The back (posterior) part of the capsule which is just behind the artificial lens can become cloudy (opacify) in up to 10-20% of eyes that have undergone routine uncomplicated cataract surgery. Posterior capsule opacification (PCO) is the most common complication of cataract surgery. PCO can cause blurry vision and other symptoms in some people. The early changes first appear as fine granules in the posterior subcapsular area of the lens. Potential complications of untreated CBS include: glaucoma, posterior capsule opacification, and posterior synechiae [4]. The YAG Laser Procedure The capsulotomy requires the use of a Nd:YAG (Neodyium - doped yttrium, aluminum, and garnet) laser, which is generally just called a YAG. In any case, this is a clouding that may resemble the symptoms that a person had before surgery, and . Cataract symptoms depend on the location and severity of the opacity. Advances in surgical techniques, intraocular lens (IOL) materials, and designs have reduced the PCO rate; however, it remains a significant problem resulting in suboptimal outcome of cataract surgery. Posterior capsular opacification (PCO) occurs when a cloudy layer of scar tissue forms behind your lens implant. The posterior capsule is the clear layer of tissue that supports the intraocular lens, which is implanted into the eye at the time of cataract surgery.
