According to this (not that rigorous) paper, cataract surgery can cost about $300. It improves vision and sometimes prevents blindness. Even if it’s not as cost-effective as a GiveWell-recommended charity, it can still illustrate the point about guide dogs.
As someone who has thought about cost-effectiveness, I agree that comparing willingness-to-pay-for-a-QALY/life is a more robust point. But for people who haven’t thought about this much, the more visceral preventing-blindness comparison might be better.
Maybe it would be worth someone checking that cataract-surgery charities like Sightsavers are passably cost-effective.
Even if it’s not as cost-effective as a GiveWell-recommended charity, it can still illustrate the point about guide dogs.
While it can illustrate the point I think there are two main issues:
If someone does get excited about what you’re saying and wants to donate, we don’t have anywhere with good evidence to recommend.
We shouldn’t put much stock in numbers like “$300/surgery” unless there’s been a good evaluation: it’s very common that you end up with much lower benefits than expected per dollar once you start digging in. For example, perhaps existing funders already cover the cases where the surgery would prevent blindness, charities aren’t willing to focus on the people with the worst vision, or the life expectancy of recipients is low because cataracts develop late in life.

Note that GiveWell did actually recommend Sightsavers (before their 2022 criteria changes), but for their deworming program, not their vision work.
They also looked into cataract surgery quite a bit in 2017 but didn’t end up with anything to recommend.

Agree.
