Er:YAG lasers produce energy with a wavelength of 2940 nm, which is very near the 3000 nm peak absorption of water. Rarely, ablative laser resurfacing done near the lower eyelid can cause the eyelid to turn out and expose the inner surface. 1 Introduction . Less damage to the skin results in quicker recovery times. Some swelling may also occur. Therefore, adverse effects are to be expected and should be differentiated from complications. Erbium Yttrium-Aluminium-Garnet (Er: YAG): This ablative laser uses white metal, which eventually produces an infrared beam. – YAG lasers have a small Rayleigh length* vs. CO2, which has a longer Rayleigh length. This greater affinity allows for a cleaner target cell ablation with less thermal collateral cell damage. – YAG lasers have a higher-power density in terms of focusing light on one small area. Studies conducted before and after erbium laser resurfacing show that the procedure produces fewer complications and side-effects and minimal redness, swelling or bruising. without causing thermal side effects to the adjacent tissue (23-25). Even as erbium laser skin resurfacing provides a highly effective treatment for fine lines and wrinkles with a shorter recovery period and fewer side effects, those receiving treatment should still expect their skin to appear pink or red after the procedure. Unlike carbon dioxide lasers, erbium lasers tend to produce milder side effects. 9 ... without the side effects seen with older nonpulsed, continuous-wave carbon dioxide lasers. Its primary depth is within the papillary dermis where collagen tightening and neocollagenesis are achieved. Erbium is an ablative laser, meaning that it removes layers of damaged cells and heats the underlying dermis to trigger collagen production, tightening of skin, and smoother skin. Prolonged … Also known as Er:YAG, or Erbium laser for short, this technique is performed in a similar manner to other laser treatments. Examples include sealing leaking blood vessels, reducing pressure in the eye, replacing the cornea, and removing part of the iris. 2 M. Al-Dhalimi & A. Jaber 1540-nm erbium glass laser is absorbed efficiently by water, but minimally by melanin. results. This produces energy in the mid infrared invisible light spectrum which can be used to precisely target skin and water-holding tissue, leaving the surrounding skin unharmed. BACKGROUND Ablative laser skin resurfacing with carbon dioxide (CO 2) and erbium:yttrium‐aluminum‐garnet (Er:YAG) lasers has been popularized in recent years and their side effects individually reported.No prior study, however, has directly compared the relative healing times and complications rates between the two different systems. The procedure can also be used safely on areas where the skin is thin such as the neck, chest and hands. No prior study, however, has directly compared the relative healing times and complications rates between the two different systems. Turning of the eyelid (ectropion). However, the depth of penetration is lesser and the results are less visible with the same number of passes. Today, physicians use both carbon dioxide (CO2) lasers and erbium lasers. Side effects associated with Er:YAG and erbium laser resurfacing include erythema, hyperpigmentation, hypopigmentation, and scarring. Side Effects of CO 2-(Er:YAG) Laser Resurfacing and Dermatography as a Treatment. The inherent technological differences that exist between the two distant laser systems in terms of ablation depths, degree of thermal coagulation, and postoperative side-effects and complications guide patient selection and management. The head of the Spectrum Erbium YAG laser is held against your skin and moved slowly and carefully around the targeted area. After the laser treatment is completed, the area is wrapped for protection and to promote healing. Oral leukoplakia is one of the precancerous lesions identified by WHO. Risks and side effects of Er:YAG skin ablation For Er:YAG skin ablation basically similar early and late occurring side effects have to be considered as with dermabrasion or thermal laser damage of the same total depth of injury (46). Erbium YAG Laser vs CO2 Laser. Indeed, controlled clinical trial for SRP with Er: YAG laser has been performed and Er: YAG laser monotherapy showed almost equivalent clinical improvements compared to the conventional mechanical trial by hand instrument (26). Postoperative recovery was monitored and the rate of side effects and complications recorded. 3D volume-ablation rate and thermal side effects with the Er:YAG and Nd:YAG laser. If I had PDL with no side effects (other than purpura), what are the chances I'll have side effects from YAG? Side effects and complications were limited to transient hyperpigmentation and acne flare‐ups. CO2 laser resurfacing procedures produce extensive side effects, causing swelling, redness, and prolonged healing times up to 2 weeks. Average clinical grading scores reflected good to excellent response of atrophic scars to the dual‐mode Er:YAG laser system. The erbium:YAG laser is a 2940-nm ablative laser that targets intracellular water like the CO 2 laser does; however, its affinity for intracellular water is 10 times greater than that of carbon dioxide laser. No hypopigmentation or scarring was seen. It has a wavelength of 2940 nm and is effective for precision resurfacing as well as fractional treatments. 