Kapselopaciteit

Kapselopaciteit, also known as capsular opacity or aftercataract, is a common complication following cataract surgery. It occurs when the posterior capsule of the natural lens, which is left in place to hold the intraocular lens (IOL), becomes cloudy or opaque. This clouding can happen months or even years after the initial surgery.

The primary symptom of kapselopaciteit is a gradual blurring or dimming of vision, similar to the symptoms of the original cataract. Patients may also experience glare, halos around lights, or a decreased ability to see in low light conditions. The severity of these symptoms depends on the extent of the opacity.

The exact cause of kapselopaciteit is not fully understood, but it is believed to be a biological response of the remaining lens epithelial cells. These cells can proliferate and migrate onto the posterior capsule, leading to opacification. Certain factors may increase the risk, including age, the type of IOL used, and inflammatory responses.

Diagnosis is typically made by an eye care professional during a routine eye examination. They can observe the cloudiness of the posterior capsule using specialized equipment.

Fortunately, kapselopaciteit is treatable. The standard treatment is a quick and painless procedure called a capsulotomy, often referred to as a YAG laser capsulotomy. In this procedure, a laser is used to create a small opening in the opaque capsule, restoring clear vision. Recovery from a YAG laser capsulotomy is usually rapid, with most patients experiencing significant visual improvement within a day.
