Posterior capsular opacification
Home / Cataract surgery / Posterior capsular opacification
Cataract surgery consists of cutting a small window in the front of the “capsule”, the thin, transparent membrane enveloping the eye’s natural lens, removing the cloudy lens, and replacing it with a synthetic intraocular lens implant. During this process, the surgeon leaves the posterior capsule intact. This is the part of the eye which may become cloudy or opaque months or years after cataract surgery. The condition is called “after-cataract” or “secondary cataract”.
Gradual decrease in visual acuity months or years after the first cataract surgery.
To restore the vision, the surgeon uses an Nd: YAG laser to make an opening in the centre of the posterior capsule (capsulotomy).
Capsulotomy is a simple, painless outpatient procedure. It takes only a matter of minutes, after the pupil has been dilated and anaesthetic eye drops have been placed in the eye. The patient immediately goes home with an eye drop treatment.
