Figure 8 Xanthelasma removal


ptosis, entropion and ectropion, and xanthelasma excision are discussed in this article. Reduced operation time, less bleeding, superior intraoperative visibility, less bruising and swelling, as well as less pain and discomfort, and a shorter healing period, are some of the benefits of using the laser as a surgical tool. Furthermore, the CO2


laser can be used in laser


resurfacing treatments for photodamaged skin and acne scars. The efficacy and safety have been demonstrated with this technique since its first introduction 20 years ago. Thermal ablation vaporises superficial layers of tissue providing the tissue rejuvenation.

Reduced operation time, less bleeding, superior


intraoperative visibility, less


bruising and swelling, as well as less pain and discomfort, and a


shorter healing period, are some of the benefits of using the laser as a surgical tool.


In the author’s clinic the use of the CO2 laser is not


limited to skin resurfacing, but is also used in laser- assisted blepharoplasty procedures (Figures 2–5) as a bloodless incisional modality is preferred. This treatment modality is easier, and better results can be achieved by using the CO2


laser in the majority of eyelid


surgeries such as ptosis, ectropion and entropion, and in xanthelasma (Figure 8). A 0.2 mm laser handpiece with an 8 W setting is used


in incisional surgeries. Additionally, the handpiece is used at normal focal length to incise the skin and orbicularis, as well as the septum, while for melting and reshaping of the fat tissue it is preferred to de-focus the laser in order to increase the spot size to shrink fat. Although the laser is excellent for small-vessel haemostasis, it is less valuable for larger-vessel haemorrhage, as the CO2


chromophore is water and


the small beam loses its ability to coagulate in a pool of blood. For lower-lid surgery, it is possible to use both the


transcutaneous or transconjunctival approach. If the latter is used, the conjunctiva and capsulopalpebral fascia are incised to access the prolapsed lower fat pads. The incision is made approximately 4 mm inferior to the lower tarsus from the canthus to the lacrimal punctum. A subciliary incision is made if the transcutaneous method is preferred. In some patients upper-lid blepharoplasty with lower-lid resurfacing is performed, providing very good results (Figures 3–4). However, it is essential to select patients carefully as laser resurfacing should not be performed if there is laxity at the lower eyelid, as this will increase the risk of post-surgical ectropion.

activation causes immediate tissue contraction and new collagen production to reduce wrinkles and tighten the skin. Patient


appropriate


selection and preoperative


planning and postoperative care are essential for successful outcomes and unwanted side-effects. Despite the advances in


technology and the introduction of alternative methods for skin resurfacing, the CO2


laser continues to deliver the


most consistently effective improvement in skin tightening and wrinkle reduction, thus remaining the gold standard for skin resurfacing.
