During surgery we use the new generation Allegretto Wave laser from WaveLight, which allows us to achieve the best results in laser vision correction.

The Allegretto Wave laser is a top-of-the-class excimer laser used to perform:   Standard correction of refractive errors (myopia, myopic astigmatism, hyperopia, hyperopic astigmatism) Surgery based on an individual topographic map of the patient’s cornea Correction of aberrations of the eye’s optic system Phototherapy

The laser is fitted with a precise, reliable and rapid active eye tracking system, which is synchronised with the triggering of a laser beam at the frequency of 200 Hz. Such speed minimises drying of the cornea during surgery on the one hand, and reduces the effects of external factors on the other. The small flying spot of the laser, measuring 0.68 mm in diameter and possessing a gaussian profile, guarantees high precision in the modelling of the surface and margin of ablation. Ablation is performed in accordance with the aspheric profile adjusted to the natural curvature of the cornea. All the values obtained during qualification assessments are entered into the laser’s software.

The most modern and safest methods of vision correction would not have been possible without yet another highly specialist piece of equipment. LASIK, SBK LASIK and EPI-LASIK require a microkeratome, which is used to prepare the field of operation for the laser. In order to be able to change the shape of the cornea the laser must reach the deepest layers of the cornea. And this is achieved thanks to the microkeratome, which is made up of a console and several heads specific for the type of surgery (One Use-Plus 130, One Use-Plus SBK,
Epi-K).

While the laser precision is the most important aspect for the accuracy of correction, the microkeratome is responsible for the majority of benefits associated with the course of surgery as well as the duration and quality of recovery after surgery.

The safety of surgery is largely dependent on the highest quality of the microkeratome. Documented safety is an advantage of the MORIA system, as indicated by clinical reports and authorisation to use on the US market by the FDA, authorisation to use in the EU (by the CE certificate) and authorisation to use in France, where an additional medical certificate is required that documents benefits compared to the previous methods.

The main advantages of the EVOLUTION 3E console include: • The low-pressure option: enables eyeball stabilisation during excimer laser ablation and gentle manipulation of the corneal flap while the knife is returning during microkeratome incisions. • The slow increase and decrease of low pressure reduces patient discomfort after the low-pressure option has been switched on. • Two head movement speeds allow the formation of the corneal flap individually, according to the patient needs, and easy fit to various shapes of the cornea.

The new, fully automated system with a disposable head, allows to perform new procedures in refractive surgery: • The high precision of performance guarantees constant parameters and reliable operation. • The high frequency of oscillations allows to obtain a corneal flap with very smooth edges. • The head comes pre-calibrated along with the knife, which offers a higher reproducibility of incision parameters. • The transparent head and ring enable constant observation of the corneal flap and the low pressure during incisions. • The double-port ring enables uniform adhesion to the cornea.

The following methods of laser vision correction are used at our Laser Eye Surgery Centre:

• LASIK (laser in situ keratomileusis): The most common method ensuring rapid regeneration and effects. The patient may resume their everyday activities as early as the day after surgery.
• LASEK (laser epithelial keratomileusis): A method used only in patiens whose corneas are too thin and when LASIK is contraindicated for some other reason. This method requires wearing contact lenses for 7 days after surgery.
• SBK LASIK (sub-Bowman keratomileusis): This is a more gentle variety of the LASIK method, in which a thinner flap is created. In the traditional LASIK method the flap is 130-180 µm thick (depending on the microkeratome used). In SBK, the use of a special microkeratome head, MORIA One Use-Plus SBK, allows to create a flap that is 70-100 µm thick.
• Epi-LASIK (epithelial laser in situ keratomileusis): Epi-LASIK is a modification of LASEK and LASIK. It is most commonly used in patients with thin corneas or at a high risk of injury (policemen, firemen, sportsmen, soldiers). In Epi-LASIK the surgical field for the operation of laser is prepared with the use of an epikeratome.

All the benefits and contraindications of each of the selected method will be discussed with the patient candidate before surgery.
