Iridex® MicropulseTM Technology Explained using Computer Animation

Carleton Ltd, the exclusive distributor of Iridex lasers and delivery devices in the UK, has introduced a new educational animation video that helps to explain the benefits of Iridex Micropulse technology. This new video clip, produced by Iridex as part of their 20th anniversary celebration, is available in both a 5 minute version for medical professionals and a 2 minute clip for patients.

MicroPulse is a laser delivery modality that adds finer control of photothermal effects in laser photocoagulation. Using MicroPulse for laser trabeculoplasty (MLT) offers a tissue-sparing technology for the reduction of intraocular pressure. Unlike conventional laser trabeculoplasty procedures, there is no destructive, coagulative damage to the meshwork.

Used in the retina, MicroPulse settings extend the aspects of tissue-sparing applications to treatments otherwise performed with conventional photocoagulation. DME, CSR, and even PRP are areas where MicroPulse technology can be utilized.

In conventional photocoagulation, the temperature rise for an intended intraoperative endpoint is controlled by adjusting the power and the exposure duration of the continuous-wave (CW) laser emission. With MicroPulse, the steady CW emission is “chopped” into a train of short laser pulses, whose “width” (“ON” time) and “interval” (“OFF” time) are adjustable by the surgeon. A shorter MicroPulse “width” limits the time for the laser-induced heat to spread to adjacent tissues, thus providing fine control of energy delivered. A longer MicroPulse “interval” between pulses allows cooling to take place before the next pulse is delivered.
