ICL surgery may seem like a new-and-unfamiliar procedure to many, but in fact ICL predates LASIK. The first ICL surgery was performed in 1986, and since then it has been employed in procedures around the world. In addition, ICL clinical trials were held in Japan starting in 2003, ultimately leading to approval by the Ministry of Health, Labor, and Welfare in 2010. The first ICL patients exhibited postoperative side effects such as cataracts and glaucoma. These side effects were resolved, however, with the EVO Visian ICL (employing a tiny hole of 0.36 mm in the center of the lens for circulation of the aqueous humor) developed by Professor Kimiya Shimizu (currently Director of Sanno Clinic Eye Center) of Kitasato University. After this change, the number of patients opting for the operation rose dramatically, at which time the ICL became popularly known as the “implantable contact lens.”
Are you familiar with the globally popular ICL surgery? While retaining the eye’s crystalline lens, ICL surgery—designed to correct myopia and astigmatism—involves insertion of a prosthetic lens into the eye. The ICL is regarded as a “implantable contact lens” due to the fact that it remains in the eye, maintenance-free, indefinitely. Our clinic utilizes an extremely safe, cutting edge EVO Visian ICL model with a central hole. The procedure performed fixes the prosthetic lens between the iris (pupil) and the crystalline lens in the posterior chamber of the eye.
The ICL Technique
ICL surgery does not require creating a corneal flap and corneal tissue removal. This surgery instead consists of placing a prosthetic lens between the iris and the crystalline lens while retaining the eye’s natural crystalline lens focus-adjusting mechanism.
Advanced “EVO Visian ICL”
We chose the EVO Visian ICL with a central hole because it is a cutting-edge lens developed to dramatically lower the risks associated with cataract surgery. The ICL used in conventional posterior chamber Phakic IOL necessitated the creation of a small hole in the iris before or during the surgery to avoid any increased pressure in the eye caused by flow of the aqueous humor. At our clinic, we provide the EVO Visian ICL, the latest technological advancement, which features a tiny hole in the center of the lens. Complications as well as recovery time for patients. In our clinic, we adopted the advanced EVO Visian ICL, which was researched and developed to eliminate the need to create a hole in the iris. This maintains the flow of the aqueous humor well and greatly reduces the risk of complications and the burden on the patient's eye. *Approved by the Ministry of Health, Labor, and Welfare as of March 3, 2014 (Medical device authorization number: 22600BZX00085000)
Impact of the lens on the human body
Because these lenses are placed in the eye for a very long time, it is critical to verify that they are safe for use in the human body over the long term.
The ICL used at our clinic is made of Collamer®, a new material that scores high marks for its superior biocompatibility. Sales of this lens were launched in Europe in 1997, and since then they have been used in over 1 million eyes in over 75 countries around the world. The product boasts an impressive track record of more than 20 years, earning an excellent reputation for reliability.
Optical properties: a built-in anti-reflective layer A softly-contoured refractive index running from the surface to the inner center of the lens dramatically reduces glare. Because Collamer® is made of hydrophilic materials, it is characterized by less reflection and minimal higher-order aberrations.
Lens Shape: Lens Design Evolution V1: Proto type model ICL (1990) V2: Positioning marks added (1994) V3: Optic diameter changed (1996) V4: Vault changed, new optical design developed (1999) V4c (EVO): Lens with central hole earns CE marking（2011） V5 (EVO+): Optic diameter further extended (2016)
New material Collamer®️ The lens itself carries a negative charge due to its collagen content, repelling negatively charged particles such as proteins. Collamer® demonstrates superior QOV (Quality of Vision) and biocompatibility, rendering it stable in the eye over the long term.
Sharp vision and vivid color recognition
Because this procedure corrects myopia of the eye’s natural lens without re-shaping the cornea, there are no additional aberrations affecting post-surgery vision. The result is clearer colors as well as “high definition” depth and three-dimensionality unlike anything the patient has experienced.
Steps of the ICL Procedure (approximately ten minutes required for both eyes)
STEP 1 Anesthesia and surgery on right eye
An anesthetic eye drop is applied, followed by an incision of about 3 millimeters in the cornea, in order to insert the lens (ICL). Using an injector, the ICL, which is folded long and thin, is inserted into the incision. Note: Because the incision is so small (3 mm), stitches are not required. Though antibacterial eye drops should be used for some time after surgery, the incision will heal relatively quickly on its own.
STEP 2 ICL implanted
The folded ICL will slowly open on its own in the posterior chamber of the eye.
STEP 3 Lens fixed in place
The open lens is fixed in place on both sides in the ciliary sulcus.
STEP 4 Anesthesia and surgery on left eye—post-operative examination
The same procedure is repeated for the other eye. The operation is completed for both eyes in just ten minutes. Afterward, a rest period of approximately 20-30 minutes is required, followed by a medical examination, after which the patient is free to go.
