Vision problems and cataract surgery

[cvanc]

Hi all-

If you ask me I'm too young for this!  Nonetheless I'm getting cataracts removed soon.

I wonder who here has BTDT and how it has (hopefully) improved your eyesight in general and specifically the ability to work up close and personal with PC boards etc.

I think I've found a good doctor and we've discussed getting a pair of higher grade implants.  My main symptom is not softness, it's double vision, and it has really been slowing my bench work down.

Anyone been through this?  Thanks.

I had both eyes done a few years ago. My problem was a lack of sharpness. Vision was getting blurry so I went in for an eye exam and new lenses. But after the exam he said my corrective lenses were already about as good as I could get and the blurriness was due to cataracts.

He recommended an outfit in the nearest large city that specialized in cataract and Lasik surgery. All went well. They did my left eye first and then a few days later my right eye. Had to wait about a month before getting new prescription for glasses that matched my post surgery vision.

This place had the procedure set up with assembly line precision. The entire process took a little over two hours. Most of that time was a series of eye drops to do various things with waits between each one. The actual surgery takes just a few minutes.

The results:

1) sharper vision. The blurred vision was gone.

2) With cataracts looking into lights is like driving a car towards a sunset with a dirty windshield. One of the preop tests measured that and it was obvious to me what the test was showing, and that my left eye was quite a bit worse.

3) Cataracts have a yellow tint to them. The day after each eye was done, I had an eye exam just to make sure everything was OK. After the first when my left eye had been done, the eye doctor said he wanted to show me something. The wall in the exam room was a dark violet color. He had me look at it with only my left eye. It was a dark violet. Then with only my right (not done yet) eye and it was gray! Was I surprised. I repeated that comparison that evening looking at a spectacular sunset. Spectacular with either eye, but with the left eye the sunset had blues that were missing with my right eye.

BTDT, problem was milkyness in my vision and really bad night vision. Got a plastic lens implanted, which gave me a whole new experience.
What you need to know is, that plastic lenses have a fixed focal length. I'm short-sighted from birth, so I need long-distance glasses for driving and everyday use, special glasses for computer screen vision, and no glasses for close up vision (like the boards you mention).
But never mind how your focus is, you'll most probably need at least two pairs of glasses.
It's bit of bother, but you'll get used to it and enjoy your new sharp view of the world.

[cdev]

Have you tried (commercial, not home-made) carnosine eye drops?

[rhb]

I was a high myope from birth.  -11 to -12 lenses at 20 something.  I've had 6 eye surgeries.  Two vitrectomies for detached retinas.  One due to a blow to the eye with my wrist while adjusting the clutch on my pickup.  The other spontaneous.  Both retinal guys did a good job.

Unfortunately, cataracts appear to be an inevitable consequence of having the inside of your eyeball removed and it then filling with liquid.  The first cataract surgeon (primarily a retinal specialist) did a fine job on my right eye.  The surgeon who did my left eye botched it badly.  Lots of damage to the lens capsule, but worse than that, he didn't put the lens in the capsule.  So it was flopping about in my eye and causing very high pressure.  I was able to get it fixed by a surgeon at Baylor in Houston, but naturally he could not fix the damage to the capsule. So I then had to have a hole made in the capsule with a YAG laser.

End result is the left eye is usable for ordinary tasks getting around the house, etc, but the vision is poor enough that I really don't have good depth perception.

It's *really* worth looking for someone who only does cataract surgery.

The good news is I can still see which would not have been the case 100 years ago.  The bad news is I also have glaucoma.  So at 65 I'm in a race between dying and going blind.  I'm hoping dying comes first, but Dad lived to 91 and Mother almost to 96.  So I rather fear going blind will win :-(

[Nusa]

I haven't, but my father had cataract surgery about 20 years ago. His cataracts were bad enough in both eyes that he was blind in direct sunlight....a real danger when driving. He was originally very near-sighted and was also old enough to have age-related near-focus issues, so he elected to get lens designed for good distance vision. He needs glasses now to do close-up work. It's worked out well in his case. He's still going at 87, and while he has some health problems, his eyes are working fine.

[cdev]

I made a long post earlier about how I make my own eye drops which seem to help my eyes, using a substance called l-carnosine. Commercial eye drops exist which are useful for people as an alternative to surgery. There are tons of things that may be protective to the eyes or reduce the rate of various age related insults to the eyes and nerves generally, and they are documented on PubMed to various degrees. But I shouldnt be the one advocating them, people should look at the big picture and learn how to use Pubmed.

This describes me almost perfectly.  My optometrist is starting to make noises about cataract surgery and how it will eliminate my need for glasses altogether.

How does that work?  As Benta said, plastic lenses only focus at one distance so how will you see clearly at other distances?

Ed

[wilfred]

I went for distance lenses so I could drive, walk around and watch TV. I wear glasses for computer and reading.

I found it a quick and straightforward experience. As others have said it is the waiting around on a trolley with a sequence of drops being put in your eyes that was the time consuming part. The actual surgery was very quick.

