SLIK LASIK
Smooth Incision Lenticular Keratomileusis
A highly refined vision correction surgery using
low-energy ELITA laser SILK technology developed by
Johnson & Johnson in the U.S., delivering
smooth SILK-like incision surfaces
Bi-Convex Lenticule
Consistent Visual Clarity
The matching anterior and posterior curvature of the lenticule reduces corneal wrinkling after removal, resulting in a smoother interface and more consistent visual recovery
Reduced Risk of Dry Eye
Unlike conventional lenticules, the lenticule is formed deeper in the posterior corneal layer, minimizing damage to corneal nerves. This allows faster nerve regeneration and lowers the incidence of dry eye symptoms
Reduced Halos and Glare
The symmetrical front and back surfaces of the lenticule help maintain corneal biomechanics and contribute to preserving corneal optical quality, which reduces halos and light scatter.
Precise Pupil Alignment and
Astigmatism Axis Correction
in SILK Surgery
Real-time Pupil Centering
Prevents axis deviation by continuously tracking and
maintaining the pupil center after docking
Astigmatism Axis control
During Surgery
Prevents misalignment caused by eye rotation,
reducing residual astigmatism and minimizing
higher-order aberrations
Low-Energy Pulses with
1μm Ultra-Micro Laser Spots
In femtosecond laser surgery, the size of the laser spot,
pulse energy, and repetition speed greatly
influence surgical quality.
Conventional Laser Spots
High laser energy increases the risk of surrounding tissue damage
and results in a rougher incision surface
SILK LASIK Laser Spots
Low laser energy reduces surrounding tissue damage and creates
a smoother incision surface
ELITA (SILK) uses an average laser spot spacing of 1μm, minimizing tissue bridges and cavitation bubbles after cutting.
This produces a smoother, more uniform corneal lenticule interface, delivering higher visual quality
Solution 01
AcuTarget visual axis analysis
AcuTarget SMILE
Next generation laser vision correction surgery with amazing recovery speed and excellent safety
Corneal center No.! Pupil Center No.!
Correction with more precise Purkinje center (Optical Zone Center)
AcuTarget is a visual axis analysis device, and in JOEUNNUN VISION CLINIC, you can obtain higher quality vision by performing SMILE surgery based on precise visual axis analysis using AcuTarget.
Solution 02
Next generation vision correction surgery using Avedro KXL system
Prevents the cornea weakening in SMILE surgery
Strengthens the cornea with collagen cross-linking
Riboflavin (vitamin B2) solution is applied to the site where the lenticle has been removed.
Riboflavin solution is absorbed into corneal tissue.
Ultraviolet A(UVA) is irradiated on the cornea for approximately 30~60 seconds.
With the increase of cross-linking in the collagen fiber, the corneal strength is restored again.
Corneal cross linking using the Avedro KXL system and VibeX,a riboflavin solution, induces collagen cross-linking that com-poses the cornea, thereby increasing the strength of thecornea.
Solution 03
Personalized energy
for satisfactory surgical results
Appropriate use of energy according to the characteristics of each individual corneal tissue!
In the case of excessively large laser energy, there is a possibility of damage to the surrounding tissue. Conversely, if the energy is too low, it may lead to even severe damage to the corneal tissue due toincomplete separation of the corneal flap.
In SMILE Surgery, the cornea is separated with a Femtoseconds Lasers
If corneal separation is incomplete due to too low laser energy, this can cause damage to the surrounding cornea.
Therefore, when the appropriate energy is used for the characteristics of each individual’s corneal tissue, the separated corneal surface is the smoothest, and stable surgical results can be obtained.
Solution 04
Less postoperative side effects by reducing corneal nerve damage!
Prevention of corneal nerve damage
In LASIK and LASEK, the upper layer of the cornea is cut, which leads to damage to the nerve layer and causes sensory changes in the cornea and dry eye.
SMILE surgery has little to no corneal sensory change because the corneal nerve is less damaged.
