Hospital Information & Philosophy

Location & Facilities

Gangnam EOS Eye Clinic is a specialized ophthalmology medical institution located near Gangnam Station in Seoul, the center of vision correction surgery in South Korea. It occupies the 18th floor (Examination Center), 19th floor (Surgery Center), and 20th floor (Outpatient Center) of the Samsung Fire & Marine Insurance Seocho Building (Seocho Tower) at 355 Gangnam-daero, Seocho-gu, Seoul, implementing specialized compartmentalized treatment.

Since introducing the Amaris laser for the first time in Asia in 2008, the clinic has continuously upgraded equipment and conducted clinical research to improve the safety and recovery speed of vision correction surgeries.

Space Revolution & Patient Experience (PX)

A key feature is its 'Space Revolution Project', which presents a new paradigm of medical service. This project considers patients' lifestyles and psychological stability beyond simple vision correction, aiming to be a 'hospital where space is the protagonist'.

Lounge EOS Concept

The hospital waiting area is transformed into a premium lounge offering specialty coffee and desserts, collaborating with professional baristas and famous dessert brands. This strategy aims to alleviate patient tension and make the hospital visit a positive experience, even expanding the brand by opening 'Lounge EOS Seongsu' in Seongsu-dong.

Examination and Medical System

  • **Precision Examination:** About 70 types of precision tests are performed over approximately 2 hours before surgery, including Avellino DNA testing, corneal topography (5 methods), and retinal examinations.
  • **Safety System:** Equipped with retinal laser equipment to immediately treat retinal abnormalities without transferring the patient to a university hospital.

Major Procedures & Technological Capabilities

3.1 2Day LASEK

The signature procedure, researched and developed by Director Oh Jung-woo since 2010. It's an 'All-Laser LASEK' method using the Amaris Red 1050RS laser, ablating the epithelium and stroma in one step using only a laser.

  • **Minimized Damage:** Approximately 40% reduction in corneal epithelial damage compared to existing methods, leading to less pain and faster recovery.
  • **Fast Recovery:** Protective lens removal and return to daily life within an average of 2 days (48 hours) after surgery.
  • **Safety:** Smooth corneal ablation surface ensures excellent vision quality and reduces possibility of corneal haze and myopic regression.
  • **Data-Driven:** Director Oh Jung-woo transparently discloses key indicators such as ablation amount, residual cornea, pupil size, and ablation area, and performs surgery based on medical standards.

3.2 Smart LASIK (5th Generation SMILE LASEK)

EOS Eye Clinic implements Smart LASIK by introducing Schwind's latest equipment, 'ATOS'.

  • **Equipment Features (ATOS):** Faster laser firing speed (4MHz, compared to VisuMax's 500kHz) and equipped with a 7-dimensional eye tracking device to compensate for micro-movements and rotation during surgery.
  • **Custom-Fit Technology:** Surgery is customized by analyzing the corneal thickness and high order aberrations of each individual patient. Low Energy is used to leave the corneal surface smooth, resulting in fast visual recovery and minimized light scattering.
  • **Safety:** Since no corneal flap is created and the lenticule is removed through a micro-incision of about 2mm, the incidence of dry eye syndrome is low and it is resistant to external impacts.

3.3 ICL Lens Implantation and Presbyopia/Cataract Surgery

  • **ICL Lens Implantation:** A surgery where a special lens is inserted inside the eye without cutting the cornea, suitable for patients with high myopia or thin corneas. Director Oh Jung-woo was selected as a 'Best Skilled User' for Toric ICL (for astigmatism correction) and holds the certification for the highest number of procedures in Korea.
  • **Presbyopia/Cataract:** Simultaneously corrects presbyopia and cataracts through laser cataract surgery and multifocal intraocular lens implantation.

4. Equipment and Technical Infrastructure

Gangnam EOS Eye Clinic operates world-class advanced equipment for optimal surgical results.

Amaris Red 1050RS

The core equipment for 2Day LASEK, boasting the fastest firing speed of 1050Hz among existing excimer lasers.

  • **7-Dimensional Eye Tracking:** Predicts and fires lasers based on 7 dimensions of movement, including not only horizontal and vertical movements of the eye but also rotation and tilt. Accuracy is maximized through 'Latency-Free (0-second delay)' technology.
  • **Minimized Thermal Damage:** The fast firing speed shortens surgery time, preventing the cornea from drying out or sustaining thermal damage.

SCHWIND ATOS

Femtosecond laser equipment for Smart LASIK.

  • **Precise Astigmatism Correction:** The eye rotation compensation function allows for accurate alignment of the astigmatism axis for correction, resulting in excellent vision quality.
  • **Minimal Incision:** Micro-incision technology minimizes corneal damage, maintaining structural stability after surgery.

Reputation and Comprehensive Analysis

Positive Evaluations

  • **Trust in Surgical Results:** Many patients confirm that "it was possible to remove the protective lens in 2 days and return to daily life." Trust in Director Oh Jung-woo's surgical skills and conservative safety standards is particularly high.
  • **Systematic System:** Operations from examination to surgery and post-operative care are systematic, and staff are frequently praised for being friendly and professional.
  • **Pleasant Environment:** There are favorable reviews that the luxurious interior and services (coffee, dessert) of Lounge EOS relieve the boredom of waiting times.

Negative Evaluations & Considerations

  • **Long Waiting Times:** Due to thorough examinations and a large number of patients, waiting times can be long even with a reservation. Eye exams alone take 1-2 hours, and including the wait for consultation, it often takes more than half a day.
  • **Cost:** There are opinions that the surgical costs are set somewhat higher than other hospitals as they provide premium equipment and services (e.g., 2Day LASEK is around 2.0~2.5 million KRW).
  • **"Factory-like" Feel:** Due to the large scale of the hospital and the high volume of patients, some patients may feel it is like a "factory-type hospital" or feel that the counseling manager's response is mechanical.

Conclusion & Core Values

Gangnam EOS Eye Clinic and Representative Director Oh Jung-woo are a successful case of combining the essence of medicine, **'Safety' and 'Technology'**, with the patient experience elements of **'Space' and 'Service'**. Director Oh Jung-woo's research achievements in 2Day LASEK are the hospital's core competitiveness, which, combined with conservative surgical criteria, forms a high level of trust. However, high costs and long waiting times act as opportunity costs that patients must accept when choosing premium medical services.

This report was written based on the latest data, patient reviews, and academic materials from the 2024-2025 period, suggesting that Gangnam EOS Eye Clinic can be a very strong option for patients considering vision correction surgery when technical perfection and safety are prioritized.
