Laser eye surgery
1) Pallikaris method exclusively in Knezović Polyclinic
Laser removal of diopter has been in the world since the late 1980s, and so far, dozens of millions of people were operated on this way. It’s a laser modeling of the shape and curvature of the cornea, i.e. frontal transparent part of the eye. Wavefront optimized Pallikaris method is one of the most reliable methods.
European cooperation of Professor Pallikaris and Croatian ophthalmologists
Prof. Dr. Ioannis Pallikaris is the pioneer and innovator of refractive surgery who performed the first LASIK procedure in the world in 1989. During his long-term ophthalmological career, he devoted himself to improvement of the method of laser vision correction that would allow the patient the highest vision quality and complete eye – safe procedure. Pallikaris’s micro brush is an innovation that has achieved world-wide recognized results and satisfied patients.
What is this about?
In order to access the laser modeling of the cornea using an excimer laser, it is necessary to firstly remove the upper, epithelial layer. This layer is removed mechanically in the conventional PRK method or with the help of 20% ethanol, what can be imprecise and traumatizing for gentle corneal tissue. In the Wavefront optimized Pallikaris method, a Pallikaris rotating micro brush is used to precisely remove the epithelium in just a few seconds.
Advantages of Pallikaris’s micro brush- state of the art technology in service of Your vision
This micro brush allows rapid and thorough removal of the epithelium without damaging the Bowman membrane and deeper layers of the cornea. The postoperative healing process is accelerated, with the completely reduced possibility of creating small blurriness in the cornea so-called “Haze”. The cornea heals more precisely because it has no negative mechanical effect or the effect of ethanol, with creating anatomically correct surface, which provides the best quality of vision. After removal of the epithelial layer, the state-of-the-art Laser Allegreto Wavelight 400Hz precision remodels the stroma of the cornea.
Pallikaris’s laser visual correction method proved to be the safest in the world’s eye clinics, it has gained the advantage over the LASIK method because it acts mildly on the tissue and leaves a thicker and more stable cornea, which is healing without any scar. After the procedure, it cannot be seen that the operation has ever been done.
The importance of quality preoperative processing
After a precise analysis obtained from the Pentacam analysis which we enter into the laser software, each patient is individually guided and adjusted specifically to the procedure in order to achieve the best result.
Advantages of Wavefront optimized laser vision correction
Allegretto Wavelight uses invisible ultraviolet (UV) rays in the size of 0.25 microns to remove extremely small parts of the corneal tissue to eliminate shortsightedness, farsightedness or astigmatism. The laser removes one diopter in 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 emission of the laser pulse only to a fully centered cornea, which ensures an extremely high degree of safety. Using the advanced Wavefront Optimized technology, it ensures exceptional reliability and high efficiency of the laser removal procedure of the diopter.
It has been established that this laser reduces the complications such as reflections and other night visual aberrations that may occasionally occur with conventional treatments. The whole procedure is painless, it is done in local anesthesia by the drops and it is finished in about 15 minutes. Thanks to the advanced laser technology that makes it possible to do a proper procedure, with special nomograms designed by many years of work and cooperation of Dr. Knezovic and the professional team of prof. Pallikaris, this safest method of laser visual correction is also possible to do in Zagreb.
2) Intralase LASIK – Revolution in laser vision correction
Intralase LASIK (Laser -Assisted in Situ Keratomileusis) is the most modern LASIK method of removal of diopters in the world.
It’s the only LASIK method for laser diopter removal approved by NASA for its employees!
This method uses a special femtosecond laser on the cornea to create a flap, which, after the laser modeling of the cornea shape, simply returns to its place. Unlike the classic LASIK method, everything is done entirely without the cutting of any surgical instruments.
The surgical procedure of laser removal of diopter is completely painless, lasts for about ten minutes and is performed ambulatory in local anesthesia (eye drops).
When does recovery occur and vision improve?
Improvements in visual acuity can be seen immediately after the procedure, and a day after surgery, almost normal visual acuity with smaller or larger variations is achieved. Vision recovers faster after Intralase LASIK method, then other methods of laser removal of diopter.
Returning to everyday activities
In femto-LASIK, both eyes are usually operated simultaneously and patients are able to return to their daily activities after 48 hours.
LASIK (Laser in Situ Keratomileusis) is the most common classic laser vision correction method with over ten million operations so far.
LASIK method is specific in that the upper, first layer of the cornea before ablation with the excimer laser is previously cut into the “flap” (slot or lid) by a precision device (microcromate) and move away so that the deeper layers of the cornea can be shaped by a laser.
PRK- laser vision correction method that has been applied since 1987. So far, over ten million people have been operated in the world with this method.PRK (Photo Refractive Keratectomy) is a method of laser removal of diopter in which the surface layer of the cornea (epithelial) cells is mechanically removed by alcohol, after which the laser is modeling the shape and curvature of the cornea, which corrects the visual defect.
LASEK (Laser-Assisted Subepithelial Keratomileusis) is a modified PRK where the surface layer of the cells is separated by alcohol, and after the laser, is brought back to the spot – for the purpose of faster recovery and minor subjective disturbances.
