Reduction of laser diopters. Fast high-tech procedures.

Glasses cannot replace the best visual tool in the world: YOUR EYES.


Laser operations to reduce dioptres have a history of over 40 years and currently millions of such interventions are performed annually all over the world.


Technology has advanced tremendously in recent years, propelling laser surgery among the top, safest surgical procedures. This is due to the speed of execution and strict action on the ocular surface.


At Clario we use ZEISS technology, the world leader in refractive surgery.

Correction of all refractive errors. Plus presbyopia

Myopia, hypermetropia and astigmatism can be corrected with a laser starting from 18-20 years old, provided that the diopters are stable for at least one year. A patient can be eligible for one procedure or several, only the doctor after investigations will tell you concretely what suits you best.


Presbyopia, i.e. the decrease in visual acuity almost after 40 years, benefits from an innovative technique that will get rid of near or progressive glasses.

Laser procedures in brief

  • PRESBYOND Laser Blended Vision Presbyond is the most advanced ZEISS laser procedure, the only one that corrects presbyopia - near vision difficulty appearing after 40 years but also other pre-existing refractive errors.
    See details PRESBYOND
  • ReLEx SMILEIt is the third generation of laser procedures for the correction of myopia and/or myopic astigmatism. Considered the least invasive and performed in one step with the ZEISS Visumax femtolaser.
    See ReLEx SMILE details
  • Femto LASIKFemto LASIK is the second generation of laser procedures and the most commonly used worldwide due to its versatility. Femto LASIK corrects myopia, hypermetropia and/or astigmatism and is performed with two types of lasers: femtosecond and excimer.
    See details Femto LASIK
  • PRKPRK is the first generation of refractive surgery in which the laser directly polishes the cornea, on the surface. It is a technique reserved for myopia with low values or people who have a thin cornea.
    See PRK details

How does the laser reduce diopters?

The laser precisely reshapes the cornea – the first natural lens of the eye – to reduce the diopters that until now were compensated by glasses, thus achieving the correct focus of light on the retina.


All procedures are very fast, the laser acting in seconds and the surgeon’s maneuvers are minimal. The anesthesia is local, with drops, the patient is always awake and does not feel any discomfort.


The goal is for the patient to have the best vision their eyes can achieve without glasses. The quality of vision is influenced by the health of all structures of the eye.

Pre-operative investigations

Laser reshaping requires thorough and very precise measurements of all structures of the eye.


Investigations include:

  • Pentacam corneal tomography
  • Specular microscopy
  • Corneal topography
  • Pachimetry
  • Tomography of the retina and optic nerve
  • Pupillometry
  • Computerized perimeter (if applicable)

Recovery after dioptre reduction

You will see immediately after getting up from the operating bed, but the vision will be “like through water”. For a few hours you may have stinging, watery sensations and you will be bothered by bright light.


In most cases, the recovery is very easy: immediately after the operation, the vision is improved, and from the next day the patient can resume most of his activities.


Healing takes place at everyone’s pace and depending on the procedure performed, it can last from a few days to a few weeks. Postoperative treatment in the first two weeks consists of antibiotic and anti-inflammatory drops.

Modern operating room

The Clario operating room is equipped with the latest surgical and sanitary safety and sterility technologies.


Dioptre reduction is done with a combination of ZEISS Visumax & MEL femtosecond and excimer lasers, the world leader in this field.


The surgical table comes from Brumaba, leader in comfort and reliability.

Frequently asked questions about laser dioptre reduction

Is it necessary for my diopters to be stable?

Young patients should wait until their dioptres stop evolving. It is necessary that the diopters are stable for at least 1 year before the operation, especially in the case of myopia, where the diopters generally increase gradually until the age of 18-20 years. Otherwise, the result of the procedure will be affected by the subsequent evolution of the diopters.

For over 40 years, in the case of presbyopia / Presbyond surgery, it is not necessary for the diopters to be stable before the surgery. Presbyopia itself involves a continuous and slow increase in diopters for nearly as the lens ages.

If my eyes are healthy, can I have laser surgery?

The absence of any progressive eye disease is an essential condition in eligibility for eye surgery. But it is not always enough. There are other criteria to consider.

The thickness of the cornea (the lens in the front part of the eye) is very important, as vision correction is done by remodeling the tissue of this lens. It follows that a minimum thickness of the cornea is required, beyond which the operation can become risky for the eye.

The diameter of the pupil 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 eye surgery for high diopters can be unpredictable and carry a risk of visual complications. In these situations, other intraocular procedures may be recommended to correct vision.

What diseases could prevent me from laser eye surgery?

Evolutionary eye diseases such as: keratoconus, diabetic retinopathy, glaucoma, macular degeneration, severe eye dryness, cataracts, eye inflammations prevent you from laser dioptre reduction surgery. There are other interventions in such situations.

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

What results should I expect after laser surgery?

The results after the operation are excellent and patients enjoy good vision without glasses. Recovery is in most cases very fast and the patient resumes his activities the next day.

Your expectations must be realistic. The visual acuity depends on the optical system of the eye that is corrected by these interventions but also on the quality of the retina and the optic nerve and other eye structures. The goal of the surgery is for the patient to see without glasses after the surgery, as well as they could see with (properly prescribed) glasses before the surgery.

What complications can occur? Are the surgeries safe?

Laser diopter reduction interventions are considered to be among the safest in surgery in general. All over the world, millions of such procedures are performed annually and their history is already over 40 years old. Meanwhile, technology has advanced enormously, making them safer and faster.

However, you must be aware that there may be risks and possible side effects associated with any medical procedure. Although extremely rare, possible complications that may occur after surgery are: chronic eye dryness, visual halos and fog, undercorrection, overcorrection, flap-related complications, retinal detachment, infection.

The vast majority of complications are treatable and usually resolve within the first few months after surgery.

How long does the effect last? Do the diopters come back after a while?

Laser dioptre reduction is permanent and very stable over time. There is no risk of the previous dioptres returning.

It should be taken into account that the evolution of the eye’s structures over time can bring about a slight change in the diopters, independent of the intervention. It is the case of the lens that loses its elasticity and begins to add diopters for almost after 40-45 years and after 60 to slowly develop cataracts.

In the case of large dioptre reductions, especially on plus, there is a risk of regression by remodeling the eye during healing.

I'm afraid of surgery, what alternatives do I have?

The fear of operations is understandable, but in the case of laser procedures, the interventions are extremely fast and do not involve any discomfort. Although they are done in an operating room with all the related protocols, they can hardly be called “surgical operations” in the sense known to everyone. Patients say almost without exception that they did not realize when it happened and regret not having done the intervention sooner.

In order to see well after the appearance of presbyopia, glasses are worn for near or progressive glasses if there are other previous refractive errors.
