Research in orthokeratology. Part VIII: results, conclusions and discussion of techniques

In this paper, the results, discussions and conclusions concerning selected variables relative to orthokeratological effects and procedures are presented. The data, clinical observations and subsequent analyses suggest that corneal modification with contact lenses is not clearly understood. Hypothesis are offered to explain certain results obtained, to account for observed discrepancies and to collectively assemble a rational understanding for the effects of contact lenses on purposeful corneal modification.
