Common Questions

EVO Viva is an implantable Collamer lens that works with the natural structures of your eye to provide clearer vision at all distances—near to far. EVO Viva is inserted behind the iris (the colored part of the eye) and in front of the natural crystalline lens in order to improve vision.

EVO Viva is intended to remain in place without maintenance. The lens can be removed by your eye care professional, if needed, in the future. If your physician removes the lens, you will lose the benefit of your vision correction.

The material is called Collamer®, a collagen co-polymer that contains a small amount of purified collagen, which is proprietary to STAAR Surgical. The remainder is made of a similar material to that found in soft contact lenses. It is biocompatible (does not cause a reaction inside the eye) and stable. It also contains an ultraviolet light filter.

ICLs have been improving people’s vision around the world for over 25 years and have been implanted in over 1,000,000 eyes worldwide.

No. EVO Viva is positioned behind the iris (the colored part of the eye), where it is not visible to both you and others. Only your eye care practitioner will be able to tell that vision correction has taken place.

EVO Viva is not typically noticeable after it is implanted. It does not attach to any structures within the eye and does not move around once in place.

The EVO Viva surgery is performed on an outpatient basis, which means that the patient has surgery and can go home the same day. The procedure itself usually takes 20–30 minutes or less. Topical, or local, anesthetic, is administered, and there is typically little discomfort during or after surgery. Some eye drops or medication may be prescribed, and a visit with your eye care professional is usually scheduled the day after surgery. The patient will need someone to drive them home on the day of surgery.

Follow all of your eye care professional’s instructions before and after implantation of EVO Viva. Take any prescribed medication and schedule all recommended follow-up visits with your eye care professional. Contact your eye care professional immediately if you should experience a problem.

Important Safety Information for EVO Viva ICL

Before considering EVO Viva ICL surgery you should have a complete eye examination and talk with your eye care professional about the EVO Viva ICL procedure, especially the potential benefits, risks, and complications. You should discuss the time needed for healing after surgery.

The EVO Viva ICL is designed for the correction/reduction of up to -20 diopters (D) of nearsightedness with or without presbyopia for patients who are 21 to 60 years of age; for the correction/reduction of up to +10 diopters (D) of farsightedness with or without presbyopia for patients who are 21 to 45 years of age; and for patients 21 years of age or older who have been treated with an intraocular lens. Implantation of the EVO Viva ICL is a surgical procedure, and as such, carries potentially serious risks.

The following represent potential complications/adverse events: additional surgeries, cataract formation, transient or persistent loss of best-corrected vision, raised pressure inside the eye, loss of cells on the innermost surface of the cornea, conjunctival irritation, corneal swelling, conjunctival irritation, endophthalmitis (total eye infection), significant glare and/or halos around lights, hyphema (blood in the eye), hypopyon (pus in the eye), eye infection, EVO Viva ICL dislocation, macular edema, non-reactive pupil, pupillary block glaucoma, severe inflammation of the eye, iritis, uveitis, vitreous loss, and corneal transplant.
