I also had my left eye cataract removed, and as a CPA I was also very disappointed in result. I'm not having my right eye done until ABSOLUTELY necessary. Turns out that being a high myope with macular puckers in both eyes are part of the problem, and it's taken almost a year for my brain to cope. Also I told Dr I wanted to have IOL for nearsightedness, but he gave me medium distance IOL, so only my right eye can see close now. Believe me I understand how distressing this can be.
BTW, there are IOLs to allow being near-sighted, but need to be ordered special, my doctor just took the IOL from the shelf. I'm not sure I would want it replaced with the lens I would have liked. My regular eye doctor said having a near-sighted IOL would be very unusual, but I wasn't told about that option.
