Khalil A. Khatri, Robert A. Lee, Lynne J. Goldberg, Beejul Khatri & Veronica Garcia, Journal of Cosmetic and Laser Therapy, March 2009
Based upon the thermal relaxation time of the hair follicle (10–50 ms), most lasers and light devices use relatively long pulse widths for hair removal. This study was conducted to evaluate a shorter pulsed, 0.65 ms Nd:YAG laser for hair removal. Methods: One half of each axilla of six female participants was treated and the other half was monitored as a control. The treatment sites were treated with a fluence of either 21 J/cm2 or 36 J/cm2 using an Nd:YAG laser with a wavelength of 1064 nm and a pulse duration of 0.65 ms. A manual hair count was done before treatment and at each follow-up visit. Results: Four months after four monthly treatments, the hair reduction was graded as 5 (75–100% reduction) on the high fluence side and 4 on the low fluence side (50–75% reduction) by individuals and investigators. The average hair count 4 months after four treatments in the sites treated with a high fluence went from 114 to 28 (76% reduction) and in the low fluence areas from 135 to 38 (72% reduction). Conclusion: This well-controlled study shows that a 0.65 ms Nd:YAG laser is effective and safe for hair removal.

OBJECTIVES To evaluate the safety and efficacy of a microsecond 1,064-nm neodymium-doped yttrium
aluminum garnet (Nd:YAG) laser for the treatment of facial telangiectasias.
METHODS Subjects ages 35–70 with Fitzpatrick skin types I to III and facial telangiectasias underwent two treatments with a micropulse (0.65 ms) 1,064-nm Nd:YAG laser. Treatments were spaced 30 days apart, with a final evaluation 60 days after the second treatment. Evaluation included digital photography and an assessment of the degree of improvement on a scale from 1 to 5 by the subject and a nontreating investigator.
RESULTS Twenty subjects (18 women, two men) with Fitzpatrick skin type II and III completed the study. The nontreating investigator rated the objective clinical response as total clearance (100% clear) in 10% (n = 2) of subjects, significant clearance ( ! 50% clear) in 75% (n = 15), and some clearance (0–49% clear) in 15% (n = 3). None of the subjects was rated as having no clearance or worsening. In terms of subjective clearance reported by subjects, 80% (n = 16) reported significant clearance, with the remainder reporting some clearance. No adverse events were reported.
CONCLUSION The micropulse 1,064-nm Nd:YAG successfully treated facial telangiectasias with a high degree of patient satisfaction, minimal discomfort, and no adverse events.
Laser Treatment of Onychomycosis Using a Novel 0.65-millisecond Pulsed Nd:YAG 1064-nm Laser
Lisa G. Hochman, Journal of Cosmetic and Laser Therapy, January 2011
Onychomycosis is a common disorder of the nails. Treatment modalities include oral and topical antifungals, surgical treat- ment or a combination of these therapies. Cure rates remain low with relatively high relapse rates seen after successful treatment. The purpose of this study was to evaluate the treatment of onychomycosis using a novel 0.65-millisecond (ms) pulsed 1064-nm laser. Eight subjects were treated over two to three sessions spaced at least 3 weeks apart. Of the eight subjects evaluated, seven had negative post-treatment cultures after the second or third session. Treatments were well toler- ated by all subjects. These data suggest that treatment of onychomycosis with a 0.65-ms pulsed Nd:YAG 1064-nm laser should be studied further to determine the long-term clinical and microbiologic effect. The optimal number of treatment sessions for each patient needs to be determined.
A Novel 0.65 Millisecond Pulsed 1064 nm Laser to Treat Skin of Color Without Skin Cooling or Anesthetics
Fran Cook-Bolden, MD, Journal of Drugs in Dermatology, December 2011
The Nd:YAG 1064 nm has become the gold standard laser modality for safely treating all skin types and specifically skin of color. The 1064 nm laser technologies with ultra long pulse durations generally require anesthetics as well as skin cooling in order for patients to tolerate the treatment. The use of anesthetics and gels can involve considerable time, cost and mess. The development of a new 1064 nm laser technology with a unique 0.65 msec pulse duration now enables virtually pain-free treatment of skin of color, with no need for skin cooling or anesthetics and no skin contact during treatment by the handpiece. This uniquely gentle, sanitary, and effective laser treatment experience for patients of color can increase the likelihood that they will return for follow-up treatment sessions and also recommend the treatment to others.
