Examination instruments

OCT (Optical Coherence Tomography)

Take photograph of retina. This test can help to determine detailed data of your eyes like a MRI. This test is used to examine the glaucoma and loss of eye sight.

Auto Ref/Kerato/Tono/Pachymeter TONOREF™ III

Number: 227AABZ00095000

Over view:This machine enables to have the refraction test and Eye Pressure Measurement together.You will be asked to look through the device which contains lenses of different strengths that can be moved into your view. To measure the pressure inside your eye using a non-contact tonometry with an “air puff”.

Purpose:Refraction test can help to determine the extent of poor vision and monitor a person who is being treated for an eye disease. Eye pressure measurement is used for determining whether you have glaucoma, a disease which causes pressure to build up inside your eyes and may result in blindness.
Visual acuity testing

In this test, you will put on different lenses to correct the refractive error such as myopia, hyperopia, and astigmatism, which will help to find out your best vision.
Slit-lamp microscopy

Examine the cornea, iris, lens and the anterior chamber. This test can help to determine of itching and ache for your eyes.
Applanation tonometry

This test measures fluid pressure inside your eye. In this test, an equipment called slit lamp will be used, and you will be asked to put your chin and forehead on the support. The doctor will use a flat-tipped cone and put it on your eye. The tonometry measures the amount of pressure needed to flatten your cornea.
Retinal Examination(Ophthalmoscopy)

This exam needs to open your pupil. Eye drops may be placed in your eyes to widen (dilate) your pupils. This test can be help to determine cataract and another inflammation of crystalline lens.
Fluorescein angiography

In the procedure, a fluorescent dye is injected into the bloodstream, and the dye highlights the blood vessels in the retina. Photographs are taken to record the blood flow in the retina, and these pictures can help your eye doctor see the blood vessels and other structures better.
Pseudoisochromatic plates

Ishihara test is one of the most common examination for color blindness. Patients would see a set of dotted plates which show some numbers hidden in the design, and the it is efficient for detecting colour vision deficiency. We also have Panel D-15 test which examines the type and its severity of the colour blindness.
Humphrey Field Analyzer

This test can help to determine the loss of your eye sight. You will rest your chin and forehead on a support that keeps your head steady. There are FDT, Humphrey Field Analyzer and Gold man Field Analyzer in our eye clinic.
Frequency doubling technology (FDT)

Frequency doubling technology (FDT) is an instrument to determine field vision loss. It is easily used and has high sensitivity to determine the perimeter loss of vision of glaucomatous, retinal, neurological disorder patients.
Goldmann Perimetry

Goldmann Perimeter examines the range and the sensitivity of your vision. While you are looking at the fixation lamp, an examiner move the light from outside towards the center, and tests the range of your vision.
Unlike Humphrey Field Analyzer and FDT Perimetry, this method is able to test the entire range of peripheral vision, and provides the result as a map which helps confirm a diagnosis of the cause of the symptom.
Specular Microscope

Cataract surgery, LASIK and wearing contact lens for a long time may cause loss of corneal endothelial cells. This instrument examines and analyzes the corneal endothelium, and is efficient fo diagnosis of corneal disease too.
Amsler Grid Test

By taking a look of test chart, we can check distortion and lack of your vision.
Gonioscopy

Checks for blockages in the area where fluid drains out of the eye.
This test can help to determine whether or not you need laser exam. Also this exam used to look at the front part of the eye between the cornea and the iris.
Flow examination

We test for obstruction of the lacrimal passage from the punctum to the canaliculi and nasolacrimal duct by running saline through. This test is efficient to diagnose the obstructive illnesses or infections in the lacrimal passage.
Flicker MiniⅡ

Flicker MiniⅡcan measure Critical Fusion Frequency (C.F.F.) and determines optic nerve diseases.
Adeno Virus Test kits

This test is valid if there is a high possibility of epidemic keratoconjunctivitis. By a reagent that quickly detects the adenovirus antigen that causes epidemic keratoconjunctivitis, it can check whether or not you have been infected with the virus.
Allergy test (Blood test)

It can determine the cause of 39 types of allergies at once.
Hertel Exophthal monometer

It can measure the degree of forward displacement of the eye in exophthalmos.
Optical ocular axial length measuring instrument

It provides many measurements required for cataract surgery at once.
For example, it can measure the axial length, corneal curvature, anterior chamber depth and lens thickness without touching eyes.
Ocular axial/ Corneal thickness measurement instrument (A-mode echogram)

It is ultrasonic ocular axial and corneal thickness measurement instrument.
These results are measured by using refractive echo and displayed as waveforms.
Schirmer’s test

Schirmer’s test determines whether the eye produces enough tears to keep it moist. This test is used when a person experiences very dry eyes or excessive watering of the eyes. It poses no risk to the subject. A negative (more than 10 mm of moisture on the filter paper in 5 minutes) test result is normal. Both eyes normally secrete the same amount of tears. We use anesthesia eye drop before test to prevent coming out tears by stimulating of inserting papers.
