Posterior Capsular Opacification
Posterior Capsular Opacification: This is the occurrence of a membrane that is hazy (capsule) right behind the intraocular lens implant. This disorder is often denoted as “secondary cataract”, although this term is a misnomer since when a cataract is removed it will not develop again.
Ophthalmologists usually prefer, during cataract surgery, to position the “intraocular lens implant” in the identical anatomical place that the lens that was natural – cataract – has within the capsular bag. The lens that is natural of the eye is held within a membrane that is thin and is known as a capsule. When the cataract in an adult is removed, the ophthalmologist makes every effort to uphold the veracity of that capsule, because the lens implant will be placed in it. The part of the capsule that is anterior will be opened in order to take out the cataract but the side that is posterior of the capsule is kept intact in order to offer the lens support and to stop vitreous humor from inflowing to the front or anterior eye chamber. After surgery about 20 percent of individual patients with posterior capsules intact will develop cloudiness of the capsule recognized as “posterior capsule opacity” that results in vision that is blurry. In fact often it can be worse than the haziness was prior to cataract surgery.
But luckily, by means of the YAG laser, the management of “posterior capsule opacity” is effective, safe, and painless and may often be performed as an in-office process. In this process, referred to as “YAG laser capsulotomy”, this hazy posterior capsule is removed from the visual axis or line of sight – using the advantages of this laser. This lets the surgery be completed with no incision or “touching” of the eye. The individual patient needs to be cooperative and those patients who are very uncooperative, such as mentally retarded or children patients – might need sedation for this process or the posterior capsule can during a second surgical operation be opened while the patient is under general anesthesia.
