New SMILE Pro Differences | How Does It Differ from Existing New SMILE LASIK?
Confused by similar terms like SMILE Pro, New SMILE, and New SMILE Pro? This article clarifies the differences between 5th-generation LASIK procedures, including New SMILE LASIK, SMILE Pro, and the advanced New SMILE Pro, highlighting its enhanced centering accuracy and prescription precision.


Hello, this is Gangnam SMILE Eye Clinic 😊💙
When researching vision correction surgery recently,
many people get confused by similar terms like
SMILE Pro, New SMILE, and New SMILE Pro.
Today, we will compare and explain three surgeries:
✔SMILE Pro and ✔New SMILE, which emerged after 4th-generation SMILE LASIK as 5th-generation LASIK,
and ✔New SMILE Pro, which is an even more upgraded version.
LASIK Surgery Generation Overview
Vision correction surgery is much easier to understand
when categorized by generation according to technological advancements.
1st Generation LASIK) Blade LASIK

This was an early LASIK procedure where a large corneal flap was created,
and vision was corrected with an excimer laser.
At this time, because the corneal flap was made with a blade,
there was a high risk of corneal damage, and it was vulnerable to dry eyes and external impact.
You can consider this surgery to be almost entirely phased out now.
2nd Generation LASIK) Laser LASIK
This method compensated for the shortcomings of the 1st generation,
with more refined corneal flap creation technology.
However, the corneal flap was still large,
and there was a limitation of significant corneal structural changes.
3rd Generation LASIK) LASEK Series (PRP)
This method corrects vision without creating a flap,
by completely removing the corneal epithelium.
While it is resistant to external impact because no flap is made,
it involves pain as the epithelium needs to heal,
and the recovery period is relatively long.
4th Generation LASIK) SMILE LASIK
What emerged next was SMILE LASIK.
SMILE LASIK is structurally stable as it is a flapless method,
and it also minimizes corneal incision,
resulting in faster recovery and less pain.
5th Generation LASIK) New SMILE LASIK, SMILE Pro
After SMILE LASIK,
surgeries that further enhanced precision and stability emerged.
✔ New SMILE LASIK
✔ SMILE Pro
These two surgeries can be seen as upgraded 5th-generation LASIK
following SMILE.
5th Generation LASIK Upgrade: New SMILE Pro Differences

And what has recently emerged
is New SMILE Pro.
Based on the existing New SMILE LASIK,
it upgrades the NOVA Smart Sight technology
to enhance centering accuracy and prescription precision,
thereby strengthening stability.
In other words,
New SMILE Pro can be seen as the complete upgraded version of 5th-generation LASIK.
What are the differences between New SMILE and New SMILE Pro?

Automated Centering Correction Technology


The biggest advantage and core feature of New SMILE Pro is
its upgraded centering technology.
It automatically corrects issues where the center shifts during the docking process,
when the machine is brought into close contact with the eye during surgery.
Therefore, it is particularly advantageous for patients with high astigmatism, where accurate centering is crucial,
and for patients who are nervous or tend to move their eyes easily.
This automates what previously required manual adjustment
in existing SMILE Pro or SMILE procedures.
Thanks to this technology, the influence of external factors (such as medical staff, patient cooperation, etc.)
is minimized, allowing for accurate vision correction and stable results.
Prescription Precision
Another difference in New SMILE Pro is that it
analyzes the cornea and eye condition more precisely,
and has refined the prescription input from 0.25D units to 0.05D units,
making it 5 times more precise.
This means that the precision has improved by 5 times compared to existing methods,
minimizing residual refractive errors.
In other words, customized vision correction perfectly suited to the patient's eyes has become possible.
Pre-operative Energy Delivery Prediction
Furthermore, New SMILE Pro predicts laser energy delivery in real-time
during the pre-operative docking stage.
This allows for precise laser settings tailored to the corneal condition
and prevents excessive energy exposure,
minimizing the risk of tissue damage.
Therefore,
it ensures both ‘safety’ and ‘stability’
simultaneously.
Patients Suitable for New SMILE Pro

Patients with high astigmatism - accurate correction with automated centering technology
Patients who are anxious about surgery - enhanced docking stability
Patients who find traditional LASIK surgery burdensome - improved safety and predictability

New SMILE Pro is not just a new name for a surgery,
but a complete, upgraded version of 5th-generation LASIK technology.
It surpasses existing surgeries in terms of centering accuracy, customized design, and stability,
making it the latest SMILE LASIK especially recommended for patients with high astigmatism or those who find docking difficult.
New SMILE Pro, Why Gangnam SMILE?


✔ Open operating room where guardians can directly observe the surgical process through a glass structure
✔ Non-factory type hospital focusing on personalized treatment and surgery for each patient
✔ New SMILE LASIK: Most surgeries for 4 consecutive years, with stable results from extensive clinical experience
New SMILE Pro and Gangnam SMILE Eye Clinic, equipped with safety, precision, and customized vision correction,
are the most reliable ‘choice’.

SMILE Pro differences
Frequently Asked Questions
What is the difference between New SMILE Pro and existing SMILE LASIK?
New SMILE Pro is an upgraded version of 5th-generation LASIK, with improved centering accuracy and diopter precision compared to existing SMILE LASIK. Specifically, it features automatic centering correction technology and fine diopter adjustment in 0.05D increments.
What is the biggest advantage of New SMILE Pro?
The biggest advantage of New SMILE Pro is its automatic centering correction technology. It automatically corrects any centering misalignment that may occur during the docking process of the surgery, providing accurate vision correction and stable results.
Which patients are suitable for New SMILE Pro?
New SMILE Pro is particularly suitable for patients with high astigmatism requiring precise correction, patients with significant fear of surgery, and those who found traditional LASIK surgery burdensome. It offers enhanced safety and predictability.
How precise is the diopter adjustment in New SMILE Pro?
New SMILE Pro allows for fine diopter adjustment in 0.05D increments, which is 5 times more precise than the existing 0.25D increments. This enables customized vision correction perfectly suited to the patient's eyes, minimizing residual refractive errors.
What are the safety features of New SMILE Pro?
Yes, New SMILE Pro has several features to ensure safety. During the pre-surgical docking phase, it predicts the laser energy delivery in real-time, allowing for precise laser settings tailored to the corneal condition, and minimizes the risk of tissue damage by preventing excessive energy exposure.
