SMILE ® Pro: The gentlest form of laser eye surgery

LEC as member of EuroEyes was one of the first clinics to bring in the next-generation Carl Zeiss Visumax-800 laser. This new laser machine represents a significant step forward from the previous model and is the only way to provide cutting-edge SMILE Pro treatment.

While the procedure has always been relatively quick and non-invasive, the new technology will make it even faster, more accurate and less stressful for our patients. The Visumax-800 uses digital mapping technology to orient the laser to the eye for precision targeting during treatment ensuring it is correctly oriented for optimal treatment.

SMILE Pro is suitable for patients who are short-sighted and/or have astigmatism.

The VISUMAX ® 800 from ZEISS represents the latest generation of ZEISS femtosecond lasers and offers a shorter laser time compared to its predecessors, while tissue separation with SMILE ® Pro from ZEISS is easier than before.

What is SMILE® Pro?

SMILE (Small Incision Lenticule Extraction) is a minimally invasive procedure where a laser creates a lenticule (or disc shape) inside the cornea, which is removed through a tiny incision. This reshapes the cornea to optimise focus and sharpen vision.

The cornea is made up of five layers, but SMILE ® Pro surgery focuses on the central layer, known as the stroma. During surgery, a computer-guided laser creates a precise lens-shaped disc (known as a lenticule) in the stroma. The shape of the lenticule is customised to correct the specific shape of your cornea. The laser then makes a tiny keyhole incision, and the lenticule is removed. When the process is complete, the cornea is shaped to optimise focus and sharpen vision long term.

The laser portion of the procedure is quick it’s all over in under 10 seconds. The technology is also designed to ensure it’s an extremely comfortable procedure. Although everyone is different, recovery is quick – most people will be feeling great the very next day.
Comfort and ease
  • Short treatment time of only 32 seconds per eye.
  • Also suitable for patients with dry eyes.
  • Keyhole technology (incision of 2 mm) and thus rapid healing.
  • For myopia up to minus 10 diopters.
  • For astigmatism.
  • Suitable for patients with thin cornea, corneal stability is maintained.
  • No corneal flap.
  • Better corneal stability.
Tiny incision instead of flap: The SMILE Pro procedure is gentler on the cornea compared to LASIK.
Advantages of innovative technology that you benefit from immediately during your laser eye treatment:
LASIK 20 mm flap
SMILE Pro 2 mm minimally invasive
Until now, refractive correction has usually involved the surgeon first cutting a flap, which was then folded back to remove corneal tissue point by point. SMILE Pro now enables laser vision correction without a corneal flap and thus minimally invasive.
How does it work?
1. Creation of the lenticle and the incision
2. Removal of the lenticle
3. Rehabilitation
The first step with the VisuMax is to create a refractive lenticule and a small incision of no more than two to three millimeters in the intact cornea, which can be done almost independently of the surrounding conditions and corneal condition.
In the second step, the lenticle is removed through the created incision. Since no flap is cut, this is only a minimal intervention in the biomechanics of the cornea.
Removal of the lenticle changes the cornea to achieve the desired refractive change.
1. Non-binding, personal consultation
During a non-binding, personal consultation, your doctor will first clarify with you whether your eyes are basically suitable for SMILE Pro treatment. For this purpose, all relevant eye parameters will be measured.

2. Comprehensive preliminary examination
Before the operation, a comprehensive medical examination will follow. Before this examination, you should in any case refrain from wearing contact lenses, as they also change the shape of the cornea in the long term. You should not wear soft contact lenses for at least one week before the examination. For hard contact lenses, the interval should be at least two weeks. Lenses should then also not be worn in the same time window before the operation.

On the day before the treatment as well as on the day of the treatment itself, you should refrain from using cosmetic products such as face creams, lotions, and also make-up and perfume. They can increase the risk of infection or contamination of the surgical field. You should clean your eye area particularly thoroughly on the morning of the treatment day.

3. The SMILE treatment
On the day of the operation, you should wear comfortable clothes if possible. You can eat and drink normally, but should not smoke. For reasons of hygiene, you should wash your face thoroughly once again and completely remove any make-up residue.

Then the actual procedure takes place, which is performed on an outpatient basis and takes only about 20 minutes for both eyes. First, the surgeon will greet you and once again match your personal data before your corneal surface is anesthetized with drops. To prevent blinking during the surgery, you will be fitted with what is called an eyelid opener. The other eye will be covered during the procedure.

Next comes the preparation of the lenticule in the cornea using the VisuMax femtosecond laser. A contact lens adapted to the shape of the cornea is used to fix the eye. You will see a bright spot during these steps, but hardly feel anything. Once the surgeon has prepared the lenticule, he or she uses the laser to cut a small opening of no more than four millimetres, through which he or she releases the lenticule and carefully pulls it out. The small incision closes by itself after the correction, so it does not need to be sutured. No separate postoperative precautions are required. You will probably be amazed – as well as most other patients – at how quickly the procedure is over and that you hardly felt a thing. An eye bandage is not necessary, but sunglasses are recommended. No driving is allowed immediately after the treatment.

4. After the SMILE treatment
After the procedure, you should not rub your eyes. You will also receive antibiotic eye drops, which must be instilled into the eye five times a day for a week, as well as artificial tears – as needed. Normally, you can return to work after two to three days. You should also wait about three days before engaging in sporting activities. Swimming and sauna visits, on the other hand, should be avoided for about two weeks to reduce the risk of infection.

Medical checks take place after one day, one week and one month. Driving is allowed again only after medical permission, which can usually be given at the weekly check-up.
The femtosecond laser - technical facts
A femto-laser is an infrared light laser that treats tissue such as the cornea not only very precisely, but also with much less heat than other lasers. This proves to be a decisive advantage, especially in eye surgery. The femtosecond laser works on the basis of ultra-short light pulses. These last only fractions of a billionth of a second; their spot size is only 1/100 mm.

The VisuMax femtosecond laser
A specially developed laser system, the VisuMax femtosecond laser from Carl Zeiss, is used for SMILE treatment. This laser has already proven itself in Femto-LASIK procedures with its sophisticated technology, precision and reliability. Through further development, it is now possible for the first time to prepare a lenticule within the intact cornea with millimeter precision, so that larger incisions and a flap can be dispensed with. In this way, the surrounding corneal tissue is spared as much as possible and the visual defect can be corrected in a targeted manner.

In addition to its high precision, a particular advantage of femtosecond technology is that it is highly reproducible and accurately predictable even when high corrections are involved.

In order to avoid unnecessary compression of the cornea, a contact lens is used that is adapted to the individual corneal anatomy and allows a precisely fitting treatment. This also avoids short-term visual loss, which can be caused by excessive intraocular pressure.

In addition to state-of-the-art laser technology, a functionally sophisticated and ergonomically shaped patient couch has also been developed for ReLEx treatments, allowing for maximum comfort and the most relaxed position possible during the procedure. During the operation, the patient’s position is continuously monitored and can be automatically readjusted if necessary.
