COMPARISON OF THE DIFFERENT OPERATING TECHNIQUES

PRK/TransPRK

The eye is first anaesthetised by applying eye drops. Then, the outer surface of the cornea is abraded by a laser or mechanically over about 50 microns. Then, the Excimer laser is applied to the stromal surface of the cornea. At the end of the operation, the surgeon applies a therapeutic bandage lens.

Femto LASIK

First, the surgeon anaesthetises the eye by applying eye drops. Then, a thin surface layer of cornea, called the flap, about 100 microns thick, will be created. It allows the surgeon to perform corrective treatment on a deeper and more homogeneous area of the cornea, the stroma. The corneal flap is then repositioned.

SMILE

First, the eye is anaesthetised by applying eye drops. The surgeon then applies the corrective treatment directly into the thickness of the stroma without cutting or surface abrasion of the cornea. Finally, the surgeon mechanically removes the cut tissue through a small incision.

PRK/TransPRK

5 to 10 minutes per eye.

Femto LASIK

Both eyes are operated in 6 minutes.

SMILE

Both eyes are operated in minutes.

PRK/TransPRK

Pain and burning sensation for 2 to 6 days

Femto LASIK

No pain

SMILE

No pain

PRK/TransPRK

7 days to 1 month

Femto LASIK

2 to 3 hours after (evening or the next day). You can return to work the next day

SMILE

48h to 72h

PRK/TransPRK

• Lower Cost

Femto LASIK

• Very fast visual recovery
• Painless
• Treatment of both eyes at the same time
• The most effective technique in terms of visual quality, especially with regard to the treatment of presbyopia and hypermetropia
• Approved process with 20 years of technological backing
• Very simple and fast re-correction

SMILE

• Painless
• Treatment of both eyes at the same time

PRK/TransPRK

Post operative pain between 48H to 7 days

Femto LASIK

Requires a minimum corneal thickness of 500 microns.

SMILE

Re-correction is impossible with this method. It is also impossible to treat hypermetropia, presbyopia and excessive astigmatism.
