Dr. Claudio’s studio is the only center throughout north Italy to use this technique. Now onwards, Corneal surgery will never be the same.
What is the RELEX SMILE technique ?
How much time is needed for the concern of the patient to turn into a smile?
The RELEX, is a completely new technique for correction of vision, through the use of femtosecond lasers. It is the result of a revolutionary principle, by the ZEISS researchers. It involves removal of a small biconvex lens sculpted intact by the femtosecond laser in corneal depth. The volume and shape of this lens depends on the correction of the visual defect. The lens is thicker at the center and its extraction flattens the cornea by decreasing the radius of curvature. It can be done using the femtosecond laser VISUMAX of Carl Zeiss Meditec.
This is an exclusives procedure asthe lasers of other brands are not aware of this technology. The VISUMAX is a new type of femtolaser, which projects a generation ahead of its competitors, making them outdated. We have been using this technology since 2011.
It allows us to perform a correction of myopia throughout the femtolaser without having to split the operation into two parts as is commonly done with FEMTOLASIK:
- The first groove of the corneal flap with the femtolaser,
- The second of myopia correction with the excimer laser.
The RELEX is divided into two types of intervention, the FLEX and SMILE.
In the FLEX the correction of myopia and astigmatism takes place, flattening the corneal curvature.
The SMILE is still a step ahead of the FLEX.

It offers many advantages:
1) Less INVASIVE (absence of corneal flap)
2) FASTER (using only one laser)
3) Extremely SAFE
4) Major FORESEEABILITY (especially in high myopia)
5) Increased STABILITY (especially in high myopia)
6) IMMEDIATE RECOVERY
7) Less PAIN
8) MINOR EYE DRYNESS
9) STRONGER Biomechanics
10) MOST CORNEAL SENSITIVITY
Who can be operated with SMILE technique?
The inclusion criteria are:
Myopia up to 10 diopters
Astigmatism up to 5 diopters
Thin corneas, inoperable with other techniques
Dry eyes, hardly operable with other techniques
Which is the best laser technology for professional athletes?
The SMILE is definitely the best technique for athletes, because the cornea remains virtually unscathed and you do not need a break .
What is refractive surgery?
The cornea is the front, transparent eye.
It is the first of the two lenses of the eye, as if it were the first of the objectives of a camera.
The refractive surgery reshapes the surface, modifying the radius of curvature, in order to increase or decrease the refractive power of the cornea.
In this way the defects of pre-existing views can be cancelled. This type of treatment involves the use of an excimer laser, which emits a beam of
coherent light in the ultraviolet spectrum to vaporize some tens of micron (thousandths of a millimeter) of corneal tissue. Everything happens with a precision and absolute repeatability, not obtainable with other methods.
There are other surgical techniques that relate to particular cases in which the laser is not indicated. You can then insert folding soft lenses within the eye, in order to also correct the defects of higher sight with great accuracy and as much satisfaction.
Only a careful examination done with the help ofthe required specialized tests, prescribed by an eye doctor can determine the personalized choice of the type of intervention.
The methods described below use excimer laser to change the curvature of the cornea.
They differ in their approach to the deep tissue (corneal stroma) where it uses the excimer.
PRK (Photo Refractive Keratectomy) involves the removal of the superficial corneal tissue (epithelium) with a blunt spatula to allow the use of the excimer laser on the underlying tissue (stroma).

The epithelium re-grows and closes the corneal abrasion in 3-4 days andfor the purpose of mitigating the pain, a protective contact lens is applied.
During this period we recommend rest at home and taking pain medication for a few days
LASIK (Las assisted er I n situ eratomileusis K) differs from PRK, because the approach to the deep plane of the cornea, where the excimer laser will have to exercise its action is guaranteed by a razor blade cutting, a round blade or corneal flap, which opens as the porthole of a washing machine or a ship.

The microkeratome creates a corneal flap. This is done with the use of a a scalpel blade mounted on a mechanical device with gears, which, with a go and come mechanism, mechanically cuts a superficial corneal layer to create thecorneal flap. Only after it has been raised, the excimer laser can act on the underlying stroma.
LASIK femtosecond is also called:
NO BLADE LASIK
BLADE FREE LASIK.
It is a LASIK WITHOUT SCALPEL.
It differs from LASIK because the washer or flapcorneale is separated gently from the floor below by the expansion of a series of gas microbubbles, created in the depth of the corneal tissue with a custom design for each eye, conceived and performed by a complex management program.

