2024年10月10日 · A YAG laser capsulotomy is a type of laser eye surgery that uses a Yttrium-Aluminum Garnet (YAG) laser to improve a patient’s vision after cataract surgery.

What Is a Posterior Capsulotomy? A YAG laser posterior capsulotomy is a procedure done to help remove scar tissue after you’ve had a lens replacement. Inside your eye,...

2022年6月29日 · Neodymium:YAG lasers (commonly called Nd:YAG) are non-ablative, meaning the top surface of your skin is left intact while the laser heats only the lower layer. Like erbium lasers, they’re versatile and used to treat a variety of concerns, including the following.

YAG是钇铝石榴石晶体 (Y3Al5O12)的缩写，是一种综合性能（光学、力学和热学）优良的激光基质。 其中Nd:YAG激光器（掺钕钇铝石榴石激光器）是迄今使用最广泛的 固体激光器。 因为能够掺进去的 钕 浓度很高，可达1.3×1020/厘米3以上，故单位工作物质 体积能 提供比较高的激光功率。 Nd:YAG激光器与 钕玻璃激光器 一样，都是以Nd3+作为激活离子，只是钕玻璃中Nd3+的 能级宽度 较大。 Nd:YAG激光器的发射波长为1.064微米， 激光线宽 小于1纳米。 YAG激光器一 …

2024年8月28日 · What is YAG laser capsulotomy? YAG laser capsulotomy (also known as posterior capsulotomy) is a quick, simple follow-up procedure that uses a special laser to treat posterior capsule opacification (PCO). Also known as secondary cataracts, PCO is when your vision is getting cloudy again after a previous cataract surgery.

2013年11月4日 · The neodymium:yttrium-aluminum-garnet (Nd:YAG) laser is a solid-state laser with a wavelength of 1064 nm that can disrupt ocular tissues by achieving optical breakdown with a short, high-power pulse. Optical breakdown results in …

2024年11月7日 · Posterior capsulotomy (or YAG laser capsulotomy) is laser surgery you might need sometime after cataract surgery. It helps you see clearly if your vision becomes cloudy again. When you have cataract surgery, your ophthalmologist removes your eye's cloudy lens. They replace it with a clear, artificial intraocular lens (IOL).

铝掺杂YAG晶体 (YAG:Al)：在YAG晶体中掺入少量氧化铝，可以提高其光学性能，使其透射光谱更加宽广，从而可以用于制造激光器、LED等光电子器件。 2. 铽掺杂YAG晶体 (YAG:Tm)：在YAG晶体中掺入少量氧化铽，可以使其在近红外光波段下产生强烈的荧光，因此被广泛应用于激光器、光学放大器、医学图像传感器等领域。 3. 铱掺杂YAG晶体 (YAG:Ir)：在YAG晶体中掺入少量氧化铱，可以使其在蓝色光谱范围内产生强烈的荧光，因此被广泛应用于LED、显示器等领域。 总 …

2024年12月13日 · yag激光器是以钇铝石榴石晶体为基质的一种固体激光器，其化学式为y3al5o15，简称为yag。 在YAG基质中掺入约1%的激活离子Nd3+，形成Nd:YAG。 实际制备时，需将一定比例的Al2O3、Y2O3和NdO3在单

It has been revealed that posterior capsule opacification (PCO) is the most common delayed complication of cataract surgery. On the other hand, Nd:YAG laser capsulotomy is accepted as standard treatment for PCO. Although, Nd:YAG laser capsulotomy is a noninvasive and safe treatment it carries risk of some complications.
