Mini Mono Vision infomration Required for Cataract surgery decision

[ndesai]

Hello Everyone,

I am 46 yr. old, have astigmatism in both eye and have already done cataract
surgery in right eye, Toric IOL set to distance in my right eye and thinking of doing
left eye with mini monovision using Toric IOL, I have a surgery next week
for Toric, Distance, I am thinking of getting mini Mono Vision -1.25 done in my left eye, so based
on my reading in the forum, I have few questions, so I would like some answer
so that I can make informed decision to go with Mini Monovision

1>What I am expecting from Mini Monovision is that I should be able to have better
intermediate/distance vision, which will ALLOW me to read computer, dash board in car
and so on, is this realistic expectation ?

2>I am thinking I should not expect to read from Near distance when it is set for intermediate
in left and distance in right ? I will need to have reader for reading near

3>I spend 10-12 hrs. on computers and using one eye for intermediate for that long
will make my eye tired ? if that is the case, can I use progressive glasses over mini
mono vision to work on computers ? which will allow me to read intermediate without
glasses during temporary activities and for prolonged I can use glasses

4>Will few days is good enough test to check whether your brain will accept mini mono vision  ?

5>When I called Dr. office they told me since I have astigmatism, getting test contact lens to simulate
mini mono vision might not be readily available, it will take some time and it won't
be covered by insurance, what are my options to test my adaptability with mini mono vision ?


5>Is difference between two eye should be -1.25 to get mini monovision,which will
allows you to get intermediate range in one eye(non-dominant) and distance in other
eye(dominant), is this correct ?

5>Are there possible to have Glare/Halo using Toric IOL just due to
using Mini Mini Mono vision ?

6>Are there any downside of using mini mono vision over long term ?

7>If at some point, if brain do not like mini Mono vision, can I use progressive glasses
over mini mono vision for all distance ?

8>Because of mini Monovision, do I loose crisp vision in distance ?

9>I can use progressive glasses over mini mono vision to get crisp vision for all the distances, is this
correct ? if I need crisp vision for certain activities and having mini mono vision would not
prevent me from using progressive glasses for better vision, is this correct ?


I will really appreciate your response in this regard, so that I can make educated decision
for mini mono vision and also can set my expectation accordingly.

Thanks for taking time.

Unfortunately, I had my dominant right eye under corrected for mini monovision and it has taken me a long time to adjust. I wear glasses nearly all the time for crisp vision--whether distance or reading. I wonder if I would have better results if my dominat right eye was corrected for distance my left eye undercorrected. I could have lasik to bring both eyes to 20/20, but then I would need reading glasses all the time even for the light reading mentioned above. I am not sure what I am going to do---any suggestions? Thanks!

By the way, by light reading, i mean like the routine stuff you do throughout the day (both inside and outside) such as writing notes, reading the mail, signing a credit card receipt, looking at your tv's remote control, looking at a restaurant menu, etc etc etc...

With mini monovision you can do all that without readers, with full 20/20 correction in both eyes, you would need to pop on the readers for all those types of things...which is a real pain in the you know what...

Actually, i am not a heavy reader these days...i do most of my reading on the computer screen and those various light reading activities as i outlined above, so it is fairly rare that i actually wear my (light) readers...

But if you like to do a lot of book and magazine reading, you may will find that the light readers will make it more comfortable and less straining...
Still, you won't have to lug around reading glasses every place you go!

Hi! Welcome back and Happy New Year to you too...

Yeah, you do lose some sharpness due to mini-monovision (when using both eyes) when it comes to reading...you will probably find that if you hold the page a bit further back it gets sharper, as opposed to closer where you may get a slight blur...that sounds pretty normal to me...

I find that it works very well and frees me from glasses about 95% of the time...If you have both eyes corrected to 20/20 you would be carrying around readers with you all the time and using them a LOT...with mini-monovision, you avoid that...

I find it (mini monovision) works out well for light reading, but if i was going to do heavy reading (say, reading a book or a couple of magazine articles) i'd want to pop on my light readers for that...i use the weakest ones for reading, which are about +1.25)...you may want to do the same...

Computer i can do for hours with no problem at all...and no readers...

Hello Craig10x,

Happy New Year!

I am been using contact lens in my left eye with -1.5, it seems -1.5 is working out better than -1.25. So with mini mono vision is working out for me.

However, what I have noticed that when I am using -1.5, when looking through both eyes, Yes, I can read, but not as clear/sharp as I can see with only left eye(one with contact lens) open, is this normal ? are you suppose to see image clear/sharp with one eye or both eye to the same degree ? or do we loose some sharpness due to mini mono vision ?

your response will be appericiated.

No problem, you are quite welcome...i can understand what you are going through since i have already been through it...

Well, i just meant that it isn't possible to get everything perfect...if you maximize reading (by going to higher diopters) then you sacrifice too much from distance and midrange...so there is ALWAYS going to be some "trade-off"...

And since you have somewhat of a cataract already in the eye you are trying the contact with, it could be taking away a bit from what it will REALLY be like after the lens is replaced and the cataract is completely gone...In other words: it may be even BETTER then what you see right now...

For most people, distance and midrange are the priority, so that is why mini monovision is usually the best compromise....it still allows reading of mail, menus in restaurant, looking at your shopping list, reading labels on grocery items, etc, pretty well...I get tired if i tried to do extended reading also...so, when i do, i put on the weak "readers" and that solves the problem!

I wouldn't wait, if i were you....my other eye didn't have a fully developed cataract yet, either, but in fact i had my done just 4 days later...I wanted to get my eyes "in synch" as it were...and YES you do NOT have to wait until the cataract is fully developed to have the iol replacement for it...

Better to have your eyes "match" with the same type of lens that you have now, then wait for possible future technology developments...Things might get thrown "off balance" if you mix as you are suggesting...that would be my advice, based on my own personal experience...It's best to try to avoid potential problems...
