1. Minimization of dry eyes through the AD SYSTEM

Many patients complain about dryness of the eyes after surgery. With AD SYSTEM (Anti-Dry Eye Care SYSTEM), Gangnam St. Mary's Optometry minimizes this post-operative side effect. The AD SYSTEM starts before the surgery and consists of Ultra PLUG installation, LID CARE, and artificial tear application to reduce eye dryness.

1) Installation of ULTRA PLUG

The ULTRA PLUG effectively reduces dry eyes caused by temporary post-operative side effects, contact lenses, or seasonal allergies. Unlike the conventional Permanent Punctal Plug which is permanently inserted into the tear duct, Gangnam St. Mary's Optometry's AD SYSTEM completely injects the ULTRA PLUG into the tear duct so that it may be absorbed within.


LID CARE (Sterile Eyelid Cleansing Wipes) is a technique used to keep the rim of the eyelids clean. It helps form tear ducts and enables the muscles and fat around the eyes to move smoothly, which, in effect, prevents eye dryness. In addition, LID CARE extends the Tear Film Break-up Time by endlessly building new tear films.

3) Customized artificial tears

The degree and experience of post-operative dry eyes vary for individual patients. Therefore, Gangnam St. Mary's Optometry has designed an AD System that thoroughly analyzes each patient's eye condition through accurate measurements of the tear index and dry eye index. In addition to the PLUG insertion and LID CARE, the AD System prescribes customized artificial tears that allow patients to manage dry eyes regularly.

2. Zero Corneal Defects and Pain System

Instead of using alcohol to remove the epithelial flap, the Zero Corneal Defects and Pain utilizes a specially designed AMOIL BRUSH to reduce irritation and pain experienced during conventional surgical procedure. Because the Amoil brush is very fine and soft, it can equalize the corneal surface without damaging the keratocyte and significantly decrease the time spent in scrapping-the period of surgical procedure can be minimized.

3. Zero Corneal Opacity System

For the patient's more rapid recovery and return to daily life, this system is designed for a high-level operation that works concurrently both at the Amniotic Membrane and MMC (Mitomycin-b).

The amniotic membrane is the innermost layer of the placenta consisting of a thick basement membrane and an avascular stromal matrix. It possesses anti-inflammatory, anti-infective, antifibrotic, and antiangiogenic properties, making it ideal for ocular surface reconstruction procedures. Amniotic membrane transplant improves corneal re-epithelialisation, reduces the chance of complications such as corneal opacity, and hastens recovery.

4. Customized Corneal Ablation System

The extremely small spot size of the Gaussian beam profile is used to perform the most appropriate and effective corneal ablation according to the shape of the aspherical surfaces of the cornea. Out of all spot scanning techniques, the Gaussian beam gives the smoothest corneal surface after ablation. In effect, this technique prevents the occurrence of glare or haze and is exceptional at enhancing the visual quality of the patient.

5. The IR Video Tracker System

The IR Video Tracker System has made it possible to design the most stable eye tracking method with automated Pupil, Limbus, and Iris recognition technology. This system significantly reduces light hazing by preserving eye movement during surgery.

6. Clean Operation System

Gangnam St. Mary's Optometry employs a system that completely blocks the entrance of any undesirable matter using a cone for controlled atmosphere (CCA). The CCA setting eliminates possible causes of post-operative complications due to smoke and debris that affect the performance of the laser by changing the temperature, humidity, or pressure. Through this system, Gangnam St. Mary's Optometry aims to achieve the best result possible.

7. Compensation for Torsional Eye Movement System

This system is a complete iris recognition and torsional eye movement compensation system that fundamentally keeps the head and eyes from moving. The position of a person's eyes is prone to change according to the person's overall physical situation. From the way a person is sitting during an eye exam or lying down during an operation to even the slightest turn of the head, the location of the eyes is very sensitive movement and will easily change. Therefore, it is essential to use this compensation system to keep the eyes at a stable position during operation. It is especially needed during corrective surgeries for myopia and wavefront surgeries.