2 Because this wavelength has 10 times the water absorption of CO 2 lasers and a very short extinction, Er:YAG lasers deliver more efficient tissue ablation with minimal thermal damage, shorter recovery times, and lower incidence of side effects. Ablative laser resurfacing poses a slight risk of permanent scarring. The wavelength of the laser is 2,940nm and is absorbed much more efficiently by water in tissues than the CO2 laser. The most common procedure is a capsulotomy after cataract surgery. Side effects included a sensation of warmth and related mild‐to‐moderate pain in 4% of patients, as well as slight transient edema. At the Laser & Skin Surgery Center of New York, we use the Erbium YAG to treat fine lines, acne scars, surgical scars, and some pigmentation irregularities. Conclusion: ... Er:YAG laser, acne scars. As the laser destroys the outer skin layer, it heats up the lower layers, thus encouraging collagen production. • Significantly shorter healing time than CO2 lasers • Very few, if any, side effects • Safe and gentle treatments as well as deep ablation and skin resurfacing. Er:YAG laser resurfacing ablates superficial cutaneous tissue and imparts a thermal injury to denuded skin. Er: YAG laser had better effects than CO 2 laser in eliminating oral tumorous lesions while it needed longer operation time than CO 2 laser. In the estriol group, 8% of patients experienced spotting, 4% mastodynia, and 12% abdominal pain. June 21, 2011 . Compared to CO2 Fractional Laser, Erbium:yag laser at 2940nm wavelength, is a newer technique that decreases the thermal damage observed with CO2 laser, translating to a treatment that is safer for individuals with darker skin tones and with less downtime. Answer: GentleYag a good option for facial veins. The presumed mechanisms of char-free pulsed carbon dioxide laser rhytid improvement are epidermal ablation, dermal damage with collagen remodeling, and thermal contraction. Erbium laser skin resurfacing is a vigorous anti-aging and anti-blemish laser treatment that is able to effectively and powerfully rejuvenate, tighten, and balance the skin. The treatment does not destroy the skin cells completely, though the treatment is named as ablative. We conducted a study to verify the effectiveness of non-ablative vaginal erbium:YAG laser (VEL) treatment for patients with IC/BPS who were resistant to conventional treatments. Thank you! The Er:YAG laser settings varied from 250-400 mJ/pulse, 3-15 pps and 20-180 s processing time, and in the case of the Nd:YAG laser from 83-100 mJ/pulse, 10-20 pps, and 20-260 s processing time. From board-certified doctors and trusted medical professionals. A YAG laser can be used to treat several types of vision problems. significant side effects were noted. One of the laser resurfacing devices we use at PHI is the Erbium YAG laser. Erbium laser resurfacing is designed to remove surface-level and moderately deep lines and wrinkles on the face, hands, neck, or chest. iPixel YAG – Erbium – YAG laser has a shorter wavelength that equates to a lower level of penetration into the skin. Side effects and duration Healing usually takes between 3 and 10 days . Laser mainly uses its photothermal effect in treating oral tumor. -The Erbium laser: Yag at 2940nm. Patients were followed up at 1, 2 and 4 weeks and every month until 6 and 12 months post-treatment. One patient also developed transitory pain after laser treatment and one patient experienced spotting. These findings could be due to the fact that fractional Er-YAG laser provides less ablation and coagulation depth than fractional CO 2 laser, yielding comparable efficacy with lower downtime and less side effects . The Erbium YAG laser is manufactured by Continuum Biomedical. The zone of Er:YAG laser thermal necrosis is usually less than 30 to 50 mm. Erbium Yag is a non-ablative laser fractional technology employed to treat stretch marks, open pores, scars, saggy skin, wrinkles etc. The thermal effect can be modulated by varying the time (firing time = duration during which the energy is given). Nonablative laser resurfacing also can cause side effects, including: Infection. Answers (1)ASK A DOCTOR. 1 – 3. Erbium: YAG Laser Treatment Procedure; Side Effects; Benefits ; What is Erbium? Er: YAG laser can treat scars, fine lines and wrinkles with minimal damage to the tissue around the target area. The Erbium: Yag laser has an affinity for water 10 times higher, resulting in a nearly pure ablative effect (if very short times are used) by spraying the tissues. Minor adverse effects of cutaneous laser resurfacing include transient erythema, edema, burning sensation, and pruritus. Fraxel laser. Histologically, the effects of the laser has been studied and the depth of changes to collagen and elastic fibres ranged from 50-200 µm in the CO 2-treated specimens (average, 90 µm) compared with 30 to 50 µm (average, 45 µm) for specimens from Er:yag-treated sites. BACKGROUND Ablative laser skin resurfacing with carbon dioxide (CO2) and erbium:yttrium-aluminum-garnet (Er:YAG) lasers has been popularized in recent years and their side effects individually reported. Patients sometimes compare this experience to a sunburn. This study deals with the negative effects of CO 2-(Er:YAG) laser treatment used for cosmetic facial resurfacing. All patients underwent one session of MAL-PDT using a red light-emitting diode lamp at 37 J/cm(2) , and 23 patients with 135 AK lesions were randomly assigned to pre-treatment with a 2940-nm ablative fractional erbium:Yag laser. This procedure is used when clouding develops behind the lens placed after cataract removal. DermaBlate Erbium: YAG laser is one of the top-selling Erbium lasers in the world for the past 20 years and is the gold standard for dermatological treatments. Common therapies include drugs, excision, freezing, and laser. The side effects of this procedure are minimal compared to a CO2 laser, making it a preferred choice in ablative laser treatments.
