ICL (Implantable Contact Lens)

Vision correction without corneal abrasion

Vision correction without corneal abrasion

ICL is a refractive procedure where a lens is implanted in the eye to restore your vision. ICL is an abbreviation of “Implantable Contact Lens” and is also called phakic IOL surgery.
The lens is inserted the eye, placed between the iris and the natural lens. This means that the lens cannot be seen from the outside.

Since the refractive procedure does not involve any corneal abrasion, this means that the ICL provides a high quality of vision, no dry eye, and fewer halos and glares at night compared to conventional refractive surgery. The ICL lens provides a long-term solution with stable vision.

The Benefits of ICL

  • Technologically Advanced Lens Material

    Technologically Advanced Lens Material
    Unlike other lenses, the ICL is made from Collamer, a technologically advanced lens material exclusive to STAAR Surgical. Because of the collagen in Collamer, it is biocompatible with the eye (not seen as a foreign object to the body) and provides exceptional quality of vision. The lens rests in position while accurately correcting vision.
  • Designed to be Permanent, Yet is Removable

    Designed to be Permanent, Yet is Removable
    One of the most common concerns people have about laser-based correction is that the procedure permanently changes the shape of their eye by removing corneal tissue. An advantage of the ICL is that it can permanently correct your vision, yet no natural tissue is removed. If for the unlikely event you need or wish to remove your ICLs in the future, your doctor can accommodate you.
  • A Simple Procedure with Quick Recovery

    A Simple Procedure with Quick Recovery
    ICL is inserted in the eye with a special instrument. Eye drops are used so you will hardly feel any pain. Since the lens is inserted through a small 3 mm incision, your recovery will be fast. The incision will heal naturally so no sutures are necessary.
  • No Corneal Abrasion & a Large Optical Zone

    No Corneal Abrasion & a Large Optical Zone
    Since the ICL procedure does not abrade the cornea the corneal shape will remain the almost the same.
    Also, with its large optical zone, you will have less halos and glares at night compared to other laser-based procedures.
  • Treatment Flexibility for the Future

    Treatment Flexibility for the Future
    Your vision changes as you grow older and eventually almost everyone will need cataract surgery. Because ICL preserves the structure of the eye, the lens can be removed and replaced if your vision changes substantially, or if you have another procedure at any time.

The ICL procedure

  • 01
    Eye Drops Administered & Small incisionWhen you arrive for your procedure your doctor will administer eye drops to dilate your pupils as well as anesthetize your eyes. To prepare for the implant your doctor will create one small opening at the base of your cornea to insert the lens. The procedure is painless because of the numbing medication
  • 02
    Lens Insertion & PositioningThe lens can be folded and inserted through the small incision your doctor has made.
  • 03
    AdjustmentOnce the lens is inserted the doctor will make any necessary adjustments to ensure proper positioning in the eye.
  • 04

You will need someone to drive you home, your doctor will tell you when your vision allows driving.

ICL schedule

  1. Eye exam to see if your eye fits the ICL procedure. Before you schedule your ICL procedure, our clinic will perform a series of standard tests to measure your eye’s unique characteristics for the procedure (60-90 minutes, approximately 3000 yen).
  2. Before your pre-op eye exam, you cannot wear soft contact lenses for 1 week (in case of hard contact lenses this is 3 weeks).
  3. Pre-op eye exam. This will take approximately 2 hours. Eye drops will be administered to dilate your pupils. You will not be able to drive home by yourself, it might be difficult to see close by afterwards, and lights might feel bright for 2 to 3 days. We ask you to pre-pay your lens fee at the time of this examination.
  4. We might ask you to come in for an additional eye exam one week afterwards,
  5. Depending on the lens it takes 1 day to 8 weeks for the lens to arrive.
  6. Please use antibacterial eye drops starting from 3 days before the procedure.
  7. The procedure itself takes about 20 minutes, but your time in the clinic will be roughly 2 hours. At this time, you will be asked to pay the remaining fee
  8. A follow up exam will be done in the morning after your procedure (sometimes you might have to come in on the following day too).
  9. You should also return to the clinic for regular check-ups at 1 week, 1 month, 3 months, 6 months and every year after the procedure.

Safety information for the ICL shortly after the procedure

  • Your vision

    Change of vision: At 1 week after the procedure your vision might change as a result of inflammation.

  • Glare and halos, ring of light

    At night or in dark places you might lights as bright. This normally decreases, but please let us know if this persists.

  • Normal occurrences

    It is possible that you have a foreign-body sensation in your eye, there might be some blood left in the eye, or your vision might be hazy. This will normally improve with time.

Precautions after the procedure

For a certain period after the procedure, you will need to limit some daily activities as instructed by your doctor and nurse. Please follow their directions concerning:

  • Bathing/hair
    face washing
  • Make-up
    eye make up
  • Drinking
  • Driving
  • Sports
  • Heavy work


  • Are there any limitations on doing this procedure?
    Depending on the shape of your eye, eye diseases, general diseases, you might not be an ideal candidate for this procedure. A medical specialist will perform a series of exams to check the shape and health of your eye and will check your general health. It is important to stop wearing contact lenses for a certain time (especially hard contact lenses). Those who are pregnant or nursing do not have a stable eye vision and should not do refractive surgery.
  • Is the procedure painful?
    You will be administered anesthetic eye drops to minimize any discomfort and pain.
  • Will others notice the lenses in my eye?
    Since the lens is placed behind the iris, it is not possible to see the lens.
  • What are halos and glare?
    Bright circles around sources of light at night are called halos. Glare occurs in your vision when light enters your eye and actually obstructs your vision. These vision disruptions may occur for a certain period depending on the person. It is normal that these symptoms disappear after a few months.
  • Is this procedure covered by public health insurance?
    This is not covered by public health insurance, but please ask your private insurance if phakic IOLs receive any reimbursement.
  • Will this procedure treat presbyopia?
    After turning forty, people tend to gradually lose the ability to focus on nearby objects, and this is called presbyopia. The EVO Vison ICL procedure corrects myopia and astigmatism, but not presbyopia. As any other patient, you might need reading glasses.
