LUTRONICÕS CLARITY: A VALUED VERSATILITY
Lutronic discusses the value, reliability and efficacy that its versatile CLARITY can offer
P
ROVIDING PRACTITIONERS WITH TWO workhorse wavelengths on a single easy- to-use system, CLARITY from Lutronic Corporation is emerging as one of the most versatile dual-wavelength platforms on the market. The device harnesses the
power of the well-understood 755 nm Alexandrite laser and the 1064 nm Nd:YAG wavelengths — separately or in conjunction — for a growing list of common indications, such as benign pigmented and vascular lesions, skin lifting and rejuvenation, and laser hair removal. With a variety of available spot sizes, adjustable treatment parameters and choice of cooling methods, doctors can safely and successfully treat conditions in patients of any skin type. Owners also count on the reliability and value associated with Lutronic systems in general. CLARITY features CE Mark and KFDA clearances, with US FDA clearances pending.
A successful system CLARITY’s success starts with its laser wavelengths. When considering absorption spectra, the 755 nm Alexandrite laser has demonstrated higher absorption for melanin and oxyhaemoglobin when compared with the 810 nm diode laser. The 1064 nm Nd:YAG laser is known for its penetration depth, absorption by oxyhaemoglobin, and higher absorption by water. Thus the two wavelengths are distinct and complementary, for maximum versatility. Additionally, the device’s top hat beam profile provides more uniform, consistent delivery of energy of either wavelength for more predictable treatment outcomes. The laser energy is delivered using a single

lens-coupled optical fibre that does not require changing, even when switching between any of the system’s nine spot sizes. Each handpiece cartridge is a tip that delivers a different spot size ranging 2–20 mm in diameter, with no limitation by wavelength, meaning that all spot sizes are available for either wavelength. System software automatically senses which tip is attached, making the transition between spot sizes rapid, easy and seamless. Larger spot sizes are excellent for rapid laser hair removal or skin rejuvenation and lifting. Smaller spot sizes provide precision options for vascular and pigmented lesions, or any treatment

requiring precision due to anatomical size restrictions. The device itself is remarkably well engineered.
Adjustable treatment parameters include fluence, pulse width, and pulse rate. Maximum pulse energy output with the Nd:YAG is 100 J, with the top end of the Alexandrite fluence at 55 J. Maximum total fluence is 600 J/cm2
. Notably, low fluence options are available
with small spot sizes for gentler treatment, which is especially important when treating some types of pigmented lesions. Additionally, pulse width can be modulated between 0.35 ms and 300 ms; pulse rate can be adjusted between 0.5 and 10 Hz. As a result, treatment can be customised for each patient, including those of darker skin types.
Clinical trials Professor Chong-Hyun Won of ASAN Medical Center in Seoul, South Korea, carried out a clinical trial with CLARITY to compare the photoepilatory efficacy of long pulsed Alexandrite with that of IPL in the removal of axillary hair in 13 Korean women. The primary objective of this study was to evaluate any differences between the two systems with regard to efficacy, patient satisfaction and rate of side-effects. This study was a intra-patient, right–left, assessor-blinded comparative study of axillary hair removal comparing the Alexandrite laser with IPL. The long pulsed Alexandrite settings used had an output wavelength of 755 nm and the parameters used were 3 ms pulse duration, 10–15 J/cm2
fluence, and 15, 18 and
20 mm round-spot cartridges. The optionally-available cryogen spray system (Intelligent Cooling Device, ICD) was used on all patients for epidermal preservation with 20 ms pre-spray and 10 ms delay. In this study, at 8 weeks post-treatment, hair reduction
was 86% and 96% in sides treated with IPL and Alexandrite laser, respectively. The results showed that both systems are effective; with the Alexandrite laser shown to have resulted in more significant reduction of axillary hair than IPL. Patients reported higher levels of satisfaction for the Alexandrite laser when compared with IPL. Despite the higher pain score reported with laser treatment, more patients preferred the Alexandrite laser treatment. The study was supported by the Korean Health Industry Development Institute (KHIDI).
