Femto LASIK at the LZW:
safe and painless
Before a defective vision can be corrected with LASIK, the corneal flap must be prepared. For this we use the femtosecond laser (instead of the mechanical cutting tool, the microkeratome), an advanced and highly accurate laser. The procedure is very safe, painless and faster than the traditional LASIK. Femto lasers work without any heat development.
First the flap, then the LASIK
Once the flap has been prepared, the actual LASIK procedure is carried out. No matter whether Femto or traditional LASIK is used, with an excimer laser one thousandth of a millimetre of corneal tissue is removed. The cornea is modelled, the defective vision corrected. After the surgery, the flap is folded back again. It adheres by itself and protects the wound like a natural dressing. The procedure is virtually painless.
For anxious patients, we also offer this laser procedure with a short-term anaesthetic.
By the way: LASIK (acronym for laser-assisted in situ keratomileusis) has become the world’s most successfully performed technology for the treatment of vision defects. In Germany alone, more than 100,000 people have LASIK surgery each year.
Preparation of the flap with the femtosecond laser:
First, a thin flap is created in the top layer of the cornea. Then the Femtolaser is used to send ultra-short laser impulses to below the surface of the cornea. The result is a flap that is precisely shaped, down to a hundredth of a millimetre. The flap is folded to the side – and the eye is ready for the LASIK procedure.
LASIK – corneal reshaping with the excimer laser:
Now, the curvature of the cornea is reshaped according to the original diagnosis. This will only take a few seconds. The flap is carefully repositioned over the treatment area. This protects the eye like a band-aid and will adhere within a short time.
