Can a cataract come back?

Because the natural lens is removed during cataract surgery, a cataract cannot come back.  However, in approximately 15% of cases, a “secondary cataract” can develop.  This clouding of the bag (capsule) holding the implant gives the same symptoms as the original cataract.  Secondary cataract can develop anytime post-surgery but most commonly within the first few years. 

Secondary cataract (posterior subcapsular opacification) is quick and easy to treat with laser.  The treatment does not require and operating suite so it is done with little wait time.  Secondary cataract does not return once treated.
