INTRODUCTION 1Chapter Chapter 1 - Introduction The goal of this doctoral thesis is to study the physical phenomena involved in corneal ablation for refractive surgery, and in the fitting of contact lenses on the cornea. In Chapter 2 we will describe the techniques and procedures developed in this thesis for the measurement of the geometry (and changes in geometry) of optical surfaces, the optical quality they provide, and their visual impact. Chapters 3, 4 and 5 present in vitro studies of physical factors involved in laser ablation. Chapters 6 and 7 are devoted to the measurement of the posterior surface of the cornea, and its longitudinal change after refractive surgery in patients. Chapters 8, 9 and 10 present studies of different aspects of the fitting of contact lenses (soft and rigid, monofocal and multifocal, positive and negative, in vitro and in vivo), and the visual outcomes that these lenses produce. In this chapter we introduce the main background and key concepts regarding the approach followed in this thesis. We present a short review of aberrometry on the human eye, introducing basic concepts, history and its state-of-the art, along with the most relevant results to date using aberrometry. We present an overview of the other important techniques for this thesis. Finally, we will review Laser Refractive Surgery and Contact Lenses, in relationship with geometrical changes of the ocular surfaces and optical aberrations of the cornea. We will enumerate open questions in the field that we will address in the thesis. 17
