Abstract


The paper analyzes the opportunity to use contact lenses in the field of orthokeratology and their effect on the level of visual comfort for human subjects who have myopia or keratoconus. in the first part of the paper are reviewed some general aspects related to the importance of the characteristics of hard contact lenses for the development of the visual correction process, the management of human subjects with visual dysfunction, and, for the second part to identify the set of optometric evaluations that must form a portfolio of structural analysis. in the third part of the paper, the authors present case studies for subjects wearing orthokeratology contact lenses to identify the evolution of the visual aid procedure and the moments and situations where the most effective, complete and useful level of comfort can be achieved. The results and conclusions from the analysis are presented at the end of the paper.
