Dr. Sam Masket presented his theory of dysphotopsia. You can probably Google it. It was presented at ASCRS in the Spring in Boston.
Yes, square edge IOL do have more dysphotopsia. It seems to occur more with arcylic than silicone IOLs. I believe that Tecnis has a square posterior edge (to decrease PC haze) and a rounded anterior edge to decrease dysphotopsia.
Thanks a lot, I will do some research on this.
How about the AcrySof IOL ? Are there a lot of complaints about dysphotopsia ?
I think dysphotopsia is quite an important factor to me.
If there is PC haze, we can do a YAG to fix it but this is difficult to fix dysphotopsia except ignoring it.
I am seriously bothered by the very blur side image for 10 months and I found this is quite difficult to ignore it. I hope this is just because the effect of cataract and I really want to minimize the risk of running into the problem of dysphotopsia.
