Laser posterior capsulotomy is performed with Nd:YAG laser, which uses a wavelength to disrupt the opacification on the posterior lens capsule. This lens implant sits inside a natural bag (capsule) inside the eye. It more frequently affects younger patients. In this procedure, a laser is used to remove the hazy capsule situated behind the IOL implant. Posterior capsule opacification (PCO) One of the most common cataract surgery complications is a posterior capsule opacification. What is posterior capsule opacification? Posterior capsule opacification (PCO) is one of the most common problems following cataract surgery. PCO is treated with Nd:YAG capsulotomy, a quick outpatient procedure that uses a laser to open a central hole in the posterior capsular bag. I'm a 41 year old female, and I'm a software engineer. The risk of PCR is higher during cataract surgery for PPC partially as a result of the tight adherence of the posterior polar opacity and the reduced integrity of the thin PC [7] [8] [9]. In this approach, the emulsified material is aspirated out of the eye through the handpiece in a manner similar to phacoemulsification. The laser can also be used to remove the laminin layer of the posterior capsule, which can prevent posterior capsule opacification. Posterior capsule opacification (PCO) is the most common postoperative complication with the prevalence about 50% in the 5 years after cataract surgery [].However, if PCO occurs early after surgery it dramatically reduces patient satisfaction because of the increase of light scattering and the reduction of visual performance [2, 3].Neodymium-yttrium aluminum garnet (Nd:YAG) capsulotomy is .

Posterior capsular opacification (PCO) is the most frequent complication of cataract surgery. The basis of the condition is a pronounced wound-healing response from residual lens epithelial cells, which colonize the lens posterior capsule, deform the matrix, and form cell aggregates. PCO can cause significant visual symptoms and is effectively treated with laser capsulotomy. The posterior capsule is usually free of lens epithelial cells. Fibrotic posterior capsular opacification (PCO), a major complication of cataract surgery, is driven by transforming growth factor-β (TGF-β). Posterior capsular opacification (PCO) occurs when a cloudy layer of scar tissue forms behind your lens implant. Overt time, this capsule can become cloudy, leading to blurred vision and PCO.

Posterior Capsular Opacification (PCO) Posterior capsular opacification, referred to as 'secondary cataract' or 'after cataract', develops over the clear posterior capsule a few months to a few years after an uneventful cataract surgery (Figure (Figure2A, 2A, ,2B, 2B, ,2C). A posterior subcapsular cataract is a form of opacity that affects the back side of the eye's lens. A YAG laser capsulotomy is one of the most rewarding procedures that optometrists can be a part of. The majority of patients had involvement of the peripheral part of the posterior capsule (76.3%) as compared to the central area (23.7%). This condition affects 1 out of 4 patients within 5 years of undergoing cataract surgery.

Little is known about the long-term incidence of posterior capsule opacification (PCO) after cataract surgery in patients with uveitis. During cataract surgery, it is impossible to remove 100% of the lens epithelial cells (LECs), and those that remain can cause postoperative capsular contraction and posterior capsular opacification (PCO; Figure). PCO can cause significant visual symptoms and is effectively treated with laser capsulotomy. The vision problems caused by PCO can make it seem as though your cataract has returned, but it can be easily treated with a quick, painless, outpatient laser procedure to make vision clear again. This might trigger you to have blurry or hazy imaginative and prescient, or to see lots of glare from lights.

Incidence rates used to be as high as 50%; but with improvements in surgical technique, IOL designs and IOL materials, the incidence has decreased to about 14% to 18%.1. PCO is a physiological change (thickening, opacification and clouding) of the capsular bag expected after cataract surgery, because the lens epithelial cells (LECs) undergo hyperplasia and cellular migration. Personalised recommendations.

I had cataract surgery for my left eye on Nov.6, and the right eye a week later. Precisely, the posterior capsular opacification occurs as a consequence of the fibrosis and opacification of the posterior capsule due to the migration of the lens epithelial cells that remain in the capsular bag after the intervention. PCO is fairly common after cataract surgery, occurring in about 20% of patients. Oftentimes, PCO is noticeable to the examining doctor within days of the surgery, but it also could be delayed months or years. Both conditions represent the anatomic correlate of a secondary cataract (SC).

The incidence of posterior capsular opacification varies in different studies, and is cited as occurring in 30% to 50 . The energy emitted from the laser forms a hole in the lens capsule, removing a central area of the opacification. Some intraocular lenses (the lens that is put in the eye during cataract surgery) result in less PCO than other lenses. Posterior capsule opacification (PCO) is a complication that can occur some time after cataract surgery. It causes a gradual deterioration of visual acuity, which would otherwise improve after a successful procedure. To treat this posterior capsule opacification, doctors use a type of laser called a Yag laser to make a hole in the back of the capsule to clear away the cloudiness so that light may pass freely to the back of the eye.
