CHAPTER 7 We found a similar trend in the evolution of the radius of both eyes of each patient. This parallelism between eyes is also found in control eyes, suggesting physiological mechanism acting bilaterally in the same way. 7.7. OUTLOOK This chapter closes the study of refractive surgery in this thesis. We have developed models for the quantitative evaluation of the anterior and also of the posterior corneal shapes. We have studied the changes in corneal shape induced by corneal refractive surgery both in-vitro (using platic models) and in vivo. We have compared optical outcomes of standard and optimized laser refractive surgery platforms with new generation algorithms in vivo, studied the impact of those changes on corneal spherical aberration and proposed methods of optimization of current algorithms (compesated The experience gathered studying ablation algorithms and their effect on optical outcomes is of great use in the the study of contact lenses. Contact lenses modify the refraction of the anterior surface of the eye, as well as the aberration patterns, as an ablation pattern does (by addition, rather than subtraction of material). Like corneal ablation, the fitting of contact lenses is a complex process (Sections 1.9 and 1.10) with many open questions (Section 1.10). As performed for corneal ablation, we will develop an artificial model eye to test contact lenses in vitro (Chapter 8) and will perform measurements on real patients, with rigid (Chapter 9) and soft (Chapter 10) contact lenses. Both studies on LASIK and contact lenses (eye models or patients) share methodology. Furthermore a mutual feedback between both areas is expected, with important implications on the design of ablation algorithms and lenses (i.e. multifocal lenses and presbyopic treatments) 182