Laser Skin Resurfacing with a Novel Portable Erbium:YAG Laser
Khalil A. Khatri, James Gordon & Lalitha Garamela, Journal of Cosmetic and Laser Therapy, April 2006
Background and objective: The erbium:YAG laser is a popular modality for laser skin resurfacing (LSR). This study was performed to evaluate the safety and efficacy of a new portable Er:YAG laser in the treatment of photo-damaged skin. Methods: Nine patients with skin types I–IV were treated for rhytides, large pores, pigmented lesions, lentigines and photodamage. Small facial areas such as the periorbital area, nose, cheeks, and upper lip were treated with one to six passes at 5–6 J/cm2 with a new portable Er:YAG laser. Topical and local anesthesia was used. Results: All treated areas showed improvement and, depending upon the number of passes, re-epithelialization was complete within 2–7 days. The intense erythema resolved within 7 days and there was blending of treated and untreated areas within 2 weeks. Conclusion: The technique of applying a tailored number of 5–6 J/cm2, 300 ms pulses of a new portable Er:YAG laser to small areas appears to be safe and effective. There was minimal discomfort and a high level of patient satisfaction after a relatively short recovery time.
New Laser Technology Enhances a Podiatry Practice
Marc Garfield, DPM, Podiatry Management, April 2012
Laser therapy is not new to podiatry, but new technology is providing versatility and power that brings this type of therapy to a new level. Patients are increasingly attuned to the availability and popularity of laser treatments in general, and I have found it increasingly easy to attract patients for laser therapy. When I do, I always review oral, topical and laser treatment options with them in terms of risk and benefits, and the laser option fills a niche for an astounding number of patients that do not want pharmaceuticals or have failed oral and topical treatments in the past.
Erbium:YAG Laser Resurfacing Using a Novel Portable Device
James Gordon, MD, Misbah H. Khan, MD, Khalil A. Khatri, MD, Facial Plastic Surgery Clinics of North America, May 2007
Laser resurfacing of facial rhytids has become a popular treatment option for many patients who have wrinkles, photodamage, and acne scarring. Laser wavelength, pulse duration, and newer techniques continue to shorten the healing phase associated with laser skin resurfacing while maintaining clinical efficacy. Erbium:YAG laser resurfacing has emerged as one of the safer, more effective methods of facial rejuvenation compared with other modalities, such as carbon dioxide laser, with shorter recovery time and better treatment outcome.
The increasing popularity among physicians to use the Erbium:YAG laser for resurfacing has led to its widespread use; however, size and high initial and maintenance cost are among the problems with currently available laser devices. Additionally, because many cosmetic laser surgeons practice at more than one location, they are therefore faced with the challenge of using their laser devices at more than one office. The LightPod portable Erbium:YAG laser from Aerolase offers a new paradigm for more cost effective means of performing ablative resurfacing with reduced initial and maintenance cost and the ease of portability with significantly reduced size and weight.

James Gordon, White Plains, NY, and Khalil Khatri, Chelmsford, MA, Published at the 2006 Annual Meeting of the American Society of Ophthalmic Plastic and Reconstructive Surgery
The use of a portable 300 microsecond Erbium:YAG 2940nm laser for skin resurfacing, immediately following both bilateral upper and four eyelid blepharoplasty, was evaluated. Sixteen patients between the ages of 28 and 74 were treated for varying degrees of dermatochalasis and photo-damaged skin in the periorbital region. Eleven females and five males with Fitzpatrick Skin Types I-III were treated. Local anesthesia was administered on all patients Without sedation. All patients demonstrated dramatic improvement in the Appearance of ‘hoods’,‘bags’ and photo-damaged skin. Patients recovered from Ecchymosis and erythema within 14 days. The combination of blepharoplasty and skin resurfacing with a portable 300 microsecond Erbium:YAG laser appears to be a highly effective, patient-satisfying and safe modality to treat dermatochalasis and photo-damage. The additional 10-20 minutes of surgical time required for the skin resurfacing substantially enhances the outcome of the blepharoplasty.
Long-Term Hair Removal with a Novel 0.65msec Nd:YAG Laser
A Clinical Report by David J. Friedman, Jerusalem, Israel, April, 2008
A study was conducted in 2006/2007 to evaluate a pulsed Nd:YAG 1064nm laser for long-term laser hair removal. Unlike conventional lasers and light-based devices in the field, the laser in this evaluation utilizes a unique 0.65 millisecond pulse duration with no skin cooling, gels or anesthetics. Ten female subjects and one male subject with Fitzpatrick Skin Types II through VI were treated and the long-term results indicated >75% clearance in the majority of cases; those treated 5 to 7 times reported 82% clearance on average and as high as 93%. These assessments were made, on average, 8.3 months after the subjects’ final treatment session.
