My brother is 65 and has reached the point of needing cataract surgery. He is told he has severe astigmatism in his right eye, and moderate astigmatism in the left. I don't know what this means in terms of diopters - he doesn't have his prescription. His understanding from talking to his doctor, is his left eye is dominant at distance, and his right eye dominant close up. He therefore proposed correcting the left eye for distance and the right for close-up, with the hope that he would see well enough at all distances not to need glasses at all. I know that some people (my own ophthamologist is one of them) fit contacts this way, but I wonder what percentage of people are unable to adjust to this. It seems if you can't adjust, then you have to wear bifocals all the time, and that having implanted lenses done this way is somewhat risky. In addition, the doctor is proposing to use a toric lens in the right eye, and to do a LRI procedure, whatever that is, in the left where the astigmatism is less severe. Does that make sense? Would using toric in both be better? I'd appreciate any comments or suggestions.
