Infiniti Vision System
Infiniti is a product of the American company Alcon, a leader in the production and distribution of ophthalmic surgical equipment and medications. It represents a step forward in the evolution of phacoemulsification devices, that is, devices for ‘breaking up’ and removing the natural lens, and allows the surgeon easier use with a lower chance of intraoperative complications. The phacoemulsification process begins by introducing into the eye a probe whose titanium tip vibrates at ultrasonic frequencies (40 000Hz) and in this way breaks up the natural lens. The lens fragmented in this way, that is, its nucleus and cortex, is aspirated using irrigation-aspiration probes.
Comfort and fast recovery
Unlike extracapsular cataract extraction, which requires a large incision in the cornea or sclera (from 10 to 12mm) that has to be closed with sutures, the phacoemulsification procedure is performed through a much smaller incision that heals very quickly on its own after surgery, without the need for suturing. Phacoemulsification is the most common procedure for extraction of the clouded lens (cataract) in developed countries, and we are pleased to be able to offer our patients cataract surgery at a world-class level, where the patient’s comfort and their fast and easy recovery come first.
Torsional ultrasound technology
INFINITI Vision System stands out from other phaco machines because it introduces into the phacoemulsification process the special ‘OZil Torsional’ probe, the INTREPID PLUS fluid management system (FMS), easier use of the console itself by the surgical staff based on touch-screen technology, etc.
The OZil torsional probe is a unique phaco instrument in terms of ultrasonic oscillation from side to side, which gives it a lens-cutting effect, resulting in more efficient emulsification of the lens material and reduced trauma to the surrounding ocular structures. Unlike the OZil probe, traditional ultrasonic phaco machines work on the principle of a ‘pneumatic hammer’, where the tip of the probe oscillates up and down and strikes the lens, breaking it in this way, which can lead to greater trauma to the eye if stronger ultrasound power has to be used because of the hardness of the cataract.
Optimal postoperative results
The cutting effect speeds up the process of extracting the lens material many times over and reduces the possibility of dispersion of lens fragments into the anterior chamber or behind the iris, which is also more common with traditional ultrasound devices. In addition to proven efficiency in surgery, due to the lower temperatures at which the probe operates, the safety of the eye from thermal injury is ensured. The OZil torsional probe is made of titanium, is easy to handle and allows optimal delivery of energy that matches the surgeon’s technique and the individual needs of each patient. It provides the surgeon with greater control during the operation itself, resulting in safe surgery and better postoperative results. The surgeon has at their disposal the use of ultrasonic torsional oscillation, traditional ultrasound, or a combination of both profiles.
The software of the phacoemulsification device monitors the situation throughout the entire cataract surgery, informs the surgeon with visual and audio signals about every new change, and enables them to respond to each one quickly and efficiently. The transmission of ultrasound energy and the fluids/solutions that irrigate the anterior chamber of the eye through the probe are also under constant control so that the intraocular pressure remains within physiological ranges. The ultrasound energy can be decreased or increased according to the surgeon’s needs.
