Going for Mono vision Lite, advice needed.

Extremely helpful, thank you.

1. I am very happy with the RE distance mono focus. I am typing this w/o glasses at app 30"(page at 120%) but that has improved from a few days ago and past that it's sharp crisp and clean looking.

2. The limited near range is due to the cataract, Based on info from Zeiss website, IOL focal point distances are: near-15.748" Intermediate - 31.496 And far - Beyond 39.370" So I must have limited near. The problem is when I look up and out, I can feel the LE blurriness and it's disorienting, hard to explain it. It could very well have too much difference now, but that will change with the LE correction. Being able to use the computer just happened, that issue is been resolved.

3. Just so I'm clear on this, what is the difference to my vision if I land closer to .75. Will it be taking away from distance but not really helping with closer vision?

When I was discussing with the surgeon if he thought it was a viable plan to want the Le set for intermediate, he said yes, that's why they suggested it. I told him they never offered it as an option. They put me in for Panoptix, even though I never committed to any option.

One more thing, the follow up appointment was not with the surgeon. This doctor told me how I see distance(the chart simulating 20') is exactly how my LE set to intermediate will see but my LE is now focused 12"-14" which is slightly less than having a IOL set to near. Won't the new intermediate IOL improve distance at a loss to near compared to where I am at now?

Your right eye sounds about right for a distance monofocal IOL. With monovision you mainly get distance vision with the distance eye. The nearer eye will contribute some but not a lot. Your brain will learn to ignore that eye at distance, and ignore the distance eye for close up. At more intermediate ranges it will use both eyes. Here are some impressions of what varying degrees of under correction may look like.

.

Under 0.25 D - this is the normal target for distance vision and should achieve 20/20. They don't like to target for 0.0 D as they may miss and go positive (far sighted) which hurts reading distance vision.

Under 0.5 D - This would be very mild monovision, and would not impact distance vision much, and I suspect many people would not get glasses for this much near sightedness. However it won't help reading much.

Under 0.75 D - This would likely be enough to see a computer screen at 15" or so, and will impact distance vision some. Reading text on paper may still be difficult.

Under 1.0 D - Perhaps ideal for a normal sized computer screen, but still difficult with smaller text. Will impact distance vision some, but you are likely to ignore it.

Under 1.25 D - This is probably enough to read smaller (10 point) text on paper, but still works for a computer screen. Fairly crisp out to 25" or so. Probably down to 20/40 to 20/50 at distance, but again your brain will mainly ignore it.

.

I suspect the narrow range you are seeing now is due to the cataract. My close -1.25 D eye now sees pretty crisp images from 6" to 25".

Going in 2 days for LE . I will post after surgery with results of my mini mono vision. While it won't change my decision, is there any type of correction available if the end result is too much?

Basically if you go for "too much" anisometropia you will be mildly short sighted in one eye. Correction would be with eyeglasses or contacts. If you go for "too little" you will need reading glasses more often. I think the ideal amount is when you almost never need reading glasses or prescription glasses.

Thank you again, hoping I land in the sweet spot. See you on the other side...........................

2 days out, a little early to tell where I'll end up but texting without glasses now app 12" out. distance appears good too. So far very satisfied with this option.

Dominant RE set for distance,

power 18.5D, LE set for intermediate, power 20.5 D.

What do these mean? from a card they gave me from the lens implants. Bausch & Lomb model A060?

That all looks good. The power of the lenses implanted have to replace the effect of the natural lens plus correct any error in the cornea. You can't tell much from the power of these lenses. The real test will be when you get your normal refractive eye test done by your optometrist. Then you will know where you are at relative to plano, and what residual astigmatism there may be. It is best to wait until the 6 week mark if you plan to get eyeglasses. By then the operated eye should have settled down. Your surgeon may want you to see the optometrist earlier than that to do a check that your operated eye is looking good.

If you google the following should be able to find and download a reading test pdf to print off. It is useful to check your reading vision. With it and my -1.25 simulated monovision in brighter light I can read the smallest No 1 section.

4 weeks out from RE dominant for mono focal distance and 2 weeks since LE mono focal intermediate.

