[Wavefront analysis and adaptive optics].

In this paper we attempt to provide an overview of the principles of wavefront measurement. We also discuss the operational principles of different systems currently present on the market including their advantages and disadvantages. Moreover, we speculate on current and possible future implications of this new technology in the laser refractive surgery. Adaptive optics are explained in the context of "customized ablation" and preoperative verification of the desired results. Finally, the first international clinical results of wavefront guided excimer laser surgery are reviewed and critically commented.
