2 The Cutera GenesisPlus is an Nd:YAG (1064 nm) laser with a patented pulse structure designed for safe and effective treatment on all skin types and tanned skin. It can be safely used on all body parts (excluding the eye and surrounding area). Common indications include: Clearance of nail with Onychomycosis / Nail Fungus Warts Scar reduction: including reduction in hypertrophic and keloid scars Improvement in texture Reduction in pore size Wrinkle reduction Rosacea / Diffuse Redness Poikiloderma of Civatte Morton s Neuromas PREREQUISITE The GenesisPlus device should only be operated by qualified practitioners who have received appropriate training and have thoroughly read the GenesisPlus Operator Manual (shipped with laser) and reviewed the GenesisPlus Training Presentation (found on Cutera VIP website) prior to operating the laser. PATIENT ASSESSMENT This is a medical device. It is important to obtain a complete medical history and signed informed consent. Consult the Operator Manual for additional information, including expected transient events and possible adverse events. Determine ethnicity and skin type by using the attached Fitzpatrick Skin Type scale Contraindications: Pregnancy and patients undergoing treatment for skin cancer Patient Considerations including but not limited to are below: Current Medications (both routine and occasional use) o Accutane do not treat if taken in the last 6 months o Gold Therapy may cause blue-gray discoloration o Anticoagulants may increase risk of purpura or bruising Vitiligo may cause de-pigmentation Herpes pre-treatment with an antiviral may be indicated Open wounds Diabetes may impede wound healing Neuropathies decreased sensation or numbness o Treatment area should be evaluated for numbness or decreased sensation History of keloid or hypertrophic scarring Tan skin and darker skin types have an increased risk of complications and/or pigmentary issues. Parameters may need to be adjusted to help prevent adverse events. No self-tanners, spray tans, etc. for at least 2-4 weeks prior to treatment Do not treat questionable skin lesions. These should be evaluated by a specialist prior to treatment. o Online Melanoma resources include ( ( April 2013 D1074 Rev. G p. 2

3 TEMPERATURE MONITORING GenesisPlus features a temperature sensor which monitors average temperature over a larger treatment area when handpiece is approximately 4cm from the tissue The temperature in Celsius will be displayed on the screen with the colored lights on the handpiece corresponding to that temperature Can be used as an indicator of bulk heating o Bulk heating is usually achieved at o C (Yellow LEDs) LED Color Green Green Green Yellow Yellow Red Temp Range o C o C o C o C o C o C POSITIONING THE HANDPIECE When performing rejuvenation, scar or Onychomycosis treatments, position the handpiece approximately 4cm above the treatment area maintaining that distance during the entire treatment Ensure that the smaller working distance beam is centered in the larger aiming beam The temperature sensor will not be visible Visible aiming beam Invisible Temperature sensor Visible working distance beam GOGGLES Safety eyewear must be worn by ALL people in the treatment room. o Check the wavelength and optical density 1064nm) marked on all operator goggles o Patients can opt to wear Operator Goggles during off the face treatments Operator Goggles Patient Goggles SELECTING PARAMETERS The recommended parameters are provided as a guide and are based on practitioner feedback. Fluence is the energy measured in J/cm2 o Fluence may need to be lowered for areas with increased target Pulse Duration or Pulse Width is the length of each laser pulse measured in milliseconds (ms) o Shorten pulse duration for more aggressive treatments o Lengthen pulse duration for more conservative treatments Repetition Rate is the number of pulses per second measured in Hz o Repetition rate may need to be lowered for increased patient comfort April 2013 D1074 Rev. G p. 3

4 ONYCHOMYCOSIS / NAIL FUNGUS PERFORMING THE PROCEDURE Avoiding Complications Anesthetics or nerve blocks are not recommended as patient feedback is required Patients with neuropathy may not be able to provide feedback o Increased risk of adverse events Do not treat over or close to tattoos Implants o Reaction to metal implants is unknown o Pacemaker - stay at least 6 inches away from implant Prepping the Patient Remove nail polish and clean toes/fingers Remove or cover any jewelry (including toe rings) Clean all nails thoroughly Shave the treatment area if there is excessive hair Topical anesthetic should not be used as patient feedback is required If nail is thicker than 2mm, the nail may be debrided o Smoke evacuator & laser plume mask filtered to 0.1 microns are recommended when debriding Nail may be notched with a file to assess growth of clear nail Pre-treatment photographs should be taken prior to the initial treatment for future reference Safety eyewear must be worn by ALL people in the treatment room Recommend that laser operator follow Universal Precautions (gloves, masks, etc.) Smoke Evacuator and/or laser plume masks filtered to 0.1 microns are optional during laser treatment Selecting Treatment Parameters Start with slow repetition rate for patient comfort and adjust to patient tolerance Spot Size Skin Type 5mm Fluence Pulse Duration Repetition Rate # Treatments I-IV J/cm2 0.3 ms 2 3 Hz 1-5 V-VI J/cm2 0.3 ms 2 3 Hz pulses per toe using multiple passes 600+ pulses using multiple passes May need additional pulses for severely infected or larger nails. Target Minimum Total Pulses Hallux/Thumb Toes/Fingers 400+ pulses using multiple passes Toes 1,000+ per foot per toe Fingers 1,200+ per hand per finger 200+ pulses per finger using multiple passes April 2013 D1074 Rev. G p. 4

