iLASIK® & Other Surgery Procedures

Other Surgery Procedures

WE OFFER THE BEST VISION CORRECTION FOR EACH INDIVIDUAL NEEDS

Kobe Kanagawa Eye Clinic offers not only the LASIK procedures but also various kinds of other vision correction such as our premium option the ICL. Depending on the result of your eye exam and your life style, we would recommend the best vision correction available for you.

As our fingerprints differ from each other, the shape of  the cornea and its thickness are the same; no two are alike. With the latest medical technology, it is possible to create a customized Laser irradiation program just for you. Your "acuity of vision" will change by the world's highest quality medical treatment.

Unlike the conventional LASIK procedures, the computerized femtosecond laser is used to create a flap instead of using a microkeratome. After creating the flap on the cornea by using IntraLase laser, the flap is turned over, and then another laser irradiation is applied to change the curvature of the cornea in order to correct the vision.

Epi-LASIK is  the same as the regular LASIK procedure, which is a vision correction by laser irradiation on the cornea. This procedure can be offered to the patients who would be unable to receive the regular LASIK procedure such as, those who have a thinner cornea and /or athletes who are required to take hard impacts.

LASEK is well suited for patients who have thin corneas, do activities such as martial arts where impacts around the eyes are possible and have an irregular corneal shape or small eyes that are difficult to treat by LASIK or Epi-LASIK.

PRK is a Laser Vision Correction, which has been used long before the LASIK procedure became available. Unlike LASIK, it does not require flap creation. Therefore, this procedure is suitable for those who have thinner corneas and/or athletes who are required to take hard impacts; similar to the Epi-LASIK procedures. However, the PRK procedure can be offered especially to those who have smaller eye sockets or cornea shapes which may be impossible to utilize a medical device to create a flap.

It customizes the Laser irradiation data for each individual eye which has a unique condition like the fingerprints. It achieves the Personal Best Vision which could not be achieved by glasses or contact lenses.

  • * Premium iLASIK® initially includes the Option : CustomVue treatment fee.
  • * CustomVue can be added to Epi-LASIK, LASEK and PRK as an option.

The ICL is an Implantable Contact Lens that works with the eye to correct vision. Unlike traditional contact lenses that go on the surface of the eye, the ICL is positioned inside the eye between the iris (the colored part of the eye) and the natural lens where it stays indefinitely. If your vision changes dramatically, however, it can be removed from the eye.

ICRS (Intrastromal Corneal Ring Segments) implant suits patients who are not eligible for laser refractive surgeries like LASIK or Epi-LASIK

Cataract treatment is a lens implant procedure that removes a cloudy crystalline lens and implants an artificial lens (IOL) instead.

iLASIK®

As our fingerprints differ between each individual, the shape of the cornea and its thickness are the same; no two are alike. With the latest medical technology, it is possible to create a customized Laser irradiation program just for you. The "acuity of vision" will change through the world's highest quality medical treatment.

Combined 3 medical technology

Three advanced medical technologies were unified as the latest vision correction treatment in the United States and Europe. The number of the patients who choose this treatment is rapidly increasing. iLASIK® is a LASIK treatment which consists of the three most advanced medical technologies.

Wave Scan

The technology to measure individual cornea condition precisely and to program the ideal Laser irradiation.

Intralase FS60

The technology to create a flap with controlled depth and width safely by using a Laser beam.

VISX Star S4 IR

The technology to irradiate Laser beams safely and precisely without burdening your cornea.

Safety and stability of iLASIK®

Lasik was approved by the U.S. Department of Defense and the National Aeronautics And Space Administration (NASA), based on the effectiveness and superior results of iLASIK®.

Safety and stability of visual acuity was tested and approved under extreme conditions, including acceleration in a fighter jet, change in onboard atmospheric pressure at the time of launch, etc, and work in outer space. The all-laser LASIK technologies, which utilize Wavefront guided and Femtosecond lasers, have also been cleared for U.S. military personnel, including most recently Air Force pilots.

iFS IntraLASIK

Unlike conventional LASIK procedures, the computerized femtosecond laser is used to create a flap instead of using a microkeratome. After creating the flap on the cornea by using IntraLase laser, the flap is turned over, and then another laser irradiation is applied to change the curvature of the cornea in order to correct the vision.

For patients with the following cases

- Thinner corneas
iFS IntraLASIK can be offered to those who have a thinner cornea, which may be difficult to be accepted for LASIK treatment procedures using the microkeratome.

THE PROCEDURE

It creates a stable flap safely by using laser beams

Unlike using microkeratome, it is a non-blade procedure for flap creation. The iFS Femtosecond Laser induced high-order aberrations and precise control of flap dimensions which helps avoid the peripheral lamellar structure, which is vital to the biomechanical stability of the cornea. Precisely centered, accurately sized flaps, dimensions designs are based on patient factors, such as corneal thickness, steepness, diameter and pupil position. The flap created by iFS Femtosecond Laser is strong and has less risk of shifting. It doesn't generate heat nor cause pain, therefore it is more comfortable for patients compared to conventional methods.

