The use of a neodymium-YAG laser is described for opening the opacified posterior capsule in a pseudophakic eye. Both pigmented and nonpigmented ocular tissues were cut without causing adverse thermal effects and without opening the eye. The laser's instantaneous release of energy causes total ionization of the medium and formation of a plasma, followed by a hydrodynamic shock wave originating at the energy zone boundary. The temperature at the site of laser contact cannot exceed 2 x 10(-3) degrees C, which is not harmful to the eye. Further, this procedure requires no anesthesia and does not involve introduction of foreign material into the eye. The degree of aiming accuracy, the very small diameter of the laser beam (50 microns) and the use of selector pulses make the laser so precise that it virtually eliminates the risk of damage to the eye or the intraocular lens.
本文描述了使用钕钇铝石榴石激光打开假晶状体眼中浑浊的后囊膜。色素沉着和无色素沉着的眼组织均被切开，未产生不良热效应且未打开眼球。激光能量的瞬间释放导致介质完全电离并形成等离子体，随后在能量区边界产生流体动力冲击波。激光接触部位的温度不会超过2×10⁻³摄氏度，对眼睛无害。此外，该操作无需麻醉，也不涉及向眼内引入异物。瞄准精度、激光束非常小的直径（50微米）以及选择脉冲的使用使得激光非常精确，几乎消除了对眼睛或人工晶状体造成损伤的风险。
