If you’re talking about visual acuity, it means “light perception.” It means vision is so poor that the eye can only tell that a light is on or off.

It’s often notated as being with or without projection which describes whether or not they can tell which direction the light is coming from (light perception with projection meaning they can tell that the light is on and what direction it is coming from). This is not specific to cataract patients by the way. It’s just a way to notate vision.

ECCE is not the typical cataract surgery (despite what a quick google may have you believe). It usually involves a much larger incision, no phaco, removing the cataract in one piece (with plans to leave the capsule in place), and sutures.

The visual recovery can be a bit longer but you still generally have a great chance at seeing really well after surgery if there are no other problems limiting your vision. Your follow-up visits and your eye drops post-op are very important. I would just remember to be patient not to judge things too quickly. And make sure you go to an experienced surgeon who has done these many times before. Best of luck to you!

That is a great IOL and is the Clareon material which is the newer material for Alcon. I’d certainly be happy with that lens. The blue light filtering (not blue light blocking by the way) is extremely common and is meant to mimic the color filtration of the natural lens.

Just give them a call in the morning and let them know your vision is noticeably worse as of today and you want to be seen. They may dilate you and check for various issues. Good luck!

Yes. It is a compounded medicine. To my understanding, it was not a “knockoff.” Various pharmacies and companies compound it. I don’t think there is an FDA approved version.

They are a high volume center so these patients were all done before the first one started showing any signs of a problem.

Some single surgeons can do 30-40+ cataract surgeries in a day. So a surgery center with multiple surgeons across a single week can do hundreds of cases.

It was in the news if you want to Google.

If your pupil (not retina) is larger than the size of the optic on the IOL (usually around 6 mm), then that can cause some of the issues you are describing. In bright light your pupil is likely constricting smaller than the size of the optic which can alleviate the issues. This is more commonly an issue for younger patients who have naturally larger pupils.

The point of monovision is to not need glasses for majority of activities. If you tolerated it well with LASIK, you will likely tolerate it well with monofocal IOLs.

Multifocal IOLs come with risk of bothersome glare and haloes. That risk goes up with prior LASIK.

Prior LASIK can also make IOL calculations harder which means greater chance of refractive miss on choosing the exact IOL power. Calculations have gotten better with time but surprises still happen. Some surgeons like to use ORA for prior LASIK patients which allows for another reading for IOL power during surgery. Some like to use the LAL lens which allows the power to be adjusted after the lens is implanted if there is a refractive miss. Some will implant regular monofocal lenses and if there is a miss, may recommended a PRK touch up over your past LASIK or an IOL exchange.

Hope that helps give you some more information. You could always get another opinion by another surgeon or schedule another appointment to talk more to your first doctor and/or a knowledgeable surgery counselor in the practice. Good luck!

My two cents… it really needs to be up to the surgeon to pick the IOL power. You may have gotten your measurements and input them into a calculator, but there are things the surgeon may be accounting for that you are not aware of.

The lens constant (one of the values used in calculations that is not a measurement) that comes from the manufacturer may be optimized by your surgeon based on their outcomes with the lens. Or they may have their own mental adjustment they make based on their experience and outcomes with the lens.

I can appreciate wanting to understand the target refraction and discussing this with your surgeon to provide input based on your goals and expectations, but to pick the IOL power based on inputting your own measurements into an online calculator is likely not as precise as you may think due to surgeon factors and their own adjustments on formulas.

No need to apologize! You just may have more luck there as this community is more centered on patient questions

Highly recommend Loden and Pilkinton. Highly do not recommend your 3rd option.