And if you were to ask me I also thought I was too young for cataract surgery. But there are different types apparently.

Anyone thinking about, just get it over and done with. I was a bit worried beforehand but as is typical of things I worry about, I needn't have.

[Tom45]

Ed

For most people that need cataract surgery, they are old enough that they can't readily focus at various distances. So they have to use multifocal glasses, or reading glasses anyway. I've been wearing tri-focal glasses for many years, so the only difference after cataract surgery is that the prescription has changed.

Tom

[rhb]

The focus for both my eyes is at about 3 ft.  That turns out to be quite convenient.  I normally don' wear glasses unless reading, etc or driving on a long trip where I need to be able to read road signs at driving speed.

So I have lots of cheap readers and a pair of distance glasses for driving.  I am going to get a pair of bifocals, but it's not been high priority.

Setting the focus for a high myope is rather hit or miss because of the difficulty measuring the length of the eye.  I've become slightly more near sighted since the surgery and have shifted from 2 diopter readers to 1.5.

This is a US-based study that was done on dogs with eye drops containing n-acetyl-carnosine.

Dogs seem to be particularly susceptible to cataracts.

The effect of a topical antioxidant formulation including N-acetyl carnosine on
canine cataract: a preliminary study.

OBJECTIVE: To determine the efficacy of a topical antioxidant formulation
including N-acetyl carnosine in the treatment of canine cataract in a preliminary
nonplacebo, controlled, unmasked study.

ANIMALS STUDIED: Thirty dogs of varying breeds and ages with a spectrum of lens
opacities ranging from nuclear sclerosis to total mature cataract.

METHODS: Dogs were treated three times daily with topical 2% N-acetyl carnosine
in a buffered vehicle containing the antioxidants glutathione, cysteine
ascorbate, L-taurine and riboflavin (Ocluvet, Practivet, Phoenix, AZ, USA). Dogs
were examined prior to treatment and at 2, 4 and 8 weeks during treatment, by
direct and indirect ophthalmoscopy and slit-lamp biomicroscopy after
pharmacologic pupil dilation. Photographic documentation of lens opacity was
achieved by retroillumination photography, with three photographs taken at each
examination time-point. A lens opacification index (LOI), determined by
integration of the grayscale level of each pixel across the image, was evaluated
by computerized image analysis of digitized images. Alteration in mean LOI was
determined for each animal, having normalized the initial LOI.

RESULTS: Fifty-eight eyes of 30 dogs were evaluated, 22 with mature cataract, 13
with immature cataract, 9 with cataract associated with other intraocular disease
such as uveitis and 14 with nuclear sclerosis alone. One dog was unilaterally
anophthalmic after previous enucleation and one had a phthytic eye after previous
uveitis-induced glaucoma. Image analysis showed a reduction in mean LOI in all
cataract groups (mean resolution in opacity of 2.3 +/- 0.33% for all cataracts),
although this was only statistically significant in those eyes with immature
cataract (mean resolution of opacity 4.5 +/- 0.33%) or nuclear sclerosis (mean
decrease in opacity 5 +/- 0.37%). Reduction in lens opacity was seen in eyes with
mature cataract (0.5 +/- 0.4%) and in miscellaneous cataract associated with
intraocular inflammation (1.3 +/- 0.4%), but these changes were not statistically
significant. Owner evaluation of visual capability, however, suggested
improvement in vision in 80% of cases by the end of the study.

CONCLUSIONS: This study demonstrates some marginal reduction in lens
opacification in a substantial number of cases of canine cataract with the use of
a topical nutritional antioxidant formulation including N-acetyl carnosine. Lens
opacification was improved with treatment in eyes with immature cataract or
nuclear sclerosis while in eyes with mature cataract or cataract with associated
intraocular inflammatory pathology less reduction was seen.

It doesn't work quite that way. The eye focus length from around 6 ft to infinity is appr. the same, and if you have both eyes done, you can go for this. If you so, you'll need glasses for computer use (2...4 ft.) and glasses for reading (1...2 ft.).
If you're only getting one eye done, it makes sense to align the two eyes to appr. the same dioptries.

[rhb]

They now sell deformable implants.  As my eyesight is very dear to me, I went with the hard acrylic lens which have the longest track record.  But they market the deformable lenses a treatment for presbyopia,

[VK3DRB]

I also had cataracts at a youngish age, which got progressively worse over time. My previous role was an electronics engineer in the medical industry working on developing ophthalmic products, and fortunately I was working on a project with the Director of Ophthalmology at the Victorian Eye and Ear Hospital. He is the best in the field. I got a great deal from him and got them removed. My left eye now has a lens put in it with a focal length of infinity. The right one has a focal length at arm's distance. The result is I do not nee glasses except for working closely on electronics.

With different focal lengths, the brain switches from eye to eye automatically after a while (takes up to 6 months for this to occur). I can see clearly close or far away. Fantastic and highly recommended.

After cataracts are removed the weirdest sensation is everything so bright and white is incredibly white!

