I am a firm believer in the philosophy that "Sometimes, less is more."
In Gary's case, being engaged in the printing business, he needed to keep sharp vision for reading and close-up. We did not want to take that away by correcting both eyes fully for distance. Since the left eye was already excellent for near, and he ws right-eye dominant, I advised treating only the right eye.
Gary was thrilled with his result. Now he has great distance vision with the dominant right eye, and kept good ner vision with the left. And in the process, we cut his costs in half by only doing one eye!
