Abstract
Devices, systems, and methods that facilitate optical analysis, particularly for the diagnosis and treatment of refractive errors of the eye. Embodiments of the invention may facilitate the use of multi-modal diagnostic instruments and instrument systems, making it easier to acquire and fuse data from different measurements of the eye. For example, wavefront aberrometry may be fused with corneal topography, optical coherence topography and wavefront, optical coherence topography and topography, pachymetry and wavefront, etc. While some of these different optical datasets may be obtained simultaneously, it is often difficult and/or disadvantageous to attempt to acquire the images or other data at exactly the same time. Advantageously, both patient movement between measurements (and/or during a measurement sequence) can be identified, as well as changes in the eye itself (including those induced by the measurement, such as changes in the size of the pupil, changes in pupil location, etc.).
