BGN Eye Clinic SMILE Pro: How Does It Differ from Traditional SMILE?

Hello, this is BGN Eye Clinic at Jamsil Lotte Tower.

When considering vision correction surgery, recovery speed and the procedural approach are usually top priorities for most patients. In particular, working professionals in their 20s and 30s who require a quick return to their daily routines have shown a growing interest in SMILE Pro.

• What SMILE Pro is
• Key differences from traditional SMILE
• Essential criteria for choosing an eye clinic

In this article, we have compiled the essential information to help guide those who are evaluating vision correction options.


1. What is SMILE Pro?

SMILE Pro is an advanced vision correction procedure that creates a thin lens-shaped tissue (lenticule) inside the cornea without creating a corneal flap, which is then gently extracted through a microscopic incision.

"A Technologically Refined Evolution of Traditional SMILE"
While maintaining the core mechanism of conventional SMILE, SMILE Pro integrates the following technological enhancements:

• Significantly faster laser delivery speed
• Upgraded visual axis alignment and tracking system

These advancements contribute to enhanced procedural efficiency and surgical precision. Consequently, inquiries regarding SMILE Pro at BGN Eye Clinic have been steadily increasing.

*Suitability for the procedure may vary depending on individual ocular characteristics.


2. The SMILE Pro Surgical Process at BGN Eye Clinic

The SMILE Pro procedure at BGN Eye Clinic follows these key steps:

① Pre-operative Precision Examination
We perform over 60 comprehensive tests including corneal thickness, corneal topography, astigmatism axis, and pupil size to evaluate candidacy and determine the optimal correction method. The emphasis here is on thorough individual analysis rather than pushing unnecessary procedures.

② Intra-corneal Lenticule Creation
Utilizing Carl Zeiss's advanced SMILE Pro laser system, a precise lenticule is formed within the corneal layers.

③ Micro-incision and Lenticule Extraction
Without making a large flap, the doctor extracts the lenticule through a tiny micro-incision of approximately 2 mm to achieve vision correction.

④ Recovery Phase
Many patients plan to return to normal daily activities as early as the next day, though actual recovery rates and personal experience may vary based on individual eye conditions.


3. SMILE Pro vs. Traditional SMILE: A Quick Comparison

While both procedures share the benefit of flapless surgery, SMILE Pro stands out with its reduced laser duration and advanced alignment tracking capabilities.

CategoryTraditional SMILESMILE Pro
Laser DurationApprox. 24 secondsApprox. 8 seconds
Incision Size2–4 mmApprox. 2 mm
TechnologyCustomized energy deliveryEnhanced visual axis & pupil alignment tracking
Correction ScopeMyopia to High MyopiaHigh Myopia / High Astigmatism coverage
With reduced laser delivery time and enhanced visual axis alignment, SMILE Pro is recognized for broadening treatment applicability to challenging high astigmatism cases.


4. Why SMILE Pro is Gaining Attention

The interest in SMILE Pro extends beyond mere speed; it incorporates key technologies that significantly elevate surgical precision.

• Central Line: Assists with real-time center alignment based on the visual axis during surgery, supporting a more stable correction process.
• Ocu-Line: Automatically compensates for subtle cyclotorsion (eye rotation) that occurs when lying down, enhancing surgical accuracy.
• Expanded Astigmatism Scope: Enables highly precise treatment even for patients with high astigmatism or a notable deviation between the visual axis and pupil center.


5. Is SMILE Pro Right for Everyone?

Despite advancements in technology, no single vision correction method is universally perfect for every individual. Depending on factors like corneal thickness, astigmatism severity, pupil size, and structural eye characteristics, alternative treatments such as LASIK or LASEK may remain the superior choice.

Therefore, decisions should not rely solely on general praise for SMILE Pro; an objective medical examination and professional evaluation must come first.


6. We Prioritize a Rigorous Evaluation Process

Vision correction surgery is completed not merely by introducing state-of-the-art equipment, but through the clinical expertise of medical professionals and meticulous analysis of each patient's ocular profile.

Building upon years of accumulated experience in vision correction, BGN Eye Clinic thoroughly analyzes corneal characteristics to collaborate on finding the most suitable path for each patient. We encourage you to make an informed decision after gaining a clear understanding of your eye health through comprehensive examinations and consultation.
