Refractive surgery has evolved significantly over the past three decades, offering millions of people around the world freedom from glasses and contact lenses. Among the most revolutionary advancements is the SMILE procedure, a minimally invasive alternative to traditional LASIK that uses a small incision to correct vision. At the forefront of this innovation is SNU Eye Clinic in Seoul, where the introduction of SMILE PRO has further transformed the field of vision correction. This advanced technology combines robotic precision, faster recovery times, and unparalleled safety, making it one of the most sought-after treatments for myopia and astigmatism correction today.
SNU Eye Clinic has established itself as a global leader in laser vision correction, having treated over 1,200 international patients between 2022 and 2023. Under the leadership of CEO Dr. Chung Eui-sang, who has been performing SMILE surgeries since 2011, the clinic is among the first worldwide to adopt ZEISS-certified equipment such as the VisuMax 800. This cutting-edge platform powers SMILE PRO, an upgraded version of the original procedure that enhances patient comfort and surgical precision through robotic guidance.
Understanding the evolution from LASIK to SMILE PRO
LASIK has been a widely popular vision correction surgery for decades, but it involves creating a corneal flap, which can sometimes lead to complications such as dry eyes, flap dislocation, or extended healing times. The development of SMILE or 스마일라식 (Small Incision Lenticule Extraction) addressed many of these issues by eliminating the need for a flap and reducing the incision size to just a few millimeters.
SMILE PRO builds upon this foundation, bringing further refinement to the procedure. It employs robotic-assisted alignment technology and faster laser cutting speeds, which significantly reduce surgery duration. The result is a more comfortable experience for the patient, improved surgical consistency, and a faster return to everyday activities. For many individuals, this means regaining clear vision without glasses or contact lenses in just a matter of days.
Robotic-guided laser precision
The defining feature of SMILE PRO at SNU Eye Clinic is its robotic-guided laser technology. Unlike manual procedures where alignment and incision rely heavily on surgeon dexterity, the robotic system ensures that every cut is performed with exact precision. This minimizes the risk of human error and enhances safety, particularly for patients with complex eye conditions such as high myopia, astigmatism, or corneal asymmetry.
By leveraging this technology, SNU Eye Clinic ensures that each patient’s surgery is tailored to the unique shape and characteristics of their eyes. The ability to customize the procedure not only maximizes outcomes but also significantly reduces postoperative discomfort and complications.
Faster patient recovery and comfort
One of the most appealing advantages of SMILE PRO is the speed of recovery. Patients often notice improved vision within 24 to 48 hours, with most returning to normal routines shortly after. Since the incision is smaller compared to LASIK, there is less disruption to the corneal surface and nerves, which results in reduced dry eye symptoms and faster healing.
SNU Eye Clinic further enhances recovery by employing state-of-the-art postoperative care protocols. Regular follow-up visits, supported by advanced imaging technologies like OCT, allow the medical team to monitor healing and ensure long-term stability. The combination of modern technology and experienced surgeons helps patients feel confident about the safety and effectiveness of their treatment.
Patient-tailored SMILE PRO procedures
Not every patient’s vision correction needs are the same, and SNU Eye Clinic recognizes this through its emphasis on patient-tailored procedures. Before surgery, comprehensive diagnostic evaluations are performed, including corneal topography and 3D imaging. These tests allow the clinic to identify factors such as corneal asymmetry, tear film stability, and refractive error severity.
For patients with high myopia or dry eye conditions, special adjustments can be made during the SMILE PRO procedure to ensure optimal outcomes. This personalized approach is what distinguishes SNU Eye Clinic from many other centers and is a key reason why patients from around the globe travel to Seoul for treatment.
The role of ZEISS VisuMax 800 in SMILE PRO
The ZEISS VisuMax 800 is one of the most advanced femtosecond laser systems available today, and it forms the foundation of SMILE PRO. This technology allows the procedure to be completed more efficiently than earlier models, with reduced suction time and higher precision. For patients, this translates into a smoother experience during surgery, reduced anxiety, and quicker recovery afterward.
Being ZEISS-certified means that SNU Eye Clinic meets rigorous global standards for equipment and surgical technique. Patients can trust that they are receiving care on par with leading eye hospitals in Europe and North America, but with the added benefit of personalized treatment plans and international patient support services.
Why international patients choose SMILE PRO at SNU Eye Clinic
With more than a decade of experience in SMILE LASIK, Dr. Chung Eui-sang and his team have built a reputation as pioneers in this field. The clinic’s emphasis on advanced technology, robotic precision, and patient-specific customization makes it an attractive destination for individuals seeking reliable, safe, and lasting vision correction.
International patients often highlight the convenience of the clinic’s structured care system, which includes pre-surgery counseling, interpreter services, and transparent discussions of Smile Lasik cost and price. The overall experience is designed to make patients feel secure and supported throughout their journey to visual freedom.
For anyone considering SMILE PRO as a solution for myopia or astigmatism, SNU Eye Clinic offers one of the most advanced platforms available. More details about the clinic, its surgical techniques, and patient services can be found at snuseoul.com.
