For sure it’s totally awesome that @CairoCarol has been saved from functional blindness by modern medicine, even if “modern” was a few years ago.
I too have developing cataracts that have been cooking in there for a decade or so, and are now beginning to be annoying even in daytime. I also have astigmatism and ordinary age-related presbyopia. Right now I manage the latter two with monovision (one near + one far) contacts or glasses. The glasses offer sharper vision, at the annoyance of glasses. I found switching to monovision to take about 3 hours to get used to. It truly is amazing how well that worked. For me; perhaps not for you (any you). FWIW I wore progressives for years and had no problem adapting to them either. I suspect the ease of those two adaptations are related somehow.
Back in the day I had excellent eyesight, 20/12 uncorrected both sides. That started fading in college.
Prior to the cataracts becoming an issue I had looked at LASIK, RK, etc. In each case the choice amounted to trading [OK-minus uncorrected vision plus excellent corrected vision] for [OK-plus uncorrected vision with no chance to further improve it by correction, plus the medium risk of visual artifacts and the small risk of disaster]. I stood pat because I had a lot to loose and the gains seemed incremental at best.
The cataracts are changing that calculus now because they’re finally getting obvious and seem to be gaining speed. Or at least the perceptual consequences are gaining speed even if the mechanical deterioration is as slow as ever.
At my last visit with the optho the advice was “not yet”. I bet that changes this time.
But I’m still looking at trading a good hand for a maybe better one, a maybe equivalent one, and a maybe worse / just mediocre one. With a small chance of disaster. Anyone who’s ever played 5-card draw poker certainly knows the feeling of discarding what turned out to be better cards than you drew.
Our own @pullin suffered an ocular surgical disaster just within this last year-ish. He’s written about it a time or two and anyone considering ocular surgery ought to search up those posts. IIRC, one eye came out fine, while the other had a major league surgical oops that left him functionally blind on that side. It’s since been fixed mostly, so no longer disastrous in his view. But still an awful experience with a poor total outcome.
A sobering reminder that low odds of a failure are not zero odds of a failure.
One of the “advantages” of starting out already screwed, as dear @CairoCarol seems to have been from birth, is that they have relatively little to lose long term, so the vagaries of chance are almost all to the upside. Similar considerations apply to treatments for other disastrous diseases. e.g. chemotherapy does a lot of collateral damage, but it (often) beats the alternative.
With all that long-winded intro, here’s sort of the TLDR I personally came to and that will guide my own decisions going forward.
If the failure / disaster rate is X%, then I need to be suffering now from more than X% degradation from my non-cataract case to make the trade even worth thinking about. And once the degradation is worse than the risk, we start the conversation, but actually doing something probably needs the degradation to be 3 or 4x what the risk rate is. Because glasses, contacts, and halos are all very minor impositions in my life, whereas a serious failure would be a serious imposition.
In truth, I’m more concerned about getting a merely adequate result that can’t be as well-corrected as my current natural vision more than I fear the true disaster. When those lines cross is when I act. As of today that seems to me to be a reason to wait, not act.