Flow to ICL surgery
①First visit reservation using the online booking form
Please select your desired date and time.
②Receive an email confirmation of first appointment reservation
③First visit examination with limited wearing of contact lens
Do not wear soft contact lenses for 3 days before your examination, and stop wearing hard- or continuous wear contact lenses for 2 weeks before your examination
④Initial examination indication examination
In order to check if you are eligible for surgery, we will examine your eyes and also check for eye diseases. You will not be able to drive a car after the eye examination (the pupil is dilatation with eye drops and then examined). Ask us any questions or concerns you may have with our Ophthalmologists who are certified by the Japanese Ophthalmologist Society or one-on-one counseling.
⑤Re-examination to determine ICL lens prescription
It is an important examination to ensure visual acuity after surgery. Please continue to stop wearing contact lenses before taking this re-examination.
⑥Antibiotic eye drops for surgery
Please use eye drops from 3 days before surgery. It is important to use eye drops in order to prevent infections.
⑦On the day of surgery
Contact lenses can be worn until the day before surgery, but please visit us wearing glases on the surgery day. You can go home alone without attendants, but you can not see clearly after the surgery, and you will sense as having some kind of foreign matter in your eyes and have teary eyes, so please go home early and rest your eyes. Eye drops are very important on the day of the surgery, so use them carefully.
⑧Examination of the next day after surgery
When getting up in the morning, there is almost no sense of foreign matter, and your vision will be quite clear. Please start your eye drops as soon as you get up. Please visit us at the reservation time.

Advantages & Disadvantages
ICL accommodates even severe myopia (nearsightedness), hyperopia (farsightedness), and astigmatism
For LASIK surgery, the Japanese Ophthalmological Society Refractive Surgery Guidelines go up to the 10D level Literature 8. Because ICL surgery involves implantation of a wide range of prescriptions of the ICL, it corrects even severe nearsightedness and farsightedness as well as astigmatism.
Highly accurate correction and long-term stability of vision
ICL provides the same level of accuracy as a conventional soft contact lens. The patient will enjoy stable, quality vision for the long term, without the risk of visual regression.
Freedom from post-operative side effects or problems with night vision
A smaller corneal incision (approximately 3 mm) reduces the risk of postoperative side effects such as dry eye. In addition, ICL causes less problems with night vision such as halos and glare caused by higher-order aberrations (distortion of corneal surface) associated with LASIK surgery Literature 4-6 are further ameliorated by the new EVO+ Visian ICL model (with an enlarged optical zone).
Lens is removable in the unlikely event of problems
In the absence of particular problems, the ICL implant is considered semi-permanent. However, should any problems arise following the surgery, the ICL can be removed and the patient’s vision restored to its condition prior to the surgery (provided the patient continues to wear glasses or contact lenses to correct their vision).
Cost of surgery is relatively high
Because the ICL is ordered to exactly fit your eye, its cost is higher than other corrective eye surgeries. Please note that ICL orders cannot be refunded.
Waiting times for surgeries
Your surgery can be performed as early as the week following your examination, depending the arrival of the lens. In some cases if you have a special prescription, you main have to wait for a little over 2 months.
Halo, glare, and circle of light
After the operation, you may experience a mild halo or glare or circle of light. This should virtually disappear within a month after the operation.
The importance of pre and post-operative care
With ICL surgery, pre and post-operative care is critical due to the fact that the prosthetic lens is placed in the eye. Though the instance of infection associated with an ICL procedure is extremely rare (approximately one in 6,000 cases), it is important to follow instructions on the use of eye drops and to note any other precautions indicated.
Comprehensive pre-surgical and post-surgical care system
Preliminary screening and examination by a Japanese Ophthalmological Society-certified doctor
Each patient is first given a comprehensive screening to assess refraction and visual acuity as well as corneal shape, anterior chamber depth, fundus of the eye, etc. These results are then examined by an experienced Japanese Ophthalmological Society-certified doctor, who will determine whether the patient is a candidate for ICL, or if not, which procedure would be optimal.
Based on the results of screening procedures and an examination by a physician, a specialist counselor will meet one-to-one with the patient to answer any questions and help to alleviate any doubts or concerns.
Thorough pre-surgical medical examination
A more detailed examination follows to decide on the patient’s postoperative visual acuity, in which the size and prescription of the ICL is determined. The patient will be informed of the date scheduled for their operation once the ICL delivery date is confirmed.
The surgical procedure
Surgery takes approximately 10 minutes for both eyes. Following the procedure, the patient rests for 20-30 minutes, after which time the patient is given an exam to assess refraction and intraocular pressure. Provided no issues arise, the patient is then free to leave.
Long-term follow-up care
Our clinic offers a comprehensive follow-up care program, which includes regular post-surgical examinations, to help ensure the patient’s vision is stable for the long-term.
