This cataract surgery yag is known as YAG laser capsulotomy as an article writing material on how to treat posterior capsule opacity safely, effectively, and without pain.
Cataract Surgery Yag
Cataract surgery is one of the most common and most successful surgical procedures performed today. According to the American Society of Cataract and Refractive Surgery (ASCRS), 3 million Americans undergo cataract surgery each year, with an overall success rate of 98 percent or higher. Also, a study of more than 200,000 Medicare recipients undergoing cataract surgery between 1994 and 2006 found that 99.5 percent of patients had no complications after severe surgery and the risk of severe complications had decreased with advances in surgical equipment and techniques.
When complications of cataract surgery do occur, most are small and can be successfully treated medically or with additional surgery. One of the most common complications of cataract surgery is the posterior capsule opacity (also called the posterior capsule opacity or PCO). Although some people refer to PCO as a “secondary cataract,” it is not really a cataract. Once the cataract is removed, it does not return.
During cataract surgery, your surgeon will remove a cloudy natural lens from your eyes (cataracts) and replace it with an intraocular lens (IOL). Most of the thin membranes that surround a natural lens (called lens capsule) are left intact during operation and IOL is usually planted in them. When cataracts are removed, your surgeon will try to maintain the integrity of the lens capsule, and usually your vision after cataract surgery should be very clear. However, in about 20 percent of patients, the posterior part of the capsule becomes blurred for some time during recovery of cataract surgery or even months later, can cause PCO. Posterior capsule opacity occurs because the lens epithelial cells remaining after cataract surgery have grown in the capsule. In some cases, if the condition goes significantly, your vision may be worse than before the cataract surgery.

Fortunately, YAG lasers can treat posterior capsule opacity safely, effectively, and painlessly. This procedure is known as YAG laser capsulotomy, and can be done in your doctor’s office. YAG laser capsulotomy involves only a few simple steps. Usually the eyes are dilated before the procedure, with enlarged eyedrops. The laser removes the misty posterior capsule from your vision line without making an incision or “touching” the eye. Many eye doctors recommend anti-inflammatory eyedrops after the procedure. This procedure only takes a few minutes and is completely painless; also no discomfort after surgery.
YAG laser surgery is performed by removing the posterior zone of the posterior capsule behind the intraocular lens, and this condition cannot be recovered. So only one laser treatment / surgery is needed to remove cataracts caused by the posterior capsule opacity in order not to cause permanent loss of eye sight. YAG laser capsulotomy also poses little additional risk, but overall the procedure is very safe. The most important risk is that the retina can be detached from the inside of the eye.
Other potential cataract surgery complications range from mild inflammation of the eyes to visual impairment. The risk of severe loss of vision is very rare and can occur as a result of infection or bleeding in the eye. Some complications of cataract surgery occur a few moments later. Other potential complications of cataract surgery are mild and may include: Swelling of the cornea or retina, Increased pressure in the eyes (ocular hypertension) and Dull eyelids (ptosis). Minor complications are usually lost with medication and more healing time.
Based on this it can be concluded that a few months or years after cataract is removed, part of the capsule (lens cover that supports artificial lens implants) can become turbid, affecting the clarity of vision. This is called a posterior capsule opacity, or PCO. With a posterior YAG laser capsulotomy, your ophthalmologist makes an opening in the center of a cloudy capsule with a laser to allow the light to pass through the lens properly again. Posterior YAG laser capsulotomy may be performed immediately after cataract surgery, but most ophthalmologists think it is wise to wait 30 to 60 days for the intraocular lens implant to fully sit in place and to avoid additional inflammation (swelling) immediately after surgery. I suggest you discuss this more fully with your eye doctor.
