Posterior Capsule Opacification
Posterior Capsule Opacification
The remaining portion of the capsule becomes clouded in some post cataract surgery patients. When this occurs, patients experience symptoms similar to those from the original cataract. That’s why posterior capsule opacification is sometimes known as secondary cataract.
Signs and Symptoms
- Gradual decrease of vision
- Blurred vision
- Glare from lights and sun
Detection and Diagnosis
Your Optometrist can diagnose posterior capsule opacification during a routine eye exam using a slit lamp microscope, though sometimes the pupils need to be dilated to fully assess the condition.
Treatment
A simple procedure called a YAG posterior capsulotomy is performed to restore vision lost from the clouded capsule. The YAG is a type of “cold” laser used to create a small opening in the centre of the capsule, allowing a clear area for light to enter the eye.
The procedure takes a few minutes, and usually a small local anaesthetic is used to make things more comfortable. Like all surgical procedures, there is a very small risk involved in lasering the capsule.
After the dilating drops wear off, most patients notice an immediate improvement in vision. The improvement each person experiences is dependent on the extent of the capsular clouding and the overall eye health.
