The cornea—which is only about 0.5mm thick on average—is composed of five layers, and among them, the innermost layer called the endothelium is crucial for the overall health of the cornea. Specular Microscope plays a significant role in examining the health of the corneal endothelium, from examinations before and after ICL (implantable contact lens) to examinations for corneal edema.

Healthy endothelial cells in a 30-year-old male are characterized by the following

• Approximately 2500 to 3000 arrays per square millimeter
• A similarity rate of 60% or more in the shape of cells, resembling a regular hexagon

Contrast Sensitivity Testing Device utilizes precisely controlled sine-wave gratings via a computer to accurately measure visual function. It provides precise information on visual function before and after surgery, serving as a crucial indicator for assessing improved conditions post-surgery.

Electroretinogram (ERG) measures intricate details regarding the condition, progression, and state of the retina by analyzing electrical signals produced by retinal nerve cells when exposed to light. ERG examinations are especially beneficial for evaluating patients prior to cataract surgery and for the diagnosis of retinal conditions or glaucoma. At The One Seoul Eye Clinic, the entire ERG procedure—including preparation and examination—takes about 7 minutes in total, and the electrodes used for the examination are non-intrusive, ensuring optimal comfort for patients

Laser Flare Meter is a device that measures the presence and condition of intraocular inflammation (uveitis, keratitis, scleritis, etc.) based on the number of protein clusters within the aqueous humor, reflected and confirmed through the principle of light scattering after projecting a laser into the eye. This equipment is useful for outpatient examinations and follow-ups after cataract surgery.

Example of Measurement Results

In a normal eye, an average of 2.9 to 3.9 photons is observed per millisecond. If more than 30 photons are observed per millisecond, it is considered indicative of inflammation.

Fundus Camera is the first truecolor confocal scanner that accurately recreates the true colors of the retina. It is capable of capturing images automatically even with a small pupil, providing high-resolution images of the retina and optic nerve

Optical Coherence Tomography (OCT) is essential for the diagnosis and treatment of various retinal conditions such as macular degeneration, diabetic macular edema, epiretinal membrane, and macular hole. Through the vascular imaging mode, it enables non-invasive and more precise examination of subtle vascular changes that were not detectable with conventional equipment

The Ultra-widefield Retinal Imaging Device is an advanced retinal imaging equipment that can capture images of the peripheral retina without dilation. Utilizing the wide-field autofluorescence mode facilitates easy diagnosis and assessment of the progression of macular degeneration. Additionally, the wide-field fluorescein angiography mode allows the diagnosis of vascular changes in the peripheral retina that were previously undetectable with conventional fluorescein angiography

Anterior Segment Ophthalmic OCT Device is a versatile equipment used for various purposes, including measuring axial length and calculating intraocular lens power during cataract surgery, as well as capturing images of the anterior segment for glaucoma screening. Previously, separate tests such as corneal topography, ocular biometry, and gonioscopy were required, but with this device, one can obtain high-precision images and comprehensive measurements in a single examination, significantly reducing the need for multiple tests.

IPL (Intense Pulsed Light) laser is used to treat dry eye syndrome caused by meibomian gland dysfunction, which are oil glands along the rims of the eyelid inside the tarsal plate. The equipment irradiates the IPL laser to destroy abnormal blood vessels and heat to melt and open clogged meibomian glands
