IFS ADVANCED FEMTOSECOND LASER – THE LATEST IFS LASER
The latest iFS Advanced Femptosecond laser of the fifth generation of Abbot Medical Optics is currently the best laser for refractive surgery. The iFS Advanced Femptosecond laser provides surgeons with more control and more work options with maximum customization for each patient. With more than 4 million operations, the IntraLase patented technology used by this laser is the best choice for laser vision correction.
iFS laser allows:
Increased flap adjustment Increased biomechanical stability of the flap Faster recovery of visible sharpness Exceptional security With this new iFS laser, during reflex correction iLASIK, the formation of the flap (lid, lobe) at the top of the cornea is completely contactless, using laser beams that cut the cornea at a certain depth and thus provide a minimum invasive and maximum precise procedure. In comparison to previous generations,
iFS laser brings a few more novelties:
making an elliptical flap that allows a more symmetric redistribution of the force thereby creating a smoother surface of the cut making an adjustable flange edge (up to 150 ° angle), which allows increased biomechanical stability of the flap lower calculated energy at each laser pulse, and thus less damage to the surrounding tissue removal of dioptre laser removal of dioptre With the use of the iLASIK procedure,
The latest AMO iFS Advance Femptosecond iFS laser also provides advanced corneal treatment options. Thus, it is possible to perform keratoplasty, the installation of intra-rings, and the cut through the cornea during the cataract surgery, because the IntraLase technology provides extremely precise, and uniform cuts on the cornea in an almost infinite range of shapes.
WAVELIGHT ALLEGRETTO EYE-Q LASER 400HZ EXCIMER LASER
WaveLight Allegretto Eye-Q Laser is the latest generation of excimer lasers. By creating an individual profile of laser corneal ablation, computerized data are obtained from topographic corneal measurements and eye aberometry which allows perfectly precise and customized removal of dioptre in each individual patient.
Allegretto Wavelight uses invisible ultraviolet (UV) rays of 0.25 microns in size to remove extremely small parts of the corneal tissue to eliminate short-sightedness, farsightedness or astigmatism. The laser beam (1) in the diopter is removed for about 2 seconds. Less time under the laser means less stress and discomfort for you.
Revolutionary technology has gone several steps further to incorporate both laser software and built-in eye tracker with the ability to monitor eye movement at a rate of 400 movements per second. This technology allows the laser pulse to emit only a fully centered cornea, which ensures an extremely high degree of safety.
Perfect Pulse technology ensures control and adaptation of each individual laser beam to three different positions in the laser itself. If the air does not correspond to the given parameters or is not in the correct position around the patient, the device will not be missed.
Using the advanced Wavefront Optimized technology, exceptional reliability and high efficiency of the laser removal procedure of the diopter is ensured. Introducing this advanced technology improves the quality of night vision and disappears postoperative phenomena in the sense of lightening in the night.
AL-SCAN OPTICAL BIOMETER NIDEK
AL -scan biometer is used to calculate the axial length of the eye and the intraocular lens. It is an optical biometer that, for 10 sec, makes a complete biometric measurement of AL, ACD, CCT, K, PS and WTW. What gives an exceptional advantage to this device is that it includes 3D auto tracking and auto start, which enable fast and easy measurement. Also, additional probes for biometer and pachymeter are possible in dense cataracts. Keratometry and axial length measure this device in 360 points, which in turn gives greater accuracy. Of the other “virtues” of this April, we will list 8 formula for calculating IOL and optimising results, and Scheimpflug the front and the cornea.
ALCON ACCURUS 800 CS
The Accurus 800CS console is a modern technological achievement in Alcon’s rear segment operations, so from now on, in our clinic, our surgeon performs rear-end surgery, which is also the most complex surgical procedure for accessing the depth of the eye. Accurus combines several functions that are necessary for operations. With this device, surgery is performed at the depth of the eye (vitrectomy). It is very important to have an intraocular pressure and an irrigation pressure under control, since such surgical procedures involve an eye. Accurus is digitally controlled, at the request of the operator, they can be adapted to the conditions of the operation. During vitrectomy, lighting within the eye is very important for better visibility and transparency. The main function, by which the procedure is called, is vitrectomy. This procedure removes glassware from the eye, instrument called – vitrektom. Vitrect with a small hole cut and vacuum parts of the glass. With Accurus there are 3 types of possibilities for using vitrectoms (20G, 23G and 25G – dimension mark). The most commonly used 23 G vitrektom with which the procedure ends and without seams, which means not only greater comfort for patients, but also shorter service life.
Accurus xenon illuminator with cold light keeps retinal structures from thermal damage. Illumination is needed so that the operator can see the inside of the eye during the procedure. Accurussize Alcon uses a diathermy program, which, like other functions, is operated by a foot pedal. Accurus has many options to fine-tune the operating parameters, the frequency with which the vitrex performs while removing the stack is regulated up to 2500 cpm (cuts per minute – rpm). Work has shown that higher speeds are more convenient for work near the retina, because it reduces the possibility of traction, and there are fewer complications during the procedure, and fewer speeds are selected when removing the glass from the central parts of the eye. This reduces the incidence of intraoperative complications.
DCT PASCAL – MOST ACCURATE EYE PRESSURE MEASURER
Pascal tonometry finally available in Croatia!
Full name of this method is DCT-Pascal (digital countur tonometry-Pascal).
