hi my wife age 39 recently had catarac surgery on her left eye.a new tri focal lense was installed. since the surgery , almost four weeks ago her eye site has remained worse than before the surgery. she has a black shadow in her vision and her eye quivers . her vision is as if there is a vail in her vision . she has noticed that in bright outdoor sunlite she can see much more clearly and even read very well. she has told her surgeon this and he jumps all over the place with no statistics or any real oppinion. he has left her with no answers. my questions there any chance of some recovery , i have heard sometimes it can take months........could the veil affect be a film caused bye the surgery and be repaired with laser surgery...........and could this be an infection that may be un detected. pllease let me know any and all information you can...yours truely mike jean
Doctor DanB : Hello and thanks for your question. Are you available to chat?
Doctor DanB : Assuming there is no problem with retina, I suspect very much that this  is from a change and decrease in contrast sensitivity compared to what the natural lens provided. One of the biggest problems with these new premium intraocular lenses is that in order to achieve useful vision at several different focal planes, the contrast sensitivity that the premium artificial lens provides is less than what the natural lens provides. This can make it seem like there is a veil over the vision and also why the vision improves in bright lighting environments. 
Doctor DanB : While many people are able to adjust to this over time, some people ultimately never get used to it. The time for adjustment usually is anywhere from a couple of weeks to one year at most. However, people that already have eye diseases that limit contrast sensitivity, such as macular degeneration, glaucoma, or dry eye, should not have these lenses implanted and as such are bad candidates for the lenses and usually do not have a good outcomes with them.
Doctor DanB : Does this make sense?

Customer: Hi again the other questions. Are will glasses or contacts fix her vision problem
Doctor DanB : It is possible that glasses can help her brain overcome this problem and that would be the first thing I might try; but it's possible that they may not; unfortunately, everyone's brain responds differently to these things.

Youre welcome. Certainly another option you have is to have this lens explained and a standard, monofocal im
