Regarding reservations for appointments

Q: I am thinking about undergoing the suitability examination...
A: Suitability examinations can be booked on the website or details can be discussed over the phone.
Q: Which days are appointments available?
A: Availability of examination dates and times will change day to day. Clinics are open all year and open times are from 10:00 am to 20:00. Please contact our staff for details.
Q: I am visiting Japan from overseas...
A: Shinagawa LASIK Center has rules and guidelines for overseas travellers visiting Japan for a short amount of time and would like to undergo a LASIK treatment. Please contact our clinic staff for details.

Regarding Safety

Q: Are there any side effects from LASIK treatment?
A: Immediately after the treatment, you may feel some irritation which is called "foreign body sensation". This means that you may feel that "something" (eg: an eyelash), is in your eyelid. Also, feeling dryness is normal as well. Some difficulty seeing in low light conditions is normal as well. Vision will return to normal as the healing progresses and some time has passed.
Q: Are there risks of blindness?
A: LASIK is a treatment which removes the upper layers of the cornea and does not have any effects on the internal parts of the eye. Also in 1995, the FDA (US Food and Drug Administration) approved use of an excimer for refractive treatments and also the MHLW (Japanese Ministry of Health, Labour and Welfare) tested and approved excimer lasers in 2000. Millions of treatments are performed worldwide each year and there are no reported cases of blindness.
Q: Is it possible for a disease to be caused to the eye(s) from surgery?
A: The risks of contamination during a LASIK procedure are quite low, as sanitization is maintained in each operation room using air filters to clean the air and collect fine particles. At Shinagawa LASIK Center, we regularly schedule cleaning inspections and maintenance. All patients should follow the instructions from the staff and doctors for post-operative care to avoid complications.
Q: I am concerned about long term problems, several years in the future.
A: Doctors from various countries around the world have shared data from examinations and clinical studies and LASIK is reported to be a safe treatment to correct refractive errors. With the reported findings of the safety and effectiveness of LASIK, several millions of patients around the world have undergone LASIK treatment with many having their treatment performed over 10 years ago.
Q: What is the possibility of the flap moving or displacing?
A: Living a "regular" lifestyle should not cause the flap to move or displace, but immediately after the treatment day (depending on type of treatment) it is possible for the flap to move if the eyes were to be rubbed or bumped. To avoid this scenario, eye protection will be provided (or can be purchased) especially for concerns during sleep. Please avoid impacts and rubbing the eyes during the first month post-treatment. "Feelings" of the flap being displaced, moved and foreign body sensation (feeling of something like an eyelash, is in the eye) are common sensations. Please feel free to contact our staff if you have any questions or concerns.
Q: Can an infection occur?
A: Some redness and discomfort can occur, but these symptoms will not affect the outcome of the treatment. Infections are very rare, but please contact our staff if you have any concerns.

Regarding the Results

Q: How long will it take to notice results of the treatment?
A: Immediately after most treatments, the vision will be blurry and foggy. 2-3 hours after, vision should be similar to the "target visual acuity" which is discussed during the counselling process at our clinic. Some irritation, itchiness and tears are normal for the first several hours post-treatment.
Q: What level of visual improvement can I expect after treatment?
A: Depending on the condition of the eye, the visual target is different between each patient. In general, the vision through glasses and/or contact lenses should be considered as a great visual result. Please discuss with our doctors about any concerns after the treatment.
Q: Can vision return to a state before treatment?
A: Vision cannot completely return to the original vision. In rare cases, if the eyes/vision is abused, the progression of myopia can occur. If a second treatment is possible, a second treatment can correct the refractive error.
*If a second treatment is required, several visits to the clinic for examinations and consultations with our doctors will be required. Several conditions, such as the current and remaining corneal thickness, will be important for our doctor to safely determine if a second treatment should be performed. Please review the guidelines of the aftercare services for details.

Regarding the Suitability Examination

Q: What kind of tests will be taken for the suitability examination?
A: Our clinics will be required to do examinations of refractive errors, visual acuity & astigmatism , corneal thickness, curve/shape of the cornea, intraocular pressure, ocular fundus (in the back of the eyes) lens and retina. The result of these examinations will allow our doctors to determine what type of treatment would be most suitable. This examination process is required to undergo any type of treatment at the Shinagawa LASIK Center. A consultation with our doctor and counselling with our staff is also important for patients to discuss and ask questions.
Q: Can contact lenses be worn?
A: Wearing contact lenses can leave impressions on the eye which can affect the data required during the examination and surgery. Therefore, following the guidelines and stop wearing contact lenses before visiting our clinic will be mandatory (this includes disposable lenses). After the suitability examination, please keep in mind that limitations for contact lens use will need to be followed before the treatment date.

Q: Will anesthetics be used?

■ Not enough corneal thickness
■ Sickness / Disease related to the eye (eg: cataract, keratoconus, retinal related symptoms)
■ Currently pregnant or nursing (due to taking antibiotics)
* In some cases, lack of corneal thickness, keratoconus may be suitable for other treatments such as Phakic IOL, ICRS (Intrastromal Corneal Ring Segments) or Crosslinking may be an option to replace LASIK. Please consult with or staff and doctors after the suitability examination for more details.
Q: What if I have dry eyes?
A: If you have dry eyes due to eye fatigue or wearing contact lenses, treatment will most likely be possible.

A: Please bring your Japanese national health insurance and identification document(s).

Regarding our Treatments

Q: What are the differences between a LASIK treatment using a microkeratome and femtosecond laser?
A: How a flap is created is the main difference between the two. A microkeratome is a blade which vibrates while creating a flap. A femtosecond laser uses a laser to add more precision and is computer controlled which can create thinner flaps with less risk and complications.
Q: Will anesthetics be used?
A: Similar to the suitability examination, anesthetic eye drops will be used. They will prevent irritation during the examination process. Anesthetics in the form of a needle injection is not required.
Q: Are there any precautions I should understand before treatment?
A: Similar to the suitability examination, please follow the guidelines and stop wearing contact lenses accordingly (see chart shown above). From the treatment day to the next day checkup appointment, please avoid using any cosmetics, hair styling products and fragrances (perfume, cologne, body spray, etc). Please avoid wearing clothing which produces static electricity easily such as wool or other clothing with long fibers. After the treatment vision will appear "misty/cloudy" for several hours, so please avoid driving or riding a bicycle and use public transportation (train, bus, taxi).
Q: Do I need to stay at the clinic overnight?
A: Staying at the clinic is not necessary and also not possible as our clinics do not offer overnight accommodations.
Q: What should I bring to the clinic on the treatment day?
