Looking for an alternative to laser vision correction? Nearsighted patients can benefit from surgically implanted lenses called phakic IOLs (intraocular lenses). These lens implants, also referred to as implantable collamer lenses, can correct moderate to severe myopia, allowing patients whose prescription falls outside the LASIK range to experience corrected vision and enjoy visual freedom. Unlike LASIK or PRK, the phakic IOL implant does not change the shape of the eye. Although intended to remain in the eye permanently, the lens can be removed if necessary.

Phakic intraocular lens implants are similar to the intraocular lenses used in cataract surgery. However, in this type of lens implant surgery, the eye’s natural lens remains in place and the phakic IOL is inserted either on the iris or immediately behind the iris. This eye lens implant corrects vision by acting like glasses or contacts within the eye.

The surgical implant procedure is performed on an outpatient basis and takes about 20 minutes. After anesthetic drops are used to numb the eye, a tiny incision is made to create an opening for the insertion of the implant lens. Since the incision is self-sealing, the surgery is usually completed without stitches.

Following the procedure, improved vision is often observed immediately. However, patients may experience a mild scratchiness immediately following surgery and should rest at home with their eyes closed as much as possible for the rest of the day. Most patients are able to return to normal activity within a few days after lens implant surgery.


STAAR® EVO – Evolution in Visual Freedom – is a breakthrough, FDA approved Implantable Collamer Lens procedure for myopia and astigmatism designed to provide premium refractive outcomes while optimizing patient comfort. Made from Collamer® – a biocompatible material that works in harmony with the eye – EVO can treat a wide range of refractive errors.

Patients who want a flexible and biocompatible vision correction option, as well as many patients who are not candidates for laser vision correction, find that Visian EVO ICL is the right procedure for them.  In a survey, 99.4% of EVO patients have stated they would have the procedure again.

The lens, which is slightly smaller than a typical contact lens, is implanted in the eye during a 20 to 30 minute procedure.

Unlike laser vision correction surgeries that permanently change the shape of the cornea, the EVO Visian ICL procedure is additive, meaning that no corneal tissue is removed. The EVO lens has a small hole in its center allowing the flow of fluid to the front of the eye, therefore  preventing dry eye syndrome. Worldwide, more than two million EVO Visian lenses have been implanted. Ask us about the STAAR EVO Practice Champion Certification.
