YAG Laser for Posterior Capsule Opacification

Posterior Capsule Opacification occurs several months to years after cataract surgery and lens implantation.  The posterior capsule holds the lens implant is the correct position so that you are able to see and focus after cataract surgery.   During the healing period, your cells on the capsule begin to grow over the capsule and with time, become thickened and block your vision causing glare and blurring of vision.

Treatment of Posterior Capsule Opacification (PCO) is quick and painless.  YAG laser is directed at the centre of the posterior capsule to dissolve the membrane and create an opening to clear the membrane blocking your vision.  After the treatment, you may be given some eyedrops to apply for 4-7 days.


The vision should improve 3-4 days after the YAG laser.  Very rarely, you may need a 2nd YAG laser if the membrane grows back again.