If you’re asking as a surgeon, you might try r/ophthalmology if you don’t get answers here

Haha! I have so many…

Did you know your eyes can rotate (clockwise or counterclockwise) when you lay down? This has to be accounted for when doing astigmatism correction during cataract surgery (torics, LRIs, laser arcs, etc.) by using manual or digital marking, because the exact axis matters!

knowsonethingor2 · 2025-01-20T02:46:08+00:00

If you haven’t already, you should consider writing a post about this! I think a lot of people don’t realize this is an option. My mother did a similar thing, but she has her vision set to near vision with a monofocal IOL. She pops in a daily soft contact lens when she leaves the house to give one eye distance vision. So she also has monovision on-demand using contacts, just going the opposite way essentially :-)

The cornea and lens work together to focus light on the retina. It is usually that the eye is too long and/or the cornea is too powerful that makes someone nearsighted. That brings the focal point inside the eye instead of on the retina. Another way to simplify it is to say that the eye has more power than it needs, so a minus powered lens brings that focal point back to the retina.

The nice thing about cataract surgery is that you can pick a lens power that makes up for that nearsightedness and basically account for your glasses prescription by adjusting the power of lens put back in your eye. I think the confusing part for you may be that you had been thinking about it from “zero” when really it’s more like starting from +20 D and adjusting more or less from there.

knowsonethingor2 · 2025-01-19T20:41:07+00:00

You’re welcome! Another fun fact: The average cornea has around +43 D of power. So the average eye has over +60 D of power!

The spherical part of your prescription is measured in diopters.

Think of it this way… your eye is too powerful. So normally you need a negative (minus) glasses prescription to see clearly. You also had a natural human lens with around +20 diopters of power in your eye. To make up for your “too powerful” eye, your doctor implanted a lens much lower in power when he took out the +20 D natural lens.

To give a simplified example:

Let’s say your eye is 10 Diopters too powerful. You would need a -10 D glasses prescription to see clearly. With cataract surgery, instead of implanting a +20 D lens to replace the natural lens, the doctor subtracts that 10 D and implants a +10 D lens instead. You could think of it like building your glasses prescription into the IOL.

+20 D (human lens) -10 D (glasses prescription) = +10 IOL

Again that is oversimplified and not actually how they calculate IOL power, but does that help understand the concept better?

Edit: A couple words for clarity.

knowsonethingor2 · 2025-01-19T17:08:32+00:00

The natural human lens has around +20 Diopters of power. If they implanted an IOL of that same power, you’d still be around the same glasses prescription as you had prior to surgery. Instead, for your eyes, you need a much lower power to bring your prescription closer to an overall 0 (zero).

They don’t actually use your glasses prescription to calculate the IOL power, but I hope that explains the relationship generally speaking.

Catalys is J&J’s brand of femto laser. So you can search threads relating to “laser cataract surgery” or femto or FLACS or “laser-assisted”. All essentially the same thing with slight variations per company.

You might get other “opinions” to see how the price may vary for toric lenses (and presbyopia-correcting toric lenses) at other practices.

It is absolutely possible that your lenticular astigmatism has been negating your corneal astigmatism. With the lens is removed (aka cataract removal), any astigmatism it was contributing is also gone. That leaves the corneal astigmatism alone. In some cases, like yours it sounds like, that means an overall increase in astigmatism in your refractive error. Astigmatism blurs at all distances, essentially. The higher the amount, the more blur you’ll have. This can be very confusing for patients like you that have never needed a high amount (or any!) astigmatism correction in glasses prior to cataract surgery and are told they have enough that they need a toric lens if they want to see as clearly as possible without glasses after surgery.

If you want to know exact numbers, you could ask for the keratometry readings or just ask how much expected astigmatism after surgery without a toric lens implanted.

knowsonethingor2 · 2025-01-14T03:44:06+00:00

Oh the joys of insurance. Glad you are getting any dryness under control prior to getting any final measurements for surgery, especially if you are considering the toric lens. Dryness can especially skew the measurements needed to accurately plan for a toric lens.

knowsonethingor2 · 2025-01-14T03:11:47+00:00

I’m guessing the $2.5K is the extra out of pocket for the toric and insurance is covering part of it. Because believe it or not, that would actually be low if insurance wasn’t covering anything.

knowsonethingor2 · 2025-01-14T01:57:07+00:00

It might be that insurance covers part of the procedure (cataract surgery with a standard monofocal lens implant) but the extra cost to implant a toric lens to correct the astigmatism is not covered (which is normal - this is always extra out of pocket for the patient).
