Femto Lasik is a two step procedure involving two lasers. First, the surgeon creates a small flap in the cornea to prepare the eye for the next step, the vision correction.
The traditional LASIK method of laser vision correction requires a mechanical blade to make the flap.
However, in FEMTOLASIK method we create the flap using the FEMTO LDV™ femtosecond laser. It makes the whole procedure completely bladefree and enables the surgeon to tailor the procedure according to the very unique characteristics of every patient. A truly personalized treatment for everybody!
Never before have safety, accuracy and patient comfort in laser eye surgery been so good, as proven by many thousands of FEMTOLASIK treatments.
Femto Lasik Adventages:
FEMTOLASIK has an extremely low impact on the eye:
The procedure takes only a few minutes. The time the laser is in contact with the patient’s eye is reduced to a minimum.
FEMTOLASIK is comfortable and painless: The patient’s head is not fixed during the procedure.
FEMTOLASIK also helps in severe cases: Thanks to the extremely high frequency of the laser pulses, the layers of the cornea are separated with unprecedented precision, creating an ultra-thin flap. FEMTOLASIK is therefore effective in patients who were previously not candidates for laser surgery. This includes patients with extreme myopia or thin corneas.
No inflammation: The laser energy used for FEMTOLASIK is about a 100 times lower than with other lasers. This is more gentle to the corneal tissue and prevents temporary inflammatory reactions of the eye.
Fast results: The recovery period is considerably shorter than for other techniques. Patients are usually able to see well within hours, often even minutes.
Fewer side effects: FEMTOLASIK enables the surgeon to enlarge the treatment zone. This reduces the risk of undesirable side effects such as dry eyes, deteriorated night vision or haloes (rings of light that surround point sources of light).
Femto Lasik Range of application
FEMTOLASIK is suitable for correcting the following refractive errors:
- Myopia: Distant objects appear blurred.
- Hyperopia: Closed objects appear blurred.
- Astigmatism: Objects appear distorted at all distances.
- Presbyopia: The lens of the eye loses its ability to focus, making it difficult to see objects up close.
Femto Lasik procedure:
Step 1: Pre-operative Exam
Your physician performs a series of tests to ensure that your eyes are healthy and suitable for laser vision correction. Then, your eye is electronically measured in detail: Thousands of data points are surveyed to create an accurate three-dimensional image of your eye’s surface. From this image, the computer calculates the laser treatment that will best correct your refractive error.
Step 2: Flap Creation with the FEMTO LDV femtosecond laser
A few minutes before the laser treatment, you are given anaesthetic eye drops. Next, your eye is prepared for the correction itself by creating the corneal flap: The top layer of the cornea (approx. 0.1 mm thin) is separated with the laser and folded back.
Step 3: Corneal Correction
Now the curvature of the cornea is reshaped according to the desired refraction. An excimer laser ablates corneal tissue within seconds and precisely to the hundredth of a millimeter. This procedure is performed inside the cornea; the outer, very sensitive layers of the cornea are not touched by the laser. Finally, the treated area is recovered with the flap that grows back quickly. The whole procedure takes only a couple of minutes. Immediately after treatment, you can open and close your eye normally.
Step 4: Easy Aftercare
If necessary, your operative eye is protected with a contact lens for one day. Special eye drops promote healing. During the first few hours after the procedure, you should not rub your eyes. You should also avoid contact sports (football, basketball, etc.) and hot tubs and swimming pools for a couple of days. There are no visible traces of surgery on the eye. An eye doctor who is not looking for the procedure could even miss it with instruments.

Advanced femto LASIK with custom elliptical flap for astigmatism correction
Optimal astigmatism correction with LASIK requires advanced features because of particular geometrical and optical constraints. Using the Alcon/Wavelight refractive suite, bilateral correction of high myopic astigmatism can be achieved using beneficial features such as :
-custom elliptical flap creation
-optical axis centration
