What is SMILE Pro? A Complete Guide to Differences from SMILE LASIK & Selection Criteria

Everything About Advanced Vision Correction Upgraded with VisuMax 800

Hello. This is BGN Eye Clinic at Jamsil Lotte Tower.

SMILE Pro is the latest vision correction procedure developed based on the core principles of traditional SMILE LASIK. While utilizing the same underlying surgical method; the lenticule extraction technique, it offers significant advancements in equipment, laser speed, and precision calibration technology.

At BGN Eye Clinic Jamsil, we perform procedures using the specialized SMILE Pro equipment, the VisuMax 800.

How Does SMILE Pro Differ from Traditional SMILE LASIK?

Compared to the VisuMax 500 used in traditional SMILE LASIK, SMILE Pro features enhanced laser delivery speed and advanced eye-tracking compensation technology. Rather than changing the surgical principle itself, it is most accurate to understand SMILE Pro as an upgraded version engineered for greater technical precision and speed.

3 Core Technologies of SMILE Pro

1. Faster Laser Delivery Speed

SMILE Pro significantly increases laser delivery speed compared to previous generation equipment. By reducing the time required to create the corneal lenticule, the eye fixation time is shortened, helping to alleviate physical and mental pressure during surgery. Faster surgery is not merely a matter of convenience; it also serves as a positive factor in minimizing the possibility of subtle eye movements during the procedure.

2. Oculign® – Astigmatism Alignment Precision

When lying down, a person's eyes can undergo subtle rotational shifts. Oculign® is an automated system that detects and compensates for these cyclotorsional movements. This feature plays a vital role in enhancing the accuracy of astigmatism correction. Because angular errors can significantly impact visual quality when astigmatism is present, this precision compensation technology serves as a cornerstone of the procedure.

3. CentraLign® – Center Alignment Technology

CentraLign® is a technology designed to align the center of the cornea with higher precision. It ensures that the central axis of laser delivery remains stable, effectively reducing potential surgical margins of error. This demonstrates that SMILE Pro has evolved not just to be a "fast surgery," but to significantly elevate alignment accuracy.

The key takeaway is that the fundamental surgical methodology remains the same. Therefore, rather than viewing it as a "completely different surgery," it is most appropriate to understand SMILE Pro as an enhanced evolution in terms of safety and technical precision.

Who is SMILE Pro Suitable For?

You may want to consider SMILE Pro if you:

  • Have astigmatism
  • Prioritize high-precision visual outcomes
  • Feel anxious about eye fixation time during surgery
  • Prefer procedures based on the latest generation equipment

However, SMILE Pro is not strictly necessary for every candidate. The ideal correction method varies depending on individual factors such as corneal thickness, degree of myopia/astigmatism, and overall ocular anatomy. At BGN Eye Clinic Jamsil, we conduct comprehensive pre-operative examinations to determine whether SMILE Pro is the right fit for your eyes.

What Matters in SMILE Pro is 'Data', Not Just 'Equipment'

While technological advancement is central to SMILE Pro, surgical outcomes are not determined by equipment alone. Stable, reliable results require a combination of surgical expertise, extensive clinical data, and an organized post-operative care system. A data-driven surgical strategy setting tailored correction values based on comprehensive clinical records is essential.

SMILE Pro at BGN Eye Clinic Jamsil

Since early adopting SMILE LASIK, BGN Eye Clinic Jamsil has continuously upgraded its technology and accumulated extensive clinical data. Our SMILE Pro procedure is systematically conducted through the following stages:

  1. Corneal Thickness & Topography Analysis
  2. Precision Astigmatism Axis Analysis
  3. Ocular Center Alignment Verification
  4. Personalized Surgical Planning
  5. Post-Operative Follow-Up Management

It is not just about possessing the latest SMILE Pro equipment; the entire end-to-end framework from diagnostics and planning to surgery and post-operative care is what truly defines quality outcomes.

Essential Checklist Before Choosing SMILE Pro

If you are considering SMILE Pro, we recommend evaluating the following factors:

  • The medical institution's overall experience with SMILE procedures
  • Track record in complex astigmatism correction cases
  • Availability of advanced, high-precision diagnostic systems
  • Structured post-operative care protocols

SMILE Pro represents a major technological step forward, but individual anatomical variations exist in every surgical case. The most critical step is to determine candidacy through thorough consultation and diagnostics.

In summary, SMILE Pro is an advanced vision correction procedure that preserves the fundamental principle of SMILE LASIK while enhancing laser speed, astigmatism correction, and center alignment technology. Its biggest advantage lies in elevated precision and surgical stability.

At BGN Eye Clinic Jamsil, we provide personalized guidance on the most suitable vision correction method based on thorough pre-operative testing. If you are considering SMILE Pro, look beyond the equipment name and evaluate whether it is truly the best fit for your eyes.
