Surgery tomorrow - 2D spread

[jeffw_00]

So, after a lot of discussions, experiments (where I walked around for a while with differing prescriptions on my eyes) etc.  We've decided to put a 3.75D lens in my right eye (currently -5.25).  This will put it 2D away from my left eye (currently -5.75).  Not a perfect solution, but my criteria was this - I work at computers all day, and like my vision really sharp (if it's off by 0.25D, I can tell).  So I expect to wear glasses for the rest of my life, which I don't mind, because all of the stuff I've seen here about Crystallens, monovision, etc, seem to suggest that while pretty good, it's not the type of sharp vision one can get with glasses. (especially as I have 0.75 - 1.0 astigmatism in both eyes - too little to correct with Toric) (also, I really didn't want to do anything with my left eye right now, it's sharp, no trace of cataracts, etc, and I'm only 52).  

His concern was this - he said that with more than 2D spread, I could have some noticeable effects (momentary double vision, ghosting, etc), even with glasses.  I had thought from what I've read here he would have gone for more like 2.5D, but I'm not sure it really makes a difference.  Bottom line, my unaided vision will (I think) be better, reading without glasses may be easier, and my corrected vision will be back to the sharpness I was used to before I got the cataract.

He said that if i ever needed cataract surgery in my other eye, he would correct for distance and recommend "refractive surgery" in my right eye.

Anyway, that's what I think will happen & why,  your comments are quite welcome (I mean, that's why 'm posting 8-}

happy holidays

Dr Hagan - does "no comments" mean "makes sense to me" ? 8-}

Jodie - Cataract isn't related to anything prior.  It's likely I'll eventually get one in the other eye, but it could be a year, or a decade...

He's putting an aspheric IOL in the right eye such that my 'natural' vision will require a -3.75D eyeglass lens to correct properly for distance.  (2 less than what's required in my other eye)

Your post does not make total sense to me.  There is no such thing as a -3.75D IOL.  I suspect that your surgeon will be using an IOL which is predicted to give you a refractive error of -3.75.  IOL power predictions are not an exact science, but it is very likely that you'll be end up within .5 diopters of your target (i.e., between -3.25 and -4.25).

Is your cataract related to a trauma or to retinal surgery?  If not, you'll probably need cataract surgery on your other eye in the not-so-distant future.

Best of luck tomorrow.  I hope your outcome exceeds your expections.
