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.

Hello Craig10x,

Thanks for replying based on my reply to the Dr

Since Dr was suggesting crystalens, I thought it might be a good idea to matche with Toric to get more reading/intermediate range without sacrifying sharpness using crystalens in my left eye  ?

I know Toric crystalens is not available, so was wandering if that is something in the future developement, so may be I can wait as I do not have much cataract developed in my left eye, provided this match works out good

I did not understand your comment - Also, keep in mind that even though the cataract isn't fully developed in your non dominate eye as of yet, it could be detracting from what you are seeing with your "experiment contact lens"....

What you meant by that ? Can you please explain. Using contact lens for mini mono vision, I am able to works on computer and can also read menus and so on, which I can't do without contact lens. But I am not able to read iphone mail msg for longer than 5 minute, but I can do that, when I read some documents.

I am happy with my current intermediate/reading range but if possible would love to get little shapness and better reading range, and so I thought of using Toric crystalens when available ?

Also even if my cataract is not fully developed (very little), I can still go-with removing it and replace with IOL, isn't that correct ?

Again thanks for your concern and I really appericiate it

-Regards

By the way, i noticed you asked the doctor in your other post about crystalens...i don't believe you can get them in toric...also, it isn't such a great idea to mix lenses anyway (one monofocal and one multifocal) and if you look through the theads you will see many who have had problems with multifocals and also the crystalens as well and ended up having them exchanged for monofocals...

You may not get the results you are seeking with that lens...sounds like you are trying to achieve perfection, which is not possible with this technology...

Also, keep in mind that even though the cataract isn't fully developed in your non dominate eye as of yet, it could be detracting from what you are seeing with your "experiment contact lens"....

Again, the choice really comes down to either having both eyes set to 20/20 and end up wearing readers around your neck (or carrying in your pocket) all the time to see anything that is closer then arm's length or
doing mini-monovision and get very good distance and mid range (which includes computer viewing) and light reading without the readers...

Hi again!  So you are in your experiment phase now (like i did with the glasses) lol...

Well, if you increase to -1.75 it might improve the reading slightly but it will also take a bit away from distance/midrange....

Remember, i started with -2.25 and though i could read close, it wasn't super sharp even then, and i was sacrificing too much in the midrange and distance, i found...

When i went to -1.50 i do see the page sharper to read, but then i have to hold it further back now (several inches) but my distance and mid range (which includes computer) is much better now...

Keep in mind, mini-monovision is slanted toward better distance and midrange and really for reading, it is really for brief reading, like seeing menus in restaurants, groceries on your supermarket shelf, signing credit card slips, reading your mail, you know...LIGHT READING....

It allows you to escape your glasses likfe for 90% of your activities...for extended reading, even I would need to pop on my (weak) readers (i use +1.25 for that)...

Think about it....90% of your activity is done in distance and mid range....Reading is generally the smallest activity of what most people do all day and night...

Personally, i wouldn't recommend going for more then -1.50 diopters for your non-dominant eye...

Also, it takes some time to adjust to monovision (even mini) but don't expect to be able to read a novel without any reading glasses...ain't going to happen!

Hello Craig10x,

I have few questions, during trial period of mini mono vision with my contact lens in my left eye set with -1.5D since past 5 days

1>I am not getting clear reading vision, it seems fuzzy after reading for more than 5 minutes, If I use readers, I can read clearly for long time so if I increase from -1.5D to -1.75D will I get better reading vision ?

2>Will this increase to -1.75D will decrease my intermediate range, so I may need glasses for computer work, based on the ditance from computers ?

3>Should I expect more clear vision in reading after few more days with -1.5D or this is pretty much I should expect for reading

Have a Great Holidays!

-Regards

Hello,

So today I got test contact lens to create mini monovision, with difference of  -1.50 in my left eye compare to the power of  that eye. My left eye has
Power of -5.5, instead we got trial contact lens of -4.0, to create mini mono vision for -1.5. We can still adjust power of contact lens in order to come get best mini mono vision I would like and then we will use that power to test min monovisin for few months.

So it seems to be working fine, except that some of the characters in some text looks mixed up(meaning, not much space between them) when viewed with the both eyes, but when I look via left eye only, it seems fine,
so I am assuming it will get better over time to get the same vision with both eye opened as I am getting it with only left eye opened ( left eye has mini mono vision), is this true ?

-Thanks,