I have not needed glasses since.Reading and texting at about 12 inches out.

Wish I had the same distance in both but not needing to carry around glasses was worth it. Thats the compromise, very happy so far. I was terrified going in, not knowing where it going to land, had to make this decision without test driving. Thanks to all who helped me through this.

Will update after the final exam

Glad that it has turned out well. The next best measure of the outcome after your own satisfaction is the prescription for eyeglasses. It basically indicates where you have ended up. That said, if you are reading at 12" that has to be very good. If you do plan to get glasses I would wait until 6 weeks after your second eye before you get the eye exam for your prescription.

Quick update, using the phone for texting and reading, it's held closer to 18", not 12". I can read line 1 of the Jaeger eye chart at about 20". Still adapting to the difference in focus, especially in the distance vision.

Follow up exam, 6 weeks + from 2nd surgery, non dominant LE, set for intermediate. I have not needed glasses since for my everyday activities, working in front of a computer, phone use, texting, reading, home construction projects, cooking etc.. so very happy about that. I don't drive very much at night, and I can without any major problems but I wish I had the strong distance vision in both eyes for it but that is where the compromise comes in.

Can't have it all. If I close my left eye while reading or using the computer it's a reminder of where I would be with mono focal both set for distance, then I am thankful for the mono vision I selected.

The optometrist said I landed 1.25 diopter difference. If I choose to get reading glasses they gave me these stats, not sure what they mean. RT sphere +.25 Cylinder SPH Add +2.50

LE sphere -1.25 Cylinder -.50 Add +2.50

If someone can explain that,I'd appreciate it

So from my experience, if you don't mind needing glasses for close up (within app 2.5 feet) Mono focus set to distance is an excellent choice.

If you want to be mostly free of needing glasses, then mono vision option should be explored

It sounds like you got very good results for monovision. Like you say monovision is not perfect, but I find it very convenient not to need glasses 95% of the time.

.

With respect to your prescription for glasses I will do the best I can from what I understand.

.

RT sphere +.25 Cylinder SPH Add +2.50

.

This would be your distance eye and it looks like the surgeon overshot slightly to leave you +0.25 D far sighted. I believe the lenses come in 0.5 D steps of power, so the better choice would have been to leave you at -0.25 D or slightly myopic. That would give you somewhat better reading ability with that eye, For distance +0.25 is going to give you about the same vision as -0.25 D. So the only loss is for closer vision not on distance. I do not understand what the SPH stands for other than it may mean spherical with zero astigmatism correction is needed. The Add is the standard +2.50 for reading when your distance vision is perfect.

.

LE sphere -1.25 Cylinder -.50 Add +2.50

.

I think you got near ideal correction for this closer eye with the -1.25 D. The Cylinder of -0.5 is very good. Normally there is an angle associated with this which you will need if you get glasses. The Add of +2.50 surprises me a little. Since your distance is -1.25, I would have expected the Add for that eye to be +1.25 D instead of +2.5. But I am no optometrist... However, if you are going to invest in progressive glasses you may want to check that Add number with your optometrist. One thing I find when trying to use off the shelf reading glasses with both lenses the same, is that my distance eye gets corrected well, but my nearer eye gets over corrected for reading.

I made an error in my previous comment. Edit feature does not seem to be allowed.

.

That LE Add is correct as it is at +2.5. Your -1.25 myopia is being corrected with the distance part of a progressive so the full +2.5 is still needed for reading.

.

My thinking remains the same for off the shelf reading glasses. If you want to use them you will have to pick a compromise between what your right eye wants and what your left eye wants. Somewhere around +1.75 may be about right.

Thank you AKA,

One thing I noticed driving last night, my LE set for intermediate, sees oncoming headlights in the opposite lane with a long vertical streak of light above and below the source. I am aware of this now inside when I close my right eye and look at a point source of light. Very faint, but at night with the headlight or any point source light, closing the right eye it's very strong.

Is that normal for a fixed lens set to intermediate after only 6 weeks?

The eye that is set for closer vision is going to be slightly out of focus when used for distance. It is probably just that the image is out of focus, and you will have to depend on your brain to ignore that effect.
