ReLEx SMILE, LASIK or PRK surgeries

What does it mean and to whom are they addressed to?

If you do not like to wear glasses or you are tired of contact lenses, then laser eye surgery is the right option for you.

The principle of laser surgical procedures is to reshape or polish the cornea – the first lens of the eye through which light enters. This remodeling corrects the focus of light on the retina and eliminates the need to wear glasses or contact lenses. Basically, the laser ‘cuts’ the diopters’ equivalent to the glasses from the thickness of the lens of the eye, the cornea.

ReLEx SMILE (initials from Small Incision Lenticule Extraction) is currently at the forefront of laser correction of myopia and myopic astigmatism. It is the newest generation of corneal diopter reduction methods and is made with a single laser, the Femtosecond one.

It is considered a minimally invasive procedure, with high accuracy and the fastest execution. The SMILE procedure is performed in a single stage, without flap (Femto LASIK cap), so with the least possible intervention on the cornea. Using the latest generation Visumax laser, Carl Zeiss Meditec, a “refractive lens” is cut into the thickness of the cornea, having a specific shape, corresponding to the correction of myopia or myopic astigmatism of the patient. Subsequently, the laser makes an incision of about 2-4 mm through which the surgeon separates and removes the lenticule. Basically, it is a technique that uses a single “all-femto” laser, and the duration is about 25 seconds regardless of the diopter value.

FemtoLASIK is the second generation, the most widespread and most widely used laser surgical procedure to correct vision problems. It is a precise, fast and painless procedure. It is made with 2 different types of high-performance lasers – one cuts a corneal cap that is raised and the second grinds the cornea under this cap which is then put back. The advantages of this procedure are: postoperative comfort and fast healing.

PRK is the first generation of refractive surgery in which the laser directly grinds the cornea to the surface. It is used in people with low myopia, thin cornea or other special indications.

Over the last 40 years, tens of millions of laser diopter reduction procedures have been performed worldwide, with exceptional results, making these procedures among the safest in modern surgery.

What are the benefits of ReLEx SMILE, LASIK and PRK

The ReLEx SMILE procedure corrects:

  • myopia up to -10 diopters
  • myopic astigmatism up to -5 diopters
  • myopia and astigmatism up to -15 diopters cumulated

Depending on preoperative assessments, using FemtoLASIK procedure we can correct diopters as follows:

  • myopia up to -10 diopters
  • myopia and astigmatism up to -10 cumulative diopters
  • farsightedness up to +6 diopters
  • farsightedness and astigmatism up to +5 diopters cumulated.

The PRK technique can correct:

  • 6 diopters in myopia
  • 4 diopters in myopic astigmatism

What are the differences between ReLEx SMILE, LASIK and PRK?

ReLEx SMILE is the latest generation procedure, the least invasive of all. Thus the outer layer of the cornea keeps intact the collagen fibers and nerve threads that would otherwise be sectioned by the flap. It will result in a better resistance of the cornea in case of trauma, preservation of nervous sensitivity, a quality tear film (prevention of dry eyes) and a much faster recovery. 

FemtoLASIK is the most used procedure due to the larger correction range on which it can be operated, as well as the postoperative comfort and fast healing. The procedure is painless both during and after the operation.

PRK eye surgery is a procedure used especially in the case of low myopia or thin cornea that does not allow the cutting of the FemtoLASIK cap. The procedure is painless during the operation but the healing takes longer and patients may feel pain in the first days, for which treatment is prescribed.

What happens during surgery?

Regardless of the technique (prk eye surgery, lasik cataract surgery or ReLEx Smile), the procedure takes 5-7 minutes for each eye (of which the laser action is less than 1 minute) and is performed with local anesthesia, without hospitalization. Basically, you can expect the time spent in the clinic to be about 2 hours, which includes all the stages – from preparation, the actual procedure and learning how to take care of your eyes at home, in the healing stage.

The whole operation is painless and you will be installed very comfortably on a fully automatic bed. You will need to focus your vision on a bright spot, not talk and not move. You will be awake and the doctor will constantly explain to you what he is doing and what to expect.

What to expect after surgery?

After the surgery, the result is spectacular, obvious immediately after the procedure. The visual acuity will continue to improve day by day.

In a few hours after the SMILE procedure, the vision improves significantly. From the next day, you can return to your usual activities (working on the computer, watching TV, driving) and in a few days you can put on make-up, swim in the pool or do sports.

