“ Reasons to get CLEAR LASIK ”


Removal of corneal stromal lenticule2mm micro-incisionBorn from combining the strengths of LASIK and LASEK. Beyond SMILE — the 4th-generation refractive surgery, Clear SMILE LASIK.
Using the special laser of Swiss
Ziemer's FEMTO LDV Z8,
the procedure passes through the corneal surface to shape a lenticule
inside the stromal layer, then extracts it through a 2mm micro-incision
to correct refractive errors.
Low energy & faster speed for safer surgery

The Z8 low-energy laser shapes a lenticule in the corneal stroma.

A minimal 2mm incision is made on the cornea.

The lenticule is extracted through the previously created channel.

Why Clear SMILE is special — 2
Accurate astigmatism correction & reduced glare

With the upgraded interface, centration can be adjusted even after docking. The lenticule is shaped with cyclotorsion-induced error factored in, enabling precise astigmatism correction, while mitigating the glare that such error may cause.
Why Clear SMILE is special — 3
Safer lenticule removal
Real-time high-resolution OCT verifies the surgical area and both the front and rear surfaces of the lenticule, enabling more precise and safer extraction.

Very low suction-loss probability


Unlike conventional systems where the device clamps to the eye under high pressure, the improved docking system markedly reduces the chance of suction loss caused by eye tremor or movement during surgery.

Note: Post-operative outcomes can include night glare, dry eye, myopic regression or keratoconus depending on individual condition. Please consult with a specialist before deciding.
