Can I get cataracts TWICE?? Understanding posterior capsular opacity, or "secondary cataracts"
Yes and no, let’s discuss. With cataract surgery, the cloudy, hardened lens is extracted and a new, artificial lens is implanted. After cataract surgery it’s not uncommon to develop a new problem with the same symptoms as cataracts. Often called a “secondary cataract”, posterior capsule opacity (PCO) occurs when scar, or haze develops on the capsular bag (what’s holding your new lens). There is no way to predict who may be affected by PCO, but there are some risk factors that can contribute, including: age at the time of cataract surgery, previous retinal or glaucoma surgery, or a rare eye condition called uveitis. There is no way to prevent PCO but the good news is that treatment is much easier than your initial cataract surgery.
Posterior capsular opacity is treated via an outpatient laser procedure called a YAG Capsulotomy which is done at a slit lamp (similar to having an eye exam). The procedure does not require anesthesia, only some topical numbing drops. A few quick pulses from a laser breaks up the scar tissue and your vision should improve within a day or two. This procedure is also covered by insurance, much like your cataract surgery. More good news, your eye won't develop PCO more than once.
If you develop symptoms after cataract surgery such as cloudy vision, increased glare/halos, or reduced color contrast you should contact your optometrist to be evaluated for PCO.