Full Closure of Foot Ulcers Using a Novel 0.65 millisecond Pulsed Nd:YAG 1064nm Laser
A Clinical Report by Dr. Juliette Hepburn, Nassau, Bahamas October, 2012
Common modalities for wound healing often fail to achieve full closure of a wound; however, new laser therapy using a novel 0.65msec pulsed Nd:YAG 1064nm laser (LightPod Neo, Aerolase, Tarrytown, NY) has previously demonstrated clinical success achieving closure in wound healing without making any contact to the wound. 1064nm laser energy has been clinically proven to stimulate the formation of new collagen in the dermis of the skin; the heat from a 1064nm laser is also theorized to stimulate bacterial destruction, Nitric Oxide production, and the wound healing cascade. A patient presented with ulcers on the distal areas of the feet, and was treated with the subject laser. The response to treatment was rapid. The patient reported no treatment discomfort at all. Both ulcers complete re-epithelialized in a short period of time (see additional data below). Patient satisfaction was very high. 10-month follow up was conducted on the ulcer that had been treated twice, and it was still fully closed with barely any visible evidence of where the ulcer had been.
Skin Tightening After Substantial Weight Loss, Using a Novel 0.65 millisecond Pulsed Nd:YAG 1064nm Laser
A Clinical Report by Pam Bennett, Douglas, GA, July 2012
A female patient presented with skin laxity in various anatomical sites, after losing 86 lbs over a 12-month period through diet and exercise. The patient initially received skin tightening treatments in the facial areas and arms with a 0.65msec pulsed Nd:YAG 1064nm laser (LightPod Neo, Aerolase, Tarrytown, NY); she was highly satisfied and then inquired about receiving the same treatment for skin tightening in the buttocks area. The laser treatment was well tolerated without any anesthesia or any form of skin cooling; the patient reported no treatment discomfort and no complications were observed. Mild erythema either didn’t appear at all, or resolved within a few hours after treatment. The effect of the laser treatments produced positive outcomes in terms of a noticeable reduction in the laxity of treated skin; the patient rated her satisfaction as Very High.
Combining Injectables with Laser Skin Rejuvenation in a Single Treatment Session, Using a Novel 0.65 millisecond Pulsed Nd: YAG 1064nm Laser
A Clinical Report by Yelena Kipervas, DO, & Tatyana Martinho, Bartonsville, PA, June 2011
This study was conducted to evaluate the safety of the use of a novel 0.65 millisecond pulsed Nd: YAG 1064nm laser for skin rejuvenation, when used in combination with injectables in a single treatment session. Seven subjects were enrolled and were treated with the laser first, then were given injections afterwards. It was observed that there was a reduction in the pain, bruising and swelling from the injections with the use of the laser prior to the injections. Patient satisfaction was High or Very High in all cases. The use of this laser and this protocol has the potential to increase client retention and to attract new clients who prefer less treatment discomfort and who prefer a single visit rather than two for skin rejuvenation.
Treatment of Active Acne and Acne Scars With a Single Laser Modality,
Using a Novel 0.65 millisecond Pulsed Nd: YAG 1064nm Laser
A Clinical Report by Yelena Kipervas, DO, & Tatyana Martinho, Bartonsville, PA, December 2011
This study was conducted to evaluate the use of a single laser modality to treat two skin conditions simultaneously: clearance of active acne, and reduction of acne scars. A novel Nd: YAG 1064nm laser with 0.65 millisecond pulse duration and a peak power of more than 15,000 watts per pulse was used. 10 subjects with skin type I-IV and an average age of 30 – 5 males and 5 females – were enrolled for the series of 3 treatments 2-3 weeks apart. The laser treatment was well tolerated with no anesthesia or any form of skin cooling. No complications were observed; subjects reported little or no treatment discomfort and a pleasant warming sensation as a result of the laser treatment. Of the 10 subjects, 8 rated their satisfaction as High and 2 rated it as Very High.
Complete Restoration of a Toenail Compromised by Onychomycosis, Using a Novel 0.65 millisecond Pulsed Nd:YAG 1064nm Laser
A Clinical Report by Boris Raginsky, DPM, Fair Lawn, NJ, June 2012
A male patient aged 74 presented with a toenail on the left foot that was affected by Onychomycosis and fully compromised. Laser therapy was selected because previous treatments by other modalities were not effective. The 1064nm laser modality has been proven to be effective in clearing Onychomycosis, as long as the pulse duration is in the submillisecond range and the fluence is at least 40-50 joules per square centimeter. Such a submillisecond Nd:YAG laser (the LightPod Forte laser from Aerolase, Tarrytown, NY) was used to treat this patient. The nail bed was cleaned and dried, and laser energy was applied at a spot size of 5mm, fluence of 41 j/cm2 and 0.6 millisecond pulse duration, with two complete passes applied to the full nail bed including the nail matrix area and surrounding skin. Two treatments were performed, spaced three months apart. A new, healthy and clear toenail grew in within 6 months after the first treatment session. No side effects were observed contact Aerolase for more information.
