a poor candidate for LASIK but a good ICL candidate if:

You have high myopia or naturally thin corneas.

You have had a previous refractive surgery.

You have chronic dry eye, which can get worse from LASIK surgery.

You want a replaceable option if your prescription changes a lot, or a new, improved form of EVO Visian ICL is developed.

While fewer people have undergone EVO Visian ICL surgery since LASIK is much more popular, the devices have a high success rate for improving vision.

Surgical Procedure :

Like any vision surgery, the EVO Visian ICL surgery requires a complete eye exam and consultation with an optometrist or ophthalmologist. This ensures your eyes are healthy, you have no underlying conditions that would complicate the procedure, and your refractive error is within the ICL specifications.

You can also discuss any medications you take that are not involved directly in your vision. Underlying health conditions and some medications can impact your overall healing time.

Your eye surgeon will ask you to stop wearing contact lenses for One to Two weeks prior to the exam. Even soft contact lenses have an impact on the shape of your cornea and how much oxygen your eyes receive. Giving your eyes time to reshape ensures your eye doctor gets a stable measurement of their shape.

Arrange transportation to and from the procedure. While the EVO Visian ICL surgery is an outpatient procedure, meaning you will go home the same day as the operation, you will not be able to drive yourself. Your doctor will tell you when your vision is good enough to drive again.

what to expect:

Day of surgery: You will receive numbing eye drops. Then, you’ll lie down so your surgeon can place devices on your eye to keep your eyelids open. A small incision will be made in your cornea, which is the clear material at the front of your eye. Finally, your eye surgeon will implant the EVO Visian ICL.

The entire operation takes between 10 to 15 minutes. You will receive medicated eye drops, and your surgeon may put a patch over your eye to protect it for 3 hours.

Your eye doctor will examine your eyes the day after the procedure. This helps to prevent any infection or damage to the eye.

Costs, Risks & Recovery Surgery:

ICLs are considered cosmetic, and they are not going to be covered by your vision insurance, so the cost is out of pocket.

As with any surgery, there are potential side effects and risks associated with ICL surgery. Clinical studies found that lens rotation was the most significant side effect to impact vision, but it was very rare. There is also a small, but increased, risk of:

Infection (endophthalmitis).

Undercorrection or overcorrection that requires another operation to correct the issue.

Halos, glares, or double vision.

Macular edema.

Damage to the cornea.

Developing cataracts.

Increased eye pressure, leading to glaucoma.

Iris prolapse.

Needing a second eye surgery to remove the lens.

If you develop high ocular pressure, you may require a surgical procedure to reduce that pressure.

In the rare case that your vision is not corrected to 20/40 or better, you may need glasses or contact lenses. It is possible to undergo a refractive laser surgery like LASIK to improve your vision further. Talk to your eye surgeon about this option.

EVO Visian ICLs & Future Cataract

EVO Visian ICL can be safely taken out and replaced with a new lens after a few years when patient develops cataract. It is just like Routine Cataract Surgery.