It creates smoother flap surface for laser irradiations

Since it uses laser beams controlled by a computer, the flap has a perfectly round shape and a smooth, even surface on the cornea. Unlike microkeratome, when creating a flap, it does not require liquid solutions. It interferes with the excimer laser irradiations. Without solutions, the ablation by the excimer laser improves its accuracy and it delivers outcomes with superior vision correction .

Epi-LASIK

Epi-LASIK is the same as regular LASIK procedure, which is vision correction by laser irradiation on the cornea. This procedure can be offered to patients who would be unable to receive a regular LASIK procedure such as, those who have a thinner cornea and/or  athletes who are involved in high-contact sports.

For patients with the following cases

・ For those who have thinner corneas
Epi-LASIK may be applicable to those who do not have enough cornea thickness to receive a regular/conventional LASIK procedure. Compared to PRK procedures, it offers quicker and less discomfort during post-operative recovery.

・ Athletes who are involved in high-contact sports/impact are their eyes.
For athletes, especially for wrestlers and boxers, an Epi-LASIK flap is more durable; for example: punches to the head..

THE PROCEDURE

Only the thin sheet of cells from the epithelial layer is safely separated and lifted from the permanent structure of the cornea by using an Epi- Keratome. It enables us to preserve enough thickness and not disturb the strength of the cornea. The procedure can be applied to patients who have thinner corneas. The epithelial layer, which was used to create the flap, will grow back naturally by metabolism. Therefore, the flap is durable for "shifting", even if  one were to receive a strong punch to the eyes.

LASEK

LASEK is a refractive surgery to correct refractive errors by removing the corneal epithelium with alcohol and a special medical instrument then irradiating an excimer laser onto the cornea.
This procedure is suitable for people who have a thin cornea or participate in aggressive sports like full contact martial arts.

For patients with the following cases

・ For patients with the following cases
Insufficient corneal thickness
Some can be suitable for LASEK even if you are unsuitable for LASIK, due to having a thin cornea.
- Playing contact sports which taking strong impact(s) around the eyes like combat sports are possible.
- Having difficulty undergoing an Epi-LASIK treatment.
- Having small eyes

THE PROCEDURE

LASEK (Laser-assisted sub-epithelial keratectomy), uses special medical alcohol and removes the corneal epithelium, then an excimer laser is irradiated to correct myopia, hyperopia or astigmatism. LASEK is widely used for people who are poor candidates for LASIK due to having a thin cornea or poor candidates for Epi-LASIK or LASIK for specific reasons.
The removed corneal epithelium will regenerate naturally. LASEK, when compared to LASIK, there is no risk of a flap slipping from a strong impact and is a safe procedure.
LASEK is well suited for patients who have thin corneas, do activities such as martial arts where impacts around the eyes are possible and have an irregular corneal shape or small eyes that are difficult to treat by LASIK or Epi-LASIK

PRK

PRK is a Laser Vision Correction treatment, which has been conducted long before LASIK procedures became available. Unlike LASIK, it does not require creation of the flap. Therefore, this procedure is suitable for those who have thinner corneas and/or athletes who take extremely hard body contact, which is similar to Epi-LASIK procedures. However, PRK procedures can be offered to those who have smaller eye sockets or cornea shapes which may be impossible to utilize other medical devices to create a flap.

For patients with the following cases

・ those who have thinner corneas
PRK procedures can be offered to those who do not have enough cornea thickness to receive regular conventional LASIK.

・ Athletes who take extremely hard body contact.
Athletes who take high-impacts.
Since PRK does not require the creation of  a flap, there is no risk of flap shifting.

THE PROCEDURE

The epithelium, the thin layer of clear protective skin that covers the cornea, will be gently removed by an excimar laser irradiation. Then, another irradiation will be applied to correct the myopia, astigmatism and/or hyperopia vision. Unlike LASIK procedures, it does not require a flap so it can be offered to those who do not have enough cornea thickness to receive regular conventional LASIK. It does not have the risk of flap dislocation possibly caused by extremely hard body contact.

OPTION : CustomVue

Just like our fingerprints, the cornea shape and thickness are different for all of us. CustomVue is an individualized laser vision correction procedure by designing a customized program of laser irradiation patterns. Therefore, it can correct the finest distortions on the cornea which can not be corrected by glasses or contact lenses or conventional LASIK procedures. CustomVue is the most advanced medical technology that will provide you not only with a better vision correction outcome, but will also improve the quality of vision with better acuity. (The quality of the vision means better acuity when you see objects in the distance.)

CustomVue merits

  • The quality (acuity) of the vision improves even at the same 20/20 vision range.
  • Reduces halo, glare at night compared to Conventional LASIK.
  • Lower rate of touch-up/enhancement surgery.

CustomVue demerits

  • Depending on the patients refractive errors, laser ablation amount of cornea may be bigger.
    (If the patient's cornea has enough thickness, this is not a concern.)
  • *Premium iLASIK® initially includes the Option : CustomVue treatment fee.
  • * CustomVue can be added to Epi-LASIK, LASEK and PRK as an option.

