EVO+ Visian ICL™ prevents blockage from any possible residue in the eye through a 360㎛ hole in the center of the lens. This also assists the flow of aqueous fluid. The improved aqueous flow greatly reduces the possibility of cataract caused by the contact between ICL and the natural lens of the eye.

Among many of the extensively detailed eye examinations, the UMB ultrasound biomicroscopic examination is by far the most important exam you must take before any ICL. Not only the anterior part of the iris but also the fine posterior part of the iris must be checked. EYEREUM, on deciding the accurate lens size, examines the space between the iris and the eye’s natural lens and also obligatorily checks the Angle-Closure, the adhesion of the iris, along with glaucoma.

Just as a T-shirt comes in S, M, L, XL sizes, so does the ICL. A thorough preliminary examination will determine which size is compatible for you. However as this method was designed for Westerners’ eyes, it sometimes brought about side effects to Asians. EYEREUM, focusing on this problem, presented <ICL calculation method suitable for Koreans> and was awarded ICL Global Expert from STAAR Surgical Inc., the maker of ICL..

• 01 Advantages

  • Unlike LASIK or LASEK, the cornea is intact /untouched, so the procedure can be reversed.
  • Vision correction is possible to those with thin corneas and weren’t eligible for LASIK or LASEK.
  • It can maintain a stable vision without myopia regression/degeneration.
  • The placement of the ICL makes the lens invisible to the patient and any observer.
  • There are no side effects like corneal flap detachment or keratoconus which are attainable from LASIK.
  • A sharper, clearer and more vivid vision can be obtained with less chance of night blurred vision or halo vision.
  • It is a simple procedure using topical anesthetic eye-drops.
  • The tiny incision reduces the risk of astigmatism.
  • The 3mm incision doesn’t require stitches /sutures and self-heals quickly.

• 02 Disadvantages

  • The ICL lens and other devices involved are all high-priced, leading to a costly surgery.
  • There is a rare chance of cataract if the lens is in contact with the eye’s natural lens and glaucoma if the aqueous fluid flow is blocked.
  • The frontal depth has to be more than 3.0mm.
  • Iiridotomy is required in some cases to prevent glaucoma.
  • Intraocular pressure management is needed after surgery.
  • Correction is only possible to a certain fixed point.
  • A high-degree of expertise is required, so the surgery should be carried out by a surgeon with great accumulated experience.
  • Those whose pupils become larger in the dark : Pupils control the amount of light that enters the eyes.
    Patients with large pupils may suffer permanent, debilitating visual aberrations such as starbursts and halos. They should consult with their specialist before undergoing any vision correction treatment.

• 01 Candidates for ICL

  • Excessive Myopia: When patients suffering from excessive myopia undergo any laser correction surgery, a large amount of corneal tissue has to be removed, which causes side effects. So implanting an intraocular lens is much safer and more stable.
  • Thin corneal thickness: Those with moderate myopia may have such a thin cornea that laser surgery isn’t advisable.
  • Corneal scarring or corneal disease: The ICL doesn’t damage the cornea tissues and is applicable to those ｗith corneal problems.
  • Extreme dry-eyes: As laser surgery can induce dry-eyes, those already suffering from dry-eyes need to consult their special beforehand.

• 02 Not a candidate for ICL

  • Those with a low degree of myopia of astigmatism can easily correct their vision through LASIK, and do not require ICL.
  • Those with glaucoma, cataract, or keratoconus, with a low corneal endothelial cell count, a shallow frontal depth, and other corneal lesions / iritis or iridolysis, / systemic diseases such as diabetes or high blood pressure.
