Yag laser capsulotomy
A Yag capsulotomy is a special laser treatment used to improve your vision after cataract surgery.
It is a simple, commonly performed procedure which is very safe. During your cataract operation, the natural lens inside your eye that had become cloudy was removed. A new plastic lens was put inside the lens membrane (called the bag or capsule) in your eye.
In a small number of patients, the capsule thickens after surgery and becomes cloudy. This interferes with the light reaching the back of the eye. When this happens, your sight becomes misty, and you may get glare in bright light or from lights at night-time.
Yag laser capsulotomy is the only way to treat this.
In a Yag laser capsulotomy the ophthalmologist uses a special lens to apply a laser beam to the capsule. This creates a small hole in the centre of the capsule, which lets light through.
You will have some anaesthetic eye drops to numb the surface of the eye. You will then sit at a machine – similar to the one used to examine your eyes when you routinely visit the eye clinic – which has a special laser attached.
The doctor will put a special mirrored lens on your eye before applying the laser beam. This lens allows the doctor to view the membrane clearly so he or she can apply the laser and make a small hole in it to clear the vision.