Phakic IOL (ICL)

The ICL is an Implantable Contact Lens that works with the eye to correct vision. Unlike traditional contact lenses that go on the surface of the eye, the ICL is positioned inside the eye between the iris (the colored part of the eye) and the natural lens where it stays indefinitely. If your vision changes dramatically, however, it can be removed from the eye.

The ICL Advantages For patients

Many vision correction procedures promise an improved level of vision, but few vision correction alternatives offer the quality and features found with the ICL.
These include:
・Sharp, Clear Vision
・Does not induce dry eye syndrome4
・Excellent Night Vision
・Great for those with thin corneas
・UV protection built into the biocompatible lenses
・A typically quick, 10 to 20 minute procedure and most people are able to resume daily activities in just a few short days with clearer vision
・Treats moderate to high myopia (nearsightedness), Hyperopia* (farsightedness) and astigmatism.
* Hyperopic lenses require an additonal tiny opening in the colored portion of your

What to Expect During the ICL Implantation Process

The Day of Surgery It is important that you do not drive yourself home so make arrangements before the day of surgery. Prior to implantation, you will receive anesthetic eye drops to minimize any discomfort. Your surgeon may also administer a sedative. Then, a small opening will be made into your cornea that will be used to insert and position the lens. Next the lens is injected, gently unfolding in your eye. That's it, the procedure usually takes about 20 minutes! Recovery time is short. A few hours after the procedure you will be able to leave the clinic.

After Surgery (Just a few days) To complete the procedure, the surgeon will provide eye drops to help prevent infection and inflammation. You will continue to use these drops for several days once you are home. DO NOT rub your eyes, especially for the first 3 to 5 days.

ICRS

Keratoconus treatment with Intrastromal Corneal Ring Segments (ICRS)
Keratoconus is a progressive eye disorder, which causes the cornea to thin partially and the thinned portion weakens and begins to bulge outward.
It is possible for Keratoconus to occur in both eyes, but it will not always develop simultaneously. As the cornea bulges conically and becomes more irregular in shape, it causes progressive nearsightedness and irregular astigmatism that cannot be corrected by glasses or contact lenses. Typical initial symptoms begin from blurred vision, but most patients have no subjective symptoms and it can only be diagnosed by a detailed eye exam.
The exact cause of keratoconus is unknown so far. Some studies have indicated that hormones; because there is a gender difference in development (3:1 of males:females in Japan), or rubbing of the eyes and atopic disorders might be causes of keratoconus.
At an early stage of keratoconus, correction by using a contact lens is possible. But when the symptom worsens, wearing a contact lens becomes difficult and the cornea becomes opaque as it worsens. The final method of treatment for keratoconus may result through a corneal transplant.
ICRS treatments suit patients who are not eligible for laser refractive surgeries like LASIK or Epi-LASIK
Arched ring segments with a diameter of 5-7 mm are implanted in the cornea, which treats myopia and astigmatism by changing corneal shape. One or two ring segments are used for this treatment. In the past, the cornea was manually incised to insert the ring segments, however we now use state-of-the-art laser technology of the iFS Femtosecond Laser to incise the cornea, which makes the procedure more extremely safe and accurate

* Approximately 20% of cases, this treatment cannot change the refractive errors. But, as the irregularity of the corneal shape would improve, reduction of astigmatism or vision correction using glasses and contact lenses would become possible.

For patients with the following cases

・Progressive keratoconus
Increase the strength of the cornea, which slow down the progression of keratoconus.

・ Patients who have possibilities of keratoconus occurring in the future, which may be triggered by undergoing a laser vision correction such as LASIK.

・ Patients, who have myopia up to -3D, can expect improvements of unaided visual acuity.

・ Patients who have minimal improvement of visual acuity using glasses or contact lenses.
By improving the corneal shape, wearing glasses and contact lenses would become possible.

THE PROCEDURE

Ring segments are made of PMMA (polymethylmethacrylate). This material also has a history of being used for intraocular lenses for over half a century. We use two types of intrastromal corneal ring segments, Keraring by MEDIPHACOS and INTACS or INTACS SK by Addition Technology, Inc. According with the diopters of myopia and astigmatism, the surgeon who is licensed by these companies selects the best ring segment for each patient.
In the case which any trouble occurs, the eye can be restored to its original condition prior to implantation by removing the ring segment.

Multifocal IOL

Cataract treatment with Multifocal Intraocular lenses (Multifocal IOLs)
Cataract is an eye disease in which the clear lens of the eye becomes cloudy and opaque, causing decrease in vision. These images describe the comparisons between a normal eye and an eye with cataract. In a normal eye, light passes through a transparent lens to the retina. If the lens is clouded by the effects of cataract, the light passing through is disturbed.

For patients with the following cases

・Progressive keratoconus
Increase the strength of the cornea, which slow down the progression of keratoconus.

Patient who has developed cataract and feel the inconvenience of everyday life that glasses are not enough.
