Mildly Myopic non dominant eye only

I think -1.25 D with a pure monofocal like a Clareon or Tecnis 1 will leave you a little short of reading ability, that you may regret down the road. With a monofocal you may want to consider -1.5 D instead. If you want to go with less myopia, then I would suggest the J&J Eyhance. It gives about 0.35 D of extended depth of focus, and you could get away with -1.0 to -1.25 D if that is what you want. Despite what J&J may say, there is some loss of contrast sensitivity and ultimate distance visual acuity, but I suspect based on the data, it is not much. It is an option unless your surgeon is an Alcon only type. Yes, surgeons do seem to land in the Alcon or J&J camp, and not many do both. The Eyhance will not give you the amount of extra depth of focus that a Vivity will, but it also has less of the loss of contrast and halo risk. That said, I believe there is nothing wrong with a pure monofocal at -1.5 D.

.

And the other thing to keep in mind is that you cannot select exactly -1.25 D or -1.5 D unless you get really lucky. These IOLs come in steps of 0.5 D measured at the lens plane. This converts to about 0.38 D steps at the cornea or eyeglass plane. For that reason to be realistic one should target a range that you would be happy with rather than a specific number. But, to go into surgery with all the cards on the table face up, you should ask for a copy of the IOL Calculation sheet. You can see an example of one and an explanation of what the measurements are if you google this:

.

This will let you know what the actual choices are with your eye. I would also suggest you may want to use your eye measurements to do an independent check of the power calculation. The calculators can be found on line. Since you are an engineer I don't think you will have any trouble using them. Two I would recommend are the Hill RBF V3.0 and the Barrett Universal II. Both are highly rated for accuracy when targeting an under correction. It gives you a second and third opinion on what your outcome might be. If you are debating between the available steps having a couple more opinions can make it easier. If these calculators do not run for you on Google Chrome then try Microsoft Edge.

FWIW, I am not sure of any benefit in using a laser for the incision. It probably does no harm, but I have not seen any consistent benefit reported for using it.

.

You will not have much difference between the eyes, and while you are waiting to do the second one, there is not likely to be an issue based on my experience. I did end up using a contact in my non operated eye though, in preference to glasses.

.

One last comment. Don't rush into this thing, and if you do not have all the loose ends tied up, delay it until you do. It is a lifetime decision that you only get to make once, unless you are prepared to do an explant.

Thanks! I"m OK with the laser if she wants to use it since there's no harm in it. She is Alcon only and said -1,25 but commented about the 0.5 steps. I've tried contacts 4 times and hate them. I just can't stand having something in my eye let alone air blowing on them. It was years ago but the only ones I could wear were so thin I could blink and they'd crumple and fall out. Also too much maintenance vs glasses.

.

Yes they will provide all the calcs and I or my wife is going to sign off on the lens. I'm fine with where I am at this point and will immediately pull the plug if something changes.

Regarding Contacts -- it sounds like you weren't fit with the proper lens. When they fit properly, they don't crumple or fall out - and you can't even feel that you're wearing them............. When I first started wearing contact lens, I had to try many different brands before I found one that fit me. For example, I could never wear Acuvue -- it felt like something was caught in my eye all the time. .. But when I tried Freshlook Dimensions - and later Bausch & Lomb SoftLens multi-focal lens - they were terrific. They're easy to insert, don't dry my eyes, and I can't feel anything when I'm wearing them. So, I suggest you try again - with different brands - until you find the one that fits your eye. Everybody is different.

... .. When I developed a posterior subcapsular cataract in my non-dominant eye last year, I had the cataract removed and a PanOptix lens put in. But I continue to wear my contact lens in the dominant eye - until I have the surgery on that eye done later this year.

The reason I suggest getting the calculation data sheet ahead of time and doing your own calculations is that there can be a less than obvious choice to make, that may be hard to live with the rest of your life. Getting the numbers after surgery is too late, like shutting the barn door after all the horses are gone.

.

For example with a nominal target of -1.25 D the real choice with your eyes may be -1.06 D or -1.44 D. The average of these two choices is -1.25 D, but you cannot choose that outcome. You have to go with the lower one or the higher one. If it were me, I would go with the -1.44 D based on my experience, as I ended up at -1.40 D and like it a lot. I suspect I would be much less happy with -1.06 D. I would be reaching for my readers on a much more frequent basis. The point is that you should participate in that decision.

.

And the second part of it is that your surgeon may only be using one formula. If you use Hill RBF (probably the most accurate one), you will get another number, and if you use Barrett Universal II you will get another number. Put it together and you will get a range of what to expect with each of your two choices.

.

In the cataract business getting an unexpected outcome is called a "surprise"! These are the things you can do to reduce the odds of getting a less than desirable "surprise".

Good Morning! I was going to just write -1.5 earlier as that would have been more accurate but as you state not correct either. Thanks for laying it our perfectly. We discussed the first day that she uses multiple formulas. I can't remember which but in later discussions we touched on multiple formulas how some are more accurate and even if we hit the target dead on at exactly where I am now what I see will be different due to the lack of accommodation in the IOL. And yes calcs before surgery.

I tried contacts probably 30 years ago. I'm sure a lot has changed since then. I might give them another try but there's nothing more convenient than having my progressive or non progressive transitions since all I ever need to do is either take them off or put my sunglasses on when driving. I'm light sensitive so I love transitions. I just wish they were as dark when it's warm out as they are when it's cold.

I started wearing contacts around 1975 and stared with a pair (yes 2) contacts from B+L which cost me about $350. Had to boil them every night and remove protein once a week or so. They were a pain. Much more recently I got some Acuvue Moist contacts. They are hydrogel material and they were awful. They were like trying to put a circle cut out of Saran wrap in my eyes. This discouraged me from wearing them and I gave up on contacts.

.

When I got into this cataract thing I did a lot more research on contact materials and found that there was now a newer material called Silicone Hyrogel. They are stiffer and easier to handle, but still are comfortable. They have very high oxygen permeability. I tried several types and found these ones the best in order for me:

.

1. Kirkland Signature (CooperVision MyDay)
2. Alcon Total1
3. Acuvue Oasys Daily

   .

   I think it is the material that makes the difference between good contacts and poor ones. The straight hydrogel ones are cheaper but not nearly as good, at least in my eyes.

I had my 1 week follow-up yesterday. -1.5 in the left eye which really is a good compromise as I can make out even the tiniest print if I adjust my arm properly albeit several inches further than previously. Binocularly is even better near range.

.

I do have a little flashing going on in the periphery and a little other positive dysphotopsia that the Optometrist says is probably from the edge of the lense and will go away or I'll get used to it. I don't get any of dysphotopsia at night and night driving is wonderful with no discernable difference (at night) between my eyes. Right eye, although a tiny but yellower than the left is such that I'm not going to get it done anytime soon. In the meantime I feel as though I got the result I wanted and if the dysphotopsia doesn't go away I can live with it because my vision is so much better than it was I'm very happy overall and appreciate all the input.

The day after visit went well. MD hoped I wasn't freaked out by being able to see everything which she said was extremely rare. I thought it was fascinating! Based on my ability to read papers on my desk as well as my screen it looks like we hit -1.5! Will know more during the 1 week check up. Only thing is I have some intermittent flickering going on which I hope goes away but it's better than the cataract's greasy blurry starbursts. Right eye is a little yellow but since I no longer do color matching it doesn't bother me at all. Old pair of progressives are working fine since the old brain just uses my dominant right eye.
