PCO laser refers to the laser procedure used in Posterior Capsulotomy, also known as YAG laser capsulotomy, which is performed to improve vision after cataract surgery.
Here's a breakdown:
-
Context: After cataract surgery, some people experience a clouding of their vision months or years later. This isn't a recurrence of the cataract itself.
-
The Cause: During cataract surgery, the natural lens of the eye is removed and replaced with an artificial lens (IOL). The IOL is placed within the lens capsule. Over time, this capsule can become cloudy, a condition called Posterior Capsule Opacification (PCO).
-
PCO Laser to the Rescue: The YAG laser (yttrium aluminum garnet laser) is used to create a small opening in the cloudy posterior capsule. This opening allows light to pass through clearly, restoring vision.
-
The Procedure: The procedure is quick, usually painless, and performed in an outpatient setting. Eye drops are used to dilate the pupil. The YAG laser is then focused on the posterior capsule to create the opening.
-
Benefits: Improved vision, reduced glare, and enhanced clarity are the typical outcomes.
-
Synonyms: Common terms for this procedure include:
- YAG laser capsulotomy
- Posterior capsulotomy
- Laser capsulotomy
In summary, PCO laser is the laser used in a posterior capsulotomy procedure to treat clouding of the lens capsule that can occur after cataract surgery, restoring clear vision.