[cdev]

n-acetyl-carnosine eye drops do appear to reverse the loss of opacity from cataract to some extent. The change is lasting.

They are currently available OTC for both people (expensive) and pets (cheap)

How does the cataract surgeries work ? is there pain ? how do they stop your eye from moving ?

scary sounding stuff

They give you a series of eye drops over roughly an hour. I don't know what all the drops are for, but one result is that the eye muscles are paralyzed. You just can't move your eye. Before the surgery I was also sceptical that I'd be able to keep my eye still.

The actual surgery consists of making a tiny incision to remove the original lens. And then insert the new lens. This takes just a minute or two. Strange to see this happening. A blurry light show for a short while and then it's over. There is no pain from the surgery.

Definitely scary sounding. Not so bad in actuality.

[digsys]

I had the same procedure on my left eye ~5 months ago. Eye drops to numb it, a patch over the right eye .. weird blurry lights :-)
There was bruising for several days, but no pain at all that I recall. No driving for a few days, as the eye must stay covered for ~2 weeks, and eyedrops
twice a day. Not that bad at all .. Results ....
I went from ~ 20:38ish to 20:12ish. A white object with my left eye was IN FACT YELLOW with my right !! All greens and blues were INTENSELY more vivid !
I kept stopping at parks and literally counting leaves on the trees !! It was bloody awesome ! Stoopid body has now adjusted, and all is "normal" now :-)
Even so, I can see street signs at night, with oncoming headlights waaay in the distance. Felt like I almost had X-Ray vision :-)
WELL worth it !! I was thinking of doing my right eye with either a dual lens of a fixed closer focus one, like one reply here. Still mulling it over.

[VK3DRB]

They work wonders. Pain like sand in the eye for a few hours - best to sleep it off. Next morning, all is well and you will smile when the eye patch is removed. You have to put in eye drops a few times a day for a month.

You have the operation whilst awake - somewhat drugged. I never taken illicit drugs in my life and only been drunk on alcohol only once. But I can understand what getting high is like, after being partially anaesthetised for an hour or so. I was telling the ophthalmologist about the processor in the XBOX 360 whilst having the operation. I could see the needle go into the eyeball and the lens unwrapping though the cannula.

It was cool! Nothing scary. The risk is very low if you go to a good ophthalmologist. Just do it!

[vtwin@cox.net]

Ophthalmologist told me I had cataracts two years ago (at 52). Other than things being blurry (which, since I have astigmatism, I'm used to anyway) I hadn't noticed them (was surprised when he told me).

I have to find a doctor who will put me out while they do the procedure, even if it means I have to pay out of pocket for the anesthesiologist. There is no way I could be awake for it, even drugged.

I know a few people who go for injections in their eyes for macular degeneration. Beats going blind, I imagine, but I'd hate to think about the amount of drugs I would need for them to give me to allow them to do that to me.

[cdev]

When I posted the other day I was fairly sure that somewhere in my stuff I had some old Russian literature about the use of carnosine (not the patented n-acetyl-carnosine) for cataracts.

One journal article is from Biokhimiya (Moscow) from 2000. I don't have a complete copy, just its abstract handy. But I am pretty sure its on the web, just a bit pressed for time now. (Edit- Link added)

Free radicals and aging
Since American scholar Harman [10] pointed out that free radicals may be one of the important factors causing aging and aging diseases.
This theory has gradually been recognized by many scholars around the world.
Many findings have clearly shown that the emergence and development of aging and aging diseases are closely related to cellular damage caused by oxygen free radicals.
Related, it causes cell instability and loss of function, leading to the emergence of aging and aging diseases. Atherosclerosis,
Diseases such as diabetes [11], Alzheimer's disease [12, 13] and aging cataract [14, 15] are associated with free radical damage.

publishing).

In addition, we use myopeptide eye drops to treat patients with varying degrees of visual impairment (no cataract) from 48 to 60 years old.

. The treatment period is 2-6 months. The experimental results show that carnosine can alleviate eye fatigue and improve vision to some extent (If you give a clearer view, you can significantly improve your vision). Patients say that carnosine can brighten and relax their eyes. also It is important to note that the medical applications of these carnosines are of statistical importance.

Therefore, carnosine is a potential drug for the prevention and treatment of aging cataracts and delaying visual aging (a sign of aging). Pharmacology of carnosine
The effect seems to be that it can be immersed in the lens [14, 23], improve the antioxidant capacity of the lens, increase the nano-, potassium-triphosphate

It really does amazing things for the eyes. A pet version is available in the US, for around $50 for a 15 ml bottle.

Or you can make it yourself fresh every couple of days using distilled water, a bit of sterile salt, a tiny bit of sodium bicarbonate (baking soda) and a very tiny bit of l-carnosine. It improves vision dramatically and the results are lasting, its not like a drug - the clarifying effect lasts, it doesn't wear off.

Unfortunately, I still have myopia, and some other eye issues. But, Ive had them for a long time. The above paper is true, it does improve vision substantially.
