I have just had cataract surgery on both eyes – the first in December and the second last month. I have worn glasses for over 65 years, having fairly severe short sight and moderate astigmatism in both eyes. I’ve worn varifocal glasses for many years, with high refractive index lenses to reduce their thickness (and weight), with complete success.
The current waiting time here in Berkshire for NHS cataract surgery is at least 6 months, so I decided to go privately. This left me with a wealth of options, but all of them would have left me having to wear glasses in some form.
Monofocal IOLs would correct my short sight, and enhanced monofocal my short sight and intermediate vision, but neither would correct the astigmatism. So-called toric IOLs will correct astigmatism, but a significant number of people then suffer from the bright light ‘halo’ effect. Also, astigmatism is a defect of the cornea, not the lens, and can change as you age. So, I decided to just go with a monofocal lens, but have my short sight significantly improved (i.e. the service the NHS also offers).
I won’t know the full effectiveness of this until I’ve had my eyes retested and new glasses prescribed in a few weeks’ time. (BTW, had I lived in Hampshire, the current NHS waiting time there is no more than a couple of weeks!)
So, in answer to the OP’s question is paying for the surgery any real value, in my case, probably no, but had I not suffered from astigmatism, I would have opted for enhanced monofocal lenses, and therefore no need for glasses.
