Negative Dysphotopsia with Crystalens HD

I had IOL HD500 implant on 24th of March of my left eye. It appeared to be successful, but no I see a very disturbing arch on the left side (dark shadow towards the ear). I contacted my Dr. , he took notes of my complaints, but did not find anything unusual. I contacted Bausch & Lomb. According to them they have never heard about this phenomenon. Controversy to other reports, the dark arch disappears when the pupil is diluted.

I get my right eye don e tomorrow (same lens with same specification). I am now afraid that the same may occure with my right eye.

What are my options?

I have the same effect also with my new crystalens HD.  If I move my hand back beyond the edge of it I get a brief area where I get a double image of my hand.  I decided I am seeing the edge of the lens.  As for the flickering, see my above question about the 'wiggles'.  I think your lens is moving while trying to accommodate, at least I think that is what is going on with me.  If you look fixedly at one thing does the flickering stop?

I also had crystalenes hd implanted about the same time. Near was perfect but have not been able to see beyond 5' without double or blurred vision. Dr wanted to do yag. I was scheduled then declined . It seems that during surgery every effort is taken to preserve the integrity of the chamber, it did not make sense to the put a hole in it if lens exchange was being considered. Anyways I have developed especially at night this same type of shadow almost like a mini blinder along with a flickering of sorts. It also is to the outside area towards ear. I still cannot tolerate sun or florescent lighting. I am now considering a aspheric lens Technis. Also has anyone had discomfort do to the plates of the crystalen lens?

RLI
I just got back from surgery today (right eye same crystalens HD500 same optic). Did not have the chance to speak to surgeon about the RLI, but I will ask him tomorrow, when he inspects the eye.
As I had very good vision (20/16) and excellent far vision before the cataract started, I am a bit wondering whether this has really developed during the 5 years since the cataract onset. I understand it is the deformation of the cornea. Could this develop from pressure of the eyelids? I have some overhang (inherited).

Negative dysphotopsia
The dark arch definitely disappeared altogether when it was dilated.

I decided to get the same lens in today even with the risk that it appears there as well on the following rational: it does not interfere in night driving condition and I am happy with the overall depth of vision (not need any glasses except very small print in dim light).

John C Hagan suggested to wait and if I can not tolerate it, to implant a monofocal aspheric lens. However, although less complication, better far sight, butI understand it would reduce my range of depth significantly. Hence, I will see what happens. It will probably take a week or so to find out (until the dilation effect is subsided).

LRI stands for "Limbal Relaxing Incisions" which are small cuts around the edge of your iris, used to correct astigmatism. Some doctors do them without really discussing them with patients. It would be worth asking your doctor if you got them, just so you would know one way or the other.

My shadow is really just a thin sliver, so it sounds like yours is much larger. I notice mine more in bright light, because there is more contrast between the bright background and the dark shadow. I have no idea if it is also related to dilation or not.

Hopefully yours will shrink or disappear over time.
