My brother is 65 and has reached the point of needing cataract\nsurgery. He is told he has severe astigmatism in his right eye, and\nmoderate astigmatism in the left. I don't know what this means in\nterms of diopters - he doesn't have his prescription.\n\nHis understanding from talking to his doctor, is his left eye is\ndominant at distance, and his right eye dominant close up. He\ntherefore proposed correcting the left eye for distance and the\nright for close-up, with the hope that he would see well enough at\nall distances not to need glasses at all. I know that some people\n(my own ophthamologist is one of them) fit contacts this way, but I\nwonder what percentage of people are unable to adjust to this. It\nseems if you can't adjust, then you have to wear bifocals all the\ntime, and that having implanted lenses done this way is somewhat\nrisky.\n\nIn addition, the doctor is proposing to use a toric lens in the\nright eye, and to do a LRI procedure, whatever that is, in the left\nwhere the astigmatism is less severe. Does that make sense? Would\nusing toric in both be better?\n\nI'd appreciate any comments or suggestions.
