Cateract

And my doctor told me it's very common even though every place I looked online says it's not as common as he said it is.

Not sure about how uncommon it is.  Seems younger patients (under 65) have 50% chance of getting PCO vs 25% after that age according to some studies I read.  That is with uncomplicated cataract surgery.  Those stats go up or down if there are other eye issues going on.   

The design features of the lens inserted at the time of the cataract surgery (the shape of the edges, for example) are a major factor in determining the chance of someone getting PCO after surgery. Unfortunately, the type of the edge best suited for lower PCO often has higher complaints about light reflections from the edges during lights from the side at night.

Cataract surgery - the gift that keeps on giving!   

Hoping I don't get PCO - sometimes that causes more glare too.

Yesterday my doctor told me EVERYONE gets it. That scared me for sure.

And I think the lens I got makes it less like to get it, so I have to ask him about that when I see him again next week.

It wasn't my understanding that everyone will eventually get PCO.  Guess it is a question to ask.  Is there a cost to YAG treatment or is it covered by insurance/Medicare 

Im also worried about PCO. I have a square edge abbott traditional monfocal lens implanted in my left eye. I get a crescent shadow sometimes . At first the shadow came out often and it was very annoying. Two months after surgery, I get it less often. It is ok now.

It's covered by Medicare.

I'm happy to hear it's okay now Peter...try not to worry about PCO (like I'm going to try not to worry). I can be fixed pretty easily.

I found this just now:

Treating Posterior Capsule Opacity

Fortunately, a YAG laser can treat posterior capsule opacity safely, effectively and painlessly. This procedure, known as YAG laser capsulotomy, often can be performed in your doctor's office.

YAG laser capsulotomy involves just a few simple steps:

Usually the eye is dilated before the procedure, with dilating eye drops.

A laser removes the hazy posterior capsule from your line of sight without making an incision or "touching" the eye.

Many ophthalmologists recommend anti-inflammatory eye drops following the procedure.

A laser capsulotomy is a relatively simple, in-office procedure that takes only a few minutes. A laser beam is directed at the cloudy capsule behind the intraocular lens (IOL) and the energy from the laser vaporizes the tissue, restoring clear vision.The procedure takes only a few minutes and is entirely painless; nor does discomfort occur post-operatively.

I wonder if there are any natural supplements out there to help prevent PCO

Laser capsulotomy is a relatively simple procedure, but there are as usual, some risks associated with it (which are often minimized in a sales pitch, until one is asked to sign a 2-page sheet to acknowledge that you understand these).

Yes. I would not stop the prospect of getting a PCO from having a cataract surgery, but will definitely prefer a lens which minimizes the chances of that.

Also, the potential benefit of getting rid of the PCO has to be weighed against the potential risk. I have had a PCO in my left eye for about 17 years with only a small visual impact and have seen no pressing need to get rid of it.

Is the Symfony lens design considered low incidence for PCO?

Yes. Symfony is made of acrylic and also has square edges, which correlate to lower incidence of PCO.
