range

Less pain · Fast recovery
A gentle, minimally invasive procedure that creates a tiny lenticule within the
corneal stroma and removes it through a micro-incision.
This smaller incision speeds up recovery and enhances not just how well you see — but how clearly.
The result? A high level of satisfaction among today’s vision-conscious patients.
Why do some hesitate about SMILE surgery,
despite its fast recovery and minimal
pain?
Potential concerns: dry eye syndrome, glare/halo effects, and myopia regression
In today's world, quick and low-discomfort procedures have become the norm.
But what truly matters is
Satisfaction with your vision — for life.
Restoring the eye to its most natural, ideal state

Johnson & Johnson — a global leader in vision correction
Silk Smile, built on 140 years of innovation and a patient-centered philosophy
Advanced core technologies,
engineered to minimize side effects
1. Biconvex lenticule optimized
for better post-surgical recovery
2. The world's smoothest and gentlest laser
New Lenticule Design for Smoother, Clearer Vision
Perfect vertical symmetry Bi-convex design
The shape of the lenticule and the consistency of corneal healing
result in not just better visual acuity, but a higher quality of vision
overall.

Bi-convex (lens-shaped) lenticule
In conventional SMILE surgery, the lenticule’s upper and lower surfaces are asymmetrical, which can lead to misaligned incision planes after removal. As a result, subtle wrinkles may form during healing — potentially affecting visual clarity and contrast sensitivity.
Why clear vision is maintained even in dark environments
Lenticule bonding surface that becomes as smooth as silk without wrinkles
When there are wrinkles between corneal stromal layers
Wrinkles scatter light,
leading to blurry vision and poor image clarity.
When there are no wrinkles between corneal stromal layers
Light passes cleanly through the cornea, focusing sharply on the
retina
for crisp, clear vision with minimal distortion.
Next-generation laser technology for smoother lenticule formation and precision extraction
World’s lowest thermal energy · Smallest beam size · Densest spot spacing
Point 1.
Lowest energy among existing lasers
The Elita laser irradiates with minimum 40nJ of energy, reducing
thermal damage
to corneal tissue compared to existing SMILE surgery. As a result,
the risk of side effects and complications that may occur after surgery
has decreased.
Point 2.
Minimum size laser beam
It is equipped with the laser with the smallest beam size among
existing vision correction laser equipment.
Therefore, it can cut corneal stroma more precisely
and minimize damage to surrounding tissues.
Recovery is so fast that daily life is possible the day after
surgery,
and various side effects can be prevented.
Point 3.
Dense spacing between laser spots
In vision correction surgery, the spacing between laser spots
greatly affects the quality of vision.
If the distance between spots is too far, the lenticule is not properly cut,
requiring physical tearing during separation, which can degrade vision quality after
surgery.
Conversely, if spots are irradiated with excessive overlap,
the resulting bubbles can interfere with the next spot, making accurate
lenticule formation difficult.
Why lenticules should be created deep in the cornea
Protecting corneal nerves to reduce dry eye symptoms
Relief from dry eye syndrome through corneal nerve protection
Numerous corneal nerves that control tear secretion exist in the upper cornea.
If these nerves are cut or damaged during surgery, tear production decreases,
which can cause dry eye syndrome.
Silk Smile LASIK creates lenticules deep in the cornea,
minimizing corneal nerve damage.
Preventing myopia regression by creating lenticules deep in the cornea
The central cornea is denser and more rigid the closer it is to the surface.
By forming the lenticule deeper in the corneal stroma, Silk Smile surgery preserves the upper
corneal structure, reduces tissue damage, and enhances surgical stability.
This deeper approach also helps lower the risk of myopia regression
and provides better protection against external trauma.
The most precise physical adhesion —
Advanced Docking System
Point 1.
Post-docking correction system
Ensures higher docking success rates with a built-in adjustment system after initial docking.
This feature allows for precise alignment of the central and astigmatic axes, ensuring accurate and stable laser delivery.
Point 2.
Perfect adhesion without gaps
The flat docking interface is designed to accommodate each patient’s unique corneal curvature.
Unlike traditional curved designs, this flat structure ensures complete, uniform contact with the eye — without any gaps.
This also helps prevent suction loss during surgery, improving safety and consistency.
