What is the difference between posterior polar and posterior sub capsular cataract?

Posterior polar has risk of capsule damage during the surgery due to adhesion of opacity to the capsule. 

Is this the same as posterior sub capsular cataract?

I thought posterior polar cataract is basically a posterior subcapsular cataract but have the cataract concentrated in the visual axis instead of surrounding it.

Posterior polar cataract has high risk of capsular rupture during surgery.

My doctor said I have posterior polar cataract. I had my surgery done in my left eye and I was told by my doctor in immediately after the surgery that my capsule was intact . Have you done your surgery yet ?

Hi Peter

No surgery.  I am going to delay as much as possible.  What's the option if capsule ruptures?  Do you lose vision?

Should you do this early so less opacity is attached to the capsule?

Were you told you have posterior sub capsular cataract? or polar?  or both?  Did you have laser surgery?

 

Hi Soks,

The chance of posterior capsule rupture is all based on luck and surgeon handskill . It may be rupture before the surgery (if you see some little strips in your vision) or during the surgery (if the surgeon is not stable with his hands during suction or suction pressure too high or if you move your body during that important few seconds). If it does rupture, the doctor will need to do a small additional procedure called vitretomy. You will not loss vision at all. It is just an additional procedure to hold the lens in place.

If you have capsule rupture and vitreous loss, then the future chance of retinal detachment will be higher.

I had polar cataract, I was lucky, my capsule did not break during the surgery. I had the same worries like what you are having now.

How's your vision now ?

Are u seeing blurr when you watch tv ? Under sunlight ? Are u still able to drive ?

My right eye is seeing just blurr of everything at 10 feet away now. Cant even watch tv if using only my right eye.

I have scheduled my doctor visit on sept 28 to assess the vision remaining and determine if I should go with surgery.

And I did not have laser surgery because I think some website mentioned the risk of posterior cap rupture is not lower and you need to move from one bed to another to finish the surgery if you do laser. That introduce more risk to me I think.

I can watch tv just fine. Road signs r a problem with one eye. 

I have 2 separate links. One says polar and sub capsular are same. Other says they are different. 

I think you are still in your early stage of cataract. When you cant watch tv or you cant drive without someone sitting next to you giving you a description of the objects in front. Then it is the time to get it fixed.

Did both your eyes become blurry at the same time?

Are you in a big city?

How good is your near/intermediate vision on the operated eye?

My left eye went blurry first then 3 months later my right eye too

For my operated eye: Far vision excellent, intermediate vision for conversation ok, any fine prints 30 inches or closer cant read without glasses .

Yes, in a big city.

So I confirmed with ophthalmologist that the two types are different.  She also mentioned some type of test to determine if symphony are good for you or not.

That's great ! So what's the difference between psc and posterior polar ?

She did not give that detail.  Just said that they are distinct from polar.  I am seeing another surgeon and will ask him as well.

Were you able to see the cataract in the mirror?
