Iridex's Patented MicroPulse® Laser Therapy

MicroPulse allows the tissue to cool between laser pulses, minimizing or preventing tissue damage. Treatment risks are reduced or eliminated, with increased patient comfort than with conventional, continuous-wave laser treatment.

Micropulse before and afters

MicroPulse® laser therapy is a tissue-sparing solution for the treatment of retinal diseases and glaucoma. With MicroPulse, a continuous-wave laser beam is chopped into a train of short, repetitive, low energy pulses separated by a brief rest period which allows the tissue to cool between laser pulses.

MicroPulse laser therapy is an essential asset for a comprehensive practice. We invite you to watch our webinars or to read this article from MicroPulse experts Drs. Friedrichs, Phillips, and Mahootchi to learn the reasons and benefits of incorporating MicroPulse into your practice.

 

 

 

Glaucoma

Introducing the New MicroPulse P3® Glaucoma Device (MP3) that performs innovative Cyclophotocoagulation with MicroPulse Technology Powered by the New CYCLO G6™ Glaucoma Laser System.
Learn How

MicroPulse laser trabeculoplasty (MLT) is a tissue-sparing laser therapy intended to reduce intraocular pressure. Unlike conventional laser trabeculoplasty procedures, there is no destructive, coagulative damage to the trabecular meshwork.
Learn How

Retina

MicroPulse settings extend the aspects of tissue-sparing applications to treatments otherwise performed with conventional photocoagulation. DME, CSR, and even PDR are areas where MicroPulse laser therapy can be utilized.
Learn How

MicroPulse® is a laser delivery modality that adds fine control of photothermal effects in laser photocoagulation. 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.

 

 

MicroPulse (low duty cycle). Very little thermal spread can occur due to the extended "OFF" time between each MicroPulse. Tissue is allowed to return to baseline temperature before the arrival of the next pulse.

 

MicroPulse (medium duty cycle). Doubling the "width" of the pulse, doubles the energy deposited, increases the heat spread during the "ON" time, reduces the cool off time, but can still avoid cumulative thermal build-up.

 

MicroPulse (high duty cycle). More energy is deposited with more thermal spread during the “ON” time and some thermal build-up due to the shorter cool off time before the next pulse.

 

CW Pulse (100% duty cycle). The thermal rise and re-equilibration can only be controlled by adjusting the power and the exposure duration of the CW laser emission.

Outcomes of Micropulse Transscleral Cyclophotocoagulation in Uncontrolled Glaucoma Patients

Glaucoma is the leading cause of irreversible blindness worldwide, with >70 million people affected and ~10% becoming legally blind during their lifetime. According to current evidence, glaucoma is defined as a group of optic neuropathies manifesting as progressive degeneration of the retinal ganglion cell layer, with consequent optic disc remodeling and cupping, and ultimately irreversible visual field loss. This study aimed at evaluating the intermediate-term efficacy and safety of micropulse transscleral cyclophotocoagulation (MP-TSCPC) in cases of uncontrolled glaucoma.

 

Laser resensitization of medically unresponsive neovascular agerelated macular degeneration: Efficacy and Implications.

Subthreshold diode laser micropulse was performed in 13 eyes unresponsive to all anti-VEGF drugs despite at least 4 consecutive anti-VEGF injections given for more than 4 to 6 months, including at least 3 consecutive ineffective aflibercept injections given 4 to 6 weeks apart. After monthly aflibercept was resumed 1 month after MicroPulse, 92% (12 of 13) of eyes improved, with complete resolution of macular exudation in 69% (9 of 13). Visual acuity remained unchanged. Central and maximum macular thicknesses significantly improved. Subthreshold diode micropulse laser treatment restored drug response in drug tolerant eyes with neovascular age- related macular degeneration.

Subthreshold laser therapy for diabetic macular edema: Metabolic and safety issues

A review of the literature about the mechanisms of action and role of MicroPulse diode laser in DME was conducted. The authors conclude that MicroPulse is a new, promising treatment option in DME, with both infrared and yellow wavelengths using the less aggressive duty cycle (5%) and fixed power parameters. It appears to be safe from morphologic and functional point of view in mild center involving DME.

Nonvisible subthreshold micropulse diode laser (810 nm) treatment of central serous chorioretinopathy. A pilot study

A prospective study of 24 eyes, with CSC for more than 3 months with no prior intervention, were treated with nonvisible MicroPulse laser. Mean follow-up was 14 months (mean, range 3 to 36 months). Authors’ conclusions: The majority of eyes achieved anatomic and functional improvements. MicroPulse is a new and promising method for treating a previously untreatable disorder. This minimally invasive and retina sparing treatment may allow the cure of CSC at its earlier stages when irreversible visual loss has not occurred