5 Performing the Treatment Gel is not used Nerve blocks are not recommended as patient feedback is required Treat the entire nail bed, matrix and lateral folds, extending approximately 2mm Matrix or past the nail Proximal nail fold Hold the handpiece perpendicular to the nail s surface o Ensure the distance beam is centered in the aiming beam (approximately 3-4 cm from target) Treatment Technique: o Pulses should be adjacent Adjacent pulses should be of the larger aiming beam, NOT the smaller distance beam o Do not stack pulses (one pulse directly on top of another with no cooling time) or overlap pulses o Alternate between vertical and horizontal passes with each pass o Movement should be controlled and Repetition Rate adjusted according to the Incorrect Technique patient s tolerance Treatment Steps: o Start treatment on the hallux (big toe) or thumb moving onto adjacent toes/fingers o Use multiple passes until the recommended number of pulses has been delivered o Repeat either sequence until the recommended number of pulses have been delivered Correct Technique Treat each toe/finger to point of discomfort, then move to the adjacent toe/finger OR Treat hallux/thumb with pulses at a time then move to smaller toes/fingers with 25 pulses per digit at a time. o The number of passes may change from patient to patient depending on patient tolerance Distance Laser Beam o It should be noted that the pain tolerance lowers with each pass Beam (treatment area) o Pause treatment for 5-10 seconds in between passes for patient comfort o White flashes or sparks can occur during treatment It is recommended that all 10 toes/fingers be treated Endpoint for treatment is number of pulses o Though the goal temperature is NOT the endpoint, it can help indicate if enough heat is being delivered to the tissue. Post Operative Care To help prevent re-infection: o Wear clean shoes/socks home after treatment o Wash sheets, disinfect shower/bath and vacuum carpets day of treatment o Apply anti-fungal cream 2X per day for approximately 2 weeks to 3+ months depending severity of the infection o Apply anti-fungal powder to all shoes at least 1x per week for at least 1+ month o Keep nails trimmed and cleaned (disinfecting instruments after each use) o Do not walk barefoot in public places (pool, gym, etc.) Nail polish may be applied 24 hours after treatment Number of treatments will depend on severity of the Onychomycosis / Toenail Fungus o The average time interval between treatments is 4-6 weeks Due to slow nail growth, results may not be noticeable for 3+ months o Toenails may take months and fingernails may take 6-9+ months to grow out Severely infected nails may take longer If a blister develops, treat as a wound Cold gel packs or cool compresses may be applied post-treatment on hot spots April 2013 D1074 Rev.

6 MORTON S NEUROMA PERFORMING THE PROCEDURE Treatment Description GenesisPlus can be used to relieve the symptoms of Morton s Neuromas, a painful and often chronic condition with limited options for pain management. Avoiding Complications Topical anesthetics or local anesthetics should not be used as patient feedback is required Patients with neuropathy may not be able to provide feedback o Increased risk of adverse events Do not treat over or close to tattoos Possible hair loss may occur Reaction to metal implants and fillers is unknown Prepping the Patient Clean entire treatment area (including in between toes) ensuring any lotion, lint, dirt, etc. is removed Shave the treatment area if there is excessive hair Remove or cover any jewelry in treatment area such as toe rings Pre-treatment ultrasound can be conducted prior to the initial treatment for future reference Recommend that laser operator follow Universal Precautions (gloves, masks, etc.) Safety eyewear must be worn by ALL people in the treatment room o Check the wavelength and optical density 1064nm) marked on all operator goggles Selecting Treatment Parameters Start with low fluence and slow repetition rate to observe laser-tissue interaction Adjust fluence and repetition rate to patient tolerance Sensitive areas, darker skin types, areas of dense hair or recent sun exposure may require lower fluence or slower repetition rates Skin Type Spot Size Fluence Pulse Width Repetition Rate Number of Treatments I-IV 5 mm J/cm ms 5 10 Hz 2-10 V-VI 5 mm J/cm ms 5 8 Hz 2-10 Dorsal delivery of pulses followed by Plantar delivery of pulses is typical April 2013 D1074 Rev. G p. 6

7 Treatment Technique Gel is not used Topical anesthetics should not be used as patient feedback is required o Patients should experience heating to a warm to hot, but not painful level Hold the handpiece approximately 3-4 cm from the skin s surface o Ensure the distance beam is centered in the aiming beam Plan to treat in a line over the neuroma starting from between the toes on either side of the neuroma extending distally to 2-3 cm beyond the neuroma The handpiece should be moved continuously with an even distribution of pulses o Movement should be controlled with the speed adjusted according to the repetition rate and patient s tolerance The handpiece should be moved in a paintbrush style backwards and forth along the treatment line first over the neuroma and then extending slightly to either side of the neuroma Pause treatment after every 3 to 5 passes, when the temperature peaks between 42 C - 46 C or when the patient reports moderate discomfort and massage neuroma for 5-10 seconds o If needed, slow the repetition rate for patient comfort o Continue until the desired numbers of pulses have been delivered The temperature indicator should be monitored during treatment to ensure that optimal temperatures are achieved, however; the endpoint is determined by the total number of pulses delivered not intraoperative treatment temperature Depending on the user setting, the laser emits a distinct water drop sound every 25, 100 and 500 pulses or every 100, 1000 and 5000 pulses o These sounds can help keep track of treatment progress without looking at the screen Dark skin, scars or hot spots may require cooling or more pauses during the treatment Post-Operative Care No special post-operative care is typically required Erythema is normal and expected and resolves with time Edema is a normal reaction Average treatment protocol is 6 to 10 treatments, weekly or twice a week depending on severity. While some patients have reported improvement and relief after 1 treatment, most will typically begin to feel relief after 2 to 3 treatments If a blister develops, treat as a wound Cold gel packs or cool compresses may be applied post-treatment on hot spots It is recommended that patients avoid tight shoes, high heels, running and high impact aerobics during their treatment regimen Markings showing typical treatment area for a patient with a neuroma Correct Handpiece Technique Massaging treatment area April 2013 D1074 Rev.
