Result of my surgery:
I had surgery on my left eye because the cataract was much worse in that eye (and astigmatism) . I wanted to target my left eye for a computer monitor. I got an AcrySof iQ Toric IOL which is 15.0 D, 3.00 CYL.
I'm happy with it. As it turns out my focal point after 1 month is around 31 inches with a depth of focus providing a comfortable range from 27 to 36 inches. Functionally I can read most text closer still if I need to, but blurry, up to around 16" away. On the other hand, I notice I can be 8 feet away and still make out the smallest text that might appear in television programming on a 32" non-HD TV that I have in my office. The absence of astigmatism in my left-eye has been awesome. I can see at a distance at around 20/30 and I had thought that I would see sharply at computer distance and then everything else would be blurry. From a practical standpoint, not so. I walk around feeling like I have 20/20 vision unless I'm trying to read the score on a TV twenty feet away, or a grocery display at 20 feet or more, etc.
With that realization, I have thought about bringing the target focal point of my right eye in a little closer. I'm using a contact lens in my right eye that brings my focal point in about 10 inches. I starts bringing into focus at about the point they start falling out of focus with my left eye, at around 26 inches, and then gives me another 10 inches of range to around 15 inches. This is an astigmatism correcting contact lens, but it can't correct it as perfectly as the IOL has with my left eye.
But given my right eye had always been my dominant eye, does this cause some issues if I have it set as the nearer focus eye after cataract surgery on it? I'm wondering if my right eye as the dominant eye will continue to try to struggle to get into focus at the longer distances 27" to 36" where my left eye can see clearly.
Would I be better off targeting my right eye to match where my left eye is now, and then use Lasik to bring my left eye in nearer (or correct it to nearer vision with a contact lens)?
My plan is to wear glasses I'm not working at my desk and just take them off when I need to read something (or else just wear a distance contact lens in my right).
Had I realized how much overall, functional depth of focus my left eye IOL provides for my day to day activities, I would have targeted it as the nearer vision eye since it is my non-dominant, and planned on having my right eye targeted at where my left eye is now.
Thanks for any advice!
