Jälkikatarakta

Jälkikatarakta, also known as posterior capsular opacification (PCO), is a common complication that can occur after cataract surgery. It develops when the thin membrane, known as the posterior capsule, which holds the artificial intraocular lens (IOL) in place, becomes cloudy. This clouding can occur weeks, months, or even years after the initial surgery.

The symptoms of Jälkikatarakta are similar to those of a natural cataract, including blurred or hazy vision, difficulty seeing at night, glare or halos around lights, and a decrease in color perception. These symptoms can affect one or both eyes, depending on the individual. The exact cause of Jälkikatarakta is not fully understood, but it is believed to be a natural healing response of the eye after surgery. Cells from the remaining lens tissue can grow on the posterior capsule, leading to opacification.

Fortunately, Jälkikatarakta is treatable. The standard treatment is a quick and painless procedure called a YAG laser capsulotomy. In this procedure, a laser is used to create a small opening in the cloudy posterior capsule, allowing light to pass through clearly again. Vision typically improves immediately or within a few days after the treatment. The YAG laser capsulotomy is generally considered safe and effective, with a low risk of complications. Regular eye check-ups after cataract surgery are important to monitor for any signs of Jälkikatarakta or other potential issues.
