Recommended Laser Beam Power for Lower Eyelid Skin Treatment with Alma Fraxel CO2 Laser
For treating lower eyelid skin with an Alma fraxel CO2 laser, use pulse energy of 25-35 J with a pulse duration of 1 ms, 200 μm spot size, and a density of 100 laser spots/cm² per pass, with 1-3 passes depending on severity of photoaging. 1
Optimal Settings for Lower Eyelid Treatment
Power and Energy Settings
- Pulse energy: 25-35 J
- Pulse duration: 1 ms
- Spot size: 200 μm
- Density: 100 laser spots/cm² per pass 1
- Number of passes: 1-3 (adjust based on desired skin contraction)
Important Modifications for Eyelid Skin
- For delicate eyelid skin, reduce energy settings compared to other facial areas:
- Use 250 mJ and 50 W for eyelid skin (compared to 300 mJ and 60 W used on other facial areas) 2
- Lower settings are crucial to prevent excessive thermal damage to thin periorbital tissue
Treatment Protocol
Pre-treatment Considerations
- Apply topical anesthesia before procedure 1
- Maintain oxygen concentration below 40% to minimize fire risk 3
- Keep a distance of at least 1 cm from target tissue to prevent charring 3
During Treatment
- Use multiple-pass, low spot density technique for controlled skin contraction 1
- Clean and debride tissue with normal saline between passes
- Continuous suction to remove smoke is mandatory 3
- Monitor skin contraction after each pass to determine if additional passes are needed 1
Post-treatment Care
- Apply semi-occlusive dressing for the first 5 days after surgery 2
- Follow with bland petrolatum ointment for an additional 5 days 2
- Finally, use moisturizer with sunscreen or bleaching cream as needed 2
Expected Outcomes and Considerations
Efficacy
- This protocol has demonstrated significant improvement in lower eyelid tightening:
- 40% of patients achieved 50-75% improvement
- 28% of patients achieved 75-100% improvement 1
- Results show improvement in both skin laxity and photoaging
Safety Considerations
- Potential complications include:
Clinical Pearls
- Control skin contraction: The fractional CO2 delivery allows immediate control of skin contraction during the procedure by adjusting the number of passes 1
- Avoid overtreatment: Using high energy with lower laser spot density provides better control than high density with lower energy
- Eyelid-specific caution: The thin skin of the lower eyelid requires reduced settings compared to other facial areas to prevent complications 2
- Monitor healing: Delayed epithelial healing may occur with certain underlying conditions 6
- Consider alternatives: For patients with significant skin laxity, transcutaneous blepharoplasty may be preferable to laser resurfacing alone 5
This protocol provides an effective balance between achieving significant skin tightening and photoaging improvement while minimizing recovery time and complications when treating the delicate lower eyelid area.
