Am I understanding mini-monovision correctly?

Thanks, Dr. Hagan, for the recently updated "Before You Consider Cataract Surgery" article
My plan (being presently high myopia) is to have as good near and intermediate vision possible with a standard monofocal IOL and use progressives (as I do now) for distance.  If I understand correctly, in order to get better intermediate as well as near, I'd go for a slight difference (mini monovision) in refractive error between the two eyes such as -1.75 and -3.00.  If I aim only for near being good, I'd go for the two eyes being more the same level such as both eyes at -1.75 or one at -1.75 and one at -2.00.  "Near" would be the latter and mini monovision would be the former, if I understand correctly.   (This doesn't address my eye situation which is more complicated which I'll be discussing with the doctor).  It's the difference between aiming for being 'slightly nearsighted' (refractive error more equal between eyes) and 'slightly nearsighted but with added better intermediate' which is the mini -monovision with more difference between the eyes' refractive errors.
On another forum I also noticed the term 'micro monovision' which I assume means even less of a difference.
Thank you

No really. If you wanted both to be good at near  then you would target -2.50 to -3.00 in both.    Mini-monofocal near bias would be  -2.50 to -3.00 in your reading eye. and -1.25 in your intermediate eye.  Do discuss this with your surgeon as each person is somewhat different in their needs, and their expectations.

Thank you, Dr. Hagan.  Yes, I'll go over it all in the visit.  It does help to do some extra reading here first.  I have one additional question from what you just wrote - when you say 'vision good at near' does that necessarily mean 'without glasses'?  I really do not mind wearing glasses all the time (progressives) - I've been wearing them for about 15 or 20 years already.  But I just wonder if when people say 'good' vision do they mean 'without needing glasses'?  Thanks again.

Yes assuming the eye is healthy and your post op near refraction is say -2.50 if you have astigmatism it degrades the image without glasses.
