PS: Jan 2018, I also had some scan using Nidek OPD Scan II for whatever it is worth. But I notice that on that particular diagnostic printout there is a glaring difference in the refraction showing between my right and left eye under a panel titled ODP.
My right eye shows :
Sph -5.00 Cyl +1.25 Axis 043 VD 13.75
My left reads:
Sph -11.25 Cyl +2.50 Axis 100 VD 13.75
Not sure why the difference in Sph is so much different from the other refractions.
If you LE has a clinical significant cataract and your RE doesn't then you are going to have a monster problem using the two eyes together unless both are operated on or if the RE no have surgery and they don't work together as is likely your Re would need LASIK or SMILE procedure to balance the two eyes. The last -11.25 you posted is either an error or a huge amount of pseudo(false) myopia due to the cataract. There is nothing in your readings that would preclude a toric IOL in the LE but again, they are not going to work together post op.
Just to be clear, are you saying I will have a monster problem based on the -11.25, or is there some other factor that poses the concern even if the -11.25 were an error or psuedo myopia?
It occurred to me why you say it will be a problem. I had for some reason thought of the corrected left eye, as being no longer a part of the equation in terms of diopters difference with the right. Not sure why I overlooked this.
But I guess if I understand you correctly, if my left eye requires no glasses or contacts correction after surgery (IOL) to provide the intermediate mini-monvision vision I may target, then it will be at zero diopters of correction compared with my right eye, which may need -5.50 diopters of glasses correction to see 20/20. But I take it your saying my right eye wouldn't tolerate more than -1.5 diopters of glasses correction once the left has the IOL?
I have a cataract in the right eye as well, but it is not as far along and doesn't seem to be problematic for me (perhaps that is in comparison to the left eye). I'm going back to see my first doctor Thursday to discuss the lens I want to use and I'll clarify with him then about the right eye. Originally the impression he gave me was the right eye was in early stages. I've not experienced the same rate of deterioration in my right eye vision as with my left, and I didn't think it was going to factor into things right now. But that was before I knew about this issue with 1.50 diopters difference in eye refractions.
I have another appointment with a third doctor next week (he uses the femtosecond laser I think).
I ended up canceling the appointment with the femosecond laser doc, because using the first doc moves the process along and after speaking with him again, I have enough confidence in him.
Anyway, the Dr I'm using has chosen a 15.5 diopter Alcon Toric IOL with a target of -1.50 (I may have that wrong with the + or - ). I told him I preferred a target focus of 21-24 inches. I haven't talked with him since he ran the algorithms, but will be in touch.
When you target a range out 21-24 inches, how many inches usable depth of focus can you expect? If he managed to nail somewhere in that range, and I got a 6 inch depth of focus for instance, that would work fine. Not sure what is reasonable to expect.
Actually, I guess when you say " -1.50 would generally give good computer vision and in good light probably good reading vision except for very small print. " that does indicate that a depth of focus of 20 to 32 inches is reasonable. I always forget that when most people say "reading vision" they are generally talking about a much closer range than I think of. For a book, I suppose I might occasionally lean over a book with head in my hands, elbows on the desk , which might put me 15" away, but usually I'm around 18" away and could just as easily go 20. Computer is more important to me.
