A quick method for analyzing Hartmann-Shack patterns : application to corneal surgery

A quick method to analyze the Hartmann-Shack pattern is developed. This method allows to easily study the limitations of the system and to determine how to improve its capacity to measure a large range of aberration. It can treat situations presenting a difficulty when analyzing the detected pattern. As an application the case of eyes suffering from large amounts of aberration due to corneal surgery is considered.
