Gangnam Station Eye Clinic: Smart LASIK Differences (Feat. What is New SMILE LASIK?)
Discover the differences between SMILE LASIK and Smart LASIK at Gangnam Station Eye Clinic. Learn about the advanced 5th-generation Smart LASIK (New SMILE LASIK) and its benefits for precise astigmatism correction and faster recovery.


Hello, this is Gangnam Smile Eye Clinic at Gangnam Station 😊💙
If you've experienced discomfort wearing glasses or contact lenses due to poor eyesight, you've probably considered vision correction surgery like LASIK or LASEK at some point.
Recently, ‘Smart LASIK (New SMILE LASIK)’ has been gaining attention for being more precise, having faster recovery, and fewer side effects than existing surgical methods.
But what exactly is the difference between SMILE LASIK and Smart LASIK, which have similar names?
Today, at Gangnam Station Eye Clinic, we'll clearly explain the features of Smart LASIK and how it differs from existing vision correction surgeries.
What is Smart LASIK? Smart LASIK Differences

Smart LASIK (New SMILE LASIK) is a 5th-generation vision correction surgery based on the advanced laser equipment ATOS and precise diagnostic equipment SIRIUS from SCHWIND, Germany.
SCHWIND is the company that developed Amaris Red (Today LASEK equipment), which holds a unique advantage in excimer laser equipment used for traditional LASIK and LASEK surgeries.
Smart LASIK is based on the 4th-generation vision correction method, SMILE LASIK, and utilizes SCHWIND's robust technology to maintain a smoother ablation surface than existing SMILE LASIK through low energy.
Combined with 7-dimensional eye-tracking technology, it can detect and reflect even minute tremors or movements of the eye that may occur during surgery in real-time, allowing for more precise and stable surgical results.
It is particularly excellent for astigmatism correction, minimizing the incision area for faster recovery and less strain on the eyes.
Gangnam Station Eye Clinic LASIK Astigmatism Correction

The biggest advantage of Smart LASIK is the precision of astigmatism correction.
A common oversight when correcting astigmatism is ocular cyclotorsion.
If the eye's position changes between the pre-operative examination and the actual surgery, the astigmatism axis can be slightly misaligned.
This small difference significantly impacts the accuracy of astigmatism correction.
The ATOS equipment tracks eye movements in real-time during surgery and precisely corrects rotational errors.
This means accurate correction is possible even in challenging cases like high astigmatism.

Furthermore, if the pupil center and visual axis do not align during surgery, the surgical effect may be reduced if the laser is not accurately positioned.
Smart LASIK uses the SIRIUS equipment to precisely analyze the visual axis and pupil center in 3D, finding and correcting to the ideal laser irradiation position (Sweet Spot) for each individual's eye.
In other words, while existing surgeries corrected based on general standards, Smart LASIK can be seen as a customized surgery tailored to each individual's eyes.
Therefore, Smart LASIK (New SMILE LASIK) allows for stable and accurate correction tailored to individual eyes.
Gangnam Smile Eye Clinic already possesses objectively verified results in this area.

Gangnam Smile Eye Clinic, located at Gangnam Station, published a clinical paper on the accuracy of astigmatism correction after Smart LASIK using ATOS, demonstrating that 99% of patients achieved their target vision.
This result is not just marketing; it represents a medically recognized, data-driven success rate for vision correction.

✅This indicates not just simple vision recovery but successful precise correction of refractive errors.
✅It means there was almost no discrepancy between the target vision planned before surgery and the actual vision.
✅This result proves the stability of the Smart LASIK + SIRIUS system.
However, these results are not achieved by good equipment alone.
They are possible thanks to accurate analysis, meticulous surgical planning, and 1:1 personalized care.
Gangnam Smile Eye Clinic performs dozens of precise examinations for all patients before surgery and adheres to a 1:1 personalized system where the assigned specialist is responsible from beginning to end.


At Gangnam Smile Eye Clinic, various precise examinations, including SIRIUS, Pentacam, OCT, and corneal topography, are thoroughly conducted before Smart LASIK surgery to ensure a safe procedure.
Furthermore, we consider each patient's eye condition and lifestyle to recommend the most suitable vision correction surgery.
