Various methods have been used in the treatment of trichiasis: epilation, excision, cryosurgery, thermocaustic needle, and argon laser. None of these is satisfactory. Based on the principle of selective photothermolysis for destroying specifically the hair follicle, we used a diode laser and evaluated its efficacy.
Nineteen eyes with 301 itching lashes were treated in three sessions at intervals of 1 week. In each session the single hair follicle received laser energy of 20 J/cm2 at a frequency of 806 nm for 15 ms. We used a bare fiber of 0.8 mm at a distance of 2 mm from the follicle.
After 4 months two-thirds of the hairs were destroyed. The regrown lashes, however, are lighter and softer than the original ones. This treatment is less painful than all others. The laser is small, easy to use, and inexpensive.
The diode laser is a useful tool for the treatment of trichiasis. The laser parameters, however, should be ameliorated.
倒睫的治疗方法多种多样,包括拔毛、切除、冷冻手术、热灼针和氩激光治疗。但这些方法都不尽人意。基于选择性光热解原理,即特异性破坏毛囊,我们使用了二极管激光并评估其疗效。
对19只眼睛的301根瘙痒睫毛进行了3次治疗,每次间隔1周。每次治疗时,单个毛囊接受波长806nm、能量密度为20J/cm²、脉宽15ms的激光照射。我们使用一根0.8mm的裸光纤,距离毛囊2mm。
4个月后,三分之二的毛发被破坏。然而,重新长出的睫毛比原来的更轻、更软。这种治疗比其他所有治疗方法的疼痛都要轻。该激光体积小、易于使用且价格低廉。
二极管激光是治疗倒睫的一种有用工具。然而,激光参数应加以改进。
