Cataract surgery
« on: May 10, 2017, 10:02:46 pm »
Some of us are, inevitably, getting older. Stuff goes bad. Like an old amp. You can re-cap an amp. You can't re-route a pinched nerve, and sewing rotator-cuffs is if-y. But you CAN put in a new eye-lens.

Another guy and I were yacking. He has a cataract just starting. I shared my tale, he said it was "helpful", I figured others here may be in a similar position.

The lens in your eye can go cloudy. "Cataract". A severe cataract can be seen by others, but well before that you will be seeing badly. My vision has been going down for a few years. Eyeglasses-doc said I was not legal to drive even with best-correction glasses. (I also was not reading on the PC well, and that strain gave me a severe back/leg hurt.)

AFAIK, everybody loves when a ripe cataract is replaced. Only sad tale was a guy who didn't do his eye-drops and got infected.

The process is tedious. Eye-drops 4X daily for 5 weeks. Starts before the exam, because they need to see through the cloudy lens to figure what plastic to replace you with. There's also corneal curve and ultrasound measurements to cross-check the through-lens guesstimate. And they look for every other possible problem too. Dilation involved so you should have a driver.

(Warning: spoiler!) The actual surgery is trivial, although they prepare you like you might turn blue and flat-line. Wide-awake or with a Quaalude-like pill, but lots of numb-drop (lots of drops overall). Finally they roll you to the surgeon who does something at the edge of your eye. He pokes a while, there is a buzz to remove the old lens, something comes in, they take you out. Typically no stitches, the incision is that small. You get apple juice, they call your ride.

I could see better right away. Overhead lights, the wall-clock in the checkout room. Far from perfect, it has to heal, but the haze was gone and the focus was better.

Eye-patch that first day and at night for a week. They tell you to rest all day, and don't lift anything heavy for a week, eyedrops for a month. An exam to be sure no-problem, then a later exam for possible Rx lenses.

The basic lens is fix-focus. What little accommodation you may still have (probably 1.5d age 50-60) is gone- you can't focus closer with eye muscles. Typical goal is toward infinity. Like an Instamatic, this covers to maybe 4 feet. If ALL your life is closer, you can ask for that, but prolly not wise. There are "progressives" with near/far areas but cost more and sound annoying. A new flex technology hooks your focus-muscle and gets some accommodation back but is not generally available. I took the base option.

My bionic-eye vision is just fantastic! Better than I have been in years (I waited too long).

For PC and reading I use $3 readers. (Far better than the $200 specs I used to need to drive.) I *may* get custom readers for some residual blur, but I don't have to.

I hope you are on a good medical plan. The list-price for both eyes was over $6K! My ex-state-worker insurance paid ~half that, which the staff said was "very good". Out-of-pocket $30 for co-pays and maybe as much for Rx drops, $17 for five assorted readers. The cataract doctor staff seemed well-equipped to work with you to afford it.

Good info. Mom had both eyes done in the last year, mostly complained about the drops.


I just got my first pair of progressives (glasses) in Feb. I had put it off for several years. Overall they're fine, don't like 'em for driving though since I actually do check my mirrors constantly and have to tilt my head to get the focus right. Don't like going down stairs. It IS nice seeing what I'm writing or reading without taking my glasses off though. Still haven't nailed the mid-range for the monitor, but the doc said eventually muscle memory will take care of that too.


Hopefully, I make it the distance without cataracts. Glad your surgery went well!

growing older is NOT for the faint of heart!, glad you're tweaked in the good direction.

I just got my progressives this last week, still haven't arrived yet... I tried reading glasses, but I never remembered to swap them out... sigh. 

Good to hear about your experience, I'm sure I'm in for it, my mom had one of hers done, and I think she indicated she may have to do the other.

> Don't like going down stairs.

I have used several bi-focals for a decade.

When going down stairs, DON'T LOOK!!

If you others have not tried this yet: you can't see the far stair with the lower near-vision area, so you tilt your head, and tilt it some more. Which never works. Until you are falling. You have to learn to assume the stairs are there, and you know how to do stairs, grab the handrail (I'm real into handrails) and just go without looking.

> Still haven't nailed the mid-range for the monitor, but the doc said eventually muscle memory will take care of that too.

With progressives, there "should" be a mid-zone. But the whole optics of progressives is dubious and imperfect. The "right spot" may be in-focus but distorted or just too small.

On PC I much prefer single-vision, or bifocal with PC-range in the top (nearer on bottom for keyboard and calculator).

