Femto-Lasik

Femto-Lasik is the most recent ocular laser technology intended for people who can’t see without glasses or contacts.Whether you suffer from short-sightedness (myopia), long-sightedness (hypermetropia/hyperopia) and astigmatism: all these sightedness conditions can be treated with the Excimer laser and without problem.

What is a Femto-Lasik procedure?

Femto-Lasik, is the newest type of ocular laser used to treat your sight problems.
Earlier–with the older laser-techniques–laser eye surgery started first on the surface of the cornea, and thereafter went deeper via a flap made in the cornea. In this older technique, the flap would be made by hand, with a scalpel.
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.

How does a Femto-Lasik laser work?

1.  with infra red laser energy the surgeon creates a precise pattern of small, overlapping spaces just under the surface of the cornea.
2. 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 surrounding tissue.
3. 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.
4. 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.

Advantages to the Femto-Lasik procedure

• 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
• 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 vision impairment.
• 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 afterwards that the surgeon can judge what the flap looks like.
• 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

What are the steps in a Femto-Lasik procedure?

Before surgery

1. Before the procedure we do the pre-operative measurements once more.
2. Your eyes are given local anaesthetic. You do not therefore have to undergo any general anaesthetic

During surgery

1. Nursing staff will help you to the operation bed in the laser treatment room.
2. Your eyes are thoroughly disinfected and covered with a sterile bandage.
3. Your eyelashes are held out of the way and your eyes are given a further dose of local anaesthetic.
4. A device holding the eyelids is set in place to stop blinking and closing of the eye. Making the corneal flap takes 26 seconds and uses a device which is placed on the eye. So you don’t need to worry: you cannot interfere in any way with the positioning of this instrument.
5. After opening the flap, the surgeon uses the Excimer laser to treat your particular eye condition. This involves you looking at a targeting light for 1 second, and thereafter the laser will automatically follow the movement of your eye. Finally, the flap is folded back, rinsed well, and fixed into place.

After Surgery

1. You are brought to the recovery and relaxation zone where you rest for about 30 minutes.
2. You should not drive the day of the procedure, so it’s best to come accompanied by family or friend!
3. Taking public transport is also not recommended.
4. The post-operative medication is eye drops and protective eye glasses which you must wear for 24 hours.
5. Follow-up examinations after the operation are scheduled for after the first day, after one week, and after one month.
