The purpose

By using a new software two consecutive laser treatments have been combined to correct the distance vision and to provide a near vision component in addition to the first treatment. This study will help us to answer 2 questions: 1. How accurately this combined technique corrects distance and near vision 2. Whether the correction is adequate to remove the complete need for supplementary near spectacles