Unlike methods so far for measuring eye pressure (particularly compared to applanation method – most commonly used) Pascal provides ideal, realistic values.
Namely, using piezoelectric crystal on top of the measuring instrument, resulting values aren’t depending on biomechanical properties of cornea and values are equal as if eye pressure is measured directly, with manometer placed in ocular front cabin.
Pressure is measured 100 times in second and its dependence on difference of systolic and diastolic pressure.
Mere sensor stays attached on cornea for about 8 – 10 seconds and intraocular pressure is read afterwards.
Such values can be take into consideration with certainty and use them together with other antiglaucoma exams in precise diagnostics and glaucoma tracking.
FLUORESCEIN ANGIOGRAPHY (FAG)
Fluorescein angiography (FAG) is diagnostic test used for testing eye blood vessels (retina, choroid, iris) and also retina pigment epithelium (RPE).
ZEISS FUNDUS CAMERA FOR DIGIRAL ANGIOGRAPHY
In polyclinic, we use Zeiss Visucam fundus camera for photo documentation of posterior segment of the eye and fluorescein angiography.
VISUCAM fundus camera provides high quality records of posterior segment of the eye and representation of choroidal blood vessels and retina.
INFINITI ALCON
Infiniti Alcon is one of the finest appliances for the ultraspectral barbell operation on the market. It is distinguished by precise and proven work and stability of all the eye structures during the surgery. Namely, some other, simpler and older devices can not reflect the “quiet” surrounding parts of the eye that we do not want to “harass” while removing the blurred lens. This is very important, since these parts of microscopic diameters and any unnecessary trauma is not welcome because it can result in complications. That’s why it is very important to perform operations with a safe appliance.
KERATO-REFRACTOMETER SHIN NIPPON
Harmonious combination of precision and ergonomics in the modern kerato-refractometer of Japanese company Shin-Nippon. The device provides very precise visual acuity readings (up to +/- 30 diopters and +/- 10 cylinders) as well as keratometric measurements, all of which are completely uncontact and in less than a minute.
Corneal topography (ANTARES)
CORNEAL TOPOGRAPHY- COMPUTERIZED SCAN OF ANTERIOR SEGMENT OF EYE
Corneal topography is diagnostic test that is used to make „map“ or „relief“ of corneal surface. That way is possible to precisely determine radiuses of curvatures of corneal surface and also level of corneal distortion. By using corneal topography it’s possible to detect certain irregularities and eye diseases such as astigmatism and keratoconus.
In polyclinic, we use corneal topographer ANTARES (The most technologically efficient device)

PENTACAM – WAVELIGHT OCULYZER
Pentacam Comprehensive Eye Scanner is medical device, i.e. camera that most precisely analyzes anterior segment of eye and by that allows completely individualized approach to laser diopter removal. Couple of years ago precision in laser diopter removal was determined by amount of diopter and cylinders, but discovery of Pentacam changes that.
Rotating of Scheimpflug camera in all meridians allows precise three-dimensional representation of anterior segment of eye and by that also individualized approach in refractive surgical procedures.
It’s used for following measurements:
- corneal topography (elevation and curvature maps),
- corneal pachymetry in its complete surface area,
- tomographic analysis,
- 3D analysis of ocular front cabin,

OPTO-SLT laser
installed in a biomicroscope system with a projection lamp and is used for non-invasive surgical treatment of eye disease:
Selective laser trabeculoplasty – the most modern approach to treatment of glaucoma dr for SLTotal angle
Peripheral laser iridotomy – the most modern approach in the treatment of glaucoma of closed angle
Laser capsulotomy – Treatment of blunting of the back lens capsule (secondary cataract) after cataract surgery
Selective Laser Trabeculoplasty (SLT) is the latest approach currently in the world for non-invasive (without surgical eye opening) treatment of open-angle glaucoma and most cases can be considered a final treatment. This treatment allows the patient to resolve the lifelong drip of antiglaucoma drops forever.
The device uses a laser that acts selectively on specific cells in the trabeculum field of the eye angle containing pigment melanin. This achieves a better effect and reduces thermal damage to trabeculum caused by other non-selective lasers such as ALT lasers. In clinical trials, currently shows best results in non-invasive treatment of open-angle glaucoma. It uses less laser power and thus does not damage the structure of the trabeculum (visible by an electron microscope). This procedure can be repeated without any harmful effects on the eye.
LPI Laser Peripheral Iridotomy (LPI) is a method for selectively making a microscopic opening in the varicella near its base. It is used for non-invasive (without surgical opening of the eye) treatment of closed glaucoma. The procedure can be repeated several times.
SOCT COPERNICUS
POSTERIOR SEGMENT OF EYE SCAN- SOCT
By using OCT it’s possible to detect several retinal and optic nerve diseases at earliest stage. We especially emphasize early glaucoma diagnostics, where measuring thickness of nerve fibers around retinal nerve fiber layer (RNFL) and analyzing the head of optic nerve (PNO) can discover earliest stage of glaucoma disease that is impossible to detect with other methods.
Except for early detection, this diagnostic method has important role in treatment planning (both laser and surgical), i.e. tracking different retinal and optic nerve diseases.
Optical Coherence Tomography (OCT) is new, simple, non-invasive, contactless method of laser layered scan of retina and optic nerve.
