Excimer laser aberration correction system is able to create customised ablation, not only for the correction of emmetropia, but also to reduce higher order ocular aberrations. It can reduce aberrations and eliminate night vision problems caused by LASIK surgery. Excimer laser aberration correction system includes two parts: wavefront aberration measurement using subjective aberrometer WFA 1000 and wavefront aberration correction using excimer laser system. We introduced the concept of the wave front aberration of the living human eye and the methods of evaluation; fitted the data to a Zernike series to reconstruct the wavefront aberrations of living human eye. We studied the principle of excimer laser aberration correction system and the block diagram of system controlling software. The mechanism of action of excimer laser corneal ablation, "flying-spot" scanning, active eye ball tracking, as well as laser energy closing loop controlling key technologies had been discussed. Our research results have been applied to the excimer laser aberration correction system. During animal practice, it has achieved satisfactory outcomes.
