Smooth Incision Lenticular Keratomileusis

Experience highly refined vision correction
with SILK, powered by the
Johnson &Johnson Vision
ELITA™ laser—delivering silk-smooth
precision through ultra-low energy pulses.

Bi-Convex Lenticule

Bi-convex (Double-Convex) Lenticule

Clear Vision / Reduced Glare

Matching anterior and posterior lenticule curvatures
minimize corneal wrinkling, ensuring a smoother
interface and more consistent,
high-quality 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

Preservation of Corneal Strength

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

Add eye fixed suction ring

Unlike conventional surgery, the eye is fixed
with a suction ring. Risk of suction loosening and
preventing errors due to eye movement

Visual Axis and
Astigmatism Axis Alignment
in Silk Surgery

Centering / Astigmatism Axis Correction

After docking, the central axis and
astigmatism rotational axis
are reset to prevent visual axis deviation and
astigmatism axis errors.

1μm Ultra-Micro Laser Spots
with Low-Energy Pulses

Unlike conventional surgery, the eye is fixed
with a suction ring. Risk of suction loosening and
preventing errors due to eye movement

Conventional Laser Spots

SILK LASIK Laser Spots

It's a 1µm spot size that's less than half of the existing laser
40nJ pulse energy for a smoother and more uniform lenticular
incision It forms and implements high vision 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

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.

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.

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.

Nerve damage by corneal flap making

Passes through the corneal nerve layer and creates a lenticle in the middle layer of cornea(maintains the corneal nerve)
