Cataract surgery is a frequently performed operation during which an affected natural lens is replaced by an intraocular implant (IOL).
What is an after-cataract surgery opacity?
Whenever possible, the IOL is centered within the capsule that surrounded the natural lens before it was removed. If the IOL is in the capsule it is held in place just like the cataract was in place before the cataract surgery. Blurry vision can sometimes develop if this capsule becomes or cloudy. This blurred vision can happen weeks, months or years after cataract surgery.
What a posterior capsulotomy and how is performed?
Capsular opacification needs to be addressed in order to improve vision. The most common treatment for posterior capsulotomy is with a YAG laser.
YAG laser capsulotomy is usually is an in-office laser treatment. After administering anesthetic eye drops a special YAG wavelength laser is focused on the capsule. The ophthalmic surgeon uses the YAG laser to make a small opening in the capsule.
Patients may need to use eye-drops for a few days. In most cases vision returns after a few hours.
