WHAT IS THE JAPANESE STANDARD MYOPIA SURGERY PROCESS?
Myopia surgery is a popular solution that helps millions of people with refractive errors around the world escape their dependence on glasses or contact lenses. To ensure safety and optimal effectiveness, Japan International Eye Hospital pioneers the application of an in-depth eye examination process before myopia surgery according to strict Japanese standards, ensuring that each examination step is performed professionally and methodically, helping patients assess the appropriateness and choose the optimal myopia surgery method for themselves.
Myopia surgery procedure according to Japanese standards at Japan International Eye Hospital
Refraction test
Patients are assessed for subjective refraction (myopia, hyperopia, astigmatism) on the TRK-2P automatic refractometer. This step will also provide the corneal curvature index and central corneal thickness for reference.
Intraocular pressure test
Patients are assessed for intraocular pressure on the TRK-2P automatic refractometer, to ensure that intraocular pressure is within a stable range of 10 - 21 mmHg, meeting the surgical conditions.
Visual acuity test
The patient's vision without glasses, vision with old glasses (if any), and maximum corrected vision are determined through 6 specialized tests, with the support of an optometrist and a 3D vision testing system. Through this test, abnormalities in eye movement, strabismus, inhibition, or other visual function abnormalities can also be detected.
The patient may be prescribed eye drops to remove the accommodation factor in the eye, in order to most accurately assess the refractive error for the doctor to use as a basis for specifying parameters during surgery.
Cornea mapping
The patient is examined with the Pentacam HR machine to evaluate the corneal structure and identify abnormalities in the cornea.
Corneal thickness measurement
With the Pentacam HR imaging step, patients can also determine the corneal thickness to check the suitability of the eye for laser surgeries such as ReLEX SMILE, Femtosecond Lasik, SBK Lasik.
Screening for retinal degeneration due to severe myopia
This test step is reserved for patients with severe myopia over 6 diopters. Patients will be examined with the Optos Daytona wide-angle retinal color camera to assess retinal health, helping to detect degeneration, tears, and retinal detachment (if any) for timely treatment.
Measuring the anterior chamber depth and measuring the anterior chamber angle
This test step is performed for patients with thin corneas under 500 μm and/or myopia of 6D or more. Patients will be examined on the Cirrus 6000 machine to assess the suitability of the eye for Phakic surgery.
Checking corneal diameter and central corneal thickness
The patient will have their corneal diameter and central corneal thickness checked on the IOLMaster 700 machine, serving to calculate the parameters of the Phakic intraocular lens. This step will also provide reference indexes for corneal curvature, corneal astigmatism and astigmatism axis.
Eye examination on a biomicroscope
The patient will have their eyes examined on the TAKAGI Slit Lamp machine with an ophthalmologist, to observe the surface of the eyeball, identify abnormalities such as inflammation, dry eyes, and observe the central retina.
Doctor advises on surgical methods
Through the indicators obtained from the examination steps, the doctor will advise on appropriate and optimal surgical methods corresponding to the patient's eye condition. In addition, the doctor will also indicate the risk of corneal and retinal diseases (if any) and make recommendations and treatment indications if necessary.
Consulting and answering questions with Consultants
With the goal of helping patients have full information before deciding on surgery, consultants will answer patients' concerns and questions about the mechanism and method of surgery, and at the same time guide them on eye care before and after surgery, and the steps to take to prepare for surgery.
Advantages of the myopia surgery examination process according to Japanese standards
Thorough: The in-depth examination and consultation process before myopia surgery with 11 steps according to Japanese standards is carried out thoroughly and carefully by experienced, well-trained technicians, nurses and doctors.
Accurate: Japan International Eye Hospital owns a system of modern examination and imaging diagnostic equipment with machines such as Optos Daytona, Cirrus 6000, IOLMaster 700, Pentacam HR, ... to help test results achieve high accuracy. In addition, each parameter is determined through 2-3 examination steps to compare and verify accuracy.
Comprehensive: Not only checking the input parameters for surgery, the in-depth examination and consultation process before surgery also includes examination steps to help screen for retinal diseases for high-risk patients, ophthalmic examination to eliminate regulatory factors to comprehensively assess eye health, make recommendations on the risk of other eye diseases (if any), thereby ensuring maximum treatment effectiveness.
Transparency: All examination results are returned to patients for reference. Information on surgical methods, advantages and disadvantages of each method and patient questions will be thoroughly and objectively answered by doctors and consultants, helping patients have full information before deciding on surgery.
Currently, the Japanese-standard myopia examination and surgery package is free every Wednesday, Saturday, and Sunday. The examination package is for patients from 18 to 45 years old, with refractive errors (myopia, hyperopia, astigmatism), interested in refractive surgery methods. At Japan International Eye Hospital, the medical staff respects each individual's surgical decision, patients can rest assured to visit without worrying about being bothered by messages or calls.
