Diopter reduction with the SMILE PRO technique

SMILE PRO is the second generation of SMILE surgeries. Following the success of RelEx SMILE, Zeiss has developed the next level of this technology.

What does the SMILE PRO surgery involve?

SMILE® is a minimally invasive incision that creates only a small incision (80% smaller than LASIK).

The SMILE PRO technique is performed without a flap (corneal flap) and without removal of the corneal epithelium. It preserves corneal tissue, there is no pain during the surgery and recovery period, it takes a little time and visual acuity stabilizes very quickly after the surgery.

Smile PRO takes only 7 seconds, and can also operate + diopters (coming soon)!

Step 1: Creating the lenticule

A lenticule and a small incision are created inside the intact cornea.

Step 2: Lenticule removal

The lenticule is removed through a small incision with minimal disruption of the cornea.

Step 3: Correcting the refractive error

Removing the lenticule changes the shape of the cornea, correcting the refractive error.

What are the benefits of SMILE® PRO?

SMILE® Pro is a one-step laser procedure

SMILE® Pro is performed in just 7 seconds

SMILE® Pro leaves the upper layers of the cornea less affected, which means a much lower risk of dry eye or infection after surgery.

SMILE® Pro has a faster recovery, with patients able to see well immediately after surgery

SMILE® Pro is silent and odorless

SMILE® Pro is suitable for people who practice contact sports, surfing or for those employed in the military or as flight personnel.

Who is SMILE® PRO surgery recommended for?

Patients over 20 years of age who have had stable refraction (diopter) for more than 12 months.

Myopic (nearsighted) patients or patients with astigmatism

People who have good vision with glasses or contact lenses

When is SMILE® PRO not recommended?

Pregnant or breastfeeding patients (first 6 months at least)

Patients over 40 years of age.

Patients with thin corneas or suffering from keratoconus.

What are the risks of SMILE® PRO laser surgery?

Although the risks are minimal and very rare, as with any intervention, they can occur.

Although less than in case of other surgeries, there may still be a risk of infection and scarring. It is important to complete post-operative treatment with eye drops and check-ups to avoid this.

During the procedure, there may be a case of what is known as aspiration loss. If this happens, another type of vision correction may be required. In the rare case that this happens, everything will be explained to you.

SMILE® is the latest laser eye surgery technique. As a result, there are no long-term studies. However, the level of predictability is high. With over 2 million successful surgeries completed worldwide, the risks of complications are rare and are considered less than 1 in 5000.


What to expect during SMILE® PRO surgery

Before surgery

Our team will explain you step by step what you need to do in preparation for the surgery, right from the last examination. It is necessary to stop wearing contact lenses at least a few days before the surgery, but this time varies from patient to patient, depending on each case. Your doctor will tell you at your initial examination how long you need to go without contact lenses. You will also be prescribed a treatment with eye drops in the days before the surgery.

On the day of the surgery, Dr. Holhoș will see you once more before the surgery.

You will be prepared for surgery by our nurses, and led into the operating room.

During the procedure

The full SMILE® Pro procedure (setup and surgery) takes approximately 5-10 minutes per eye. It will be a pain-free experience as topical anesthetic (eye drops) will be administered to numb the front of the eye. You will also have an instrument inserted under your eyelids to prevent you from closing your eye or blinking during the procedure.

Your doctor will talk you through the procedure with instructions on where to look. It is common to feel a bit of pulling as the doctor removes the lenticule, however, it does not hurt. Once treatment is complete, we will apply both an antibiotic and eye drops.

It is normal for vision to appear blurred immediately after surgery. It is very important not to rub the eye after the surgery.

Postoperative recovery

A check-up will be carried out the following day, followed by another check-up a week later. It is mandatory to follow the prescribed treatment with eye drops after the surgery.

A 3-month and then 6-month check-up is necessary to test your vision and make sure everything has healed successfully.

SMILE PRO is the second generation of SMILE surgeries. Following the success of RelEx SMILE, Zeiss has developed the next level of this technology.

RelEx SMILE laser surgery is the most up-to-date technique for reducing diopters, which can be performed with the Carl Zeiss Meditec VisuMax femtolaser laser.

The FemtoLASIK surgery is part of the suite of refractive surgeries available in the Dr. Holhoș network, and is part of the 2nd generation of laser surgeries.

Excimer Laser Diopter Reduction surgery is for those who want to get rid of glasses and have been diagnosed with myopia, astigmatism, myopia and myopic astigmatism, hypermetropia.

Presbyopia is an age-related disorder that makes it more difficult to see nearby objects.

High diopters (myopia, hypermetropia, astigmatism or presbyopia) can be corrected with a lens implant. The procedure is similar to cataract surgery, except that in this case the lens is replaced before the cataract appears.

Lens implant surgery (cataract surgery) is necessary for people with cataract and is the only method of treatment. Find out what the surgery involves and what the consequences are.

The eye is a very complex organ, the component parts working as a whole so that we can see. The center of the eyeball contains vitreous fluid, a clear gel that maintains the spherical shape of the eyeball.

The vitreous body is located in the center of the eyeball, between the lens and the retina, and appears as a “gel”. A healthy vitreous is completely transparent allowing light to reach the retina without any problems, resulting in a clear vision.

Retinal membranes are diseases of the interface area between the back of the vitreous and the central area of the retina, the macula; they are characterized by the appearance of a translucent “sheet” in this area, which pulls and folds the macula, thus affecting the retinal cells and causing specific symptoms.

Glaucoma is a chronic, bilateral eye disorder characterized by progressive destruction of the fibers of the optic nerve, the nerve responsible for transmitting information from the eye to the brain. Learn more about glaucoma surgery.

Pterygium is a triangular extension of the degenerated bulbar conjunctiva (the transparent sheet above the eyeball) over the edge of the cornea.

Crosslinking surgery is the procedure used for patients with Keratoconus, a disorder in which the cornea is deformed.
