A friend needs cataract surgery and a mutual friend who's an optometrist was explaining the benefits to him. The optometrist was also explaining the benefits of leaving the eye a little short sighted, as I mentioned above.
Not sure I understand all of that Jeffrey but I assume that the toric lenses correct for astigmatism.
My main problem, since I was 14, was short sight and acute astigmatism. However, the astigmatism has varied greatly over the years so I doubt a fixed solution is possible.
When I had my first cataract done, the lens gave me good distance vision but it wasn't until I had the second one done a couple of years later that I could really see the difference as I was now unhindered by one bad eye to go with the good one!
Incidentally, I was offered the option of having the second lens optimised for reading distance - the idea is the brain quickly learns which eye to use, dependant on what you are looking at - but the idea terrified me and I asked for both eyes to match!
After this, my astigmatism was considerably reduced to the extent that my optician said that I didn't really need glasses for distance vision.
However, having worn glasses full time since I was 14, I was perfectly used to them and I could also see two very good reasons not to ditch my glasses.
20 years or so earlier I reached the stage where I needed reading glasses. At that time I had an office on the first floor and a lab on the lower ground floor. You can probably guess what happened: I'd go down to the lab and want my reading glases which, of course were sitting on my desk two floors up!
The next pair of glasses I had were bifocals, which solved that problem - so there was no way I was going back to a pair of glasses that i only wore sometimes (and were never where I wanted them!).
Also, by now I was having problems with the computer because it was too far away from the reading zone and too close for distance, so I'd taken to perching a pair of +1 ready readers on my nose in front of my normal glasses! So, varifocals - which are really trifocals - seemed like the perfect solution - and they were!
I've always had my reading prescription cranked up a notch for close work so perhaps that's why I don't quite understand your last sentence, or is that what you mean?
