Does the thought of putting a lens in your eye seem frightful and painful? Implantable Collamer Lens (ICL) surgery places a small lens in your eye to correct your vision. The procedure takes around 10 minutes for each eye, and it uses the same topical anesthesia that is administered for cataract surgery, which is currently very common in Japan.
ICL surgery has been performed in Japan for as long as LASIK surgery has. Both procedures were first performed by the director of the Sanno Eye Center, Dr. Kimiya Shimizu, who also developed the ICL KS-AquaPORT® lens that is now used in over 70 countries around the world. Dr. Shimizu is an internationally recognized surgeon with extensive experience in his fields.
ICL surgery was first performed in Japan in 1997, and since then there has not been one reported case of any resultant decline in visual acuity. ICL surgery is an extremely safe procedure.
After ICL surgery, your life will change from feeling like “I want to see clearly” to “I can see clearly!” *1
Although the lens implanted in your eye has a somewhat complex name of Implantable Collamer Lens (ICL), the post-operative care is quite simple and only requires regular eye checks; there is no need for daily maintenance such as washing the lens to keep it clean. The ICL does not feel uncomfortable or like there is some foreign object in the eye, and you cannot even see that it is in there. *2
Many professional athletes also use ICL, and so far there are no reports of the lens breaking or becoming dirty while in the eye. So you can use ICL semi-permanently, and be free of the hassle of disposable lenses.
The incisional wound is very small at only 3mm, so it does not cause dry eyes or feel unpleasant. *1,2
The ICL prescription range covers high myopia (near-sightedness) and hyperopia (far-sightedness) both of which cannot be treated by LASIK, and also astigmatism (blurred vision).
ICL surgery is a day-procedure that uses a relatively painless topical anesthesia*, and takes around 10 minutes for each eye (basically both eyes are done on the same day). You can see fairly clearly straight after the operation, and after several hours of rest your vision becomes even clearer; it is around 70% restored on the day of the operation, and you can go home the same day without needing your glasses or normal contact lenses. Your vision is 90% to 100% restored by the day after ICL surgery, so you can do desk work and other general tasks.
The incisional wound is usually around 3mm wide, and it heals naturally without needing any stitches.
*The feel of ICL will vary for each person.
The cost of ICL surgery is listed below. Please feel free to inquire about anything that is unclear about the cost. Payment can be made in cash or by credit card.
*The cost is the same for ordinary lens (for myopia only) and toric lens (also for astigmatism).
I established the Sanno Eye Center in April 2016. I always strive to provide optimal and satisfactory treatment for each patient through careful counselling, detailed tests and precise surgical procedures. All of the doctors at the Sanno Eye Center are world-class surgeons with extensive experience.

He acquired Ph. D in Medicine at the University of Tokyo. Served as Director of the Ophthalmological Department, Musashino Red Cross Hospital and subsequently as the Chairman of the Ophthalmology Department at the Kitasato University School of Medicine. He has held his current position since April 2016. A pioneer in the development of contemporary cataract surgery, he conducted the first ophthalmological surgery using topical anesthesia and developed Toric intraocular lens. He also introduced LASIK, ICL and other refractive surgery to Japan. He is the developer of Hole ICL (ICL KS-AquaPORT) and one of the only two ICL Senior Expert Instructors in Japan (as March 2017). Respected worldwide as an expert in refractive surgery and cataract surgery, his ophthalmic surgery combining the two is highly regarded overseas for enhancing the quality of life (QOL) for many patients.

Board Certified Ophthalmological Medical Specialist, Japanese Ophthalmological Society (JOS); Member, JOS; Member, Japanese Society of Cataract and Refractive Surgery (JSCRS); Member, Japanese Society of Ophthalmic Surgery (JSOS).
He has conducted treatment and research on cataract and refractive surgery under Professor Shimizu since joining the Ophthalmology Department at Kitasato University School of Medicine in 2003. After acquiring his PhD in Medicine there for his research on LASIK, he participated in the first domestic clinical tests for hole ICL and small incision lenticule extraction (SMILE) respectively. Particularly well-versed in ICL, he is one of the only six Japanese qualified as ICL Expert Instructors (as of March 2017). Having experienced LASIK surgery himself, he understands the patient’s perspective in undergoing refractive surgery. He is one of the young leaders of refractive surgery in Japan.
