钕钇铝石榴石脉冲式激光(Nd-YAG)可应用于晶体手术前的前囊切开、晶体的碎化、以及在植入人工晶体后后囊混浊的切开。所有眼部组织,不论有无色素、混浊或透明均能切割,而不产生危险的热效应。1978年以来,在Trousseau治疗人数已超过500例,用于睫状膜的切开、虹膜切除、继发性外伤性白内障、滤帘切除、房角切开。原理:基本原理与创新的装配是:产生一个等离子区的保护屏障,增加激光冲击波的机械性效果,而不致使房水、玻璃体、角膜或视网膜受热。事实上房水温度明显上升可引起色素膜反应、角膜水肿、即刻或延迟发生内皮萎缩;在无晶体眼,玻璃体过热可引起收缩及索条,导致视 Neodymium Yttrium Aluminum Garnet Pulsed Laser (Nd-YAG) can be used for anterior capsulotomy, crystalline fragmentation, and incision of posterior capsular opacities after implantation of an intraocular lens. All eye tissue, whether pigmented, cloudy or clear, can be cut without creating dangerous thermal effects. Since 1978, more than 500 patients have been treated in Trousseau for incision of the ciliary membrane, iridectomy, secondary traumatic cataracts, filter curtain, and angle cut. Rationale: Fundamentals and innovative assembly are: Produce a plasma barrier and increase the mechanical impact of laser shock waves without heating the aqueous humor, vitreous body, cornea or retina. In fact a marked increase in aqueous humor temperature can cause pigment reaction, corneal edema, immediate or delayed endothelial atrophy; in aphakia, vitreous overheating can cause contraction and cable, resulting in visual
