Often, in people who are of presbyopic age (i.e. need a different prescription for reading than for distance, or use bifocals, or take their distance glasses off to read), LASIK can be a challenge. We do not want to take away too much function at near in order to achieve good clarity at distance.
In Maureen's case, we aimed for a slight undercorrection, so that she would have good function at an 'intermediate' range from about 2 feet to 8 feet. This enables her to work in her office, counsel patients across a desk, watch TV, etc. without glasses. She does not mind wearing a little magnification for reading.
