Femto-Lasik

Introduction

Femto-Lasik is the most recent ocular laser technology intended for people who can see without glasses or contacts. Whether you suffer from short-sightedness (myopia), long-sightedness (hypermetropia/hyperopia), astigmatism, or age-related long-sightedness (presbyopia): all these sightedness conditions can be treated with the Excimer laser and without problem

With Femto-Lasik laser eye surgery, we make the flap in the cornea with the newest type of laser: the Femto-Second. The Lasik procedure is now even safer: there are much fewer risks of complications during the procedure and the flaps are much thinner. This offers a better chance of greater stability to the cornea over time. Never before have safety, accuracy and patient comfort in laser eye surgery been so good, as proven by many thousands of FEMTOLASIK treatments

What is a Femto-Lasik procedure?

FEMTOLASIK 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 blade-free and enables the surgeon to tailor the procedure according to the very unique characteristics of every patient. A truly personalized treatment for everybody!

Why FEMTOLASIK

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 eye is reduced to a minimum. FEMTOLASIK is comfortable and painless: The patient 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 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.

Advantages to the Femto-Lasik procedure

  1.  Greater safety
  • Significantly reduced risk of problems with the corneal flap 
  • Reduced risk of inflammation or infection
  • Larger treatment surface with better stability
  • Less need for repeat treatment
  1. Thinner flaps

With the Femto-Lasik, the corneal flap is so thin and so cleanly incised that no side effects generally result. With thin flaps, more tissue-bed is left over. This offers a greater guarantee of the stability of the cornea over the long term and makes it possible to correct a wider range of visual impairment.

3. Better predictability to flap thickness

The surgeon knows in advance and with certainty the form, the thickness, the size, and the condition of the flap. This is relevant to the treatment strategy for higher levels of vision impairment. Where the flap is incised by scalpel, it is only afterward that the surgeon can judge what the flap looks like.

4. Other advantages

  • The dimensions of the eyeball are not important for Femto-Lasik eye surgery.
  • Your recovery is faster and you can begin to see properly again sooner.
  • The outcomes for vision are excellent.
  • With the Femto-Lasik laser, less pressure is put on the eye during surgery, and this means more comfort for the patient

 

When is LASIK  surgery recommended?

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.

 

What Happens During LASIK Eye Surgery?

The Femto-Lasik laser operates on the principle of photo-disruption: with infrared laser energy, the surgeon creates a precise pattern of small, overlapping spaces just under the surface of the cornea. The laser works at extremely fast speeds: pulses of 1 quadrillionth of a second or 1 femtosecond.

These precision-guided pulses of laser light break down the corneal tissue at the molecular level each femtosecond, without generating heat or interfering with the surrounding tissue. When the laser moves over the eye, it incises a completed flap in the cornea. Once this flap has been created, the surgeon can tilt it up with a specially designed surgical tool. Thereafter the Excimer laser is used to re-sculpt the cornea and correct eye problems. Finally, the surgeon puts the flap back in its place

The operation

Step1: 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 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 anesthetic 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 to 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.

Results of FEMTOLASIK

What are the risks?

Just as any other surgical procedure, FEMTOLASIK may have side effects.
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). With Femto Lasik therapy for hypermetropia and presbyopia, partial regression in the result could occur after a number of years. Up to now, surgeons would perform a further corrective procedure