For any near distance, _if_ good (natural or corrected) for infinity, the "power" you need to see nearer is very simple.
1.0d = 40"
1.5d = 26"
2.0d = 20"
2.5d = 16"
3.0d = 13"
3.5d = 11"

My monitor is at 24-25", so I would expect to use 1.5d. (In fact I'm happy with 1.25d which shows my post-op eye is a hair nearsighted.)

EDIT -- Dollar General TREE sells readers for $1.00. They seem to be as-good as the $3 readers at the other stores or the $6 jobs at WalMart. The supermarket stocks $19.95 brand-name readers which are a bit better frames but hardly 20X better. I have not seen a gross optical defect. I suspect mis-marking happens, so if a "2.0d" does not look right at 20", maybe it's really 1.5 or 2.5.

grab the handrail
My "livin space" is upstairs, 12:12 pitch! with 10" runners!
I took a retired climbing rope, did a 3 braid and turn-buckled it tightish as my handrail. Offers great flex, grip and slows ppl way down not familiar with my stairs or hand-rope-rail.  And, ya, I don't look as much as feel and rely on muscle memory to guide the feet.

I have had progressives for about three years now.  It took me a long time to get used to them.  The sweet spot is small and the peripheral correction is nonexistent.  My first pair did not seem to have the left and right eye centers lined up properly... eventually the brain compensates--now, I hardly notice the regions that are out of focus.  The hardest thing for me is trying to see on coming traffic from my left side while trying to turn right on to the busy highway.


I've been considering trying traditional bifocals next time in an effort to get back some peripheral clarity.  I also hear they make bifocal contact lenses.

Good info, I'll have to learn this soon.  As for the contacts, I can't do them, tried... (before I got older and have lost my near vision) and my eyes are already just too dry.  I was putting eye drops in like every hour and still couldn't stand how irritated my eyes were.  I gave up after about a month.

They sure could be mis-centered. The doctor measures the distance between your eyes ("PD") (with a simple ruler, or with a box like a View-Master but no pictures), adjusts for the slight cross-eye in close seeing. I've had different PDs from different docs. Maybe my head is swelling and shrinking. More likely it is hard to read to a millimeter. For mild corrections in single-vision (or bi-focals) this hardly matters. But the "sweet zone" in progressives is broad for top/far, narrower for lower/near, and very-narrow for intermediate distance.


My impression is that the intermediate "neck" isn't even as wide as shown. Much compromise with strength needed and of course the cost of grinding the geometrically obscene curves.

In retrospect (or for next pair), if they aren't setting right in a week, go back to the doc and tell him.

got mine yesterday and so far i love them.  I can see again! :D  a little dizzy sensation from time to time and my brain is still trying to adjust some, but I love the clarity both near and far now!

I was wrong: it is Dollar Tree which sells readers for $1.

I wuz there today and got two more pair. A different pair of 1.25 which works good on PC, so I can use the ugly 1.25 pair for dirty-work like cellar plumbing (so I can see the leak going down my sleeve). And a pair of 1.75 which may be my book-reading strength (1.5 is long and 2.0 feels short).

I did order lenses with the mild astigmatism correction the Doc prescribed. Zenni Optical on-line sold me two pair and clip sunglasses for $21 shipped! (Cheaper than $39 Glasses which I used for years.) They come next week(?). That's single-vision in $7 frames. Bi-focals cost significantly more, and the up-price is different at different online stores. Watch the check-out options because they love to upgrade you.

Annoying tip: EyeBuyDirect has the prescription entry form rotated 90 degrees from how the docs and other sites write/take the numbers!! Normally OD and OS are two lines. EBY puts them in the columns. Which actually makes sense, but is *different*, and I was trying to put the wrong numbers in the wrong boxes. Anyway Zenni's prices tend to be better.

My field of view in the far distance region on my progressives does not come any where near the edge of the lense.  It's a narrow column right down the center of the lenses.  Perhaps the slight stigmatism correction messes with the width of the field of view.

me> Zenni Optical on-line sold me two pair and clip sunglasses for $21 shipped!

My Zennis came. 9 days from order. My mistake: $23 for two specs and one clip-on.

They seem fantastic for $7 frames, nevermind they come with free Rx lenses (single vision). The prescription is essentially correct. I see great. The PC "add" sees good too. Only complaint is Zenni sent several "sales emails" in that week; I've unsubscribed, we'll see if they stop.

That may be. As said, the optical geometry is obscene, there are various compromises. If it is limiting you, talk to the eyeglass sales staff, there are several approaches. Of course the "better" ones may cost more. And none can be perfect. (Why I lean to singles and bi-focals: the optics are "perfect" at the intended distances.)
