What is the RTVue system?
RTVue is a Fourier domain OCT system that can non-invasively reflect the retinal tissue live with high speed acquisition and high resolution scanning.
The first OCT system developed at the beginning of the 90’s was Time domain, which was based on the mechanical scanning method to obtain an in-depth signal of the tissue. The scanning speed is limited to 400 A-scan per second with conventional time domain OCT due to the mechanical movement obstacle. RTVue uses a camera to obtain the A-scan signals simultaneously without mechanical movement. The scanning speed of RTVue is 26,000+ A-scan per second; in other words, it’s 65 times faster than the conventional OCT system. To increase the scanning ratio, eye-movement based OCT devices have been eliminated from most* scan designs (*3D scanners with nearly 52,000 A-scans take 2 seconds to obtain the data – in some cases, movement devices are required).
The RTVue system also uses a high broadband light source. The tissue resolution is 4-5 micrometres – double the resolution of a convention OCT system. With the improved speed and resolution, RTVue provides a much more reliable and detailed map of the nerves with much quicker measurements.
RTVue Scanner:
This is the main component of the RTVue system. It is used to view and scan the patient’s retina, receive the OCT signal and send it to the computer for processing. It also features a fixation light system so the patient can stare at a fixed point during the scanning and a position sensor to automatically detect whether the patient’s eyes are correctly aligned for the scan. The scanner and computer communicate via a USB cable. RTVue uses a medical power supply.
Computer:
The computer is used to monitor the scan during the patient exam. The programme provides data analysis, data presentation and storage and generates files. A relational database is included to organize all patient information and all the data and it features a search system.
System desk:
The system desk provides power to the scanner, computer and computer screen via a medical grade isolation transformer that prevents power loss from the AC source. The height of the desk can be adjusted to the patient’s height. The telescopic system that supplies power to the RTVue is medical grade.
The Institut Oftálmic de Mallorca (IOM) has just acquired the sixth generation Amaris laser, becoming the first Balearic Island Ophthalmology Centre with this equipment.
Thus, the Institut Oftálmic de Mallorca is now the third leading centre in Spain after the Instituto Oftálmic Tres Torres of Barcelona and the VISSUM Hospital in Alicante.
It is a specially designed laser for refractive surgery (long sight, short sight and astigmatism); however, it can be used to treat irregular corneas and corneal scarring due to ulcers, decentrations of prior treatments and increase prior optical segments. It will also feature specific treatment for long-sightedness.
One of the main advantages of this equipment is the high speed treatment which combined with smart shot distribution control, reduces later corneal inflammation by 80%. Moreover, the small diameter of each shot which must less than other lasers makes it possible to achieve an extremely polished corneal surface.
Also advantageous are its 1050 Hz eye tracker - the largest by far on the market-, and its unique cyclotorsion control system. This means the eye can be perfectly monitored throughout the procedure.
The Institut Oftà lmic de Mallorca will carry out a campaign under the motto “Keep Your Eyes Safe" in order to spread knowledge of Amaris Laser on the Balearic Islands highlighting its reliability, accuracy and safety when it comes to vision correction.
The IOM has introduced refractive surgery at the Rotger Clinic with two new lasers – the IntraLase that produces the corneal flap (the first step) and the Amaris Laser which enables personalized treatments and treatments for ocular aberrations (second step). In this manner, the IOM will achieve excellent results on Mallorca in these refractive surgery treatments.

The IOM is incorporating the new Carl Zeiss next generation aspheric cataract lenses - - XL-STABI ZO-, which provide high visual quality that is much greater than other lenses that have been used to date. More information
