Evaluation of a laser used in ophthalmologic surgery. A test substrate is formed from a homogenous material of controlled water content that ablates at a rate approximately that of human corneal tissue. A first non-contact surface topographical analysis of the test substrate is performed prior to laser ablation. Laser ablation is performed on the test substrate. A second non-contact surface topographical analysis of the test substrate is performed. The second surface topographical analysis is compared with the first to evaluate the surgical laser. The analysis is used to calibrate the laser. The data also is used to enhance the predictive value of a self-educating neural network. The non-contact surface topographical analysis is performed by rasterstereography, videokeratography, laser holography, scanning laser ophthalmoscope, optical coherence tomography, and scanning white light interferometry.
