This provider locator tool is being provided by STAAR Surgical Company (“STAAR”) solely to assist users in locating a provider who has experience with the EVO ICL family of lenses, as explained further here. Specifically, the sole criteria for inclusion in the locator is whether a provider is certified by STAAR to implant EVO ICL lenses. Users may search the locator by zip code, state, or current location. Two types of sorting functionality is available within the locator. Users are able to sort the results via distance, or by the frequency with which a healthcare provider has recently used EVO ICL lenses (e.g., within the past 12 months). Irrespective of the sorting method selected, all providers are shown in the results within the queried geographic location. The listed order of providers under any sorting method, including the initial presentation of providers in a geographic location, is based on a variety of factors, including whether the provider maintains consumer-facing information about EVO ICL lenses on its website, the breadth and quality of such information, whether it has demonstrated a commitment to training staff and offering the EVO ICL as a refractive procedure option to qualified patients, and how frequently the provider has performed procedures using the EVO ICL over the past year.
Notwithstanding the above, this provider locator tool should not be construed in any way as an endorsement or recommendation by STAAR as to the qualifications of any provider listed in this tool or the quality of medical care they can provide. STAAR makes no guarantees that using a provider from this list will result in your desired outcome. It is wholly and solely your responsibility to assess the qualifications of a potential provider. STAAR recommends that you meet and discuss the benefits and risks of the EVO ICL lens, and the procedure to implant the EVO ICL lens with the potential provider.
STAAR hereby disclaims any and all liability arising from your use of and/or reliance on the information contained in this provider locator tool.
Important Safety Information
The EVO Visian ICL Lens is intended for the correction of moderate to high nearsightedness. EVO Visian ICL and EVO Visian TICL surgery is intended to safely and effectively correct nearsightedness between -3.0 D to -15.0 D, the reduction in nearsightedness up to -20.0 D and treatment of astigmatism from 1.0 D to 4.0 D. If you have nearsightedness within these ranges, EVO Visian ICL surgery may improve your distance vision without eyeglasses or contact lenses. Because the EVO Visian ICL corrects for distance vision, it does not eliminate the need for reading glasses, you may require them at some point, even if you have never worn them before.
Implantation of the EVO Visian ICL is a surgical procedure, and as such, carries potentially serious risks. Please discuss the risks with your eye care professional. Complications, although rare, may include need for additional surgical procedures, inflammation, loss of cells from the back surface of the cornea, increase in eye pressure, and cataracts.
You should NOT have EVO Visian ICL surgery if:
- Your doctor determines that the shape of your eye is not an appropriate fit for the EVO Visian ICL
- You are pregnant or nursing
- You have moderate to severe damage to the optic nerve caused by increased pressure (glaucoma)
- You do not meet the minimum endothelial cell density for your age at the time of implantation as determined by your eye doctor
- Your vision is not stable as determined by your eye doctor
Before considering EVO Visian ICL surgery you should have a complete eye examination and talk with your eye care professional about EVO Visian ICL surgery, especially the potential benefits, risks, and complications. You should discuss the time needed for healing after surgery. For additional information with potential benefits, risks and complications please visit DiscoverICL.com.
