Line up the eye
CenTrax measures cyclotorsion, the slight rotation of the eye, and corrects docking error.
Smart Nova LASIK in Korea
New SMILE, with docking errors corrected
Smart Nova LASIK is New SMILE LASIK with the CenTrax treatment mode added. CenTrax corrects eye rotation and docking error that can appear or remain while the laser attaches to your eye.
The tissue still leaves through a 2mm opening, and no flap is made. What changes is how precisely the laser lines up.
Docking
Why docking matters
Docking is the moment the laser attaches to your eye. Small errors can creep in at this stage, or stay behind. CenTrax measures them and compensates, which is why the clinic calls the procedure safer and more accurate.
The procedure runs on the ATOS Nova Centrax laser, listed on the equipment page. If you want the same operation without CenTrax, read New SMILE LASIK.
Procedure
Four steps
Shape the lenticule
The ATOS laser cuts a lens-shaped piece of tissue, the lenticule, inside the cornea.
Open 2mm
A very small opening is made on the corneal surface.
Remove the tissue
The surgeon draws the lenticule out through that opening. No large flap is created.
Equipment
What the system adds
- Automatic center correction: after docking, CenTrax keeps correcting eye movement to offset errors that could otherwise remain.
- Lower energy: low pulse energy and an asymmetric spot pattern put less energy into the cornea, which supports recovery.
- Finer steps: refraction is entered in 0.05D units for individual correction.
- Biometry link: the laser connects automatically to ocular biometry equipment, so the plan reflects your own eye.
- Pressure control: the clinic lists prevention of an excessive rise in eye pressure among the features.
- Speed: a 4MHz laser with an improved lenticule design.
Who It Suits
When the clinic suggests it
One or more of these
- You want surgery that is more precise and safer.
- Residual prescription or halos after surgery concern you.
- Your myopia is high and your cornea is thin.
- You worry about pain or side effects afterwards.
- You want vision to return quickly.
- You need accurate astigmatism correction.
Exam First
Suitability is a medical decision
Preparation rules, including when to stop wearing contact lenses, are in the pre and post-op guide. Fees are listed under Smart Nova LASIK cost in Korea. For international patients, the clinic lists fees at 49% off the regular rate, the same fee Korean patients pay, and adds a free MRI precision exam (worth KRW 100,000) and free autologous serum eye drops (worth KRW 200,000).
FAQ
Common questions
How is Smart Nova different from New SMILE LASIK?
It adds CenTrax, which corrects eye rotation and docking error. The system also takes refraction in finer 0.05D steps and links automatically to biometry data.
What exactly does CenTrax correct?
Cyclotorsion and docking error. It automatically adjusts for eye movement and offsets residual errors that can occur or remain during docking.
How large is the incision?
2mm. The corneal tissue is removed through that opening on the surface.
Who is it usually recommended for?
People concerned about residual prescription, halos, pain or side effects, people with high myopia and thin corneas, and those who need precise astigmatism correction. Your exam confirms it.
