Although the Nd:YAG laser is most commonly used to perform posterior capsulotomies after cataract surgery, it has also been used to treat a variety of other anterior segment abnormalities including tractional corectopia, iridocorneal adhesions, persistent pupillary membranes, and posterior synechiae. Numerous reports on the use of the Nd:YAG laser to treat structures in the anterior segment have emphasized the need to use higher pulse energy for pupillary membranes, compared with the lower settings required for posterior capsulotomy. Steinert and Puliafito noted that single pulses of 4 to 12 mJ may be required to treat pupillary membranes "in a manner similar to that of a stonemason chipping at marble" in their description treating a membrane considerably thicker than what we describe. We report the successful treatment of tractional corectopia due to an anterior membrane strand in a child with only 2 mJ of total energy.
虽然钕钇铝石榴石（Nd:YAG）激光最常用于白内障手术后进行后囊切开术，但它也被用于治疗多种其他眼前节异常，包括牵引性瞳孔异位、虹膜角膜粘连、永存瞳孔膜和虹膜后粘连。许多关于使用Nd:YAG激光治疗眼前节结构的报告强调，与后囊切开术所需的较低能量设置相比，治疗瞳孔膜需要使用更高的脉冲能量。斯坦纳特和普利阿菲托指出，在他们描述治疗比我们所描述的厚得多的膜时，可能需要4至12毫焦的单脉冲来“以类似于石匠凿大理石的方式”治疗瞳孔膜。我们报告了仅用2毫焦的总能量成功治疗一名儿童因前部膜条索导致的牵引性瞳孔异位。