It is the newest refractive surgery, the safest and most effective technique.
The femtosecond laser is a new laser for eye surgery The name is related to the pulse duration of femtoseconds (1 femtosecond = 10 to - 15 seconds).
For a comparison, you may remember that one femtosecond is the time required for an electron to move from one atom to another.
Recalling the formula, Power = Energy / Time, it's easy to understand that, thanks to a pulse duration so short, a few femtosecond can be used on the cornea for very low levels of energy.
Thanks to this innovative method we are able to obtain a more precise cut and increase the level of safety of the surgery. The evolution over time has led today to Femtosecond Laser Generation IV.
This intrastromal laser got FDA (Food & Drug Administration, the federal oversight body of the United States) approval in December 1999.
WITHOUT SCALPEL, WITHOUT PAIN
The treatment is carried out under the guidance of an operating microscope combined with femtosecond laser, controlled by a computer.
This makes it possible to act exclusively on the corneal plane, leaving the corneal tissue intact.
Once the optimal level of depth is reached, the laser beam generates a series of micro gas bubbles, close to each other, which, by expanding, gently separate the tissues, without producing heat and are able to perform any geometry of cutting .
The bubbles created by the beam of femtolsaser, gently separate the tissue with no heat production.
Lying on your ophthalmologist chair you will be placed under a coaxial surgical microscope to the femtosecond laser, controlled by an accurate and personalized e-management program.
The treatment is performed within minutes.
The duration of the pulses of the femtolaser is a maximum of 22 seconds per eye.
After turning the table 180 degrees you undergo the action of the excimer laser, coaxial to a second operating microscope, which is managed by a specially developed and patented software.
The corneal flap created by femtosecond laser is raised to proceed to treatment with excimer laser with an average duration of less than one minute.
Why is it better to create a blade with a femtosecond laser cut with a microkeratome?
A microkeratome is a scalpel mounted on a mechanical device with gears that move forward and backward, cutting the cornea & creating a superficial corneal tissue lamella.
It is capable of working only on a horizontal plane, such as a planer, while the cornea is curved. Also you can meet all the drawbacks of a complex system of gears, as in high watchmaking.
The femtolaser used at Dr. PANIC is the only one that can perform cutting geometry significantly higher than the blades of the microblades/ The ZEISS has recently developed a new procedure for the correction of refractive defects with the exclusive use of Femtosecond Laser called RELEX . Itis divided into: FLEX and SMILE.
The technique used in the center of Dr. PANIC is the most recommended technology worldwide and is used by NASA for its astronauts and authorized by the US military and security bodies and provides guaranteed results.
It does not involve an actual cutting of the cornea, only generates a single layer of gas microbubbles.
The treatment can be stopped at any time and be resumed after a few minutes or after several days.
The surgeon can create a personalized treatment by sizing the diameter, depthand angle of the corneal lamella according to the shape and the size of the eye of the patient.
With this flexibility, even those who have thin corneas or large defects, unsuitable for treatment by other techniques, might be rectified with this treatment
• NO PAIN OR AS PART
• NO INCREASED INTRAOCULAR PRESSURE
• NO PAIN OR LACK OF VISION DURING TREATMENT
Treatment with the Femtosecond laser is not painful.
You can continue to see throughout the duration of treatment and the feeling will be similar to that of inserting a soft contact lens in the eye.
With the femtolaser technique you may experience discomfort and watery eyes for a few hours after surgery. Generally, the day after, daily activities can be resumed. If the treatment is carried out on Friday, youcan return to work three days later, i.e. on Monday.
With PRK, however, you must use protective contact lenses for five days and take pain medication as you can have pain for 24-48 hours, accompanied by eye irritation and watery eyes. It is advisable to return to work no earlier than 10-14 days.

How do you locate ophthalmologists and laser refractive surgery centers equipped with the best equipment?
It is the short-sighted, those with astigmatism, farsighted and presbyopia, determined to change their lives seeing better, who would like to resort to laser treatment, but fear any inconvenience, if they were to happen in the wrong hands.
In Italy at least 150,000 operations are performed each year.
In addition, the team and structure, you have to assess the curriculum as well, There are serious professionals and laser structures with first-class equipment, but there are also unscrupulous individuals who would operate all and in any case, in order to maximize gains, in facilities with older equipment.
How do you locate ophthalmologists more prepared and laser refractive surgery centers equipped with the best equipment?
It is the concern that captures the short-sighted, those with astigmatism, farsighted and presbyopia, determined to change their lives seeing better, would like to resort to laser treatment, but fear any inconvenience, if they were to happen in the wrong hands.
In Italy at least 150,000 operations are performed each year.
The specialist has to say, to patient protection, which not everyone can be operated and not always possible to eliminate the defect.
You have to assess well the curriculum, experience, keeping it updated, through participation in conferences on the subject and the number of operations performed. Should be considered, in addition, the team and structure.
There are serious professionals and laser structures with first-class equipment, but there are also in this industry, unscrupulous individuals who would operate all and in any case, in order to maximize gains, perhaps in facilities with older equipment.
You should go for the latest generation of laser centers as compared to those that have old equipment and are less reliable. In particular, we must inquire whether the excimer laser is equipped with an eye tracker. This particular mechanism allows the recognition of the iris of the patient and is able to move the laser synchronously to the micro movements of the eye.
Make sure that the refractive surgery center you choose owns a femtosecond laser, which allows a more precise and secure surgery with LASIK technique. The best Femtosecond lasers are those with an operating frequency of 500 kHz which allows better cutting. In essence, as the surgeon must be up to date on new techniques, so the center
must invest on the most modern technologies.
The femtolaser technique is a safer and innovative treatment that is slowly spreading and supplanting all other previous techniques, making them obsolete.