After FemtoLASIK cataract surgery, you can notice a significant improvement of vision in the first postoperative day with rapid progression in the following days. 

Recovery after PRK eye surgery is slower than in the case of FemtoLASIK in both visual acuity and healing.

In some cases or if the corrected diopters were of high value, it may take several weeks or months for complete healing. It is important to follow the doctor’s instructions, in terms of treatment and schedule of postoperative checks, as the healing process and the outcome of the operation can be greatly influenced by postoperative behavior.

What technology do you use?

At Clario we use the most advanced refractive surgery lasers in the world, produced by Carl Zeiss Meditech: the Zeiss Visumax femtolaser and the Zeiss Mel 80 excimer laser. We enjoy an excellent collaboration with Zeiss engineers who permanently ensure perfect working conditions for our equipment.

Frequently asked questions about laser surgery

Am I a suitable candidate for laser refractive surgery?

There are a few conditions you need to consider. Age, general health and eye health are the most important. It is mandatory that you have turned 18 when you come in for a consultation and sometimes, it is even necessary that your age is over 21 years.

There is no upper age limit for laser eye surgery. But you should know that after 40 years there is a need to use glasses for close activities (reading, writing) due to presbyopia.

If my eyes are healthy, am I a good candidate for laser eye surgery?

The absence of any evolutionary eye disease is an essential condition in eligibility for eye surgery. But it’s not always enough. There are other criteria that must be taken into account.

The thickness of the cornea (the lens at the front of the eye) is very important, as vision correction is done by reshaping the tissue of this lens. It turns out that a minimum corneal thickness is required, a limit beyond which the operation can become risky for the eyes.

The pupil diameter should not be too large. If the pupils are naturally large, there is a risk of unpleasant visual effects after the operation: halos, bright images at night, especially when driving.

High diopter values ​​may limit the possibility of complete reduction. The results of laser refractive surgery for large diopters can be unpredictable and can have a risk of visual complications. In these situations, other intraocular procedures for vision correction may be recommended.

Do my diopters need to be stable?

It is recommended that the diopters become stable at least 1 year before surgery, especially in the case of myopia, where the diopters generally increase gradually until you turn 18 years old. Young patients should wait until their diopters stop evolving. Otherwise, the result of the procedure will be affected by the subsequent evolution of the diopters.

What diseases could prevent me from being a good candidate for laser refractive surgery?

Evolutionary eye diseases such as keratoconus, diabetic retinopathy, glaucoma, macular degeneration, severe eye dryness, cataracts, and eye inflammation prevent you from performing laser refractive surgery. There are other surgical options in such situations.

Degenerative or autoimmune diseases such as diabetes mellitus, connective tissue disease, Sjogren’s syndrome, rheumatoid arthritis, HIV infection affect the postoperative healing and are contraindications for laser surgery.

Can I undergo laser refractive surgery if I am pregnant or breastfeeding?

These periods of time in a woman’s life lead to hormonal changes and have the effect of diopter instability. Dry eyes caused by hormonal changes contraindicate laser eye intervention, as well as the need to use drugs before and after surgery, which can harm the child. Therefore, it is recommended to wait a few months (at least 3 months) after you stop breastfeeding and then you can consider the evaluation for laser refractive surgery.

What results should I expect after laser refractive surgery? Is the operation safe?

The results after the operation are excellent and the patients enjoy a normal view without glasses. FemtoLASIK is a safe and effective procedure and 98.8% of patients are satisfied/very satisfied with the results of the operation.

Your expectations must be realistic. Vision acuity depends on the value of the diopters and other parameters measured before surgery. Almost all patients end up seeing without glasses after surgery, as much or better than they saw with glasses before surgery.

What complications can occur? Is the procedure safe?

You should be aware that there may be risks and possible side effects after laser refractive surgery.

Possible complications that may occur after surgery: infection, chronic eye dryness, visual halos and fog, subcorrection, overcorrection, flap-related complications, retinal detachment.
Less than 1% of patients have severe postoperative complications. The vast majority of them are treatable and are usually resolved in the first months after surgery.

Will I ever need glasses or contact lenses again?

We humans are very different and the eyes, like the whole body, change over time, but at a different pace for each of us. Sometime after the age of 40 you may need reading glasses because the onset of presbyopia begins, a normal, age-dependent phenomenon.
