Gwangju Shinsegae Eye Clinic Introduces State-of-the-Art Anterior Segment OCT Device 'CASIA 2'

Three-Dimensional 360-Degree Analysis Now Possible

Gwangju Shinsegae Eye Clinic announced on January 21 that it has introduced the state-of-the-art anterior segment OCT (Optical Coherence Tomography) equipment, 'CASIA 2,' for the first time in the Gwangju and Jeonnam regions, in order to dramatically enhance the safety and accuracy of implantable collamer lens (ICL) and cataract surgeries.

Developed by Japan's TOMEY Corporation, CASIA 2 is a high-resolution device that creates three-dimensional (3D) images of the anterior segment of the eye. Currently operated only at university hospitals and some ophthalmology clinics in Korea, this device is recognized as optimal for lens implantation surgery, as it can analyze the space inside the eye where the lens will be inserted from a full 360-degree perspective.

The core feature of CASIA 2 is its ultra-high-speed scanning technology, capable of 50,000 A-scans per second. In just 0.3 seconds, it can capture up to 13 mm in depth from the front of the cornea to the back of the lens, enabling a more precise understanding of the internal structure of the eye. This allows for three-dimensional analysis of the angle between the iris and cornea (anterior chamber angle), anterior chamber depth, and lens tilt, making it possible to determine the ideal lens size and insertion position tailored to each patient's eye condition.

Because lens implantation involves directly inserting a lens into the eye, even a small error in lens size selection can lead to complications such as cataracts or glaucoma. CASIA 2 not only enables thorough spatial measurement before surgery, but also allows for real-time monitoring of whether the lens is stably positioned after surgery, thereby improving both surgical outcomes and patient satisfaction.

In addition to lens implantation, CASIA 2 is utilized for diagnosing various eye diseases and planning surgeries. For cataract surgery, it accurately measures the curvature and tilt of the lens to calculate the optimal intraocular lens power, and works in conjunction with the Catalys laser system to plan precise surgical procedures.

Furthermore, its 360-degree anterior chamber angle analysis function enables early detection and management of risk factors such as angle-closure glaucoma. By imaging an area up to 16 mm in diameter, it can diagnose subtle corneal diseases such as keratoconus.

Jae-bong Kim, the clinic's director, who has performed ICL surgeries for over 20 years and has been designated as an ICL Reference Doctor by lens developer STARR Surgical, has further strengthened the clinic's medical system with the introduction of this equipment.

Director Jae-bong Kim stated, "As demonstrated by numerous clinical studies both in Korea and internationally, including those published in the Korean Journal of Ophthalmology, CASIA 2 provides extremely high reliability in ocular parameter measurements. By combining the expertise of our skilled medical staff with the precise data from advanced equipment, we will do our utmost to ensure that even patients with high myopia or astigmatism can safely restore their vision without worrying about complications."
