Negative Dysphotopsia with Crystalens HD

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?

Hi,

I had a Crystalens HD implanted 7/7/09.  I have what I refer to as a "hair" and sometimes there is flickering or fluttering with the hair.  I don't know my dilated pupil size, but undilated I'm 4 mm.

I have fabulous vision except for this.  So far, it is too much to ignore, yet I am generally thrilled with my results.

I've been sort of logging my experience in a post called Crystalens Result.  It's a bit wordy, sorry.  Was overwhelmed after being blind in the eye that had the surgery.

I too am contomplating Crystalens HD.  This is a question with those of you with this iol and have problems with edge glare or shadows.  How large are your pupils when diolated?

I had my stitches removed 4 weeks after the implantation (18th of May second eye). This did not improve the disphotopsia phenomenon at all (only dilation makes it disappear for a while). My Dr indicated (as yours did) it could be the edge of the section in the centre of the lens. I don’t believe it, it is just so pronounced. I also have the impression that the whole picture I see is smaller than it used to be (like looking through strong glasses when you are very shortsighted).

I can actually see the lenses contracting when I focus. When I focus very close with white background I can see almost the whole circle of the lens, but very little beyond the edge. I believe the lenses are simply too small (it may be that the anatomy of some peoples eyes make it more pronounced).

I have sent a report to the Rep of Bausch & Lomb, but have no response so far.

It would be good to know how many people have this phenomenon with the Chrystalens. Perhaps Dr. John C Hagan could initiate a survey or something like that?

No I havn't been post-op long enough, the dark ark was so intrusive that was my primary concern. My surgeon rotated my cryslalens 90 degrees and the ark remains but much more transparent. Past the ark is double image (2 hands ect.). Ark is gone when eyes dialated but double image remains only past ark. I can either live with it or replace with different lense. The fact that it is not black has made it easier to ignore.however catching the double image can be very distracting at times.
I think whats happening is my pupil is offset slightly twords my nose. The hd has a center area to improve close vision and I am seeing through the edge of that section. I think. The lense is centered but my pupil is not. Probably natures way of  dealing with my nose.

This is all just a guess on my part. It is what it is and I will have to deal with it.

I had the dark arch on one of my two CL eyes. Today I had my final stitches removed (4+ months post-op!) and the arch seems to be gone, or at least dramatically reduced. Mine only appeared when I flexed my eyes to focus at a far distance, but I'm glad it's gone.

gixxer: Have you tried eye exercises to practice focusing at distance? My distance vision with relaxed eyes is not great, but I can "pull" things into focus, with practice.

I had a Bausch and Lomb Akreos lens put in last week and I'm having the same problem.  I'm especially upset because I discussed this in detail with my doctor because I had so much trouble with my first implant that I wanted this one to be right.  I did a lot of research and we settled on A DIFFERENT lens (NOT the B and L Akreos which was never mentioned).  Last minute in surgery, he put in the B and L for some reason.  He said it was "The same thing".  I use my eyes for a living and am not happy with the negative dysphotopsia (parenthesis effect) at all.  I'd love to hear from someone who had this problem and saw it resolve over time.  If not, I may be requesting a change of lenses during my ten day post op.
