I had my IOL's for cataracts done 8 months ago. Being a physician, I'm not interested in the hype of the latest gadget, so I went with standard old monofocal IOL's. My ophthalmologist agreed that would also be his choice, "but I have to offer you all the choices". Since I've worn Varifocals for 30 years, I still happily wear Varifocal specs. My view is the old KISS -- keep it simple.
Can I see better? -- yes, but it has not been the "miracle" some report. I do appreciate the vibrant colors now, though, and my vision is now corrected to 20/15 in both eyes. In addition, my eye pressure dropped, and I've been able to stop medication for that. All good.
