EVO & EVO TICL is designed for the correction of moderate to high near-sightedness (-0.5 to -18.0 dioptres (D)) and the reduction of near-sightedness in patients with up to -18 dioptres (D) of near-sightedness with less than or equal to 6.0 dioptres (D) of astigmatism. It is indicated for patients who are 21 to 60 years of age. In order to be sure that your surgeon will use a EVO with the most adequate power for your eye, your near-sightedness should be stable for at least a year before undergoing eye surgery. EVO surgery has been documented to safely and effectively correct near-sightedness between -0.5 dioptres (D) to -18.0 dioptres (D) and partially correct near-sightedness up to -18 dioptres in eyes with up to 6.0(D) of astigmatism. If you have near-sightedness within these ranges, EVO surgery may improve your distance vision without eyeglasses or contact lenses. EVO surgery does not eliminate the need for reading glasses, even if you have never worn them before. The EVO represents an alternative to other refractive surgeries including, laser assisted in situ keratomileusis (LASIK), photorefractive keratectomy (PRK), incisional surgeries, or other means to correct myopia such as contact lenses and eye glasses. EVO is not intended to correct any astigmatism you may have. Implantation of the EVO is a surgical procedure, and as such, carries potentially serious risks. Please discuss the risks with your eye care provider. The following represent potential complications/adverse events reported in conjunction with refractive surgery in general: conjunctival irritation, acute corneal swelling, persistent corneal swelling, endophthalmitis (total eye infection), significant glare and/or halos around lights, hyphaema (blood in the eye), hypopyon (pus in the eye), eye infection, EVO Visian ICL dislocation, macular oedema, non-reactive pupil, pupillary block glaucoma, severe inflammation of the eye, iritis, uveitis, vitreous loss and corneal transplant. Before considering EVO surgery you should have a complete eye examination and talk with your eye care professional about EVO surgery, especially the potential benefits, risks and complications. You should discuss the time needed for healing after surgery.
