My brother had it in South Africa in the 90s when it was very new. He gave rave reviews and now so do I even 10 years later. I was in my 40s so they recommended the monovision, where they under-correct one eye so you can do without reading glasses a few more years. The nurses told me I would hate the monovision for one month and then would love it for years. They said I needed to ignore the temptation to go back to them in a few weeks complaining I could not stand it and correct both eyes.
Yes, the monovision was strange for a month. Then I had no need for reading glasses at all until after 55 y/o. Even now at 58 y/o I can read most print. I have power 1.00 reading glasses, the lowest I can find, for reading fine print.
