EVO ICL™

EVO Implantable Collamer Lens


The Implantable Collamer® Lens, or ICL™, was designed to be placed within an eye, overlying the eye’s natural lens, to correct nearsightedness, farsightedness, and astigmatism. No corneal tissue is removed, making this procedure an option for patients with thin or irregular corneas who would otherwise not qualify for laser vision correction.

ICL™s are made from Collamer®, a proprietary material containing collagen—a naturally occurring protein in your body. This makes them biocompatible with the eye to work in harmony with the natural eye. They are removable if necessary, but this is very rarely needed. Other benefits of EVO ICL™ include an immediate visual improvement with a quick recovery and UV protection.

Implanting the EVO ICL™ is performed as an outpatient procedure. Topical drops are used to anesthetize the eye, so no injection is necessary. In rare cases, patients are mildly sedated with oral medication, but only if it is necessary for the patient’s comfort. The whole procedure takes approximately 10-15 minutes for each eye.

The EVO ICL™ is inserted through a 2.7mm incision and is carefully positioned inside the eye, in front of the eye’s natural lens. The EVO ICL™ becomes the eye’s third focusing lens (the cornea and the natural lens being the other two lenses), similar to wearing a contact lens.

Dr. Senekal uses the new generation STAAR EVO ICL™, which requires no peripheral iridotomy (drainage hole made in the iris by laser) due to pre-existing drainage apertures or small openings in the EVO ICL™ called Aquaports. The surgery is usually completed without sutures since the incision is designed to be self-sealing. 

For some patients with very high refractive errors, a combined procedure might be necessary to correct the full refractive error, such as an EVO ICL™ implantation followed by LASIK or SMILE.

ICL™ surgery is referred to as additive vision correction since it does not require any removal of corneal tissue, and the inserted lenses are biocompatible. This makes recovery after an ICL™ procedure quick and easy. 

Most patients achieve driving standard or better vision within two days of surgery. Mild discomfort is normal, and eyes may be light-sensitive in the first few days after surgery, requiring protection from the sun when you go out. Dr. Senekal will prescribe an antibiotic and anti-inflammatory eye drops for the first week after surgery. 

Eye rubbing should be avoided, and swimming is not recommended for a few weeks, but there are few other restrictions on activity after this procedure.

If you are between 21 and 60 and have had a stable eye prescription for a year, you may be a good candidate for the EVO ICL™ procedure. Additionally, if you have dry eye syndrome, or a highly irregular or thin cornea, you may consider this option with Dr. Senekal.

EVO ICL™ can be inserted to correct the hyperopia, myopia, or astigmatism in pseudophakic patients, or patients who previously underwent cataract surgery. Pseudophakia is the Latin word for “false lens.” During cataract surgery, patients have their natural lenses replaced with artificial lenses. 

Some patients may be dissatisfied with the visual outcome after the surgery and seek greater independence from eyeglasses or contact lenses. ICL™ could be a safe and stable add-on option to enhance visual acuity for pseudophakic patients.  

Patients who underwent a corneal transplant or graft and are left with significant visual impairment due to astigmatism or myopia can often be visually rehabilitated by implanting an ICL™.

The following refractive errors can be corrected by an EVO ICL™ procedure (exceptions may apply):

Myopia (nearsightedness): From -2.0 up to -20.0 Diopters
Hypermetropia (Farsightedness): From +0.5 up to +10.0 Diopters
Astigmatism: up to 6.00 Diopters
