Thanks @bobbyo

It is good that your second operation is OK now, hope the first eye is getting better.

I'm 46 years old , My IOL is for far distance also, and the IOL is Alcon AcrySof model SA60AT which is power 12D, length 13.00 mm, optic 6.00 mm and square-edged,

I have some questions may be you went through them during your search for solution:
- Does any doctor say that you really have positive dysphotopsia (PD) , anyone can physical examine that ? as I went to 3 doctors and all of them said they can't see anything and everything seems OK.
- My symptoms mainly in the room light (strong room light), I feel as someone use reflective mirror and reflect the light to my eye , by searching and reading I have concluded this is PD, but still no doctor confirm that this is PD, so I'm thinking is there any issue can cause this symptoms aside of the PD ?
- If it is PD, does anyone suggest to you to change the IOL size in the second eye, as per my reading this problem may come because the pupil size is large , so why you did not use IOL larger than 6mm in the second eye ?
- PD are very annoying , but do you have any info if it is harmful to they eye , retina and cornea , I mean if I managed to stay with it and don't take any action , does it hurt my eye in the future or it does not have any bad effect ?

I'm sorry for the many questions, but I really need to find out what is the problem before going for the second operation especially that I may not find all the IOL options in my country.

Thanks again for your reply and have a nice day and good luck

You ask a lot of great questions.

Below, in order of your qs:
- It’s true, they seem to avoid the term. Although, when I brought it up they said that only a small percentage of patients (like 2%??) get long term PD. I tell them, “well, I got it 100% of the time.” I think they like the overall safety and general success of their “go to” lenses. They hang on their contention that there’s no way to predict who will get PD.
- I don’t know what other condition might make someone prone to PD.
- I tried Vivity to shrink the pupil and assure that the IOL was bigger than pupil. But, PD remained unchanged.
- I don’t know of PD being harmful to the health of eye.

As said, I’d still hope that yours, being just 2 months post surgery, will resolve through “scar tissue” growth, neuroadaptation or whatever.

Good luck to you!
