What is a secondary cataract?

The lens of the eye will be removed during surgery, the natural bag or capsule of the lens remains intact so that the implant can be placed within it.
Months to years after your surgery, this capsule can cloud over and blur your vision. What happens is that the patient reports gradual blurring of vision.
The diagnosis can usually be confirmed by the optometrist (optician), and the patient referred back to the eye surgeon.
This is very easily remedied with a laser procedure, involves clearing a central area of the opaque capsule using a special laser, called a capsulotomy.
This restores vision almost immediately; it is painless, and always done as an outpatient procedure.
