Computer systems, programs, and methods can advantageously be used to process optical data. These approaches often involve modifying a first format data to a second format data, and are useful in simplifying the complications due to data from different wavefront systems, different aberrometer devices and aberrometer software versions, different clinical studies and different measurement conditions. A centralized database system can be used effectively in a clinical research setting, which can be a medical center, a college, or a research department in a company, or in other diagnosis or treatment facilities.
